Sleep deprivation linked to obesity
Getting enough sleep is essential for the functions of our body. We need enough sleep for growth, memory consolidation, maturation of the nervous system and neurogenesis, and for energy homeostasis. Lack of sleep or people who are persistently sleep deprived are most likely to encounter many obstacles. One thing that many people suffer from when they are sleep deprived is becoming obese. In this period or this modern world, obesity rate is increasing significantly, but this has some connections to inadequate sleep.

Sleep disturbances leading to sleep deprivation has an increase risk for obesity, which affects one third of the population in the United States. It is known that getting 7-8 hours of undisturbed sleep is good for adults, but not everyone gets 7-8 hours of sleep. Waking up frequently at night or being unable to remain asleep at night also impacts body weight. Getting enough sleep at night is important for normal body weight, but not getting enough sleep at night will lead to becoming obese. One of the reason why this leads to obesity is sleep fragmentation. Sleep fragmentation is basically repeated, short sleep interruptions during the night. This leads to EDS excessive daytime sleepiness. Another condition is called Narcolepsy, which is a chronic sleep disorder the causes daytime drowsiness or uncontrollable daytime sleepiness. The people that have sleep fragmentation reports having short total sleep had lower physical activity and gained more weight.

So having sleep fragmentation leads to daytime sleepiness, and this can cause " Low physical activity, neurohormonal changes, altered insulin sensitivity, inflammation and altered glucose metabolism, which might perpetuate adiposity gain". So from this it can be concluded that severe sleep deprivation or sleep restrictions can cause humans to gain a lot of body weight.
