20 Things You Probably Didn't Know About Your Body and Health - Part 2

16. Regular exercise can lower a woman's cancer risk - but only if she's getting enough sleep. The National Cancer Institute followed 5,968 women for almost 10 years, during which 604 of them developed some form of cancer. Women in the top half of physical activity levels showed an approximate 20 percent reduction in cancer risk compared to those who exercised less. For a segment of those women, sleeping less than seven hours per night had a decreased benefit to exercise. Their cancer risk was greater than those who exercised but slept more - but still lower than those
who exercised the least.

18. Walking against the wind, in the water, or while wearing a backpack burns about 50 more calories per hour than walking with no resistance. People who wear pedometers
