The American Cancer Society tells us that the hot dogs, burgers, and chicken we take on our picnics should be kept at 140 degrees F or higher and that our cold food should stay chilled at 41 degrees F or colder. Real Simple magazine weighs in on a few temperature matters too.

There are the basics: Normal body temperature is 98.6 degrees F, water boils at 212 degrees, and it freezes at 32 degrees. But what's the ideal temperature for wine? Well, 45-50 degrees F for white wine and 60-65 for red. What about that relaxing bath that's calling your name? Water temp should be 96-104 degrees. Make it any hotter and you may break down your skin's protective barrier, which guards against pollution, germs, and bacteria. Who knew?

Did you know your fridge should be set between 32 and 40 degrees and your freezer should register at a big fat 0? Food will spoil faster in warmer temps, and the quality of food will change if it's too cold. What about green tea? Your water should reach 170 degrees. This is lower than what you need for black tea because green leaves burn more easily. An omelet? You want an internal temperature of 160 degrees. And when your day is coming a close and it's time for a little shut-eye, snuggle in at a nice 68 degrees. A good sleep requires your body temperature to drop by losing heat into the environment. Sticking your arms and legs outside the covers and removing your bedtime socks will help the heat escape.
