Sleep is an important part of a healthy lifestyle, but what happens if a person does not sleep at all? This is a question that worries many. Therefore, it is worth understanding how long a person can live without sleep and how this affects his body.
Deadlines without sleep
The length of time a person can survive without sleep varies depending on a number of factors, including age, overall health, and individual body characteristics. However, on average, a person can survive without sleep from a few days to two weeks.
First symptoms
Lack of sleep quickly affects the body.
After just 24 hours without sleep, a person begins to experience difficulty concentrating, memory loss, irritability, and slow reaction times. After 48 hours, they may:
• hallucinations may occur;
• abnormal thought processes;
• decreased coordination of movements.
As practice shows, a person cannot immediately recognize many symptoms.
Long-term effects
Long-term sleep deprivation can lead to serious health problems, including impaired immune system function, cardiovascular disease, depression, and an increased risk of Alzheimer's disease and stroke.
Physiological changes
Lack of sleep also leads to a number of physiological changes in the body. For example, stress levels may gradually increase, and hormone levels such as leptin may begin to decrease.
Effect on the brain
Sleep plays an important role in cleansing the brain of toxins and renewing neural connections. Lack of sleep can lead to disruption of these processes and deterioration of cognitive functions, as well as increase the risk of developing neurological diseases.
