Sleep Science
We spend a third of our lives sleeping. Why and how we sleep is what sleep science is all about. A good way to figure out why we sleep is looking at what would happen if we would stop sleeping. Not getting enough sleep would have serious consequences on our brains’ ability to function. Even more than the usual grumpiness, grogginess, irritability, and forgetfulness after pulling an all-nighter. With continuous lack of sleep, language, memory, and even sense of time start to be severely affected. In contrast, as little as seventeen hours of continued wakefulness leads to a decrease in performance comparable to an alcohol level of 0.05%. In addition, Sleep science shows that sleep-deprived humans also have trouble responding to rapidly changing situations and making rational judgments. Consequently, the reason we sleep is that our body and mind need it to function properly.
