8 Habits for a Healthy Life

10. Don’t Sweat Your Water Intake

While water is crucial for your overall health, the good news is you don’t have to schlep a water bottle everywhere. “There’s an often-repeated standard to drink eight glasses of water daily, but it’s unclear where that came from,” says Stanley Goldfarb, M.D., professor of medicine at the University of Pennsylvania. In Goldfarb’s review of 27 studies, he found no research to support the claim that forcing down more water than you would drink normally flushes your body of toxins, improves skin tone, or helps you lose weight. “Let thirst be your guide,” says Goldfarb. “If you’re healthy, there’s no reason to drink extra water.” Also, fruits and veggies, iced coffee, and tea can help you hydrate. Studies show that if you have caffeine regularly, your body adjusts, and it doesn’t have a significant diuretic effect.
