The Surprising Link Between Sunlight and Blood Sugar
Yahoo Health • • health
Key Points:
- Recent studies suggest that exposure to natural sunlight during the day can improve metabolism and help regulate blood sugar levels, particularly benefiting people with Type 2 diabetes.
- A small experimental study showed that participants exposed to natural daylight had better blood sugar control compared to those under artificial lighting, marking one of the first demonstrations of sunlight’s metabolic effects.
- Large-scale research in the U.K. linked greater sunlight exposure and tanning bed use with lower blood sugar and a reduced risk of developing Type 2 diabetes, though tanning beds carry known skin cancer risks.
- Scientists believe sunlight influences metabolism primarily by strengthening the circadian system, which regulates blood sugar, body weight, and cardiovascular function, while exposure to light at night can disrupt these processes.
- Experts recommend maximizing daytime outdoor light exposure and minimizing artificial light before bedtime to support metabolic and cardiovascular health, especially during darker winter months.
