Generally, when one refers to sleep disorders, the first thing that comes to mind is lack of sleep, then one speaks of insomnia. However, sleeping too much can also have serious consequences on health and cause chronic diseases, so called hypersomnia.
The Effects of Excess Sleep
A study by Professor Franco Cappuccio of the University of Warwick in Coventry, England, found that "the mortality risk of sleepers less than six hours per night is 12% higher than those who sleep between six and eight hours Per night, and those who sleep more have a mortality risk of 30% higher ". According to him, too much sleep would be more dangerous than insomnia.
Too much sleep means more than nine hours of sleep per night, having trouble getting out of bed in the morning, being tired all the time and feeling a strong urge to sleep throughout the day.
The Centers of Disease Control in the United States conducted a study of 54,269 men and women over the age of 45 who demonstrated that lack of sleep and excessive sleep can lead to serious illnesses: Is that sleeping less than six hours and more than nine hours has adverse health effects.
Excessive sleep could therefore cause the following conditions:
- Risks of coronary artery disease and stroke
- Diabetes and obesity
- Headaches and Migraines
- Emotional and psychological disorders (depression, stress, anxiety)
In addition, research carried out for three years by the University Hospital of Madrid and the University of Colombia in New York brought together 2,700 volunteers and highlighted the fact that excessive sleep affects the cognitive faculties of adults 60 years and over. Those of the "big sleepers" decreased much more than those of patients who slept an average of eight hours per night.
The Nurses' Health Study, one of the most important studies of the major causes of chronic conditions in women, has also shown that abnormal sleep, both short and long, is likely to increase risk Cardiovascular disorders and coronary artery disease.
Other factors in daily life are also related to sleep and health, including poor nutrition, excessive alcohol and tobacco consumption, lack of sport and physical activity, and age.
Sleeping needs by age
The number of hours of sleep depends in fact on the age range, especially since we are all unequal in the face of sleep. A person who has slept four hours can overflow with energy while a person having sleep seven hours instead of eight can feel tired and be idle throughout the day.
The National Sleep Foundation (NSF), an American institute specializing in sleep, highlighted the number of daily hours of sleep required for the well-being of each person according to the age range.
- For newborns 0-3 months of age: between 16 and 18 hours of sleep
- For babies from 4 to 11 months: between 12 and 15 hours of sleep
- For infants aged 1 and 2: between 11 and 14 hours of sleep
- For children between 3 and 5 years of age: between 10 and 13 hours of sleep
- For children who have reached the age of school, between 6 and 13 years old: between 9 and 11 hours of sleep
- For teenagers (between 14 and 17 years old): between 8 and 10 hours of sleep
- For young adults between 18 and 25 years of age: between 7 and 9 hours of sleep
- For adults between 26 and 64 years of age: between 7 and 9 hours of sleep
- For the elderly who are over 65: between 7 and 8 hours of sleep
According to Charles Czeisler, Chairman of the National Sleep Foundation Council, "it is important to see these figures because we spend an average of one third of our lives asleep and our health is largely based on our quality and Duration of sleep. This remains a key issue that affects our life span. "
It is important to note that each case is special if you respect the number of sleeping hours recommended by your age group as mentioned above but you still feel a drop in energy and drowsiness during the day , This may mean that the environment in which you sleep is not appropriate. It is advisable to talk to your doctor.
