Ten Things You Probably Didn't Know About Your Body and Health
1. Rinsing your nose with salt water can help keep you healthy and ward off allergy symptoms.
2. Dogs can smell cancer and low blood sugar. A study showed that it is possible to train dogs to identify, based on breath samples, which patients had lung and breast cancer. For diabetics, the dogs can smell ketones in urine and on the breath when blood sugars are high. Dogs can pick up on other smells that humans can't when glucose levels drop.
3. Researchers found that people who pass through an entryway near the kitchen tend to eat 15 percent more than those who use the front door.
4. You're more likely to have a heart attack on a Monday, or up to three days after you've been diagnosed with the flu or a respiratory tract infection.
5. You can't get a tan from your computer screen. The Computer Tan Web site was created as a hoax to raise awareness about skin cancer.
6. Obese people spend approximately $485 more on clothing, $828 on extra plane seats, and $36 more on gas each year than their thinner counterparts. An overweight driver burns about 18 additional gallons of gas a year.
7. Smokers are four times as likely to report feeling unrested after a night's sleep than nonsmokers. Smokers often experience withdrawal symptoms at night, thus causing periods of restlessness and waking.
8. Eating fruits and vegetables may help your body make its own aspirin. Benzoic acid, a natural substance in fruits and vegetables, causes people to produce their own salicylic acid, the key component that gives aspirin its anti-inflammatory and pain-relieving properties.
9. A 20-minute nap can improve your overall alertness, boost your mood, and increase productivity. In addition, your heart may reap benefits from napping -- a six-year study found that that men who took naps at least three times a week had a 37 percent lower risk of heart-related death.
10. Your kitchen sink is dirtier than your bathroom. There are typically more than 500,000 bacteria per square inch in its drain, and the faucet, basin, and sponge are crawling with germs as well.
