4. Cultivate strong social connections

We know that good social bonds are the key to healthy ageing, and the science stacks up.

“Longevity studies, such as those around the blue zones [places in the world where there is a high incidence of centenarians, such as Sardinia and areas of Japan], show that having close relationships, community engagement, and a sense of purpose contributes significantly to our longevity,” says Dr Martin Thornton, chief medical officer at Bluecrest. “People with strong social ties and fulfilling daily activities tend to live longer, healthier lives.”

5. Schedule regular health check-ups

Once we hit a certain age (usually our 40s and 50s), we’re fortunate enough in the UK to be offered standardised screening programmes for some diseases, and it’s vital to keep up with these appointments.

“So much of our health is connected and conditions like high blood pressure, type 2 diabetes and high cholesterol can all affect brain health,” says Dr Thornton. “Routine check-ups help catch these early, so they can be managed before they impact your cognitive function.”

6. Lower your stress levels

Last but not least, try to keep a lid on your stress levels. It’s easier said than done, but long-term, chronic stress affects brain function and can increase our risk of developing certain conditions.

“We are living in a world that the human brain is not well-adapted to, and as a result we experience and normalise very high levels of stress,” says Dr Diamandis. “It’s more important than ever before to find ways to manage our stress and close the loop on the stress cycle daily, whether that is through exercise, creative hobbies, meditation or spending time in nature. Taking regular ‘brain breaks’ to do nothing, daydream and allow the brain to rest from constant stimulation is also vital.”
