Less sleep can become the root of serious diseases, experts told how many hours of sleep is right for a healthy life.

Lack of sleep doesn’t just cause lethargy; Rather, it has a deep impact on your physical, mental and emotional health. It can reduce your ability to work, impair your balance, and even dull the natural glow of your face. Let’s learn how lack of sleep affects your body and recognize the warning signs that should never be ignored.

These are the problems that start emerging in the body when sleep is not complete:
Fatigue and low energy: If you don’t wake up feeling refreshed, feel tired throughout the day, or yawn a lot, these are all signs that you’re not getting enough sleep—or you may be struggling with an underlying sleep disorder. **Mental health problems:** Chronic insomnia can quickly turn into major mental health problems. Mood disorders such as depression and anxiety are also closely linked to persistent sleep problems and sleep deprivation. Research shows that people suffering from insomnia are twice as likely to develop depression.

Neurological problems: Lack of sleep impairs thinking and memory, which can make you forget things or make your brain feel “foggy” while working. This causes neurological symptoms like blurred vision, lethargy, memory loss and slow reaction speed.

Swelling in the eyes: Due to lack of sleep, swelling and dark circles often occur around the eyes, due to which the face looks tired and withered.

Weak Immune System: When you work continuously without giving priority to your health, your immune system gets adversely affected. This increases your chance of getting sick, and it may take longer to recover from viral infections like the common cold or flu.

How much sleep do you need every day?
To stay healthy and fit, adults should aim for 7 to 9 hours of sleep every night. People who do physical exercise regularly usually need 7 to 8 hours of sleep. Elderly people above 65 years of age need 7 to 8 hours of sleep, while children need 10 to 17 hours of sleep depending on their age.
