In a busy life, many people are willing to cut down on sleep time to complete work or take care of the family. However, recent research data shows that chronic sleep deprivation may be closely related to shorter lifespans, even more strongly affecting diet or exercise levels.
According to Brunda MS, a internist at Aster CMI Hospital (India), sleeping less than 7 hours per night for a long time can impair the body's ability to recover. Lack of sleep disrupts the immune system, increasing the risk of cardiovascular disease, high blood pressure, diabetes and obesity. The brain is also affected when memory declines and the speed of information processing is slower.
Experts add that prolonged sleep deprivation also causes hormonal imbalance, increased stress and the risk of depression. Maintaining a habit of sleeping less for a long time can negatively affect overall health and longevity.
Signs that the body is sleep deprived
The body often sends many signals when not fully rested. Sleep deprived people may feel constantly tired, sleepy during the day, and have difficulty concentrating. Mood changes such as irritability, anxiety, or sadness are also common. Some people experience headaches, body aches, or cravings for sugary and fatty foods.
Weakened immune system makes the body susceptible to infections. Skin can become dull, dark circles appear and signs of premature aging. These manifestations show that the body needs rest and recovery.
Long-term effects of low sleep
Sleeping less than 7 hours per night can reduce decision-making ability and increase the risk of mistakes at work. Metabolism slows down, leading to weight gain and hormone disorders that control feelings of hunger. Blood pressure increases and the heart has to work harder, thereby increasing the risk of cardiovascular disease.
These effects accumulate over time, making the risk of chronic diseases higher and affecting life expectancy.
Ideal sleep time
According to experts, most adults need to sleep 7 to 9 hours per night for both the body and brain to recover fully. Children and adolescents need more sleep time to support physical and intellectual development. Older adults may sleep less but still need to ensure sleep quality.
Maintaining a fixed bedtime and wake-up time, limiting caffeine in the evening, avoiding using electronic devices before bed and creating a quiet bedroom environment are measures to help improve sleep quality.
Sleep is not only a rest time but also an important factor determining long-term health. Getting enough and regular sleep each night contributes to protecting cardiovascular health, strengthening immunity and supporting longevity.
