People most commonly use sun lamps to treat a form of depression called seasonal affective disorder (SAD) or to help their body make vitamin D. However, choosing the right sun lamp can be challenging.

Doctors sometimes refer to the use of a sun lamp as “light therapy.” People with SAD are the most likely to use sun lamps, also called light boxes.

SAD is a type of depression that tends to happen in the late fall and winter. Most people who experience it find that it either goes away or is less severe in spring and summer.

People with vitamin D deficiency may also use a sun lamp. Vitamin D helps the nervous system, muscles, and immune system work properly. It also helps the body absorb the calcium that it needs to keep the bones healthy.

Most people will get all of the vitamin D that they need from their diet and the sun. However, individuals who do not get enough exposure to sunlight or have a health condition that stops their body from absorbing the vitamins in their food might develop a vitamin D deficiency. In children, this can lead to rickets. Adults can develop muscle weakness and pain in the bones.

Sometimes, people also use sun lamps to help with sleep disorders or depression.

Sun lamps may help people with a vitamin D deficiency, a sleep disorder, or depression.

People need exposure to sunlight for many reasons. It affects the body’s natural daily cycles, or circadian rhythms. These govern how people feel, when they go to sleep, and when they wake up.

Sunlight helps the brain make the hormones that the body needs to function. Examples are serotonin, which plays a role in mood, and melatonin, which helps with sleep patterns. The skin also uses sunlight to make vitamin D.

Sun lamps or light boxes work by imitating sunlight. Doctors might recommend, for example, that people with SAD sit by a light box that provides 10,000 lux for 30 minutes a day as soon as possible after waking up.

There is some evidence to support the benefits of light therapy, but scientists are not yet sure whether it works. Also, it is not suitable for everyone. People with light sensitivity, bipolar disorder, diabetes, or eye conditions should avoid it.

Experts advise people who wish to try light therapy to use only sun lamps that emit fluorescent light with no ultraviolet (UV) wavelengths. UV light can damage the skin and lead to skin cancer.

However, for people using a sun lamp to help their skin make vitamin D, UVB light is essential. Anyone considering using a sun lamp should speak to their doctor first.

Many different sun lamps are available to buy. The best option for a person will depend on the health issue they wish to address.

Using sun lamps, which work by imitating the sun, may help some people living with SAD, vitamin D deficiency, or sleep issues.

People should be careful when using sun lamps. In most cases, they should look for products that do not use UV light, as this can damage the skin and lead to skin cancer.

When someone has a vitamin D deficiency, their skin needs UVB light to make the vitamin. However, in most cases, it is better to get vitamin D from food and natural sunlight than to use a sun lamp.

Light therapy will not work for everyone. People with light sensitivities, bipolar disorder, diabetes, or eye problems should avoid using it.

Anyone who is thinking about using a sun lamp, especially those who suspect that they have a vitamin D deficiency, should speak to a doctor first.
