A survey conducted for Herbalife found that one in five British adults aged 18 to 29 believe babies born today could live up to 150 years. To extend their lives, many young people are experimenting with extreme wellness practices such as ice baths and "sleepmaxxing." The study included over 2,200 participants across four generations, revealing that Gen Z spends significantly more on nutrition and health supplements compared to other age groups. Additionally, social media platforms like TikTok and YouTube are major sources of inspiration for these longevity trends among young adults.

One in five young adults think babies born today could live to 150 and many are already experimenting with ice baths, extreme fasting and 'sleepmaxxing' in a bid to extend their own lives.

many → think → lives
The survey of more than 2,200 British adults, carried out for the nutrition company Herbalife, found that six in ten (61 per cent) of Gen Z, defined in the research as those aged 18 to 29, are actively taking steps to improve their health with the specific aim of living longer.

ten → carry → aim
Almost two in five (38 per cent) would choose to live forever if science made it possible, compared with just 15 per cent of Baby Boomers, aged 62 to 80.
asserted
it → choose → Boomers
And 44 per cent of Gen Z said they would want to know the age at which they will die, more than twice the proportion of Boomers (19 per cent).
asserted
they → say → Boomers
The research divided adults into four generations: Gen Z (aged 18 to 29, born roughly between 1997 and 2008), Millennials (30 to 45, born roughly between 1981 and 1996), Gen X (46 to 61, born roughly between 1965 and 1980) and Baby Boomers (62 to 80, born roughly between 1946 and 1964).

research → divide → 1946
Young people are also putting their money where their mouth is.
asserted
mouth → put → money
Gen Z spend an average of £111.90 a month on nutrition, exercise, supplements and alternative wellness therapies, 11 per cent more than Millennials and 39 per cent more than Boomers.
asserted
Z → spend → Boomers
Ice baths are among the strategies Gen Z are turning to in a bid to add years to their lives
asserted
Z → turn → lives
The youngest adults are far more likely than older generations to try newer longevity trends.
asserted
adults → try → trends
One in five (21 per cent) have tried ice baths or cold-water therapy, compared with just 1 per cent of Boomers.
asserted
One → try → Boomers
Some 15 per cent have tried 'sleepmaxxing', optimising their sleep through strict routines, tracking and other techniques, while 13 per cent follow personalised nutrition plans.
But when it comes to more traditional habits, older generations lead the way.
asserted
generations → try → habits
Gen X are the most likely to take supplements regularly (39 per cent), followed by Millennials (36 per cent), while only a quarter of Gen Z and Boomers do so.
asserted
quarter → take → Z
Overall, supplements were the most popular longevity habit among Britons, used by 31 per cent, followed by fitness or health-tracking devices (21 per cent) and intermittent fasting (11 per cent).
asserted
supplements → use → devices
Almost half (47 per cent) of Britons said they would take a daily pill or supplement if it could give them another 20 years of life.
uncertain
it → say → life
Gen Z are also paying close attention to their diets.
asserted
Z → pay → diets
Almost a third (30 per cent) follow a high-protein diet, while nearly a quarter (23 per cent) track their calories, macros or nutritional intake, and the same proportion practise mindful or intuitive eating.
asserted
proportion → follow → eating
Among Gen Z who have tried wellbeing practices, 37 per cent were inspired by TikTok and 32 per cent by YouTube, compared with 27 per cent who took inspiration from friends and 20 per cent from family.
asserted
who → try → family
More than a third (35 per cent) said they trust the healthy ageing advice they see on social media, yet almost half (46 per cent) said it puts them under pressure to maintain a youthful appearance.
asserted
it → say → appearance
Beneath the enthusiasm lies a deep fear of ageing.
asserted
fear → lie → ageing
Almost half of Gen Z (49 per cent) admitted they are afraid of getting older, and 45 per cent are afraid of looking old.
asserted
cent → admit → Z
More than a third (36 per cent) said they were more worried about looking old than feeling old, compared with just 16 per cent of Boomers.
asserted
they → say → Boomers
Dr Richard Allison, a nutritionist at Herbalife and former head of performance nutrition at Arsenal FC and Tottenham Hotspur Women's FC, said: “It's exciting to see younger generations taking such a proactive approach to their long-term health and wellbeing, and embracing new ideas around longevity.
“
asserted
generations → say → longevity
However, while emerging trends like biohacking and recovery therapies are gaining attention, the foundations of a long and healthy life remain consistent – regular movement, balanced nutrition, quality sleep, targeted supplements, and sustainable daily routines.
asserted
foundations → emerge → life
“The key is finding an approach that blends innovation with these proven basics, creating habits people can realistically maintain over time.”
asserted
people → find → time
Opinium surveyed 2,223 UK adults, including a boosted sample of 500 Gen Z adults, between 31 July and 5 August 2026.
