What Are Sunlight Desk Lamps?

A sun lamp, also called a SAD (Seasonal Affective Disorder) lamp, light therapy, box happy light, or natural light lamp, is a unique light designed to mimic natural light.

Light therapy, also called bright light therapy, is an effective treatment for:

  • seasonal affective disorder
  • depression
  • lack of vitamin D exposure
  • and various skin ailments.

Seasonal affective disorder is a specific type of depression during the fall and winter months when the days get shorter. We spend more time indoors and don’t get enough sunlight.

The light emitted by sun lamps helps to increase serotonin and melatonin levels in the body.

These two chemicals help control your sleep and wake cycle as well as reduce anxiety and improve mood. Low levels of serotonin are also linked to depression. 

Why Might You Need A Sunlight Lamp?

During the summer months, there are plenty of daylight hours to absorb enough vitamin D. Still, during the winter months, especially in much of North America, it is virtually impossible to get enough Vitamin D from the sun alone.

Vitamin D also referred to as the “sunshine” vitamin, is thought to protect against various diseases, including:

  • osteoporosis
  • heart disease
  • cancers of the colon, breast, and prostate.

Also, sunlight has other hidden benefits like protecting against depression, sleeping difficulties, and regulating body nutrients essential for bone health.

2010 study found the following:

  • 42% of the US population is vitamin D deficient
  • 40% of children exhibited higher but still insufficient levels of vitamin D

Some populations, such as people over 65 and premenopausal women, have even higher deficiency levels.

Different groups of people need different amounts of sun exposure or vitamin D to stay healthy.

For example, infants only need to consume 400 IU(international units) per day, whereas those over the age of 70 need around 800 IU.

The amount of sunlight one needs to absorb to accomplish this varies depending on age and skin type.

For example, during the summer months around noon in Miami, Florida, with skin type III (someone who tans well but sometimes burns) would need to spend approximately six minutes in the sun to synthesize 1000 IU of vitamin D. During the winter months, fifteen minutes would be required.

The further north one goes, the more challenging it may be to get sufficient vitamin D from the sun.

A person in Boston with the same skin type during the winter requires over an hour.

It is virtually impossible for some skin types to safely synthesize enough vitamin D from the sun alone.

For those who are not exposed to sufficient sunlight based on where they live or the environment in which they work, a sunlight lamp is necessary. It is also a safe means for increasing essential sun exposure.

Remember to always consult your doctor before use!

Don’t use sunlight lamps if you have the following:

  • existing skin cancers
  • lupus
  • diabetes
  • connective tissue damage, etc.

How Do Sunlight Lamps Help Your Circadian Rhythm?

How does the circadian rhythm affect body

Bright light therapy is an effective treatment for certain sleep-wake disturbances, including insomnia.

Certain sleep disorders, jet lag, and shift work done by hospital staff can upset your circadian rhythm.

This is the “internal clock” that helps you be alert during daytime hours and sleep at night.

When your circadian rhythms are disrupted, it can cause insomnia and extreme fatigue. It can also interfere with essential body functions that depend on the sleep-wake cycle, such as digestion, certain brain functions, and various healing types.

Exposure to artificial light from a sunlight lamp during certain times of the day can help realign your circadian rhythms and improve your sleep-wake cycle.

How to Choose and Properly Use A Sunlight Desk Lamp

  1. To ensure you get the best results from a sunlight desk lamp, the light needs to enter your eyes indirectly. This means your eyes should be open, but just as with regular sunlight, you should avoid looking directly at the light.
  2. According to the Cleveland Clinic, the best time to use a sunlight lamp for light therapy is in the morning.
  3. To achieve optimal therapeutic effect from a sunlight lamp, it must have an intensity of 10,000 lux (10,000 lumens per sq foot). That is 9,900 more lux than the average household light. Sunlight lamps are available in different intensities.
  4. It should be placed on a table or desk between 16 and 24 inches away from your face to properly use the lamp. Try to sit in front of the light for 20 to 30 minutes (or as directed by your doctor) at the same time each day.

It is essential to remember that sunlight lamps filter out most of the ultraviolet light, making them safer than other lamps. Using the wrong type of lamp could damage your eyes and cause other adverse side effects.

Frequently Asked Questions

Do sunlight lamps work?

Sunlamps positively impact the body’s regulation of melatonin, a hormone that helps control the sleep-wake cycle. Besides, they also help to regulate mood by affecting serotonin levels in the body.

Many believe that bright light therapy is now considered a first-line treatment for SAD.

Do sunlamps give you vitamin D?

Sunlamps do not necessarily “give” your body vitamin D.

The lamps emit lighting similar to that of natural sunlight, thus encouraging the skin to produce vitamin D. This is especially beneficial during winter months when natural sunlight is unable to produce enough vitamin D to meet the body’s needs. 

What does Light therapy do for the skin?

When used consistently, over time, the LED lights used in sunlight therapy lamps are thought to penetrate the skin at varying depths, resulting in various skin reactions.

These reactions can include fighting acne-causing bacteria, pumping the skin, and reducing wrinkles. This is possible as the skin uses light as a source of energy to repair and rejuvenate damaged cells. 

How many hours of light should I get from the sunlight lamp?

You should sit in front of a sunlamp for 20 to 30 minutes each day around the same time. This time frame is considered safe and standard for most sunlamp use.

However, you should not exceed the time recommended by the manufacturer or your primary care provider.

Before using a sunlamp or similar product, you should always contact your medical provider to ensure that the item is right for you to use.

What kind of bulbs are used in a sunlight lamp?

The bulbs used in sunlight lamps are also known as full-spectrum light bulbs.

They are specifically designed LED light bulbs that mimic sunlight, similar to the solar spectrum’s visible section. In other words, they produce a light similar to that of natural sunlight.

Unlike some other lights, they have minimal or no amounts of ultraviolet or infrared rays, which allows them to imitate the sunlight spectrum more precisely.

Traditional household bulbs are not safe to use in sunlight lamps.
