Causes, symptoms, treatment, and more

Fatigue and nausea are common symptoms that often occur together. In some cases, these symptoms may develop as a result of lifestyle factors, such as poor sleep or diet, or lack of exercise. In other cases, they may signal an underlying medical condition that requires treatment.

Fatigue is a term that describes a lack of energy or a feeling of tiredness or sluggishness. Nausea is a feeling of discomfort in the stomach or a feeling of needing to vomit.

This article outlines the potential causes of combined fatigue and nausea and lists the medical treatments and home remedies that may help alleviate these symptoms. We also provide advice on how to prevent fatigue and nausea and when to see a doctor.

Fatigue and nausea can co-occur as a result of:

• lifestyle factors
• short-term, or acute, illnesses
• long-term, or chronic, conditions

Some possible causes of fatigue and nausea are outlined below.

Lifestyle factors

The following lifestyle factors may cause fatigue and nausea:

• staying awake too late
• not getting enough sleep
• eating too much
• eating too late at night
• drinking too much alcohol the night before
• using recreational drugs
• lacking physical activity
• overexerting oneself
• being jet-lagged

Infections

Certain infections may also cause symptoms of fatigue and nausea. Examples include:

• bacterial infections, such as:
  • Helicobacter pylori (H. pylori) infection
  • Escherichia coli (E. coli) infection
  • chlamydia
• viral infections, such as:
  • influenza
  • Epstein–Barr virus (EBV)
  • hepatitis
  • poliovirus
  • Ebola virus
  • malaria
  • dengue fever
• parasitic infections, such as:
  • hookworm infections

Psychological causes

Mental health issues can sometimes cause physical symptoms, including fatigue and nausea. Examples include:

• anxiety
• stress
• depression
• loss and grief

Hormonal issues

Fatigue and nausea can sometimes occur as a result of a condition that affects the hormones or the endocrine system that makes the hormones. Examples include:

• hyperthyroidism
• hypothyroidism
• hyperparathyroidism
• hypercalcemia
• Addison’s disease

Neurological conditions

Issues that affect the nerves and the nervous system may also cause symptoms such as nausea and fatigue. Examples include:

• migraines
• epilepsy
• concussion
• traumatic brain injury (TBI)
• multiple sclerosis (MS)
• brain tumor

Other conditions

Other conditions could also cause nausea and fatigue with or without additional symptoms. Some examples include:

• reactions to animal bites or stings
• food poisoning
• food intolerances or allergies
• celiac disease
• inflammatory bowel disease (IBD)
• peptic ulcer
• hypertension
• heatstroke
• premenstrual syndrome (PMS)
• endometriosis
• sleep apnea
• chronic fatigue syndrome
• diabetes
• kidney disease
• liver cirrhosis, or liver failure

Fatigue and nausea are common during the early stages of pregnancy. Doctors use the term “morning sickness” to refer to nausea and vomiting during pregnancy, although these symptoms may occur at any time of day. A 2014 study notes that morning sickness occurs in around 85% of pregnancies.

If there is any possibility that a person may be pregnant, they should take a pregnancy test. If they are not pregnant, they should see their doctor to determine the cause of their morning nausea.

Feeling nauseous upon waking up may simply be the result of poor sleep or an upset stomach from the night before. However, it could also signal a more chronic underlying health issue.

It is fairly normal for a person’s energy levels to dip after eating. This happens because the body redirects blood to the digestive system to help break down food in the stomach.

Eating too much may cause a large dip in energy levels since the body has more food to digest. Overeating may also cause feelings of fullness or nausea.

Symptoms of fatigue and nausea after eating can sometimes signal a digestive issue. Other possible symptoms of a digestive disease include:

• difficulty swallowing
• acid reflux
• heartburn
• vomiting
• bloating
• abdominal pain
• belching or flatulence
• constipation
• diarrhea
• bowel incontinence
• blood in stool
• unexplained weight gain or weight loss

The treatment for fatigue and nausea depends on the underlying cause. Treating the cause should help eliminate or control the symptoms. Chronic conditions may require a long-term treatment plan.

Doctors may also prescribe treatments for the symptoms themselves. For example, a doctor may prescribe antiemetic drugs to reduce nausea and vomiting.

Certain home remedies may help manage the symptoms of fatigue and nausea. Some examples are outlined below.

