4、 understanding why drinking too much water can be dangerous to your health. Consuming more water than you need can increase your total blood volume (容量). And since your blood volume exists within a closed system, increasing your blood volume puts unnecessary stress on your heart and blood vessels (血
5、管). Your kidneys (肾) must work overtime to get rid of extra water out of your system. Your kidneys are not a pair of pipes.

17、o DThe importance of letter carriers cannot be ignoredCDust on furniture may be bad news for waistlines (腰围). But its far too early to add dusting to a weightloss plan. Dietary fats and other materials 4that make up indoor dust can send a signal to human fat cells, telling them to grow. That process
18、, in turn, might slow the bodys rate of burning energy. Such changes could add to any weight problems a person might have.“We dont know what that means to longterm health and certain diseases yet,” says Heather Stapleton, one of the studys authors. But she notes that her teams findings also raise a
19、question of whether pollutants (污染物) in dust might play some role in the growing, global problem of obesity.Stapleton and her colleagues collected dust from homes and offices. Studies found that some materials in the dust could turn on a protein (蛋白质) called PPARgamma 1. Its found in many human tiss
20、ues. Turning this protein on can cause fat cells to grow. Researchers think this protein may be involved in obesity. But a second study now finds evidence that certain fats are mostly to blame. Cooking oils may send out some of these fats into the air, where they eventually find their way into house
21、 dust. Or, the authors say, the fats might enter house dust as part of the hair or skin cells shed (脱落) by people or pets.“While the findings are amazing,” says Mitchell Lazar, another study author, “these findings need to be taken as very preliminary.” Indeed, he adds several cautions about how the
