Experts confirm it: We sleep less and less. According to the World Association for Sleep Medicine (WASM), "Sleep problems are a global epidemic that threatens the health and quality of life of more than 45% of the world's population." "In addition to a balanced diet and regular exercise, sleeping well is one of the three cornerstones of good health," the agency said in an informative note. And according to Shirley Cramer, executive director of the Royal Society for Public Health (RSPH), "many say they only sleep four to five hours a day, but that's not something to brag about."
Sleep – an important function
Sleep has an important function for the body (Canoë, 2014), but it also enables the person to distance themselves from a situation.
Causes of Lack of Sleep
Several reasons can prevent people from sleeping.
Do you want to perform
Among other things, the performance issue can result in a person having too much work to restrict their sleep. Similarly, medium-term students often prioritize study or deadlines to the detriment of their calm. Concern for performance isn't the only factor in a person's insomnia.
People who are under a lot of stress often have difficulty falling asleep. This is especially the reality of a caregiver. The illness of his loved one puts a lot of pressure on him, which causes the little mouse to spin in his head.
A sleeping guilt
Sleep disorders such as insomnia or sleep apnea can also cause sleep guilt. For example, people with a mental illness such as depression, bipolar disorder, or schizophrenia are likely to be significantly affected by this reality.
For example, a person with depression may have difficulty falling asleep. On the contrary, she can sleep for hours and still feel tired when she wakes up. Having failed to get restful sleep, she remains in the sleep debt; This is why it is said that rest is an indicator of a person's mental state.
Negative effects of lack of sleep
"We know from various studies that sleep deprivation puts you at a much higher risk of cardiovascular disease, cancer, diabetes and depression," Cramer told the BBC.
These are some of the ways little sleep can affect your health.
On the physical plane
"Lack of sleep makes us eat worse," says Cramer. According to a study developed by the RSPH, more than a third of people eat poorly when they sleep little.
On a psychological level
The person who is more tired will have difficulty concentrating; You can become irritable or make careless mistakes. their ability to pay attention and concentrate is reduced. Likewise, a person who drives or works in an environment that requires a high level of alertness is at greater risk of a major accident if reaction time is slowed and alertness is decreased. (Canoe, 2014).
The ability to make informed decisions, bad moods, hyperactivity, impulsiveness, and changes in the intensity of emotions are also some of the effects of a lack of sleep.