Home remedies for nausea

The following home remedies may help settle an upset stomach and reduce feelings of nausea:

• sipping a cold drink
• drinking ginger or peppermint tea
• eating foods containing ginger, such as ginger biscuits or candied ginger
• eating multiple small portions
• getting a lot of fresh air
• finding distractions, such as listening to music, watching a movie, or reading a book

In addition, people should avoid the following:

• preparing or eating strong-smelling foods
• eating foods that are spicy, fried, or greasy
• eating too fast
• drinking while eating
• wearing clothing that is tight around the waist or abdomen
• lying down shortly after eating

Home remedies for fatigue

The following home remedies may help reduce fatigue:

• eating smaller meals and healthful snacks every 3–4 hours
• gradually decreasing caffeine intake over the course of 3 weeks
• limiting alcohol intake and avoiding alcohol before bedtime
• drinking more water to prevent dehydration and associated fatigue
• gradually increasing physical activity
• reaching or maintaining a moderate weight
• going to bed and waking up at the same time each day, even on weekends
• avoiding daytime naps
• establishing or maintaining a relaxing bedtime routine
• reducing stress levels through one or more of the following:
  • working out
  • practicing yoga or tai chi
  • spending time with friends
• receiving counseling or cognitive behavioral therapy (CBT) for fatigue caused by stress, anxiety, or low mood

Experiencing fatigue and nausea is not always a cause for concern. Sometimes, these symptoms are the result of poor lifestyle habits. Changing these habits should lead to an improvement or reduction in symptoms.

However, people should see a doctor if they experience severe, persistent, or worsening episodes of fatigue and nausea.

It is important to seek immediate medical attention for fatigue and nausea that are accompanied by any of the following symptoms:

• chest pain or pressure
• difficulty breathing
• slurred speech
• persistent confusion
• continuous or repeated vomiting
• fever
• yellowing of the skin or eyes
• suicidal thoughts

The above symptoms may indicate a serious underlying medical condition that requires prompt medical treatment.

The outlook for people experiencing combined fatigue and nausea depends on the underlying cause of these symptoms.

Fatigue and nausea are not always a cause for concern. This combination of symptoms sometimes goes away following appropriate lifestyle adjustments, such as changes in eating, sleeping, or exercise habits.

However, severe, persistent, or recurrent episodes of fatigue and nausea can indicate an underlying medical condition that requires treatment. In some instances, it may take time for a doctor to diagnose and treat the cause. Once a doctor has established a diagnosis and a treatment plan, a person will typically find relief from these symptoms.

It may not be possible to prevent all causes of fatigue and nausea. However, the following factors may reduce a person’s risk of developing these symptoms:

• staying hydrated
• limiting alcohol and caffeine intake and avoiding either before bedtime
• avoiding large meals and eating late at night
• getting plenty of sleep each night
• following basic personal hygiene to help prevent infections
• eating a healthful diet and exercising regularly to reduce the risk of health conditions that can cause fatigue and nausea
• alleviating stress through one or more of the following:
  • mindfulness meditation
  • breathing exercises
  • yoga or tai chi
• seeking therapy for mental health issues, such as anxiety or depression

Fatigue and nausea are symptoms that commonly occur together. In some cases, they are the result of lifestyle habits, such as poor sleep or diet, or lack of exercise. In other instances, they may signal an underlying mental or physical health issue that requires treatment.

Sometimes, a person may experience symptom relief after using home remedies to aid sleep, alleviate stress, or improve diet. However, if these changes do not lead to an improvement in symptoms, a person should see their doctor.

Anyone who experiences severe, persistent, or recurrent episodes of fatigue and nausea should seek a medical diagnosis and treatment. Following appropriate treatment, most people should experience an improvement in their symptoms.

What are fatigue and nausea?

Fatigue is a condition that is a combined feeling of being sleepy and drained of energy. It can range from acute to chronic. For some people, fatigue can be a long-term occurrence that affects their ability to carry out daily activities.

Nausea occurs when your stomach feels uneasy or queasy. You may not actually vomit, but you may feel as though you could. Like fatigue, nausea can stem from many causes.

Seek immediate medical help if your fatigue and nausea are accompanied by:

• difficulty breathing
• headache
• chest pain
• fever
• thoughts of harming yourself
• yellowing of the eyes or skin
• slurred speech
• repeated vomiting
• lasting confusion
• abnormal eye movement

Lifestyle changes can frequently help reduce fatigue and nausea. Schedule an appointment with your doctor if you don’t feel rested even after a full night’s sleep.

