Study shows that sleeping too much is bad

Adequate sleep is essential for the proper functioning of the body. Not doing so increases the risk of suffering from different disorders such as cardiovascular diseases or diabetes . Numerous studies carried out throughout history have shown that sleeping less than eight hours significantly impairs quality of life.

Well, a new research has discovered that sleeping excessively , considering as such lengthening the sleep more than ten hours, increases the chances of dying by more than 30% . This is pointed out by the study led by Keele University, in Staffordshire, published in the “Journal of the American Heart Association.”

How long is it recommended to sleep?

As experts point out, the established pattern of sleep in adults is eight hours, no more, no less. It is the time it takes for the body to repair both blood vessels and cells . That is why it has always been considered that sleeping excessively is healthier than sleeping too little. However, this research points out just the opposite.

The study indicates that people who sleep ten hours a day are 56% more likely to suffer a stroke, as well as 49% more likely to die from a certain cardiovascular disease.

Dr. Chun Shing Kwok, principal investigator, explains that both the quantity and the quality of sleep are two complex factors that need to be studied in depth. Explain that there is a large selection of cultural, social, psychological, environmental, and behavioral influences on sleep . Thus, he considers that this study has a great impact on public health since it shows that excessive sleep is an important risk factor for certain diseases.

Why is sleeping too much bad for your health?

There is no clear data to show that sleeping too much is bad for your health. Certain studies indicate that it modifies the production of substances in the brain , such as serotonin or dopamine , thus increasing the risk of depression.

Additionally, some research claims that lying in the same position for a long period of time can weaken muscles and joints.

Of course, sometimes it is the physical and / or mental health conditions of each person that cause excessive sleep. This is the case of people suffering from depression, who frequently use sleep as a means of escape.

The main consequences of oversleeping are listed below.

  • Cardiovascular disease: sleeping ten hours a day or more is an important risk factor for developing cardiovascular problems. According to the WHO, these types of disorders are the leading cause of death globally.
  • Metabolic disorders: those who do not sleep adequately have weight problems. There is a direct relationship between excess sleep and obesity.
  • Diabetes: Sleeping too much can raise blood sugar levels, which can increase the risk of developing type 2 diabetes.
  • Attention and concentration capacity: prolonged sleep can age the brain at a faster rate, thus generating difficulties when carrying out daily activities.
  • State of mind: and, finally, one of the consequences that occurs most commonly among those who sleep too much is depression. A mental illness that can interfere with daily life, causing symptoms such as ongoing feelings of sadness, loss of interest in favorite activities, and ongoing feelings of fatigue.

The importance of sleeping well

Currently, due to the rhythm of life that an increasing number of people lead, sleep disorders, such as insomnia , are common . Sometimes not enough importance is given to sleeping little or doing it badly; However, if the rest is not adequate, health can suffer significantly.

From a physical point of view, an inadequate night’s rest can lead to tiredness, drowsiness, and decreased attention span and concentration . From a psychological perspective, this fact causes increased irritability, as well as the development of diseases such as depression or anxiety.

Quality of sleep

Experts agree that quality sleep is continuous sleep, without frequent awakenings. It is important to assume that the bed is a place dedicated solely to sleeping , so it is advisable to avoid doing other activities such as watching television or eating. In this way, a sleep routine is established, which includes a series of habits that favor both conciliation and maintenance of sleep.

If you have any kind of difficulty sleeping, it is best to get out of bed and return after 15 to 20 minutes. Staying awake in bed only increases levels of frustration and nervousness.


In conclusion, sleeping excessively is not at all good for your health, both physically and mentally. That is why it is recommended to sleep the eight hours a day that the experts indicate.

In addition, to guarantee a good quality of sleep, it is advisable to maintain stable hours, as well as having favorable conditions in bed. Of course, it is important to avoid alcohol, as well as any type of stimulant at night.
