Signs Your Lack of Sleep Is Slowly Killing You

insomnia effects

We all know that little sleep has immediate effects, such as lack of concentration, drowsiness, clumsiness and decreased proactivity. However, few know the serious long-term consequences that this practice can bring.

A person needs to sleep on average between 7 and 9 hours daily, according to experts, but most adults do not succeed because they have a busy life.

The truth is that those who sleep 6 hours or less per night are exposed to significant risks. According to a study by the University of Texas, after 7 nights of little sleep, we already suffer genetic alterations that could trigger heart problems and obesity, among other diseases.

Then we leave you with a list collected by Huffington Post, where it reports the 8 most “terrifying” effects of sleeping a bit.

1. Increase the risk of stroke

According to a study by the Mayo Clinic (United States), lack of sleep increases the risk of stroke. Adults who regularly sleep less than 6 hours per night are four times more likely to have stroke symptoms.

2. Leads to obesity

Sleeping too little increases appetite and predisposes to cravings for unhealthy, high-calorie food. This is because when we cannot fall asleep, we suffer some hormonal changes that lead to this situation.

Resting for 6 hours or less boosts the production of the hunger hormone, ghrelin, and limits leptin, which helps balance food intake, according to a study published in the Journal of the Academy of Nutrition and Dietetics.

3. Elevates the risk of diabetes

Adolescents who sleep poorly are more resistant to insulin, according to a study published in the Journal Sleep. Another survey also agrees with this.

4. Memory loss

It is not a secret that when you are tired you are more forgetful, but few know that you can suffer permanent cognitive problems due to lack of sleep.

And the less we sleep, we do not benefit from the storage properties of memory that is activated during sleep. In addition, little sleep can cause “brain deterioration,” according to a study from the University of California.

5. Bone damage

According to a study by the Medical College of Wisconsin (USA), lack of sleep can lead to osteoporosis.

In an experiment with mice, the researchers found that bone mineral density and bone marrow decreased in rodents when they were deprived of sleep for 72 days.

6. Increase cancer risk

An investigation of the American Cancer Society determined that sleeping little increases the risk of suffering from certain types of cancer, such as colorectal or breast.

7. You are more prone to a heart attack

Lack of sleep can cause your body to produce more chemicals and hormones that can lead to heart disease, says a study published in the European Heart Journal. The research determined that those who sleep 6 hours or less have a 48% risk of developing or dying from heart disease.

8. It kills you

Another study published in Journal Sleep concluded that those who sleep less than 7 hours per night die younger. It was determined that those who rest little are four times more likely to die within the next 14 years for various diseases, not just heart problems.
