Diet, exercise, and step counts get a lot of attention in our daily routine, but there is one important aspect that is often ignored. And that is sleep. Recent research has revealed that lack of sleep has serious effects on the body and mind, which can put life in danger.

effects of sleep deprivation

According to Dr. Sudhir Kumar, Senior Neurologist, Apollo Hospital, if a person gets less than 6 hours of sleep continuously, it can become a major cause of early death. This risk may be more serious than poor diet or lack of physical activity.

brain cleaning during sleep

The brain rests during sleep, but it is not just rest. During sleep, the ‘Waste Clearance System’ of the brain becomes active, which is called the Glymphatic System. This system removes neurotoxins like beta-amyloid from the brain. If you don’t get enough sleep, this cleaning process is not completed, causing dirt to accumulate in the brain. It increases the risk of mental diseases.

Three major dangers of lack of sleep

1. Metabolic Dangers: Lack of sleep increases levels of cortisol, a stress hormone, and ghrelin, an appetite-stimulating hormone. This increases the risk of insulin resistance and obesity.


2. Cardiovascular dangers: Normally blood pressure should reduce at night, but due to lack of sleep it does not reduce, due to which the pressure on the heart increases and the risk of heart diseases increases.


3. Neurological dangers: Lack of sleep reduces the efficiency of the brain, which affects the thinking ability. It can increase the risk of stroke and other neurological diseases.

doctor’s advice

Doctors say that sleep debt cannot be repaid through physical activity or healthy diet. If you are sleeping less, then sweating in the gym or eating salad will not remove the effects of lack of sleep. For this, it is important that you correct your sleep cycle and get enough sleep.
