I am a neurologist, these are my ‘top 10 lifestyle and dietary tips to reduce the risk of chronic diseases and promote healthy longevity'
In a recent post on X, Dr Kumar shared his 'Top 10 Lifestyle Habits & Dietary Preferences that Reduce the Risk of Chronic Diseases and Promote Healthy Longevity.' These include eating a whole-food diet rich in vegetables, fruits, legumes, whole grains, nuts, seeds, and lean meat; exercising regularly (at least 150 minutes of moderate activity per week plus muscle strengthening); and sleeping 7-9 hours a night. He also recommends avoiding tobacco and limiting alcohol, maintaining a healthy weight and waist circumference, managing stress through mindfulness or time in nature, and cutting back on excess salt and added sugar.
Dr Kumar highlights the importance of regular health screenings for early detection of conditions like hypertension, diabetes, and cancer. He also stresses the value of strong social ties, as powerful as quitting smoking in reducing mortality risk, and encourages daily sunlight exposure and adequate vitamin D. A bonus tip: Keep your brain active with reading, puzzles or learning new skills to lower dementia risk.
Neha Cadabam, senior psychologist and executive director at Cadabams Hospitals, tells indianexpress.com, 'While all ten habits are valuable for overall health, maintaining meaningful social connections stands out as one of the most powerful factors in delaying cognitive decline. From a psychological perspective, regular social engagement keeps the brain active, encourages emotional expression, and provides a buffer against chronic stress.'
Top 10 Lifestyle Habits & Dietary Preferences that Reduce the Risk of Chronic Diseases and Promote Healthy Longevity

When individuals engage in conversation, solve problems together, or even share emotional experiences, multiple areas of the brain are activated. 'This kind of mental stimulation is essential for preserving memory, attention, and executive function over time. Social connection also reduces the risk of depression and anxiety, both of which are linked to faster cognitive deterioration,' notes Cadabam.
For urban professionals, Cadabam notes, the key is to integrate these habits into existing routines rather than viewing them as additional tasks. Physical activity, for example, does not always require gym time. Walking during calls, taking the stairs, or engaging in short guided home workouts can be just as effective when done consistently.
Meal planning becomes more manageable with small steps, such as prepping ingredients in advance, using simple recipes, or batch-cooking for a few days.
Cadabam states, 'As for sleep, creating a regular wind-down routine is essential. Setting a consistent bedtime and limiting screen time before bed can help signal to the brain that it's time to wind down. Importantly, adults must permit themselves to rest. In high-performance urban cultures, rest is often undervalued, but protecting sleep time is an investment in long-term mental clarity.'
Dr Kumar mentions that loneliness is linked to mortality risk, similar to smoking or obesity. According to Cadabam, loneliness is not just an emotional experience; it activates physiological stress responses in the body, which trigger the release of stress hormones like cortisol. Over time, elevated stress hormones can contribute to inflammation, weakened immune function, poor heart health, and disrupted sleep patterns.
In addition, individuals who feel isolated are less likely to engage in health-promoting behaviours such as regular exercise, balanced eating, or routine medical check-ups. Meaningful relationships offer emotional support, help regulate stress, and give a sense of belonging and purpose — all of which are essential for a long and healthy life.

Animals to help kids with disabilities focus, connect in Kerala
THIRUVANANTHAPURAM: Studies the world over have shown how animal-assisted therapy helps people with mental and neurodevelopmental conditions, and even age-related cognitive impairment. Now, for the first time in the state, the National Institute of Physical Medicine and Rehabilitation (NIPMR), an autonomous institution under the state social justice department, has come up with a project to use animal therapy for children with autism. Social Justice Minister R Bindu recently announced the initiative. In the first phase, trained dogs will be used to address neurodevelopmental conditions in children. Studies will also be conducted on using farm animals for assisted therapy at a later stage. 'Animal-assisted therapy, or AAT, is a structured, goal-oriented intervention where trained animals form an integral part of therapy, guided by qualified professionals. Research shows that AAT can lower blood pressure, reduce anxiety, improve posture, balance, and alertness, and boost confidence, motivation, and social skills,' Chandrababu C, executive director in charge of NIPMR, told the TNIE. As part of its pilot project, Thrissur-based NIPMR will employ the services of a trained golden retriever to interact with autistic children in the age group of four to seven. 'Services of the dog, who helped improve the condition of an autistic child, will be put to use for a larger group,' said Anna Daniel, principal of the Bachelor of Occupational Therapy Programme at NIPMR.

