Until recently, most of us associated the word 'fitness' with toned muscles, weight goals, or a step count on our smartwatches. But as our lives grow more complex and cognitively demanding, there's a growing shift: the brain is becoming the new biceps.
“What good is a fit body if the mind is foggy, forgetful, or fatigued? In the clinic, I often tell my patients: We spend hours working on our physical health, but when was the last time you thought about your brain’s fitness? The truth is, your daily choices today are laying the foundation for how sharp or how sluggish your brain will feel decades from now,” said Dr Avinash Kulkarni, Consultant Neurologist, Gleneagles BGS Hospital, Kengeri, Bengaluru.
In this article, we explain how to build lasting brain health through small, consistent habits that anyone can start today. We spoke to
Preventive Neurology: Think Ahead, Stay Ahead
Unlike emergency medicine, which steps in when something goes wrong, preventive neurology focuses on staying ahead of the problem. It's about understanding that the brain, like any other organ, ages, and just as we take care of our heart or bones, we need to care for our brain, too.
“Cognitive decline does not come with warning bells. It’s often a quiet shift: misplaced keys, forgotten names, lost trains of thought. These early signs, while subtle, are our chance to act. Neuroplasticity, the brain’s ability to rewire itself, never disappears. But it needs the right environment to work optimally,” said Dr Kulkarni.

Move Your Body, Move Your Brain
Yes, cardio is good for your heart, but did you know it is also fuel for your neurons? Physical exercise increases blood flow to the brain, improves memory, and even stimulates the growth of new brain cells. Just 30 minutes of brisk walking, cycling, or dancing most days of the week can boost mood and mental sharpness. A study published in Proceedings of the National Academy of Sciences found that aerobic exercise training increased the size of the anterior hippocampus, leading to improvements in spatial memory.
If the gym isn’t your thing, try gardening, yoga, or even cleaning your house to a music playlist. Any movement that gets your heart pumping is also lighting up your brain.
Sleep: The Night Shift Cleaner for Your Brain
“Sleep is often considered an optional luxury. However, neurologically, sleep is when the housekeeping begins. During deep sleep, the brain clears out toxins linked to conditions like Alzheimer’s. Skimping on rest regularly has been shown to accelerate memory problems and emotional instability,” added Dr Kulkarni.
Good sleep hygiene isn’t rocket science. Go to bed at the same time each night, avoid caffeine late in the day, and keep screens out of the bedroom. Your brain will thank you.
Digital Detox: Reclaiming Mental Space
Our devices are stealing our attention spans. Constant multitasking, notifications, and doomscrolling train our brains to expect distraction. Over time, this leads to mental fatigue, irritability, and inability to focus deeply.
You don’t need to delete your apps, but setting boundaries can be transformative. Take 30 minutes to step away from the screen before bed. Designate phone-free meals. Go for a walk without your earbuds. These micro-breaks give your brain a chance to breathe, reset, and recalibrate.

Eat Smart for a Sharper Brain
What you eat directly affects how your brain functions. Diets rich in omega-3 fatty acids (like walnuts, flaxseeds, and fish), antioxidants (found in berries, greens, and turmeric), and whole grains support memory and cognitive longevity.
Limit highly processed foods, linked to inflammation, a known risk factor for cognitive decline. Staying hydrated is also crucial, as even mild dehydration can impair short-term memory and focus.
Don’t Let Stress Settle In
Stress isn't a mental load, it's a neurological one. “Chronic stress fills the brain with cortisol, which, over time, damages the hippocampus, the center of memory. You don’t need a retreat in the mountains to find calm. Try deep breathing for five minutes, a quick journaling session, or listening to soothing music. The brain thrives in environments where it feels safe, calm, and appreciated,” advised Dr Kulkarni.
Watch Out For The Warning Signs
If you or someone you know is consistently experiencing forgetfulness, word-finding difficulty, or unusual mood swings, don’t brush it off as 'just stress' or 'old age.' Early intervention is key. A neurological consultation, along with memory tests and imaging if needed, can help identify problems early, sometimes before they become irreversible.
Daily Brain-Boosting Habits Across Age Groups
No matter your age or lifestyle, a few brain-friendly habits go a long way:
- For children: Limit screen time, encourage outdoor play, and maintain consistent sleep routines.
- For young adults: Watch your sleep and stress, practice focused work, and avoid over-reliance on multitasking.
- For middle-aged adults: Prioritise physical activity, engage in hobbies, and get regular health check-ups.
- For seniors: Keep learning, whether it’s a new language, a card game, or a puzzle. Social interaction also keeps the brain healthy.
Bottomline
Dr Kulkarni concluded, “The mind is what makes us who we are, our thoughts, our memories, and our ability to love, laugh, and dream. And like any valuable possession, it deserves care. So let’s shift the narrative. Let’s start treating brain health as essential, not optional. Because while grey hair may be inevitable, a sharp mind isn’t just possible, it’s worth striving for, every day.”
