World Brain Day 2026: Sleep's Vital Role in Brain Health
World Brain Day 2026 focuses on how the brain stays active even during sleep.
Dr. S Suresh Sagadevan explains that sleep is not just about resting but is a vital process for the brain.
The brain goes through different stages of sleep, including deep sleep and REM sleep, which are crucial for memory, learning, and emotional well-being.
Poor sleep quality can lead to immediate issues like tiredness and irritability, as well as long-term problems like high blood pressure, diabetes, and depression.
To improve sleep quality, it's important to maintain a regular sleep schedule, avoid screens before bedtime, limit caffeine late in the day, and keep the bedroom quiet and comfortable.
Ignoring sleep problems can have serious consequences, so seeking help early is important.
