Seasonal affective disorder (SAD), now known clinically as major depressive disorder with seasonal patterns, is a condition that causes sadness or depression when the seasons change.

It most typically occurs during the fall and winter, when days become short and exposure to sunlight decreases. It’s most common in women and young adults.

Counseling, therapy, and medication may all be effective for this condition. Light boxes — also referred to as SAD lamps or light therapy lamps — are another option that can reduce symptoms and provide relief. They work by replicating natural daylight.

Symptoms of SAD

There are two types of SAD: wintertime and summertime. SAD affects people differently, but the symptoms may vary based on the type of SAD.

Symptoms of wintertime SAD include:

• daytime fatigue
• difficulty concentrating
• feelings of hopelessness
• increased irritability
• lack of interest in social activities
• lethargy
• reduced sexual interest
• unhappiness
• weight gain

Symptoms of summertime SAD include:

• agitation
• difficulty sleeping
• increased restlessness
• lack of appetite
• weight loss

In severe cases, people with SAD may experience thoughts of suicide.

Treatment options for SAD

Counseling and therapy are treatment options for both forms of SAD. Some people may also benefit from medications such as antidepressants such as fluoxetine (Prozac) and bupropion (Wellbutrin). People experiencing SAD should speak to their doctor about which medication is the best course of treatment.

Light therapy can also be used as a treatment for wintertime SAD. This involves using a specialized light box or visor for at least 30 minutes each day to mimic natural light. Light therapy should only be used under a doctor’s supervision and on approved devices. Other light-emitting sources like tanning beds, are not safe for use.

Another type of treatment is a dawn simulator which uses a time-activated light to mimic the sunrise as a way to help stimulate the body’s clock.

Adopting some healthy lifestyle habits can also help minimize SAD symptoms. This can include:

• a balanced diet with lean protein, fruits, and vegetables
• exercise
• regular sleep

Keep in mind

If you have thoughts of suicide or self-harm, call 911 or the National Suicide Prevention Lifeline at 988.

A SAD lamp uses light therapy to replicate sunlight. It can trick the body into thinking it is a warmer month and cause the body to release serotonin.

The light produced by a SAD lamp is measured in lux. A lux is a measurement of light intensity combined with area. A SAD lamp should offer a brightness of 10,000 lux. The viewing angle of a lamp should allow it to be positioned above the eyes and at a slight downward angle to minimize glare.

Typically, SAD lamps or lights should be used for 30 minutes to an hour. They can be used at any time of day, although they’re usually used first thing in the morning.

SAD lamps are not regulated by the FDA.

SAD lamps simulate sunlight, which helps trigger the brain to release serotonin, often called the feel-good hormone.

Studies show that using light therapy during periods when daylight hours are short can help adjust your circadian rhythm, the body’s process for regulating your sleep-wake cycle. This is beneficial for improving mood and reducing symptoms of depression.

Light therapy has become an accepted practice for alleviating SAD and other conditions such as:

• jet lag
• dementia
• circadian rhythm sleep disorders

There are many lamps and light boxes marketed as SAD or light therapy lamps. Not all of these products are effective or appropriate for this use.

The FDA doesn’t regulate SAD lamps, so it’s important to buy one that provides enough light and is designed to treat SAD.

Here are some features to look for:

Safety

• Don’t get a light box that’s designed to treat skin conditions. These devices aren’t meant to treat mood disorders and they won’t be effective.
• Make sure the lamp filters out ultraviolet (UV) light and is labeled UV-free. UV light can damage your eyes and skin.
• Follow the instructions supplied by the manufacturers.
• Use eye protection if you have existing eye issues.

Specs

• The lamp should generate 10,000 lux of cool-white, fluorescent light. An output of 10,000 lux is approximately 20 times greater than the light output generated by most indoor lighting. Lamps with less lux may need to be used more often than brighter ones.
• Opt for a glare-free lamp or a lamp that can be positioned at a downward angle that reduces or eliminates eye glare.

Size

• Look for a lamp with a light surface area of around 12 by 15 inches. The larger the surface area, the higher the lux. Larger lamps also provide you with the option of moving around more, so you can be farther away from the lamp without compromising its effectiveness.
• Smaller lamps aren’t as effective and may need to be used more often for longer sessions. That said, you may wish to purchase a second, smaller lamp if you travel a lot. Your doctor can provide individualized lamp use guidelines.

Personal style and needs

• Think about what activity you would like to do while using the lamp and purchase one that will accommodate that purpose. For example, light boxes have been shown to help with jet lag. So, if you travel frequently, you may want to choose a small, portable option.
• Lamp styles vary. You may be better off getting an attractive lamp that matches your décor so it can stay in position for use. For maximum benefit, you’ll want to use the lamp at least once daily, so having it out and easily accessible can be a plus.

