Sleep deprivation can lead to serious health conditions such as heart disease, heart attack, heart failure, irregular heartbeat, stroke, and diabetes. As sleep also plays an important role in our ability to think, a disruption in your sleeping pattern can also significantly impair attention and alertness, concentration, and the ability to reason and problem-solve – affecting work and/or school performance. In addition, it can also have a negative effect on personal relationships by lowering libidos and causing those around us to also develop a low quality of sleep. Sleep deprivation can also cause skin problems. If you are not getting the recommended amount of sleep each night, a protein called collagen breaks down which makes your skin appear dull or lackluster as a result, as well as developing the appearance of fine lines and dark circles.
