Best SAD Lamps for Treating Seasonal Affective Disorder

A sun lamp, or a light therapy lamp, has been found to be an effective treatment for people having seasonal affective disorder (SAD). Seasonal affective disorder is now clinically known major depressive disorder with seasonal patterns. This type of depression causes persistent sadness or depression when the seasons change, especially in the fall and winter months, when the days become shorter, and there is less exposure to sunlight. Medication, therapy, and counseling are all effective treatments for seasonal affective disorder, and SAD lamps or sun lamps are one treatment option that many people use to reduce the symptoms and provide relief. Here are some of the best SAD lamps for treating seasonal affective disorder.

What is a SAD Lamp?

A SAD lamp, also known as a sun lamp or light therapy lamp, is an effective form of treatment for seasonal affective disorder (SAD). Seasonal affective disorder is a type of major depressive disorder with seasonal patterns, and it is associated with the lack of sunlight that occurs as the days become shorter in the fall and winter months.(1, 2, 3, 4) Since people take in less natural light during this time as compared to the sunnier and brighter summer season, they experience a fall in the levels of serotonin, which is the ‘happiness’ hormone that occurs naturally in our bodies. This makes some people feel more depressed and exhausted. SAD lamps or light therapy lamps help people feel better by providing light that mimics natural sunlight.(5, 6)

SAD lamps can also help people with general depression. Since people with other forms of depression also experience low serotonin levels, such people can also experience alleviation of their symptoms from using light therapy lamps.(7, 8, 9) SAD lamps are also known to help people with sleeping disorders like insomnia, jet laugh, or just drowsiness caused by a change in working shift schedules. This is because light therapy helps regulate the body’s natural circadian rhythm, which is your natural sleep and wake cycle. SAD lamps help fight against fatigue and restlessness created when the body’s circadian rhythm is disrupted (10, 11, 12)

How To Choose The Best SAD Lamp?

There are many types of sun lamps and lightboxes available in the market and online that are frequently marketed as SAD or light therapy lamps. However, not all of these lamps are appropriate for use or even effective for seasonal affective disorder or other disorders.

Since SAD lamps are not regulated by the US Food and Drug Administration (FDA), which is why it is so important to ensure that you buy a SAD lamp that provides sufficient light and has been specifically designed for the treatment of seasonal affective disorder.

Some of the features you should look for while choosing a SAD lamp include:

Specifications: An effective SAD lamp should generate 10,000 lux of cool-white fluorescent light. A lux is the measurement of light intensity along with area. Having an output of 10,000 lux means that the lamp generates 20 times more than the light output of most indoor lighting. Lamps with less lux need to be used more frequently than the higher lux ones. You should get a glare-free SAD lamp or at least a lamp that can be positioned at a downward angle so that it eliminates or reduces eye glare.

Safety Considerations: You should not buy a light therapy box that has been designed for the treatment of skin conditions. These lamps are not intended to treat mood disorders and depression. So these won’t be effective in treating seasonal affective disorder. Make sure that the lamp is able to filter out ultraviolet light, and there is a label on it that says UV-free. UV light causes damage to your skin and eyes.

Size: The SAD lamp you buy should have a light surface area of approximately 12 by 15 inches. The larger the surface area, the higher will be the lux of the lamp. Larger lamps also allow you the freedom of moving around more, so you can sit farther away from the lamp without compromising the effectiveness of the light therapy. Smaller SAD lamps are not considered to be as effective as the larger ones, and you may need to use them more frequently and for longer time periods. However, you may also wish to buy a second, smaller lamp if you travel a lot and would like to carry the lamp with you. If your doctor has prescribed a SAD lamp for you, they will also provide individualized usage guidelines for you.

Personal Needs and Style: You should also keep in mind what activity you are most likely to be doing when you use the lamp. You should buy a lamp that will let you easily carry out this activity. For example, lightboxes are known to help with jet lag. (13, 14) So, if you are a frequent traveler, you should ideally buy a small portable lamp.

Seasonal affective disorder, or major depressive disorder with seasonal pattern, is a condition caused by a change of seasons, particularly in the fall and winter months when the amount of sunlight is less. Women and young adults are most affected by this type of depression. Using a SAD lamp, or a light therapy lamp, or a lightbox is an effective form of treatment for seasonal affective disorder. A SAD lamp can help provide relief from your symptoms and also boost your mood. SAD lamps are effective for treating this type of depression when used either as a solo treatment or even when combined with other types of treatment like therapy and medications. However, it is always advisable to use these lamps after consulting your doctor.
