Do you often wake up feeling tired even after what seems like a full
night’s sleep? Many people assume sleep is simply rest, but in reality, it is
one of the most important biological processes for maintaining overall health.
Observed every year on the Friday before the March equinox, World Sleep Day
will be celebrated on March 13, 2026. The initiative is organised by the World
Sleep Society to spread awareness about healthy sleep habits and sleep
disorders.
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.
