What Your Heart Thirsts for

Even mild dehydration can harm your ticker nearly as much as smoking a cigarette, a report from the University of Arkansas shows. “Dehydration makes blood more viscous, which has a negative effect on the cardiovascular system,” says study co-author Stavros Kavouras. “It may also increase levels of certain hormones that are known to harm the endothelium [a thin layer that lines all your blood vessels and helps regulate your blood flow].” Luckily, unless you stay chronically dehydrated, there’s probably no lasting damage, Stavros says. So, drink up. If you’re not taking six bathroom breaks a day, your body could use more water.

Sleep in this long and you’re likely to eat more and take 1,634 fewer steps per day than if you’d gotten out of bed earlier, new research has found. “People who wake up later logically have less time during the day to exercise,” says Kelly Baron, the study’s co-author. “They consume more fast food and less vegetables too.” You may have to work harder to eat healthy and exercise on lazy weekends. Or just curb your night owl habits if they’ve got you hitting snooze too many times.

DON’T EAT THAT!
Sorry, the five-second rule when your food drops onto the table doesn’t apply. Researchers from Rutgers University have recently debunked that popular belief. In their experiment, scientists crossed four different surfaces – stainless steel, ceramic tile, wood and carpet – with four different foods – watermelon, bread, bread and butter, and gummy candy – and found that crosscontamination can begin in less than one second.
“Transfer of bacteria from surfaces to food appears to be affected mostly by moisture,” says study author Donald Schaffner. “Bacteria don’t have legs; they move with the moisture. And the wetter the food, the higher the risk of transfer. Also, longer food-contact times usually result in the transfer of more bacteria from each surface to food.” Unsurprisingly, watermelon had the highest rate of contamination, and gummy candy the least. That said, play it safe and leave dropped food out of your mouth.

ASK THE EXPERT
“Why am I so hungry when I have my period?”
Your body needs extra food because you’re burning 100 to 300 more calories a day than usual, says Dr Diana Hoppe, an obgyn in San Diego. The reason: It takes a lot of energy to fuel the hormonal fluctuations that occur just before and during your period, and your metabolism speeds up by as much as 15 percent in response to that increased demand, she explains.
If you’re starving, eat an extra snack or a small meal. But aim for quality calories. “Load up on lean proteins, iron-rich foods and omega-3 fatty acids,” Dr Hoppe says. Try soba noodles with shrimp, or spinach salad with chicken and walnuts. According to her, the protein will fill you up, and the iron and omega-3s will help balance the hormone swings that are causing your extra appetite.
