With so many women going to school or work full-time, the evening may be the only time we can fit in our sweat sessions. Evening workouts are a great way to release stress from a busy day, and exercise can improve the quality of your sleep, but if you exercise too close to bedtime, you may end up tossing and turning and counting sheep for hours. If this sounds familiar, shift your workouts to a slightly earlier time. According to Women's Health, working out late can cause sleep problems since "it can take three to four hours for your body to cool itself afterward. When your core body temperature is too high and your heart rate is too fast, it can keep you awake."
The solution? Finish your workout at least three hours before you hit the hay. An even better solution is to work out in the morning — research shows that morning exercisers burn more calories. If a.m. workouts aren't possible, schedule your gym time for the afternoon. You'll feel the energy-boosting effects for hours, and be able to fall asleep soon after your head hits the pillow.
