Bright Light Therapy and Vitamin D: Dispelling the Myths

Bright light therapy devices bring the mood-boosting powers of sunlight indoors; however, a common misconception is that they are also a source of vitamin D. Let’s unpack this and dispel the myth once and for all!

Bright light therapy provides an effective solution to boosting mood, energy and alertness, just light sunlight. This is particularly important when exposure to natural daylight is limited during the autumn and winter months and when in dimly lit environments. Bright light therapy devices do not, however, act as a source of vitamin D in the same way that sunlight does.

How do bright light therapy lamps work?

What many of us experience during the bright, summer months, is that sunlight naturally helps to boost mood, energy, and alertness levels. This is because sunlight has the ability to influence our body chemistry, including the levels of melatonin and serotonin in the body. When daylight hours are limited and time spent indoors increases, many people experience fatigue, sluggishness and irritability due to inadequate exposure to light. Bright light therapy products mimic natural daylight, providing a boost to alertness, mood and energy, just like sunlight, and they serve as an effective treatment for winter blues.

What is vitamin D good for and how does sunlight influence its production?

Vitamin D plays an influential role in maintaining muscle and bone health as it helps to regulate calcium and phosphate levels in the body. It also impacts mood and energy levels. In order to produce vitamin D, UVB rays from the sun interact with a protein in the skin (7-DHC) which converts into vitamin D3.

Why aren't bright light therapy lamps a source of vitamin D?

Depending on their manufacturer, bright light therapy devices produce minimal or no UV rays at all. As it is the interaction of UV rays with a protein in the skin which leads to the production of vitamin D, bright light therapy does not facilitate vitamin D production.

Should bright light therapy be combined with vitamin D supplementation?

When exposure to natural daylight is limited, the use of bright light therapy lamps with vitamin D supplementation could provide a highly effective solution to supporting your overall health and well-being. 

Bright light therapy lamps provide a much needed boost to mood, energy and concentration, and with vitamin D supplementation, you can also receive immune support.
