Sleep is a very important human need. It is even more so for our children and teenagers. They need to be able to rest and recharge their batteries at night. Sleep has a huge impact on the brain, making it less efficient in terms of cognitive processes. Sleep deprivation can cause depression, anxiety, and other mental illnesses as well as lower productivity levels. The reason why sleep is important is that it helps the body to repair itself after a hard day's work or after an intense workout. Sleep also helps the body to adapt to new situations or environments, which means that people who are constantly working in different places will have their bodies adapted to them over time, thus improving their performance in any given situation.
