We know the sun has many positive elements. If you wake up in the morning before the sun is out, you do want light exposure as it helps with your circadian rhythm and also your mood. Now, one of the first things to consider is when to get sun exposure. A general rule of thumb is when the UV index is below 3. That's early in the morning and later in the afternoon. You've probably heard the sun improves vitamin D production. That is correct. You can also supplement vitamin d. I take 2000 IU every day.
