Know these numbers

Here are some great numbers to remember, when it comes to your health!

The first health number: **2. **That’s the number of shot glasses’ worth of sunscreen you should slather on before heading outside. So says dermatologist Dr. Perry Robins. Studies show that repeated burns put you at serious risk for skin cancer, so you’ve gotta protect yourself! Also, wait //at least//30 minutes after applying your sunscreen before you go outside, to allow the active ingredients time to absorb into your skin.
Keeping with our "2" theme, don’t forget to reapply your sunscreen every
**2 hours**.
The next health number: **70. **As in, 70 degrees is the perfect bedroom temperature for getting maximum sleep. Why 70 degrees?Well, in order to trigger the production of sleep-inducing brain chemicals, your core body temperature needs to drop slightly at night. It usually drops by at least a degree from the temperature it is during waking hours. If your bedroom is too warm, you’ll keep waking up because your body will think it’s morning. So the Yale Center for Sleep Medicine says no matter what time of year it is, your bedroom should stay at the same temperature to ensure a restful night – and the ideal temperature is 70 degrees.
And one more health number: **500. **That’s the number of calories you’ll need to burn each day in order to lose **one pound **in a week.
Think trimming 500 calories a day is going to be too hard? Then know
this: If you take your dog for a 15-minute walk in the morning, skip your can of soda at lunch, and play 30 minutes of basketball with your buddies when you get home, you’re pretty much there.
