As we celebrate World Sleep Day on March 14, 2025, it’s the perfect time to pause and reflect on one of the most essential yet often overlooked aspects of our health: sleep. TheGlitz spoke to one of Mumbai’s most trusted doctors, Dr Raima Kapoor and she says, “In my practice as a physician in Mumbai, I often encounter patients who underestimate the importance of quality sleep. It’s time to change that mindset and embrace sleep for the essential, restorative process it truly is.”

More Than Just Rest
Dr Raima lists the benefits:
- Physical Health Benefits
- Restoration & Repair: During deep sleep, the body works to repair tissues, muscles, and cells. Growth hormone is released, promoting tissue growth and muscle repair.
- Immune System Boost: A good night’s sleep strengthens the immune system. Lack of sleep can make us more vulnerable to infections and diseases, as our body’s defense mechanisms weaken.
- Weight Management: Poor sleep has been linked to imbalances in hunger hormones, leading to overeating and weight gain. Adequate sleep helps maintain a healthy metabolism and supports weight management.
- Mental Health & Cognitive Function
- Memory Consolidation: Sleep is essential for memory formation. During sleep, the brain processes and consolidates information from the day, helping you retain and recall memories more easily.
- Emotional Well-being: Lack of sleep affects emotional regulation, leading to irritability, increased stress, and mood swings. Quality sleep helps regulate mood and supports mental clarity, creativity, and problem-solving.
- Cognitive Performance: Sleep helps maintain cognitive functions such as concentration, focus, and decision-making. When sleep-deprived, these cognitive skills diminish, making it harder to function efficiently at work or in daily tasks.
- Chronic Disease Prevention
- Heart Health: Chronic sleep deprivation is associated with an increased risk of hypertension, heart disease, and stroke. Good sleep helps regulate blood pressure and reduces inflammation, which plays a key role in cardiovascular health.
- Diabetes Risk: Consistently poor sleep has been linked to insulin resistance, a key factor in the development of Type 2 diabetes. Proper rest helps maintain normal blood sugar levels and supports overall metabolic function.
How Much Hours?

Dr Raima says, “The amount of sleep a person needs can vary depending on their age, lifestyle, and individual health needs, but the general guidelines from health experts suggest…”
- Adults (18-64 years): 7-9 hours
- Teens (14-17 years): 8-10 hours
- Children (6-13 years): 9-11 hours
- Toddlers (1-2 years): 11-14 hours
Tips
- Create the right Environment: Ensure your bedroom is cool, quiet, and dark. Invest in a comfortable mattress and pillows.
- Establish a Sleep Routine: Go to bed and wake up at the same time every day, even on weekends. This helps regulate your internal clock.
- Limit Stimulants: Avoid caffeine, nicotine, and heavy meals close to bedtime. These can interfere with your ability to fall asleep or stay asleep.
- Disconnect Before Bed: Limit screen time at least an hour before sleep. The blue light emitted by phones, tablets, and computers can interfere with your natural sleep cycle.
- Relaxation Techniques: Practice relaxation techniques such as deep breathing, meditation, or reading a book to help ease your mind.
