The Dangers of Under Sleeping

Under sleeping is a problem for many individuals today. There are various adverse effects associated with sleep deprivation. Not sleeping appropriately affects different parts of the body in different ways. In this article, we will highlight the various ways under sleeping affects the different systems in the body. Sleep is an important part of everyday life and should be treated as such. Here are the ways not sleeping can affect you today(systemic effect of undersleeping):

Immune System

 Your immune system produces substances that protect the body and fight infections while you sleep. Some of these substances include cytokines that fight viruses and bacteria in your body. Cytokines help you defend your body and keep you healthy, and if you do not sleep enough, your production of these substances will reduce. Sleep deprivation will ultimately result in you having a weak immune system and therefore expose your body to various illnesses. Your risk of having severe disease increases the longer you under sleep, and it would also affect your recovery speed if you are already ill. 

Digestive System

 Lack of proper sleep can improve your chances of becoming overweight or obese. Leptin and Ghrelin (hormones in your body) production is affected when you under sleep, and these hormones are responsible for the feeling of fullness and hunger. Ghrelin tells the brain when it's time to eat while Leptin tells the brain when you have eaten enough. Lack of sleep will cause the production of these hormones to become unstable, therefore leading to overeating.


Sleep deprivation also makes you tired and reduces your ability to perform physical activities. This will make you gain weight if you are overeating and not burning enough calories. Higher levels of insulin is produced when you do not get enough sleep, and this improves fat storage and increases the risk of you getting diabetes.


Central Nervous System

Under sleeping affects the central nervous system, which is the information center of the body. Sleeping well is important to keep your nervous system working properly. Under sleeping will seriously affect how your nervous system sends and receives information. While you are asleep, nerve cells in your brain form pathways that helps you to retain new information that you have learned. Under sleeping leads to mental exhaustion and poor mental performance. Your concentration coordination will also be affected. Your body will delay sending and receiving signals, thereby making you sluggish.

Under sleeping affects your emotional state and makes you have mood swings and become less patient. Your decision-making will also be hampered, and your creativity will be stifled. Hallucinations can start to occur if this continues for a long time, and you may experience mania if you have a history of bi-polar disorder.


Under sleeping is a bad habit that harms your body. Having the required doubt of sleep per day is important to keeping your body in tip-top shape. Seek medical advice if you find it hard to get sufficient sleep on your own, as this would help you find a solution that will work for you. Sleeping sufficiently is key to having a healthy mind and body.
