Today’s society places sleep far below their list of priorities. People prioritize working or studying, rather than sleeping. Sleep deprivation simply means a person isn’t getting all the sleep they need. A lack of sleep could be the result of a sleep disorder, medication, or a disruption in their environment. Sleep benefits everything from learning and memory to weight management and blood pressure. Considering what sleep helps with, it makes sense missing sleep would have such adverse results. 1 2

Extra Hungry

You’ll have an appetite to eat more salty and sweet foods than usual. Ghrelin, a hormone that signals your brain that it’s time to eat, will be at higher levels. In contrast, the hormone leptin, which tells your brain when you ate enough, will be present at lower levels. 3

Weaker Immunity

While asleep, your immune system will be producing cytokines. Cytokines help your body fight infections and stress. However, the total amount of cytokines produced will be lower when sleep-deprived. To make matters worse, cells and antibodies that also help with infections will also be reduced. 4

Unbalanced Mood

The amygdala is a part of the brain that’s responsible for emotional reactions. This part of the brain is regulated by the prefrontal cortex, which manages emotions and talks directly with the amygdala. The communication between these parts of the brain is ruined by lack of sleep. Because your emotions won’t be balanced, you’ll have a big reaction to small problems. 5
