Recent studies show that sleep problems are becoming increasingly common. A 2025 survey found that 59% of Indians get less than six hours of uninterrupted sleep, which is far below the recommended amount. The World Sleep Day 2026 theme this year is “Make Sleep Health a Priority”, emphasises the importance of recognising sleep as a pillar of overall health, just like nutrition and exercise.
Dr. Anuradha T Consultant, Pulmonology at STAR Hospitals, Hyderabad, throws light on how quality sleep plays a vital role in maintaining physical health, emotional well-being, and daily productivity.
Why Sleep Is Important for the Body
Sleep is not just a period of inactivity. During sleep, the body performs several essential functions that support health and recovery.
Some of the key benefits of good sleep include:
Improves memory and learning: During sleep, the brain processes and stores information gathered during the day, helping improve concentration and memory.
· Strengthens the Immune System: Quality sleep helps the body fight infections by supporting immune cell activity.
· Maintains Heart Health: Sleep helps regulate blood pressure and reduces strain on the heart.
· Supports Metabolism and Weight Control: Poor sleep can affect hunger hormones and increase the risk of weight gain.
· Improves Mood and Mental Well-Being: Adequate sleep reduces stress, anxiety, and emotional instability.
Even small improvements in sleep habits can significantly improve overall health and quality of life.
How Much Sleep Do Adults Need?
According to sleep specialists, most adults require between 7 and 9 hours of sleep each night to function optimally.
Teenagers and young adults often require slightly more sleep, while older adults may experience lighter sleep but still need adequate rest. Consistency is equally important. Maintaining a regular sleep schedule helps regulate the body’s internal clock, also known as the circadian rhythm.
Common Sleep Disorders
Sleep disorders can affect people of all ages and often remain undiagnosed.
Some of the most common sleep disorders include:
· Insomnia: Difficulty falling asleep or staying asleep.
· Obstructive Sleep Apnea (OSA): Repeated pauses in breathing during sleep due to airway obstruction.
· Restless Leg Syndrome: An uncomfortable urge to move the legs, usually during rest.
· Narcolepsy: A neurological disorder that causes excessive daytime sleepiness.
In India, sleep disorders are increasingly common. Studies show that 37.4% of the population may experience obstructive sleep apnea, while around 25–33% of adults suffer from insomnia. Many people ignore symptoms like loud snoring, frequent awakenings, or daytime fatigue, assuming they are normal. However, these may be signs of a serious sleep disorder.
When Lifestyle Changes Are Not Enough
Simple lifestyle changes can often improve sleep quality.
These include:
· Reducing screen time before bedtime
· Limiting caffeine in the evening
· Maintaining a consistent sleep schedule
· Managing stress and relaxation techniques
However, if symptoms such as loud snoring, breathing pauses, choking during sleep, or excessive daytime sleepiness persist, medical evaluation is important.
Sleep Study Test (Polysomnography)
A sleep study, also known as polysomnography, is an overnight diagnostic test that records several body functions during sleep.
The Test Monitors:
· Brain activity
· Breathing patterns
· Oxygen levels
· Heart rate
· Body movements
This helps doctors diagnose conditions such as sleep apnea and other complex sleep disorders accurately.
