Sleeping too much can also be harmful to your health: this is what studies on sleep hygiene say.

Sleeping more than nine hours a day is far from restorative. In fact, according to experts, this habit is often linked to other health problems and can even pose a significant risk to a person's overall physical well-being .

According to the Sleep Institute, hypersomnia is a sleep disorder in which a person sleeps longer than necessary to recover from daily fatigue.

It's worth noting, first of all, that the amount of sleep required depends on each person's age. Newborns, for example, need 20 hours of sleep, while adolescents require between seven and nine hours, and adults a maximum of six to eight hours.

However, each person is unique. Although several studies recommend seven hours, according to the Sleep Clinic, some people may need nine to feel their best. However, sleeping more than 10 hours is considered oversleeping.

"Sleep being altered to fewer or more hours affects the vital function of sleep in humans," the Institute notes.

Neurologist Celia García Malo affirms that sleep plays a vital role for human beings, due to all the functions activated in the body during this period. "While we sleep, metabolic and immunological processes take place that are essential to keeping us healthy," she points out.

Getting adequate sleep helps people recharge and recover from the day's stresses. While the number of hours of sleep needed varies by age and other factors, an adult requires an average of eight hours of deep sleep.

Paradoxically, when you exceed this amount of time, you fall into a light sleep, not the constant or restorative sleep your body needs. So sleeping too much is just as harmful as sleeping too little.

Excessive sleep affects mood, which is why disorders such as depression are related to sleep.

The risk of developing diabetes increases when you sleep too much because it raises blood sugar levels.

It increases the risk of suffering from cardiovascular diseases, which are the leading cause of death worldwide.

Prolonged sleep affects concentration and proper brain activity in daily routine.

It causes metabolic disorders because it leads to less physical activity and leads people to eat outside of their normal schedules. Those affected often experience weight problems such as obesity.

According to the Mayo Clinic, for adults, sleeping less than seven hours a night on a regular basis is linked to poor health, which also includes weight gain, a body mass index of 30 or higher, diabetes, high blood pressure, heart disease, stroke, and depression.

There are factors that can affect the amount of sleep a person needs. These are:

- Sleep quality. If your sleep is frequently interrupted, you're not sleeping well. Sleep quality is just as important as quantity.

- Previous sleep deprivation. If you suffer from sleep deprivation, the number of hours of sleep you need increases.

- Pregnancy. Changes in hormone levels and physical discomfort can lead to poor sleep quality.

- Aging. Older adults need approximately the same amount of sleep as younger adults. However, as they age, their sleep patterns tend to change. Older adults tend to sleep more lightly, take longer to fall asleep, and sleep for shorter periods than younger adults. Older adults also tend to wake up several times during the night.
