Effects of lack of sleep on the body

You already know the effects of spending a restless night and how you will feel the next day  –tired, moody and without energy. But losing the recommended 7-8 hours of sleep has consequences beyond this. In the long run, the after-effects of lack of rest become latent as it drains your mental abilities and puts health at risk. Science has linked lack of sleep with all kinds of health problems, from weight gain to having a weak immune system.

Today we talk about 10 adverse effects from lack of sleep on our body:

  1. Trouble with thinking and focus.

Concentration, creativity and problem solving skills are not up to par when you do not get a restful sleep.


  1. Accidents.

Feeling half sleep during the day can increase your risk of being involved in a car accident or other workplace mishap.


  1. Mood swings.

Lack of sleep can make you feel sad, emotional and tense. Chronic sleep deprivation can affect your mood and make appear states of anxiety or depression.



  1. Weakened immune system.

Poor sleep weakens the immune system. You are more vulnerable when it comes to being exposed to the most common viruses such as the cold and the flu.


  1. Risk of heart disease.

The lack of rest can lead to an increase in blood pressure and raise levels of chemicals linked to inflammation, both of which appear in heart disease.


  1. Risk of high blood pressure or hypertension.

If you sleep less than five hours a night, your risk of developing hypertension increases.


  1. Risk of diabetes.

Little sleep can affect the release of insulin, the hormone that regulates blood sugar. People who do not sleep well have higher blood sugar levels and an increased risk of type 2 diabetes.


  1. Weight gain.

With lack of sleep, the balance of chemicals that sends signals to your brain when you feel full or hungry turns off. As a result, you are predisposed to overeating when you have actually had enough.



  1. Reduction of sexual appetite.

People who do not get enough sleep often have low libido. In men, this break in sexual behavior can cause a drop in testosterone levels.


  1. Lack of balance and coordination.

Lack of sleep can affect your balance and coordination, making you more prone to falls and other physical accidents.

In brief, the body needs rest as it needs oxygen and nutrients to function well. During sleep, our body “heals itself” and regains its chemical balance. Your brain creates new connections and helps you retain your memory. Without a restful rest, our body and brain will not function properly. This can also seriously affect our quality of life.

Finally, we emphasize the importance of this issue by relying on a review of 16 studies that found that sleeping for less than 6 to 8 hours per night increases the risk of an early death by 12 percent.
