Lack of sleep makes you less alert and more irritable at home and work. Sleep is often viewed as expendable and something you can catch up on anytime. But sleeplessness adds up, and it's difficult to catch up when you continue to accrue a sleep debt that puts you further behind as you try to keep up with life's demands. Good sleep habits can play a role in how well your body and mind rest. Sleep allows the body to reenergize organs and muscles and the mind to consolidate learning into memory.
