Can Heat Give You a Headache: Causes, Symptoms, Treatment, and More

Heat headaches are an unfortunate part of the summer season, given that many factors during this time of year can give you heat headaches. Changes in air pressure, humidity, temperature, and dehydration can give you a heat headache.

Headaches, heat-induced migraine, and tension headaches are all distinct yet interrelated phenomena that can occur. It is also understandable to worry about whether your symptoms are heat exhaustion or COVID-19. Though this article can help you identify potential symptoms, you should always contact a healthcare provider.

Having a headache from heat is no joke. Roughly 20% of American women and 10% of men have severe migraines and headaches at least once every three months. In general, chronic pain affects anywhere from 11% to 40% of Americans and is paired with lost productivity, lower quality of life, and healthcare costs.

Like general chronic pain, headaches are also more prevalent in adult Americans with less income and education and among populations of adult Americans with higher stress. For these groups, a headache from the sun can also intersect with other socioeconomic conditions.

What’s the Difference Between Heat Headaches, Heat-Induced Migraines, Heat Exhaustion, and Tension Headaches?

Most headaches people experience are tension headaches, which also may be called stress headaches or tension type-headaches. Pain may also be present in the neck, eyes, and face; the person experiencing the headache may also feel as if it is spreading to other parts of the body, such as the back and shoulders.

The distinction between migraines and tension headaches is important because migraines have additional neurological symptoms beyond pain, a longer duration, and are both chronic and reoccurring. Symptoms may include but not be limited to nausea and/or vomiting, sensitivity to light, and visual disturbances or auras.

Why Does the Heat Give Me a Headache?

Despite these differences in these conditions, heat can cause headaches and migraines alike. Humidity and changes in weather are both triggers for headaches and migraines. In less scientific terms, changes in moisture and heat can give you a headache.

The mechanisms of how this relates to a headache from the sun are still not entirely known. One hypothesis is that changes in sinus fluid pressure and distribution trigger changes, but this still does not account for a variety of symptoms and potential mechanisms.

Can bright light and heat cause headaches? Yes, too much or changes in light and sound can trigger both headaches and migraines. Stepping outside into a bright and loud summery environment may make enjoying traditional summer festivities difficult.

Dehydration can cause heat headaches and migraines. Sweating keeps you cool through evaporation. Heat in your body is used instead by water molecules on your skin to become gaseous.

Humidity and heat causes headaches and feels worse because there’s less room in the air for water on your body. Heat and energy are always “looking” for places where this is less of it.

Dehydration happens when the amount of moisture you’re using to keep cool outweighs the amount of water you’re ingesting. It also causes fatigue, light-headedness, and cardiac and circulatory symptoms. This is another way heat can cause headaches.

Dehydration can also lead to heat exhaustion, a precursor to heat stroke. These can be life-threatening conditions, and if you think you are experiencing them, you should seek immediate medical treatment.

Heat exhaustion occurs when the body is not taking in enough water compared to how much is being used, whereas heat stroke begins once the body hits temperatures over 104.0 °F (40.0 °C). Changes in body temperature (in both directions) can cause headaches, dizziness, confusion, and hallucinations.

How Can I Tell if I Have a Heat Headache?

There can be a big difference between what symptoms you need to receive a professional diagnosis regarding headaches and migraines and what symptoms are useful to identify for home treatment. Again, if you suspect you are suffering from heat stroke, dehydration, or other serious medical conditions, you should seek professional help.

The main symptom of both heat headaches and heat-induced migraines include pain in one’s head, eyes, neck, or temples. This may manifest as a throbbing, tightening, or pressing sensation. This is often frequently accompanied by fatigue, photosensitivity, and dehydration. For professional diagnoses of headaches and migraines, other distinctions exist related to pain duration, location, and neurological symptoms.

When Should I Seek Medical Treatment for Heat Headaches?

The following symptoms are signs that your heat headache or migraine may be escalating to heat exhaustion or heat stroke:

• dizziness or disorientation
• severe thirst and/or changes in appetite
• body temperature of over 104.0 °F
• nausea or other gastrointestinal symptoms
• clammy skin and/or loss of skin coloration

How to Get Rid of Heat Headaches

Treating heat headaches before they become more severe not only helps with pain relief but can also be life-saving and prevent costly medical care. While many forms of home remedies and cultural practices exist, the Centers for Disease Control recommend the following three points of care: getting out of direct sunlight, resting, and hydrating.

Seeking shade or shelter from the sun directly reduces the amount of heat the body is exposed to and makes it easier to recover resources and find relief. Resting and using fewer bodily resources again allows your body to devote all its resources to cool off. Most important, you also need to make sure to increase the amount of water you’re taking into account for lost resources.

Over-the-counter pain relievers such as ibuprofen and acetaminophen can also aid in providing pain relief while the underlying causes are addressed.

Applying a cloth that has been dipped in cold water to the back of the neck can provide relief from the sensation of being hot and make it easier for heat to leave the body (the heat “moves” to the wet cloth).

There is some debate as to whether antioxidants and electrolytes help rehydrate the body or the effect of such components has been exaggerated by various industries. For purposes of medical treatment, water is always the best choice.

