5 Ways Doctors Avoid Getting Colds
One of the biggest challenges our bodies have in winter is getting enough sun exposure. When it's cold outside, it's easy to stay indoors all day, especially if you work long hours. But I've noticed that if I run short on sun, I start to feel down, so I make sure to step outside for 15 to 20 minutes every day. UV rays trigger your body to produce vitamin D; too little D has been linked to depression. Vitamin D also helps your body absorb calcium, which keeps your bones strong. On top of that, it supports your immune system and might actually lower your flu risk. I also take a vitamin D supplement of 1,000 IUs every day. If you're worried your level could be too low, ask your doctor to do a simple blood test to check.
