The Importance of Sleep
Humans can last longer without food than sleep. While you may feel more prepared to stay up all night partying than to stop eating, the feeling will be relatively short-lived. Provided there is water, the average human can survive one to two months without food depending on their body fat and other factors.
However, sleep-deprived people begin to experience radical personality and psychological changes after only a few days without sleep. The longest recorded time that a person has ever gone without sleep was 11 days, at the end of the experiment waking up, but stumbling over words, hallucinating and often forgetting what he was doing.
Adequate sleep is essential for optimal production of Human Growth Hormone (HGH) which repairs and enhances muscles and Lack of sleep suppresses the immune system, which can weaken academic or athletic performance, especially during stressful finals or competitions.
Lack of sleep causes an increase in ghrelin and a decrease in the hormone leptin which makes the body feel hungry and prevents the body from feeling full even though you have enough food intake. It also contributes to obesity.