• Don’t start using a SAD lamp without your doctor’s approval: This is especially important if you have a diagnosis such as bipolar disorder, glaucoma, or lupus.
• Always get the green light from your doctor if you’re taking prescription medications of any kind, including antipsychotics and antidepressants: Remember that some prescription medications and over-the-counter supplements can make your skin photosensitive, requiring an adjustment to your use of the lamp. These medications include lithium, some acne drugs, and St. John’s wort.
• Use the lamp daily: You can use it until daylight hours increase.
• Experiment with time frame: Many people benefit from as little as 20 minutes of use. Others require 60 minutes, which is typically considered the highest exposure you should get. However, be sure to follow the manufacturer’s instructions and slowly increase the amount of time spent in front of a SAD lamp. Avoid exceeding more than 60 minutes of use.
• Consider when to use it: Many experts recommend using a SAD lamp first thing in the morning. Your doctor might also recommend that you use it during the day. Keep in mind that more isn’t always better. Overuse of a SAD lamp can produce insomnia or other side effects.
• Follow manufacturer recommendations for the position: Your lamp should come with recommendations for how close you should position yourself to it. This is very important, as your distance from it will affect the lamp’s lux capacity.
• Position the lamp so that it’s providing you with downward light: This will ensure that it doesn’t shine directly into your eyes.
• Talk with your doctor about how to best stop using the lamp: It may be most appropriate for you to wean yourself off slowly. Spending time outdoors, especially in the mornings, can help this process.

Although light therapy is helpful for people who bipolar disorder, be sure to consult with a doctor before introducing it daily. A medical professional who is familiar with your physical and mental health history will be able to help you figure out if light therapy is a good option for you.

Some studies show that SAD lamps can help boost mood and alleviate symptoms of seasonal depression, but they’re not a substitute for proper mental health care. If you feel that your depression is severe or you experience any of the following symptoms, it’s time to speak with a healthcare professional. Check in with a doctor or mental health professional if:

• You feel sad and hopeless nearly every day.
• You no longer experience pleasure in hobbies or activities you used to enjoy.
• You can’t sleep or are spending too much time sleeping.
• You’re feeling irritated and annoyed nearly every day.
• Symptoms are interfering with your quality of life.
• You’re gaining or losing weight unexpectedly.

Can SAD lamps damage your skin or eyes?

UV light should be filtered out of SAD lamps, so they shouldn’t damage your eyes or skin. However, light boxes used to treat certain skin conditions do emit UV light, so you should be sure that your light box is designed to treat SAD.

Can SAD lamps increase vitamin D levels?

While some people have found that SAD lamps can increase vitamin D levels over time, there’s not enough research to confirm this. Vitamin D is produced by UV light, and most SAD lamps don’t have that.

According to the FDA, UV lights can cause damage to the skin and should be used with caution. Long-term exposure to UV rays can also cause premature aging and skin cancer. If you’re using UV lights on your skin, be sure to speak with your doctor first.

How bright are SAD lamps?

The recommended brightness for SAD lamps is typically 10,000 lux.

How long does it take a SAD lamp to start working?

The University of British Columbia found that people can start to respond to light therapy within a few days and you should see improvements within 2 weeks. Be sure to speak to your doctor if your body does not respond to a SAD lamp after 2 weeks.

Is there anyone who shouldn’t use a SAD lamp?

You should avoid using a SAD lamp if you have an increased sensitivity to light. This may be due to:

• macular degeneration
• a connective tissue disorder
• lupus

SAD can often be alleviated with proactive lifestyle changes. These include:

• going to bed early and waking up at or near dawn
• going outside for extended periods of time, especially first thing in the morning
• avoiding substances that can adversely affect your ability to sleep, such as alcohol
• eating whole, nutrient-rich foods
• exercising
• seeking out professional help from a counselor or therapist

How to find a therapist for seasonal affective disorder

SAD can bring up serious feelings of depression, so consider talking with a mental health professional.

You don’t need to have received a SAD diagnosis to seek out help, though. Even if you’re just feeling more down than usual, it’s OK to talk with a therapist or counselor.

When looking for a mental health professional, you’ll want to specifically search for someone who has experience treating SAD, major depressive disorder, or depressive episodes.

If leaving the house is too intimidating, you can check out online therapy or online psychiatry platforms, too.

Major depressive disorder with seasonal pattern, previously known as seasonal affective disorder (SAD), is a condition caused by lowered exposure to sunlight or a change of seasons. Women and young adults are most affected by this condition.

Using a SAD lamp, also known as a light box, can help alleviate symptoms, boosting your mood.

SAD lamps can be effective when used as a solo treatment or combined with other forms of treatment. Either way, always use these lamps under a doctor’s supervision.

SAD can bring up serious feelings of depression, so consider talking with a mental health professional.

You don’t need to have received a SAD diagnosis to seek out help, though. Even if you’re just feeling more down than usual, it’s OK to talk with a therapist or counselor.

When looking for a mental health professional, you’ll want to specifically search for someone who has experience treating SAD, major depressive disorder, or depressive episodes.

If leaving the house is too intimidating, you can check out online therapy or online psychiatry platforms, too.

Major depressive disorder with seasonal pattern, previously known as seasonal affective disorder (SAD), is a condition caused by lowered exposure to sunlight or a change of seasons. Women and young adults are most affected by this condition.

Using a SAD lamp, also known as a light box, can help alleviate symptoms, boosting your mood.

