One of the keys to a better quality of life begins with sleep. It is just as important as eating healthy and exercising. When sleep is not happening, it adversely affects the body. Here are the surprising ways that sleep deprivation impacts your body.
There is a heavy correlation of reduced sleep and increased irritability and moodiness. At its worst, lack of sleep can lead to anxiety, depression or other mental illnesses. If these conditions already exist then insufficient sleep makes it worse. Sleep allows the body to reset and refresh itself to handle the challenges of the coming day.
Learning ability -
Cognitive functions decrease as sleep decreases. Recent study's have shown that students that sleep more have a higher GPA.
Students that sacrifice sleep usually have a lower GPA. This most likely has to do with sleep's role in the memory process and storing the information we acquired during the day.
Sleep is our body's way of repairing itself at night and inadequate sleep is linked to a variety of increased health risks, including:
- A weakened immune system
- Increased risk for depression and mental illness
- Increased risk for stroke, high blood pressure, heart disease, and asthma attacks
- Increased risk for untreated sleep disorders like insomnia, sleep apnea, and narco-lepsy
One of the most frightening consequences of sleep deprivation is accidents, which can lead to serious injury and even death. One type of accident is grabbing headlines more frequently now, drowsy driving, which is on the rise as the sleep deprivation epidemic continues.
In fact, the U. S. National Highway Traffic Safety Administration (NHTSA) reports that drowsy driving is related to at least 100,000 motor-vehicle crashes and more than 1,500 deaths per year.
Impaired Judgement -
Lack of sleep impacts our ability to make good decisions.
When our body is not getting the sleep it needs and feels fatigued, it tends to crave sugary, high fat and high carb foods that can lead to weight gain. Also, missing those deep sleep hours when the body repairs itself has been linked to premature aging of the skin.