NAFLD in kids: Harvard-trained doctor explains why this silent liver disease is on the rise
Dr. Saurabh Sethi highlights the alarming rise of non-alcoholic fatty liver disease (NAFLD) in adolescents due to unhealthy diets. Consuming sugary foods like pastries and soft drinks leads to excess fructose conversion into liver fat, potentially causing NAFLD. Untreated NAFLD can progress to severe liver issues, including cirrhosis, possibly requiring a liver transplant. Non-alcoholic fatty liver disease (NAFLD) is increasingly becoming common among adolescents and young adults . Modern lifestyle factors, including poor diet, sedentary habits, and obesity, are key drivers of this issue. Dr. Saurabh Sethi, a California-based gastroenterologist trained at Harvard and Stanford, has now shared the shocking information on how the incidence of NAFLD is rising among kids . Dr. Sethi has explained how diet plays a key role in increasing the risk of NAFLD in kids. What is NAFLD Non-alcoholic fatty liver disease (NAFLD) is a common condition where fat builds up in your liver. It affects people who consume little to no alcohol. NAFLD is often linked to being overweight and can usually be treated with healthy lifestyle changes. Also referred to as metabolic dysfunction-associated steatotic liver disease (MASLD), this is a silent disease with few or no symptoms. In some cases, people may not experience any symptoms even if they develop cirrhosis due to nonalcoholic steatohepatitis (NASH), also referred to as metabolic dysfunction-associated steatohepatitis (MASH). What makes NAFLD even more dangerous is that if left untreated, it can progress to chronic conditions such as non-alcoholic steatohepatitis (NASH), liver fibrosis, cirrhosis, and even liver cancer. This, over time, may also increase the risk of cardiovascular disease and type 2 diabetes.

Some people do not realise they have the condition until they discover it in some other test. Some of the symptoms include: Chronic fatigue Feeling generally unwell Liver pain or discomfort in the upper right side of your abdomen, under the ribs What causes NAFLD in children Dr. Sethi revealed that an unhealthy diet is one of the biggest reasons why children develop this condition. He explained that feeding children sugary foods can lead to NAFLD. 'Serving your kid sugary foods like pastries, soft drinks, or cookies can be harmful. Sugar is 50% glucose and 50% fructose. While glucose provides energy to the whole body, excess fructose is converted into fat in the liver, potentially leading to fatty liver,' he said, in a video shared on Instagram.

'If untreated, it can progress to severe liver issues including cirrhosis, which may require a liver transplant in extreme cases,' the doctor said. How to prevent The best way to prevent NAFLD is to focus on the lifestyle factors that are in your control, such as diet and exercise Eat a healthy, balanced diet rich in whole grains, vegetables, fruits, lean proteins, healthy oils, and low-fat dairy products. Maintain a healthy weight Exercise regularly If you are overweight, lose the extra pound.

Complaining all the time? Neuroscientist explains why this is bad for the brain and how to fix it
Neuroscientist Emily McDonald explains that constant complaining negatively wires the brain, strengthening pathways that focus on problems and shrinking the prefrontal cortex, impacting focus and decision-making. This habit makes individuals less attractive and puts them in 'victim mode.' However, fostering positive thoughts and gratitude can reverse this, improving focus and enabling a more joyful outlook. Are you someone who constantly complains, judges, and criticizes? Well, this behaviour may be doing you more harm than you realise. Beyond spoiling your mood, this could also be changing your brain for the worse. Emily McDonald is an Arizona-based neuroscientist and mindset coach, has explained the downside of being a chronic complainer. 'Complaining, judging, or criticizing others can actually change your brain to make you less focused and productive and decrease your problem-solving skills,' the neuroscientist said. She also explained the science behind it and also shared some effective ways to fix it. Constant complaining wires your brain negatively When you make complaining a habit, your brain starts to feed off negativity and starts to notice problems first. 'Every time you complain or criticize, you strengthen that pathway in your brain. This is Hebb's law: neurons that fire together wire together. So if you're constantly focused on what you don't like, you are wiring your brain to see more problems,' McDonald said. Second, this behaviour can actually shrink the region of the brain responsible for focus and decision-making. This means judging and criticizing actually messes up your brain's ability to make right and informed decisions. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like No annual fees for life UnionBank Credit Card Apply Now Undo 'Studies show that chronic stress and negative thinking can actually shrink your prefrontal cortex, and this is the part of your brain responsible for focus, emotional regulation, and decision making. You're literally weakening the part of your brain that helps you solve problems while strengthening the pathways that help you point them out,' she explained, in a video shared on Instagram. Guess what? Complaining is not really an appealing trait. 'Research shows that complaining and criticizing actually makes you less attractive,' she adds. Constant complaining puts your brain into 'victim mode,' which could make you feel powerless to change your circumstances. How to fix it Well, if you have developed a habit of complaining, well, don't worry, you can absolutely reverse it. How? By fostering positive thoughts. Instead of turning to what's wrong with something, focus on yourselves. Something that motivates you, and inspires you to look forward to. 'Thinking positively and expressing gratitude strengthens the prefrontal cortex, which improves your ability to focus and create the life of your dreams. Every time you speak or type a comment on here, you are training your brain. So train it to look for joy and abundance because you don't get what you want in life you get what your brain is wired for,' the neuroscientist shares. Bollywood stars react sharply to supreme court's stray dog order Where to start? It begins with awareness. Breaking out of this complaining and judging mindset starts with awareness. When you catch yourself complaining, shift your focus toward solutions or gratitude.
