Nobody knows why people need sleep. Most of the time, no matter how much we’re fighting it, the body will eventually shut down to get some rest.
Many people, however, seem to believe they know why we can’t fall asleep easily and what we can do to fix that inconvenience.
Why someone is sleep deprived is usually his or her own fault. Daily habits and life style get in the way. But don’t be quick to judge because they may have been misinformed, causing a vicious cycle of bad habits leading to chronic tiredness.
