Aim for 6-8 Hours of Shut Eye
Men who sleep less than five hours a night show two times the risk of developing heart disease than those who get seven to eight hours. Sleep helps to regulate insulin activity, and lack of sleep causes your cells to be more resistant to insulin, which results in higher blood sugar and may contribute to weight gain and heart disease. Exhaustion is another symptom of heart disease that is often ignored in women. If you notice that you're persistently exhausted, even after sleeping well, consult your doctor.
