World Sleep Day is observed globally on March 14th, and this year, the day is being conducted under the theme ‘Make Sleep Health a Priority’ to raise more awareness about sleep habits. On this World Sleep Day, Dr. Jayakumar Rajagopal, Senior Consultant in Respiratory Medicine and World Sleep Society Certified Sleep Specialist at PSG Hospitals, explains the importance of sleep in this article.
World Sleep Day is organized by the World Sleep Society and is celebrated on the Friday before the March equinox each year. This day serves as a reminder that sleep is not just a luxury, but a necessity for our physical and mental well-being, says Dr. Rajagopal.
Why Is Sleep Important?
Dr. Jayakumar Rajagopal explains that sleep is essential for many critical functions in the body. During sleep, our bodies repair muscles, consolidate memories, regulate hormones, and boost the immune system.
Moreover, he notes that inadequate or poor-quality sleep has been linked to a wide range of health problems, including heart disease, diabetes, obesity, weakened immune function, depression, anxiety, impaired cognitive abilities, and decreased productivity and focus.
“A good night’s sleep is not just about the quantity but also the quality. Both the duration and depth of sleep matter. Sleep deprivation or fragmented sleep can lead to poor physical and mental health,” the doctor added.
The Theme of World Sleep Day 2025
Dr. Rajagopal emphasized that each year, World Sleep Day highlights a theme to focus global attention on specific sleep-related issues. The theme for 2025 is “Sleep is Essential for Health”, emphasizing that, like exercise and a balanced diet, sleep is a fundamental pillar of overall well-being. This year’s theme aims to encourage people to make sleep a top priority in their daily lives.
Common Sleep Disorders
Understanding sleep disorders is essential in realizing the significance of World Sleep Day. Dr. Rajagopal highlighted some of the most common issues affecting sleep, including:
- Insomnia: Difficulty falling asleep or staying asleep.
- Sleep Apnea: Breathing interruptions during sleep, which can be dangerous if left untreated.
- Restless Legs Syndrome: A neurological condition that causes discomfort in the legs and disrupts sleep.
- Narcolepsy: A disorder that affects the brain’s ability to regulate sleep-wake cycles.
He adds that if left untreated, these sleep disorders can significantly impact the quality of life and increase the risk of chronic illnesses.
Tips for Better Sleep
To mark World Sleep Day, here are some practical tips from Dr. Rajagopal to improve sleep quality:
- Stick to a regular sleep schedule – Try to go to bed and wake up at the same time every day, even on weekends.
- Create a relaxing bedtime routine – Wind down by reading, meditating, or taking a warm bath before bed.
- Limit screen time before bed – The blue light emitted by phones, tablets, and computers can interfere with your body’s natural sleep-wake cycle.
- Create a comfortable sleep environment – Ensure your bedroom is cool, dark, and quiet. A comfortable mattress and pillows also make a difference.
- Watch what you eat and drink – Avoid heavy meals, caffeine, and alcohol close to bedtime, as these can disrupt sleep.
- Exercise regularly – Regular physical activity can help you fall asleep faster and enjoy deeper sleep, but avoid vigorous exercise close to bedtime.
Conclusion
Dr. Jayakumar Rajagopal concluded by saying, “On World Sleep Day, it’s essential to recognize that sleep is not just about rest—it’s about rejuvenation and overall health. Prioritizing sleep, understanding the risks of sleep deprivation, and promoting healthy sleep habits can help you live a longer, healthier, and more productive life.”
As we celebrate this day, let’s pledge to take better care of our sleep for a healthier tomorrow!
