Quality sleep is one of the most fundamental nutrients that every person needs in order to perform at their optimal. Sleep deprivation dramatically reduces human growth hormone secretion and testosterone production. Sleep deprivation also reduces insulin receptor sensitivity leading to increased susceptibility to diabetes type II. In athletes, sleep deprivation reduces glycogen synthesis in skeletal muscle and liver cells. Effective sleep recovery depends upon the period of time in which the sleep deprivation has occurred. Sleep deprivation creates a heightened stress response within the body that disrupts normal healing and tissue rejuvenation processes.


Researchers have found that a reduction of sleep to 4 hours for 2 consecutive nights decreased circulating leptin levels and increased ghrelin levels as well as self-reported hunger. Sleep deprivation also dramatically increases the risk of heart disease, cancer, and overall mortality. In a study performed by the USCD School of Medicine, regions of the brain`s prefrontal cortex displayed enhanced activity in sleep deprived individuals during simple verbal tasks. Cognitive and endocrine function is recovered more rapidly after acute total sleep deprivation than after chronic sleep restriction. Sleep deprivation increases allostatic load on the body and rapidly accelerates the aging processes.
Sleep deprivation causes a decrease in lean body tissue, an increase in fat storage and decreased immune coordination.


Coordination, balance and reaction time are also known to be reduced in chronically sleep deprived individuals. Healthy sleep cycles help to reduce allostatic load and allow individuals to adapt to life`s stressors more effectively.