If you have cancer, ask your doctor about interventions that could enhance your energy levels.

This information is a summary. Always seek medical attention if you’re concerned you may be experiencing a medical emergency.

Healthy habits, such as getting enough sleep, eating healthy foods, and exercising regularly can help you find relief from fatigue and nausea. Avoiding bad habits such as smoking, drinking excess alcohol, or abusing drugs can also help reduce fatigue and nausea.

Your doctor may prescribe medications to treat an underlying condition.

Home care

Staying hydrated by drinking clear liquids can help relieve fatigue and nausea. Maintaining a healthy activity level that doesn’t involve exercising excessively can also help prevent or reduce these symptoms.

Fatigue can impact your overall well-being. Take the following steps to prevent the onset of fatigue and nausea:

• Get enough sleep each night (typically between 7 and 8 hours).

main causes and treatments

If you are constantly sick and feel weak in the body, then you may have serious health problems. Do not ignore these symptoms and see your doctor for advice and diagnosis. Early identification of the causes and timely treatment will help stop the progression of the disease and maintain health.

It often happens that after a heavy meal or physical exertion, a person begins to feel nausea and weakness in the body. But also such symptoms can occur for no apparent reason. In this article, we will talk about common causes of nausea and weakness and how to treat them.

One of the most common causes of nausea is a disturbance in the functioning of the stomach and intestines. This can be irregular meals, eating fatty and heavy foods, allergies to certain foods, viral and infectious diseases. It is also worth mentioning stress as one of the reasons.

Weakness, on the other hand, can occur both with insufficient intake of nutrients into the body, and with overwork, illness, stress, and also due to low blood pressure. Often this is the first symptom of various diseases.

If you experience such symptoms, then first of all, you should consult a general practitioner or gastroenterologist to find out the causes. Depending on the diagnosis, the doctor can prescribe the appropriate treatment and diet, as well as prescribe the necessary medications. In addition, moderate physical activity, regular water intake, and avoiding alcohol and smoking can help reduce nausea.

Why does nausea and weakness occur in the body: causes and treatment

Nausea and weakness in the body can occur for various reasons. The most common of these are:

• Disorders of the digestive system. For example, eating unsafe or expired food can cause nausea and weakness in the body. It can also be caused by diseases of the stomach, liver, pancreas or intestines.
• Stress and psychological problems. Often nausea and weakness in the body occur against the background of emotional experiences, unrest and anxiety. They may also be associated with depression or sleep disturbances.
• Infectious diseases. Some illnesses, such as the flu, SARS, gastroenteritis, and others, can cause nausea and weakness in the body.

To treat nausea and weakness in the body, it is necessary to find the cause and eliminate it. If this is due to disorders of the digestive system, it is necessary to adhere to proper nutrition, avoid fatty, spicy and spicy foods. In the case of infectious diseases, antibacterial or antiviral therapy may be used. If the cause is stress or psychological problems, it is recommended to seek help from a psychiatrist or psychotherapist.

As an additional measure, symptomatic treatment can be given. For example, consuming ginger, prescription drugs, or folk remedies can help with nausea. It is also recommended to rest more, drink plenty of fluids and take measures to strengthen immunity.

Stress and fatigue as the main cause of nausea and weakness

Often a person feels nausea and weakness, even if he does not have any diseases. In this case, mental disorders such as depression, anxiety, stress, as well as exercise and fatigue can be the cause.

Stress has a strong effect on our body, including the central nervous system and the respiratory and digestive organs. This can lead to disruption of the stomach and intestines, which can cause nausea, vomiting, and weakness.

Frequent worries, lack of sleep and fatigue can also lead to a weakened immune system and an increased risk of viral diseases. A person may experience pain in the muscles and brain, a decrease in strength, problems with vision and coordination of movements.

To prevent nausea and weakness, you need to monitor your emotional state, avoid strong emotions and stress, as well as get enough sleep and eat right. Developing healthy habits such as regular exercise, meditation and yoga will help boost your immune system and deal with the negative effects of stress and fatigue.

