Why is sunlight so Beneficial?
Sunlight includes orange and red light with 600-700 nm wavelengths.
The benefits of red and orange light have been well established. This type of light supports cellular energy production and mitochondrial function.
According to Dr. Ray Peat getting plenty of sunlight is beneficial to your whole health. Especially the function of the endocrine system, meaning the hormone producing glands including the thyroid gland.
Is UV light dangerous?
Sunlight also contain potential damaging blue and UV light. It is very important to avoid sunburn and it can be advisable to avoid the strong sun at midday and instead enjoy the sun in the afternoon.
The UV part of sunlight does contributes to vitamin D synthesis in the skin. However, the older we get the less effective our vitamin D synthesis becomes, and we therefore always recommend using a vitamin D supplement. You can learn much more about the importance of vitamin D in this blog post.
Why Darkness creates sickness?
Exposure to long periods of darkness can lead to many symptoms including fatigue, depression, stress symptoms, premenstrual syndrome, thyroid issues, and other hormonal imbalances.
Darkness increases the stress hormone cortisol, damages mitochondria, and decreases the synthesis of the body’s natural protective hormones including progesterone and pregnenolone. These hormones are part of the body’s natural anti-aging and anti-stress system.
Living in a cloudy and dark environment is, therefore, harmful to good health and getting enough sunlight every day is important.
In the winter or in northern cloudy weather, where sunlight is inadequate, using the right type light therapy lamps is an advantage.
Benefits Of Light Therapy
There are many light therapies lamps on the market, some are more useful than others.
According to Dr. Ray Peat, a good light therapy lamp provides light in the red and orange spectrum, these wavelengths are from 600-700 nm. Shorter wavelengths, such as blue light is harmful to cellular energy production, and the longer infrared wavelengths are according without much benefit.
In Module 15 of my hypothyroid treatment program, you can learn more about the benefits of the right type of light therapy. You will get specific information on which types of lamps are recommended by Dr. Ray Peat and specific lamps are recommended.
