5 Effects of Sleep Deprivation on Your Body


Sleep deprivation is a serious health hazard that can have emotional, physical and psychological effects on your life. When you’re sleep deprived, your brain fails to function properly, thus affecting your emotional state and cognitive abilities. Also, prolonged deprivation can make you vulnerable to developing chronic illnesses.

If you’re taking your sleep lightly and skipping your sleep hours, then a study by the Harvard Medical School will have you rethinking your decision. According to the study, sleeping five hours or less per night increases mortality rate from all causes of death by nearly 15 percent. It’s time you give preference to your sleep or else sleep deprivation will take a toll on your life.

We’ve have compiled five effects of sleep deprivation on your body to help you understand the importance of adequate sleep.

1) Inability to Concentrate

Sleep is necessary to keep your central nervous system on the right track. But, sleep deprivation can disturb the way your body sends signals. When you sleep, neurons form a pathway that helps you learn new concepts and information. Lack of sleep exhausts the brain, making it difficult for you to concentrate or learn new skills. As a result, you become impatient and vulnerable to mood swings, thus affecting your creativity and decision-making abilities.

2) Weak Immune System

Cytokines are substances produced by your body’s immune system that are responsible for fighting foreign invaders such as viruses and bacteria. Lack of sleep prevents the body from producing these protective, infection-fighting substances. As a result, your immune system becomes weak making you prone to chronic illness. Taking adequate sleep is necessary or else your body’s immune system will fail to defend against foreign substances, thus taking a longer time to recover from illness.

3) Increased Risk of Cardiac Problems

Proper sleep keeps your heart and blood vessels healthy as while you’re asleep, your body gets a chance to relax and restore the chemical balance. If you don’t get enough sleep, your body is unable to repair your heart and blood vessels, thus putting you at a higher risk of getting cardiovascular disease and coronary heart disease.

4) Obesity

Sleep deprivation affects two types of hormones, leptin and ghrelin. The former controls the feeling of fullness and the latter controls hunger. If you lack sleep, the brain reduces production of leptin and increases ghrelin, which stimulates your appetite and makes you feel hungry contributing to your weight gain. It can also affect your blood sugar level as sleep deprivation prompts your body to release an increased amount of insulin after you eat. It can result in type 2 diabetes.

5) Impotence

A good night’s sleep plays a vital role in maintaining the testosterone (a hormone that stimulates sex drive, especially in men) level in your body. If you lack adequate sleep, the testosterone level decreases resulting in a reduced libido. In short, getting enough sleep is essential to maintain a good sexual function.

People who miss out on sleep often feel irritated, tired and cranky the next day. But, these are the tip of the iceberg as sleep deprivation can negatively affect a number of systems in your body. It includes a weak immune system, increased risk of diabetes and cardiovascular diseases, impotence, obesity and inability to concentrate. If you want a healthy body, make sure that sleep for at least 7 hours.

If you’re sleeping for recommended hours, but still facing health issues, then you probably need to change your sleep posture and replace your synthetic bedding with organic mattresses, sheets and pillows.
