Does light therapy help in the production of vitamin D?

To answer the question above briefly: no, light therapy does not aid in the production of vitamin D. We explain below how your body actually produces vitamin D and how you can use a daylight lamp.

How do you produce vitamin D?

Your body produces vitamin D through, among other things, the UVB radiation from the sun. This radiation does not come from a daylight lamp. There are tanning beds that emit UVB radiation, but that is not very good for your skin. A single tanning session exposes your skin to as much UV radiation as a day at the beach (!), and research has shown that people who use tanning beds have a higher risk of skin cancer (source: kwf). Therefore, it might be advisable to take vitamin D supplements during the darker months. This ensures your body receives enough vitamin D in a safe manner.

Can light therapy help with the autumn/winter blues?

The daylight lamp is becoming increasingly popular once the darker days begin. It is true that daylight affects your circadian rhythm and, consequently, many bodily processes. Do you feel not quite yourself in autumn or winter? Always consult with your healthcare provider.

When should you use the light lamp?

Do you already have a daylight lamp at home? It is best to turn it on immediately in the morning, when it is still dark outside. This best simulates the idea of natural daylight.
