Sleep plays an important role in good health and well-being throughout your life. Getting enough quality sleep can help your brain work properly and improve your learning and problem-solving skills. A good night’s sleep also helps you pay attention, make a decision and be creative. On the other hand, ongoing sleep deficiency can link to an increase risk of some chromic health problems – heart disease, kidney disease, high blood pressure, diabetes and stroke. Sleep deficiency also affects how well you think, react, work, learn and get along with others.
