We all neglect sleep sometimes, whether for our jobs or for movie marathons, but many of us don’t fully understand the seriousness of sleep deprivation. Lack of sleep obviously decreases vitality and makes you more irritable, but sleep loss can affect much more than that. Sleep loss can severely harm your memory, health, reasoning skills, and even ability to lose weight. Here are 5 reasons to get a good night’s sleep every night.
1. Sleepiness leads to serious accidents.
Chernobyl – what some consider to be the world’s worst nuclear disaster – was caused by lack of sleep. Three Mile Island, the Exxon Oil Spill, and even the Challenger Explosion were all caused in part by lack of sleep.
Sleepiness has dire effects on people’s abilities to be safe when working with technology. Drowsiness can severely slow reaction time, which can be devastating on the road. Sleepiness is one of the leading causes of vehicle accidents, so get sleep and be safe.
2. Sleepiness impairs your cognition.
Sleep is critical for maximizing the brain’s capacity. Lack of sleep prevents thinking and learning because it impairs concentration, reasoning, and problem solving. This hurts your ability to be proficient in your job. So not only will you be unable to think properly, you also won’t be able to perform your job to the best of your ability.
3. Sleepiness puts your health at risk.
Sleep disorders and extreme sleep loss and lead to:
– Heart disease
– Heart attack
– High blood pressure
4. Sleepiness can encourage you to gain weight.
Lack of sleep appears to be related to metabolism. The less you sleep, the more hungry you become, which can lead to obesity if uncontrolled. Not only does sleep deprivation lead to an increased appetite, but it stimulates cravings for unhealthy, high-fat foods.
5. Sleepiness can contribute to depression.
Consistent sleep deprivation can contribute to symptoms of depression. Insomnia has the strongest link to depression. In a 2007 study, those with insomnia were 5 times as likely to develop depression as those without. Insomnia and depression feed each other. Falling asleep is harder once depressed – and at the same time, depression gets worse the less one sleeps.
