The Importance of Sunlight Exposure for Hormonal Health

Sunlight exposure not only helps activate the P53 pathway in keratinocytes, but it also increases testosterone and estrogen levels. People with paler skin and those from countries with less UVB light exposure had greater increases in testosterone compared to those who already had a lot of UVB exposure.

A study found that exposure to UVB light from the sun can increase testosterone, beta estradiol, and progesterone in both men and women, with the greatest increases seen in individuals from countries with low UV exposure.

Summary
A study found that exposure to UVB light from the sun can increase testosterone, beta estradiol, and progesterone in both men and women, with the greatest increases seen in individuals from countries with low UV exposure. The recommended protocol is to spend 30 minutes outside with minimal clothing two to three times a week.

This study found that people with paler skin and less UVB light exposure had greater increases in testosterone levels than those who already received a lot of UVB exposure.

Summary
This study found that people with paler skin and less UVB light exposure had greater increases in testosterone levels than those who already received a lot of UVB exposure. People with darker skin require more vitamin D3 and sunlight exposure to activate that D3 pathway compared to paler skin individuals.

Sunlight exposure on the skin activates the P53 pathway in keratinocytes, which is required for increases in ovarian and testicular size, testosterone and estrogen increases, and other physiological changes.

Summary
Sunlight exposure on the skin activates the P53 pathway in keratinocytes, which is required for increases in ovarian and testicular size, testosterone and estrogen increases, and other physiological changes. Not only is it important to get sunlight exposure throughout the day to our eyes, but also UVB sunlight exposure onto our skin to activate the P53 pathway for hormonal benefits.

Getting sunlight exposure during the winter months and still getting it in the summer, without damaging the skin, can increase testosterone and estrogen levels and improve mood, feelings of passion and the output of particular hormones and neurochemicals in the body.
