Four Body Hacks: Easier Pills, Quick Cooling, Confidence, and Coffee Naps

Tilt your head forward instead of backward once the pill is in your mouth. It should float to the back of your throat, where it's easier to swallow.

Run cool water over a pulse point, like your wrist or the back of your knee (or wrap one in a wet bandana), to bring your whole body's temperature down in a flash.

Research shows confidence can work backward from posture: standing with feet spread and hands on your hips stimulates testosterone, which can make you feel more confident, not just look it.

Caffeine blocks the same brain receptors that make you feel drowsy, while sleep clears those receptors out. Drink a cup of coffee, then nap for about 20 minutes. You wake up just as the caffeine kicks in, on a brain that's already cleared out some of its natural sleepiness. A longer nap works against you, since deeper sleep stages cut the effect.