Overeating and malnutrition

Overeating can be one of the main causes of nausea and weakness. It happens when a person eats too much food in a short amount of time. The stomach does not have time to digest a large amount of food, which causes a feeling of discomfort. In addition, overeating can lead to heartburn, vomiting, and constipation.

Another factor that causes nausea and weakness is malnutrition. If a person consumes too much fatty, spicy or sweet food, it can damage the stomach and irritate its walls. This can lead to nausea, discomfort, and weakness.

Improper nutrition can also lead to chronic diseases such as obesity, diabetes and cardiovascular disease. With such diseases, nausea and weakness are often observed, especially after eating.

• To avoid overeating and malnutrition, it is recommended:
• Eat slowly – chew the skin of the food.
• Avoid snacking on a quick hand.
• Reduce your intake of fatty, spicy and sugary foods.
• Eat smaller meals more often.

Intoxication of the body

Intoxication of the body is the process of contamination with toxins that can enter the body from the environment (air, smoking, alcohol, food, water) or form inside it (metabolism, infections, cancer cells).

Complications of intoxication can lead to various physiological changes in the body: nausea, vomiting, dizziness, weakness, pain in the abdomen or at the site of the lesion. One of the most important complications is a violation of the immune system.

The treatment of intoxication consists primarily of eliminating the cause of the cluttering of the body. However, there are ways to alleviate the condition in case of poisoning. This may be the use of sorbents (activated carbon, polyphepan, kaolin), an abundant water regime during infusion therapy and drugs to reduce the symptoms of acute intoxication.

One of the most important principles for the prevention of intoxication is the observance of food and rest hygiene, the cessation of smoking and drinking alcohol, as well as the use of natural products and high quality water.

• Be mindful of your body and health
• Take care of your food and rest hygiene
• Get regular preventive health check-ups
• Avoid smoking and drinking alcohol
• Use natural products

Gastroesophageal reflux

Gastroesophageal reflux (GER) is a dysfunction associated with the backflow of stomach contents into the esophagus. This irritates the lining of the esophagus and can cause nausea, vomiting, and weakness in the body.

Symptoms of GER may include regurgitation, ie, eruption of food from the stomach into the mouth, frequent belching, chest pain, discomfort when swallowing food, and even asthmatic attacks. Often this condition is accompanied by increased acidity of the stomach, which worsens the general condition.

There are many treatment options for GER, including lifestyle changes, drug therapy, and surgery. Some of the recommendations include changing your diet and eliminating excess weight. Other tips may include avoiding smoking and reducing alcohol consumption.

• Medical therapy often uses drugs that reduce gastric acidity, such as proton inhibitors and histamine receptor antagonists.
• Surgical methods, such as fundoplication, may be used when conservative methods fail and/or there is severe damage to the esophagus.

Medications and medications

Some medications and medications may cause nausea and weakness in the body. For example, many antibiotics can cause unpleasant side effects such as stomach upset, nausea, and vomiting.

When taking medicines, it is imperative to take into account individual tolerance and the recommendations of a doctor. Some women may experience nausea while taking contraceptives, especially in the first few weeks of use.

If you notice that taking a medicine causes nausea and weakness in the body, consult your doctor immediately, who can prescribe an alternative medicine or change the dosage of the existing one.

It is important to remember that self-medication can lead to more problems and aggravate symptoms. Always consult your doctor before taking any medicine and follow his recommendations.

Acute and chronic poisoning

Acute poisoning is a condition resulting from the rapid exposure of the body to poison, toxic substances or other harmful compounds. Acute symptoms may appear within minutes or hours after exposure to toxins. These include: nausea, vomiting, weakness, dizziness, loss of consciousness, fainting, respiratory failure and other manifestations.

Chronic poisoning occurs gradually when the body is in contact with toxic substances for a long time. Most often this happens when working in hazardous industries, where harmful gases, vapors and dust from various chemical compounds are released. Symptoms appear gradually, they are difficult to identify in the initial stages.

To avoid poisoning, it is necessary to take preventive measures, prevent the ingress of harmful substances into the body and observe safety measures at work. In the event of an acute form of poisoning, you must immediately call an ambulance and perform first aid. In chronic poisoning, it is also necessary to seek medical help to identify the causes and subsequent treatment.

Pregnancy and toxicity

Pregnancy is accompanied by many changes in a woman’s body, including changes in hormone levels and an increase in the amount of blood in the body. Most women develop morning sickness in the first months of pregnancy, which can manifest itself with various symptoms, such as nausea, vomiting, dizziness, weakness, etc. and tastes. It can start as early as early in pregnancy and last for weeks or months.

