Certain everyday habits -- like poor sleep, stress and multitasking -- can quietly weaken your brain. Making simple lifestyle can help protect your mental health.
We often focus on diet, exercise or routine check-ups to safeguard our health but the brain -- our most vital organ -- tends to get overlooked.
What's surprising is that many everyday choices, which feel harmless or even normal, can gradually erode brain function without us realising it.
From staying glued to screens late at night to letting stress run unchecked, these subtle habits can quietly chip away at memory, focus, and long-term mental sharpness, warns gut health expert Dr Pal Manickam in a recent social media post.
Understanding these risks early and making small lifestyle changes can go a long way in protecting your brain and keeping it active, resilient and healthy.
Here, he says, are 10 things you might be doing wrong
1. Skipping deep, restful sleep
Without enough quality sleep, your brain struggles to clear toxins, store new memories and maintain focus.
2. Sitting too much
Prolonged inactivity cuts blood flow to the brain, risking shrinkage of memory-related regions.
3. Trying to multitask all the time
Jumping between tasks drains attention, reduces efficiency and overloads working memory.
4. Poor diet choices
Too many processed foods and sugars inflame your body and brain, harming neural connections.
5. Living under constant stress
Excess cortisol (the stress hormone) can damage the hippocampus, disrupting memory and sleep.
6. Isolation from others
Sparse social interaction amplifies the risk of depression and cognitive decline.
7. Listening to loud music via headphones
Hearing damage forces your brain to work harder, increasing dementia risk over time.
8. Neglecting mental exercise
Without puzzles, learning, reading or new challenges, your neural networks weaken.
9. Staying under-hydrated
Even mild dehydration dulls focus, memory and reduces brain blood circulation.
10. Bright screens before bedtime
Blue light messes with melatonin production, harming sleep and memory consolidation.
