Sunlight exposure is important for maintaining adequate levels of Vitamin D, which is essential for various bodily functions, including testosterone production and cell-to-cell communication. Getting at least 10 minutes of sunlight daily, a few times a week, can help optimize your Vitamin D levels. If sunlight is scarce in your area, you can consider visiting a tanning salon that uses UV spectrum rays. Remember to prioritize your safety and consult with a healthcare professional.