Summary

In short, there are many ways heat can cause headaches. The best action is to stay out of the heat and remain hydrated. Many of the mechanisms behind chronic pain are still being researched, but we know for sure that weather and heat can cause headaches and migraines.

As with many conditions, swift treatment and preventative measures go a long way. Dressing in weather-appropriate attire, taking breaks from direct sunlight, and hydrating can all help prevent developing head headaches and migraines.

Finally, if you suspect you are suffering from heat stroke or heat exhaustion, you should always seek out immediate medical attention. Home remedies and treatments cannot replace proper medical care.

Though heat exhaustion or heat stroke are scary to experience, lethal or life-long consequences can be prevented by medical professionals.

Heat Headache Symptoms, Causes, and Treatments

Severe headaches and migraines are not uncommon, affecting 20 percent of women and nearly 10 percent of men living in the United States.

Headaches seem to be even more likely to happen in the summer months when temperatures are elevated. Headache frequency may rise when it’s warmer out for a number of underlying reasons, including dehydration, environmental pollution, heat exhaustion, and even heat stroke being more prevalent as temperatures rise.

Heat itself may be a trigger for headaches, although research results vary.

A heat-induced headache may feel like a dull, thudding ache around your temples or in the back of your head. Depending on the cause, a heat-induced headache may escalate to a more intensely felt internal pain.

Heat-induced migraine

Migraines affect approximately 18 percent of women and 6 percent of men in the United States, and they’re more common in the warmer months.

A heat-induced migraine is not the same as a heat-induced headache, because the two have some differences in their symptoms. What heat-induced migraines and headaches have in common is that they’re both triggered by the way that heat affects your body.

A heat-induced headache may not be caused by hot weather itself, but by the way your body responds to heat.

Weather-related triggers of headache and migraine include:

• sun glare
• high humidity
• bright light
• sudden dips in barometric pressure

Heat-induced headaches can also be caused by dehydration. When you’re exposed to higher temperatures, your body needs more water to make up for what’s being lost as your body sweats. Dehydration can trigger both a headache and a migraine.

Weather conditions can also cause changes in your serotonin levels. These hormonal fluctuations are a common migraine trigger, but they can cause a headache, too.

Prolonged exposure to high temperatures also puts you at risk for heat exhaustion, one of the stages of heat stroke.

Headache is a symptom of heat exhaustion. Any time you’re exposed to high temperatures or spend a long time outside under the hot sun and get a headache afterward, you should know that heat stroke is a possibility.

Symptoms of a heat-induced headache can vary according to the circumstance. If your headache is triggered by heat exhaustion, you will have heat exhaustion symptoms in addition to your head pain.

Heat exhaustion symptoms include:

• dizziness
• muscle cramps or tightness
• nausea
• fainting
• extreme thirst that won’t subside

Medical emergency

Heat exhaustion is a medical emergency and can lead to heat stroke if it’s not treated. Seek immediate medical help.

If your headache or migraine is related to heat exposure, but not connected to heat exhaustion, your symptoms may include:

• a throbbing, dull sensation in your head
• fatigue
• sensitivity to light
• dehydration

If heat tends to trigger your headache or migraine, you can be proactive about prevention.

If possible, limit your time outside on hot days, and protect your eyes with sunglasses and a hat with a brim when you venture out. Exercise indoors in an air-conditioned environment if you’re able to do so.

Drink extra water as temperatures start to rise, and consider drinking sports drinks to replace your electrolytes.

If you already have a headache, consider home remedies like:

• lavender or peppermint essential oils
• cold compresses
• iced herbal teas
• herbs like feverfew or willow’s bark

Over-the-counter acetaminophen (Tylenol) and ibuprofen (Advil) can also be used as needed for pain relief.

Mild headaches and migraines caused by dehydration or changes in the weather will usually go away on their own within one to three hours. But there are times when a heat-induced headache is a sign you need emergency care.

Seek medical help right away if you have a heat-induced headache with any of the following symptoms:

• nausea and vomiting
• high fever (103.5 degrees or higher)
• a sudden spike in pain levels or intense pain in your head
• slurred speech, confusion, or disorientation
• pale or clammy skin
• extreme thirst or lack of appetite

If you don’t have emergency symptoms, but are getting headaches or migraines more than twice a week over a span of three months, schedule an appointment to speak with a doctor.

If you typically experience migraines, you know what to expect from your body when you have one. If your migraine symptoms last for more than 7 hours, or if you experience symptoms that aren’t typical for your migraine, call a doctor.

While more research is needed to understand exactly how heat is connected to headaches and migraines, we do know that dehydration, mineral loss, sun glare, and heat exhaustion can all cause headaches and migraines.

Be aware of the way that the higher temperatures can affect your body, and try to plan accordingly to prevent heat-induced headaches.

If you experience a headache in addition to symptoms of heat exhaustion, seek emergency medical care.

Neurologist Kudryavtseva told what to do if your head hurts in the heat

Summer is like this, they wait for it for months, and then they suffer and suffer, complaining about stuffiness, stinging insects, high humidity and exhausting scorching sun.

