'I'm an NHS doctor - five common daily habits could quietly age your brain'

Dr Amir Khan, an NHS GP, has revealed five daily habits that could be "quietly ageing your brain". Given that the brain oversees virtually all bodily functions, it's arguably our most precious organ, making proper care absolutely essential, which is why Dr Amir wanted to issue the warning to make people aware.

The Alzheimer's Association recommends several practices for maintaining brain health: regular physical activity, nutritious eating, adequate rest, mental stimulation through activities like reading or puzzles, and maintaining social connections. Dr Amir has delved deeper into certain everyday behaviours that might be causing more damage than benefit.

Constant multitasking

Dr Amir explained that whilst perpetual multitasking might leave us feeling "productive," he cautioned that "jumping between tasks stresses the brain, and it can weaken short-term memory and increase our cortisol levels," which is far from ideal.

He noted that "over time," this pattern can significantly affect your ability to concentrate and manage emotions effectively.

Chronic sleep deprivation

"Every one bad night [of sleep] impacts memory and attention," he cautioned, explaining: "Long-term lack of sleep, particularly deep sleep, limits the brain's lymphatic system.

"That's the brain's waste disposal system, increasing plaque formation on the brain, which is linked to Alzheimer's, dementia".

Doom scrolling

It might be incredibly tempting to snuggle into bed and while away the hours on TikTok or Instagram, soaking up hilarious clips or the latest fashion splurges, but it appears this habit could be detrimental to your brain's wellbeing.

Dr Amir cautioned: "Hours of passive scrolling overstimulates the brain, triggers the stress response, and reduces dopamine sensitivity."

Such activities can adversely affect both "memory and mood".

He further mentioned that "the blue light exposure before bed impairs melatonin release, affecting deep sleep," suggesting it's beneficial to engage in a screen-free activity before hitting the hay.

Skipping meals

Dr Amir highlighted that "skipping meals, especially breakfast," can significantly impact your brain's health over time.

He explained: "Glucose is the brain's primary fuel. Intermittent fasting can be helpful in some cases, but skipping meals too often can reduce concentration and trigger brain fog, especially in people with busy lives or hormonal fluctuations".

No social contact

"Social interaction is protective," Dr Amir underscored, noting that "studies show loneliness is as harmful to cognitive health as smoking 15 cigarettes a day".

He added: "Socialising boosts cognitive reserve, and reduces dementia risk. Even just chatting with a friend or neighbour".

Dr Amir concluded his video by advising viewers to "keep your brain healthy by not doing those five things".

In the comments section, an individual expressed gratitude, saying: "Very useful reminder, thank you. I have some changes to make!"

Another chimed in: "Thank you for reminding us. I see that I need to work on a couple of those. I think constant scrolling and being alone too much can sometimes be linked together".

Carol Vorderman herself praised the insight, calling it "excellent advice".

For tailored health guidance, it's always best to consult your GP.
