Socialising can boost your immune system and increase life expectancy, according to a leading doctor.<\/p>\n

In an age of longevity clinics and ‘biomaxxing’ influencers like Bryan Johnson\u2014who has spent millions of dollars on trying to live longer\u2014immunologist Dr Jenna Macciocchi says that a long life doesn’t have to cost a thing.<\/p>\n

Instead she says that a simple lifestyle change can help prevent illness, and it’s as simple as enhancing your social interactions.<\/p>\n

This is because it boosts the immune system\u2014the body’s defence against infections\u2014and in\u00a0the longer term, it can reduce inflammation, a process linked to multiple diseases.<\/p>\n

Dr Macciocchi, author of the bestselling Immune to Age book which\u00a0outlines her hacks to live longer, said: ‘I think humans have this idea where if you’re paying money it therefore must work\u2014the thinking that says: “I’m taking 20 supplements so I’m good\u2014it doesn’t matter that I feel really wired and stressed out all the time.”<\/p>\n

‘But our immune system is the single greatest arbiter of both how long we live and the quality of those years.’<\/p>\n

The immunologist says people like billionaire Bryan Johnson are leading people in the wrong direction when it comes to trying to live longer\u00a0<\/p>\n

One of the tricks Dr Macciocchi says is the key to a longer and happier life is social interaction\u2014particularly for people over the age of 60.<\/p>\n

‘Focus on socialising, connection, and finding joy in the small moments\u2014that is all good for the immune system,’ Dr Macciocchi, told the I paper<\/a>.<\/p>\n

‘If you’re stressed, it puts your immune system on red alert\u2014primed for inflammation. If your thought patterns are calm and relaxed and you have a social connection.’<\/p>\n

On the Happy Place podcast with Ferne Cotton Dr Macciocchi explains this is because of the ‘mind body connection’ \u2013 or the psychoneuroimmunology.<\/p>\n

‘The immune system is not in one place in the body, it is everywhere,’ says Dr Macciocchi.<\/p>\n

‘Particularly with the brain, if you see danger with your eyes, that is information that your brain is taking and making an imprint of hormones it puts out into the body your immune cells pick up the signal and get ready for a threat,’ which increases inflammation according to the doctor.<\/p>\n

One of the key hormones for improving the immune system is oxytocin\u2014the love hormone.<\/p>\n

Oxytocin, also known as the ‘cuddle hormone’, is released by the body during ‘tender moments’ – including while hugging and during sex.<\/p>\n

\"Social <\/p>\n

Social interaction is the key living longer according to\u00a0Dr Macciocchi<\/p>\n

Immune cells have receptors for oxytocin, which is why the doctor believes that it holds the key to a longer happier life.<\/p>\n

‘What you are thinking and feeling directly impacts your immunology,’ says Dr Macciocchi. ‘I am safe, I am loved, these are really key feelings.’<\/p>\n

‘The oxytocin that’s released is calming and anti-inflammatory.’<\/p>\n

The doctor explains that online interaction is not enough to feel the benefits of socialising.<\/p>\n

‘There’s something about the physical contact\u2014your heart is electromagnetic\u2014eventually your heart beats will synchronise when you’re spending time with other people,’ says Dr Macciocchi.<\/p>\n

‘It is why you want to hug a friend, it is why you want to meet with people in real life and have that physical connection. Co-regulation we have is really physical. It’s great that we have technology but there is this fundamental thing we can’t replace.’<\/p>\n

Dr Macciocchi also says rather than considering it only when we’re unwell, we ‘have to think of it as a companion across the decades \u2013 befriend it and understand it early in life.’<\/p>\n

Her other tips include lift weights and limit takeaways in your 30s, destress in your 40s and 50s while focusing on remaining active in your 60s.<\/p>\n
