DON'T WORK OUT BEFORE BED Exercising three hours before bed will raise your physical and mental alertness, and your body temperature. “Our circadian rhythms [the natural sleep/wake cycle with which you're programmed] are governed primarily by body temperature and light,” Marks explains. “So even if you take a cold shower after exercising, it might not be enough to lower your body temperature enough for you to sleep.” Aim to get a workout in during the afternoon or evening; studies show that people are at their strongest in the afternoon.
