The right amount of stress can actually help you. It keeps you alert and full of energy. Too much, though, can harm your quality of life and keep you awake at night.
Even though you might feel frazzled, you may try to get by on less sleep than you need. But better sleep can help you fight infections, boost your metabolism, and cut your chances of getting diseases like high blood pressure and diabetes. Controlling your stress can improve your rest. It's a win-win.