To relieve the symptoms of toxicosis, a woman should monitor her diet, eat small meals often and choose easily digestible foods. It is also desirable to increase rest time and reduce physical activity. If the symptoms do not go away after the first months of pregnancy, you should consult a doctor for advice and possible treatments.

• It is important to understand that each pregnancy is individual and each expectant mother may have her own experience of toxicosis;
• Some women may experience toxemia throughout pregnancy, while others will resolve it in a few weeks or months;
• Toxicosis may affect the quality of life of the expectant mother, but usually does not adversely affect the development of the child.

Do not forget that this is a natural process associated with changes in a woman’s body. It is important to pay enough attention to your health and consult a doctor if the toxemia becomes unpleasant and difficult to manage.

Thyroid problems

The thyroid gland plays an important role in regulating metabolism and providing energy. If its function is impaired, it can lead to various symptoms, including nausea and weakness in the body.

Hypothyroidism is a condition in which the thyroid gland does not produce enough hormones. Symptoms may include fatigue, weakness, digestive problems, and nausea. Treatment may include taking synthetic thyroid hormones to compensate for the deficiency.

Hyperthyroidism is a condition in which the thyroid gland produces too many hormones. Symptoms may include nausea, weakness, diarrhea, and weight loss. Treatment may include drugs to reduce thyroid hormone production or removal of part of the gland.

Chronic thyroiditis is a disease in which the immune system attacks the thyroid gland, causing inflammation and damage. Symptoms may include fatigue, weakness, and nausea. Treatment may include synthetic thyroid hormones and drugs to lower immune activity.

For the diagnosis and treatment of thyroid problems, you need to see an endocrinologist and undergo regular medical examinations.

Migraine and headache

Migraine is a form of headache characterized by sharp and throbbing pains in the head. It may be accompanied by nausea, vomiting, a feeling of weakness, and increased sensitivity to light and sound. For many people, migraine is a chronic disease that greatly affects their quality of life.

Headache is a general term that describes various forms of pain in the head. It can be caused by many reasons, such as tension in the muscles of the head and neck, changes in blood pressure, nervous disorders, and others.

Treatments for migraine and headaches include analgesics, anti-inflammatory drugs, head and neck massage, relaxation exercises, lifestyle changes (stress avoidance, healthy eating, adequate sleep), and others.

If a headache becomes a frequent occurrence, it is necessary to consult a neurologist, who will help to identify the cause of the pain and choose the most effective treatment.

Infectious diseases and viruses

One of the causes of persistent nausea and weakness can be infection of the body with viral or bacterial infections. These can be such common diseases as influenza, SARS, CARS-CoV-2 (COVID-19), or other less known, but no less dangerous infections.

Symptoms of infectious diseases include not only nausea and weakness, but also fever, headache, muscle and joint pain, cough, runny nose, sore throat and others. Such diseases can make life difficult and require treatment by a doctor.

In the treatment of viral infections, symptomatic therapy is often used to reduce symptoms: they take antipyretics, antitussives, antiviral and other drugs to help eliminate unwanted manifestations of the disease.

• It is important to remember that if you suspect an infectious disease, you should immediately consult a doctor and do not try to treat yourself. In some cases, insufficient therapy can lead to serious consequences and complications.
• It is also very important to take preventive measures to prevent infection, such as washing your hands, avoiding contact with people who are sick, wearing masks, etc.

In general, if you experience persistent nausea and weakness, you should definitely consult your doctor to find out the cause of these symptoms.

Alcohol and smoking

Smoking and alcohol consumption are major health risk factors. They can cause many negative effects, including nausea and weakness in the body.

The nicotine in tobacco causes vasoconstriction, which can reduce the supply of oxygen to organs and tissues. In addition, smoking increases the risk of heart disease and lung cancer.

Alcohol, in turn, can cause weakness and nausea by irritating the walls of the stomach and causing a decrease in blood glucose levels. Long-term alcohol consumption can also lead to cirrhosis of the liver and other diseases.

The best solution for those who suffer from constant nausea and weakness is to stop smoking and drinking alcohol. A healthier alternative would be to strengthen the immune system, eat right, exercise moderately, and maintain a healthy lifestyle in general.

