World Health Day 2026: Are these 5 habits of yours shrinking your brain? Learn from the doctor about surefire ways to avoid brain shrinkage.

News India Live, Digital Desk: Today is ‘World Health Day’, and this year’s theme is giving us the message of being aware of the most important organ of our body i.e. ‘Brain’. In this busy life and digital era, we pay attention to our physical appearance but ignore our mental health. Recent medical reports and neurologists have made a shocking revelation that some of our common everyday habits are ‘shrinking’ our brain. Premature reduction in brain size is an invitation for serious diseases like Alzheimer’s and dementia. Let us know from the doctor what are those habits which are damaging your ‘super computer’. What is ‘Brain Shrinkage’ and why is it dangerous? Shrinking of the brain is a process in which brain cells (Neurons) start dying and the connection between them starts breaking. Although this process is natural with increasing age, today cases of ‘Early Brain Shrinkage’ are being seen even in youth of 30 to 40 years of age. This leads to symptoms like weakening of memory, difficulty in taking decisions and irritability. 5 ‘dangerous’ habits that shrink the brain According to doctors, if you do not make these changes in your lifestyle, your brain can age prematurely: Sleep Deprivation: When you do not get 7-8 hours of deep sleep, the brain is unable to ‘reboot’ itself. Due to lack of sleep, toxic proteins start accumulating in the brain which destroy the cells. Excessive Sugar Intake: Eating too much sugar increases inflammation not only in the body but also in the brain. It affects the part of the brain that is responsible for learning and remembering new things. Loneliness and Social Isolation: Humans are social creatures. People who are less social with others or live alone, their brain activity starts decreasing, which reduces the ‘grey matter’. Lack of physical activity: Lack of exercise reduces the flow of oxygen and blood to the brain. Walking or doing yoga helps the brain maintain ‘neuroplasticity’. Constant stress and multitasking: Doing many things simultaneously and being under stress all the time increases the hormone ‘cortisol’, which directly shrinks the hippocampus (memory center of the brain). Doctor’s advice: How to keep the brain ‘young’ and sharp? On World Health Day, neurologists gave some easy tips to increase brain function. Given: Adopt ‘brain food’: Include omega-3 fatty acids (walnuts, flaxseed), green leafy vegetables and berries in your diet. Learn new skills: Playing a new musical instrument, learning a new language or solving puzzles is a great exercise for the brain. Digital detox: Stay away from mobile phones and screens for at least an hour a day. Meditation: 10-15 minutes daily. Meditation helps preserve the shape of the brain by reducing stress.
