He revealed '5 things that could be ageing your brain'. By being aware of these habits, you can take steps to modify them and support brain health. According to Dr Khan, 'here are 5 everyday habits that are quietly ageing your brain':
1. Constant multitasking
"We think we are being productive, but jumping between tasks stresses the brain, and it can weaken short-term memory and increase our cortisol levels. Over time, that can affect our brain battery, which is linked to focus and emotional control," Dr Khan said.
2. Chronic sleep deprivation

2. Chronic sleep deprivation

3. Doom scrolling
"Hours of passive scrolling overstimulate the brain, trigger the stress response and reduce dopamine sensitivity, affecting memory and mood. Plus, the blue light exposure before bed impairs melatonin release, affecting deep sleep," he shared.
4. Skipping meals, especially breakfast
According to Dr Khan, "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."
5. No social contact
He added, "Social interaction is protective. A study shows loneliness is as harmful to cognitive health as smoking 15 cigarettes a day. Socialising boosts cognitive reserve and reduces dementia risk, even just chatting with a friend or neighbour. So, remember, keep your brain healthy by not doing these five things."
