Sunlight helps your body produce vitamin D, which may protect against breast cancer, multiple sclerosis, and colon cancer. However, prolonged exposure can lead to deadly skin cancers.
The middle ground: It’s crucial to avoid unprotected sun exposure, regardless of its vitamin D benefits. Rely on a supplement for your daily 1,000 I.U. (international units) of vitamin D, and always wear SPF 30 on your face and body. Yes, in some cases abstinence is the surest path to moderation.