Hot days often become a real test for people with chronic diseases, hypertensive patients and heart patients. High air temperature can also provoke an increase in migraines in those who suffer from regular headaches, and even a deterioration in well-being in perfectly healthy people. Why is this happening?

Heat headache triggers

– People who suffer from migraine-type headache attacks may experience an exacerbation in the summer. One of the triggers of migraine headaches – bright sunlight, , neurologist Anna Kudryavtseva told Doctor Peter. “By passing through the retina and optic nerve, it can activate sensory nerve cells in the brain. Therefore, with prolonged exposure to the sun, especially between 11 am and 5 pm, a person may experience intense headaches.

The second trigger for heat headaches is dehydration.

– In summer, on hot days, the body loses a lot of fluid through the skin, so it is important to compensate for this loss and drink enough water, explains the doctor. – Under normal conditions, the norm is 25-30 ml per 1 kg of normal weight, but in hot weather you need to drink more.

Another trigger for headaches can be eating very cold food ice cream or ice-cold drinks, the expert adds.

– In this case, the trigeminal nerve transmits signals from the dilated vessels of the palate to the brain, which causes a sudden headache, explains Anna Kudryavtseva.

• Be sure to keep a headache diary to identify your own triggers and gradually get rid of them.

• Wear sunglasses with UV protection.

• Avoid prolonged exposure to the sun, especially during the hottest part of the day.

• If you like to sunbathe, do it under an awning.

• Do not forget about drinking regimen: a bottle of water should always be with you.

We sleep during the day and don’t skip breakfast

– People who live in hot countries sleep during the day. Therefore, if there is an opportunity to sleep in hot weather, you should definitely use it, – advises Professor Mikhail Kutushov. – Also, people suffering from migraines need to eat right – choose less fried and smoked, reduce daily doses of caffeine, chocolate and cheese.

In no case should you skip breakfast and dinner – otherwise metabolic processes are disturbed.

– Do not drink much and often alcohol, the doctor recommends. – It has been established that with migraine, the number of platelets, which are in serotonin, is reduced. The body tries to compensate for this fact, more serotonin is pushed into the brain, respectively, an increase in the number of platelets increases the risk of thrombosis.

What to do if you have a headache in the heat

– In addition to a headache on a hot day, you may experience nausea or vomiting, and even visual symptoms – blurred vision or blind spots (so-called aura), in addition – sensitivity to sound or light. Facing them you can take an anesthetic, and also lie down in a quiet dark room – this will help relieve the severity of the attack, – advises doctor Anna Kudryavtseva.

Earlier, a neurologist Valery Chernenko warned that only paracetamol can be prescribed to oneself without a doctor, it is available in all countries without a prescription, but we must remember that this drug “beats” the liver.

If there is no way to see a doctor, then non-steroidal anti-inflammatory drugs will help with a headache – they work on approximately the same principle.

– You need to drink them strictly after meals and only when it hurts , recommends Valery Chernenko. – They take such drugs 1-2 times a day, but the time limit is a week. If it doesn’t get easier, it means something serious, there’s no point in continuing to take pills, you need to see a doctor who will find out what the problem is.

Headaches in hot weather can be caused by high air temperature, eating ice cream or pieces of ice, and fluctuations in blood pressure. This is reported by the website “Arguments and Facts”.

Neurologist-vegetologist Elena Belenko noted that in the heat the body tries to cool down and releases sweat on the surface of the skin. Moreover, if there is no replenishment of the secreted fluid, then the body is in conditions of deficiency. Because of this, a spasm of the vessels of the head occurs.

The doctor recommended to compensate for the loss of fluid. Belenko explained that under normal conditions, the norm for the drinking regime is 25-30 milliliters per kilogram of body weight. In the heat, the specialist advised to increase the amount of water you drink, if there are no contraindications.

The neurologist stressed that headaches can also be caused by eating ice cream, cold liquids or pieces of ice. This pain is called sphenopalatine ganglioneuralgia.

“First, the body feels a sudden intense cold in the mouth or throat, then it tries to react and warm up these chilled areas. The blood vessels throughout the head dilate, allowing extra blood to flow into this area for warmth. This rapid change in the size of the blood vessels causes sudden pain.” – said Belenko.

In this case, the neurologist recommended that she stop eating or drinking cold water and replace it with liquid at room temperature. The person may also press their tongue or thumb against the palate to transfer heat and warm the frozen area.

Belenko said that a headache can appear due to fluctuations in blood pressure. At the same time, in the heat there can be both a decrease and an increase in pressure.

“Such reactions will occur if the autonomic nervous system cannot turn on adaptation, adjustment to the changed environmental conditions,” the specialist said.

The neurologist advised me to move to a cool room, put a special compress on my forehead and drink some water. In the event of a decrease in pressure, it is worth putting your feet on a pillow so that they are higher than your head. With an increase, it is worth taking the usual medicine and consulting a doctor.

People with migraines may have more frequent attacks due to dehydration, temperature changes, hot weather and bright sunlight. In the summer, Belenko recommended taking care of yourself and not enduring a headache, but to see a doctor.
