In modern society, lack of sleep is an increasingly common problem, with consequences that go far beyond simply feeling tired the next day. But to what extent can lack of sleep go? Could it really lead to death?
The deadly dangers of lack of sleep
Chronic lack of sleep can put significant pressure on the cardiovascular system. There are studies that show that sleep deprivation is related to an increased risk of hypertension, coronary heart disease and even strokes. Not resting adequately can trigger adverse changes in blood pressure and heart function, thereby increasing the risk of serious cardiovascular events.
In turn, sleep plays a crucial role in regulating the immune system. Our natural defenses can be weakened, making us more susceptible to diseases and infections. It can also make it harder to recover from existing illnesses, increasing the risk of serious and even fatal complications.
Not sleeping for a long time can have deadly consequences in terms of road and work safety. It causes drowsiness and lack of concentration that can drastically increase the risk of car and work accidents. This endangers the life of the individual and also those around him.
Additionally, this trend can have a devastating impact on mental health. It is associated with an increased risk of mood disorders, such as depression and anxiety. They are problems that affect a person's quality of life and can also increase the risk of suicidal behavior.
In addition, short-term memory problems are experienced, manifested in frequent forgetting. It also influences coordination and motor skills, increasing clumsiness and the tendency to drop objects.
During sleeping hours, the body eliminates toxic substances called oxidants that are produced by daily metabolism. These substances are collected and sent to the blood for elimination through the cerebrospinal fluid. It circulates through the central nervous system, including the brain and spinal cord.
According to Rodríguez Molina, a doctor specializing in brain science, if the brain does not control this oxidation process, it could cause damage or complicate diseases. Cerebrospinal fluid performs four vital functions: clearing oxidants during sleep, nourishing parts of the nervous system, maintaining acid-base balance, and contributing to oxygenation.
Even short naps can offer some relief. However, the most alarming risk comes after prolonged periods without sleep, such as more than 72 consecutive hours. At this point, the body faces extreme stress that can result in the alteration of the multiple vital functions already mentioned.
Lack of sleep is not a trivial problem. Beyond fatigue and tiredness, chronic sleep deprivation can have deadly consequences for our health and safety. It is essential to prioritize adequate sleep and seek help if you experience problems falling asleep or staying asleep throughout the night.
