According to Teresa Canet, a neurophysiologist and member of the English Sleep Society (SES), “under normal conditions, an adult who sleeps more than nine hours a day would be sleeping too much”, the expert warns that “it is the same or almost the same It is bad to sleep little than to sleep a lot” and points out that it is dangerous for the body to exceed the hours of sleep.
Among the different risks of sleeping more than nine hours a day, the following stand out:
According to a study from Quebec (Canada) people who sleep more than nine hours a day are 25% more likely to gain weight than those who sleep between seven and eight hours. And it is that, although people maintain a healthy diet, sleeping a lot decreases the available time of activity in the day to day and leads to a decreased physical activity.
Increased risk of developing diabetes
The same Quebec study found that excessive sleep doubled the risk of type 2 diabetes compared to people with a healthy sleep habit. This is because sleeping more than necessary can increase the level of sugar in our body, as it also happens when we sleep very little.
Lack of concentration and aging of the brain
Sleeping excessively decreases concentration and alters the normal activity of the brain on a day-to-day basis. According to Teresa Canet, “When a person sleeps too much on a regular basis, they experience loss of attention span and memory, which slows them down.”

When this occurs, the person suffers from what is known as a “sleep hangover.” In fact, it can be said that sleeping a lot causes drowsiness, as well as causing pain derived from lying down for so many hours, weakness and disorientation.
Although the exact reasons why it occurs are unknown, experts point out that prolonged sleep is usually a light sleep in which a deep and constant state of sleep is not reached. As a consequence, our body does not rest as it should and usually wakes up in the wrong sleep phase.
Increased risk of developing or worsening depression
Mood is closely related to sleep. In fact, various studies state that Lack of or excess sleep can lead to the appearance of diseases such as depression or worsen its symptoms in people who suffer from it. On the other hand, excessive sleepiness may be a consequence of depression, especially if it is accompanied by other symptoms such as appetite disturbances, lack of energy or irritability.