Allergies and autoimmune diseases

Allergic reactions can cause permanent nausea and weakness in the body. Allergy sufferers experience completely different symptoms, but often they have persistent gastrointestinal problems such as nausea, vomiting, and diarrhea. This is due to the fact that during allergies, histamine is released in the body, which can cause the smooth muscles of the stomach and intestines to contract, which leads to the fact that their functioning is impaired.

However, there are other causes of persistent nausea and weakness in the body. Autoimmune diseases such as Hashimoto’s disease and systemic lupus erythematosus can cause similar symptoms. With such diseases, the body’s immune system is sent to destroy its own tissues, which leads to many health problems, including the functioning of the gastrointestinal tract.

The treatment of allergies and autoimmune diseases can be different and depending on what kind of pathology the person is diagnosed with. It is recommended to contact experienced professionals to determine the causes of such health problems and develop appropriate treatment.

Diseases of the digestive system

The digestive system is responsible for breaking down food into elements needed by the body. It consists of a number of organs: the esophagus, stomach, small and large intestines, liver and pancreas. Each link in this chain plays an important role in the process of digestion, and disorders in the functioning of any organ can lead to diseases of the digestive system.

One of the common diseases of the digestive system is gastritis. It occurs when inflammation of the mucous membrane of the stomach, which leads to disruption of its work. Symptoms of gastritis are nausea, vomiting, abdominal pain, acidity, and even bleeding in the intestines.

Stomach ulcer is another disease that can result from indigestion. The reason for its appearance is the formation of an ulcer on the gastric mucosa or duodenum. Symptoms of an ulcer are burning in the epigastric region, nausea and vomiting, heartburn, and increased pain after eating.

Pancreatitis is a disease in which the pancreas becomes inflamed. It can result from alcohol use, eating disorders, and infection. Symptoms of pancreatitis include severe abdominal pain, vomiting, nausea, and even fever.

To prevent and treat diseases of the digestive system, it is necessary to monitor your diet, eliminate bad habits, undergo regular medical examinations and, if you have certain symptoms, consult a doctor for professional help.

Peculiarities of work in hazardous industries

Work in hazardous industries requires special conditions and precautions on the part of workers. One of the main factors on which the health of workers depends is the emission of harmful substances into the atmosphere.

During the production of chemicals, coal and other products at high temperatures, many hazardous substances are released into the atmosphere, which can adversely affect the human body.

In hazardous industries, workers may also be exposed to specific hazards such as noise, vibration, and radiation. When in contact with hazardous substances, workers must use protective equipment and strictly observe safety precautions.

Failure to follow the rules and precautions in hazardous industries can lead to various health problems. Toxicity of substances, excessive noise and vibration levels can cause diseases such as lung cancer, bronchitis, allergic reactions, etc.

Therefore, workers in hazardous industries should carefully monitor their health, use modern protective equipment whenever possible and seek medical attention if any physical symptoms appear.

Dehydration and electrolyte disturbances

Dehydration is one of the main causes of constant nausea and weakness in the body. Sometimes we do not notice how much fluid we lose per day during everyday activities, such as working at a computer for a long time, sitting in the office, riding public transport in the heat, etc.

Violation of the water-salt balance can also lead to nausea and weakness. As a rule, it occurs with excessive sweating from overheating, excessive fluid loss can lead to the fact that the body’s water-to-salt ratio is disturbed, which will negatively affect well-being.

In order to avoid dehydration and disturbance of the water-salt balance, it is necessary to provide the body with a daily intake of a sufficient amount of liquid. It is recommended to consume at least 1.5-2 liters of water per day, as well as vegetable and fruit juices, saline solutions (for example, Regidron) and consume potassium-rich foods such as: bananas, kiwi, oranges.

In addition, it is important to consider that at elevated temperatures or physical exertion, the ratio of water and salt intake may be different, in which case it is advisable to seek the advice of a specialist in order to prevent complications and preserve health.

Treatments and prevention

Treatment:

• Take drugs that prevent nausea and relieve weakness.
• Stick to your diet. Avoid fatty, heavy and spicy foods.
• Drink plenty of water.
• Get enough rest and sleep at least 7-8 hours a night.
• Increase your level of physical activity. Exercise regularly.

Prevention:

• Avoid stressful situations and difficult life periods.
