Cigarettes were once considered the biggest silent killer, but now doctors are pointing towards a new and equally dangerous habit – continuous lack of sleep. In fact, medical experts say that chronic sleep deprivation i.e. not getting complete sleep for a long time is becoming as dangerous as smoking in today’s time. Its effect is not visible immediately, but gradually it harms almost every system of the body.

In today’s fast-paced life, staying up late at night, waking up early, watching screens for hours and thinking about managing sleep has become common. Many people believe that 5 hours of sleep is enough for them, but doctors call it a dangerous illusion. Sleep is not just rest but an active process of repair and recovery of the body, when it is continuously reduced then damage starts accumulating inside the body, due to which heart, immunity and mental health are affected.

How is lack of sleep silently harming the body?

According to experts, today lack of sleep is playing the same role as smoking did a few decades ago. Poor sleep increases inflammation in the body and the natural repair system starts weakening. Its symptoms are not visible in the initial stages, but with time it can become the cause of serious diseases. Even if a person eats right or does exercise, experts also say that the first impact of lack of sleep is on the heart, it increases blood pressure, increases swelling and the risk of heart disease and stroke increases manifold. Along with this, metabolism also starts deteriorating. At the same time, due to lack of sleep, hunger increases, craving for sweets and junk food increases and insulin sensitivity decreases. This increases the risk of obesity, type 2 diabetes and metabolic disorders.

How important is sleep for immunity and brain?

Experts say that the immune system strengthens itself during sleep. At the same time, due to lack of sleep, the body falls ill quickly and recovery also takes more time. Sleep is also very important for the brain, it helps in clearing toxins and balancing emotions. Prolonged lack of sleep can increase problems like anxiety, depression, poor memory, lack of knowledge and brain fog. Apart from this, doctors also clearly say that sleep is not an option, most adults need 7 to 9 hours of sleep daily. For teenagers, this requirement is 8 to 10 hours, whereas the elderly also need to sleep for at least 7 hours. At the same time, doctors also say that it is completely wrong to assume that the body has become accustomed to less sleep. In fact, the body keeps accumulating slip debt, which causes damage internally.

What are the early signs of lack of sleep?

Lack of sleep often appears in small signs. Which people ignore. Such as feeling tired all the time, irritability, mood swings, lack of focus, frequent headaches, excessive caffeine dependence, low motivation and increased desire to eat unhealthy food. Doctors say that if you need an alarm, coffee or a catch up slip on the weekend, then it is a sign that the body is already struggling. Doctors also say that sleep is not a luxury but the foundation of health.