SAD lamps can be effective when used as a solo treatment or combined with other forms of treatment. Either way, always use these lamps under a doctor’s supervision.

Depression to the bulb: diodes imitating the flame of a candle will save you from the blues | Articles

Russian specialists have designed LEDs that are much more economical than incandescent lamps and at the same time can help to avoid depression and insomnia . Classic energy-efficient devices are bad because they shine with a cold blue light. Such illumination contributes to the development of depressive states. Innovative LEDs are similar in characteristics to a candle flame. At the same time, they are 4-5 times brighter than a computer monitor.

Solar alternative

Candles are considered the safest substitute for natural light for the human body, the radiation spectrum of which is similar to the sun at sunset or sunrise and therefore is very physiological . Employees of the joint laboratory of South Ural State University and the Institute of Organic Chemistry (IOC) of the Russian Academy of Sciences have created innovative LEDs that are similar to the characteristics of a candle flame. As Oleg Rakitin, the head of the laboratory of polysulfur-nitrogen heterocycles of the Institute of Organic Synthesis of the Russian Academy of Sciences, explained to Izvestiya, the new LED devices are not only completely safe for human physiology, but can also reduce the risk of depression.

– Currently, incandescent lamps with their continuous spectrum, due to low efficiency and short service life, are being replaced everywhere by LED and gas-discharge sources, however, their radiation is highly enriched in blue wavelengths, which poses a threat to the human eye and can cause physiological disorders in the body,” said Oleg Rakitin.

The spectrum of the luminescence composition of modern LED sources, which are widely represented on the market, differs sharply from the radiation of a flame, incandescent lamp or the sun. While they may provide a visually warm yellow tint of light, they are actually a combination of blue and ultraviolet light emitted by a semiconductor crystal, and the yellow-orange glow of a special phosphor deposited on it.

According to the developers, the new source, thanks to its innovative design, when the warm light is emitted by the crystal itself, has practically no harmful radiation in the blue region of the spectrum, and its color characteristics are similar to the flame parameters of ordinary candles.

Bad Mood Light

According to scientists, a known problem caused by blue light is a marked decrease in the concentration of melatonin in the human body. It is a hormone that regulates sleep and wake cycles, and its secretion precedes falling asleep.

— It has been proven that maintaining an optimal level of melatonin can prevent and even treat certain types of cancer — breast, prostate, colon, — said Oleg Rakitin. – The risk of such diseases greatly increases with age, and a violation of circadian rhythms can lead to an imbalance in the correct metabolism in general.

The psychophysiological effect of light from sources with an unbalanced spectrum should not be underestimated — studies show that such light can provoke irritability and even cause depressive states. And numerous works on the effects of computer and smartphone screens, which also use LEDs, even show that they can accelerate aging and cause brain diseases.

Lamp innovations

Designed LEDs do not emit harmful radiation due to the use of original organic dyes , which have never been used to create such devices before. Some were synthesized by scientists specifically for the project. It is important that the developed composition does not contain rare noble metals such as iridium and platinum (the basis of modern industrial phosphors for LED devices), which are expensive and difficult to obtain.

At the same time, the new diode is much more energy efficient than incandescent lamps, and its brightness characteristics are better. On average, a 10 x 10 cm LED panel made of new materials, under optimal conditions, provides the same level of illumination as 10-12 conventional candles, while its brightness will be 4-5 times brighter than a standard computer monitor.

As the developers explain, the devices can be used as light sources for office or other domestic premises, lighting design elements for various public spaces and for many other purposes, but will be especially useful for their use as home lamps to facilitate falling asleep and create comfortable soft lighting. Relatively simple diode fabrication technology and inexpensive raw materials will make it possible in the future to create light sources in the form of dimmable flat panels.

A bright future

Russian scientists have made a real breakthrough, says Rodion Ganopolsky, head of the Department of Modeling of Physical Processes and Systems of the Tyumen State University.

– There are two big pluses. The first is the spectrum of emitted light, which corresponds to daylight. The second is the cheapness of production. LED lamps are now the most energy efficient, but they are still very expensive, — said the scientist.

Nikolai Sturov, Head of the Department of General Medical Practice at the RUDN Medical Institute (university participating in the 5-100 project), believes that the use of new LEDs can be beneficial to health.

– Solar light radiation in acceptable doses has general strengthening properties, we are talking about the sun as such or about some specially selected components of this radiation. Even the solarium was originally proposed as a physiotherapy procedure. Our Western colleagues quite legally prescribe sun and sea rest as an essential component of the treatment of depressive conditions. Light also has psychotherapeutic properties, he explained.

However, as the specialist emphasizes, chronic and acute depression is the result of a deep malfunction in certain brain structures. In some cases, no lamps will help – it is necessary to be treated with appropriate drugs , which compensate for the deficiency of these neurotransmitters. They, in turn, are dispensed in pharmacies only by prescription.

Work on the creation of new LEDs was supported by the Russian Science Foundation (RSF) in cooperation with scientists from the Physical Institute. P.N. Lebedev Russian Academy of Sciences and the Russian Chemical-Technological University. DI. Mendeleev.
