Slick, spa-like spaces offering red-light therapy, hyperbaric oxygen and personalised IV infusions are popping up across the country, selling the dream of longer, healthier lives. But it comes at a price – sometimes in the hundreds of dollars.

And behind the futuristic treatments and influencer hype, experts say the science doesn’t quite stack up.

While some providers claim benefits like reduced inflammation, improved energy and even cellular regeneration, leading longevity physician Luigi Fontana says evidence is thin.

“There are no data,” he warns, pointing instead to a far simpler solution of reducing waistlines through diet and exercise.

This hasn’t stopped demand. Club founders say clients report life-changing results, and that social media is fuelling interest in so-called “biohacking”.

“I say to the cynics, medicine is changing and we really need to keep up with that,” said Sheena Burnell, medical director at TotalFusion fitness and wellness clubs. “Because the population is changing, people are changing.”

But public health experts remain cautious, warning of a powerful placebo effect and a growing industry built on it.

Because when it comes to living longer, the most effective prescription may still be the least glamorous: eat well, move more, and get a good night’s sleep.
