From chilly plunges to steady glucose screens, these 5 high wellness tendencies of 2025 have taken the world by storm. However do they actually supply significant longevity advantages?
Today, everyone seems to be looking out for the subsequent sorcerer’s stone — a easy reply that stops getting older in its tracks and allows us to reside longer, more healthy lives. From intermittent fasting to chilly water plunges, there’s been a good quantity of bandwagoning in wellness circles concerning these “wholesome” practices.
However whereas some habits do certainly promote longevity, others could not have the advantages some snake oil salesmen declare. Even worse? A few of these fads could even be chopping down your lifespan, particularly in the event you’re a lady.
So which habits do you have to cling to and which ought to be part of low-fat diets and sugar-free soda within the pile of outdated tendencies? And do any of those tendencies really unlock the right way to reside longer? Right here’s what the specialists must say about at this time’s hottest wellness tendencies.
1. Intermittent Fasting
The advantages of intermittent fasting, from improved coronary heart well being to decreased irritation and weight reduction, are effectively documented. A 2021 research in Nature Growing old confirmed that fasting might scale back mobile getting older and mitigate the chance or signs of autoimmune issues, neurodegeneration, metabolic illness, and even most cancers1. The one downside? The overwhelming majority of those research have been carried out on mice or males — and for girls, it’s a complete totally different ball recreation.
A 2012 research in Weight problems Analysis discovered that ladies with a wholesome physique weight who start alternate-day fasting might expertise impaired glucose response2. Equally, a 2022 research in Weight problems discovered that ladies fasting for between 18 and 20 hours a day skilled on common a 14% drop in DHEA (a hormone that helps estrogen manufacturing) over the course of eight weeks3.

“There was no important drop in estrogen through the course of the research, which is sweet information,” says cognitive neuroscientist Therese Huston, Ph.D., writer of Sharp: 14 Easy Methods to Enhance Your Life with Mind Science, who was not concerned within the research. “But when ladies have been doing time-restricted consuming long-term, for a yr, let’s say, that drop in DHEA might have an effect on their hormone manufacturing.”
Dave Asprey, 4x NY Occasions Bestselling Creator of Closely Meditated, agrees. “In the event that they’re not getting sufficient restoration or sufficient meals, their our bodies will freak out and say, ‘No, it’s not protected right here. We don’t have sufficient sources to make a child,’” he says. “Because of this, your reproductive system shuts down and also you’ll really feel anxious on a regular basis. That’s not nice for longevity.”
Nonetheless, Asprey notes that ladies can nonetheless reap the advantages of intermittent fasting, albeit with a number of tweaks. He recommends that ladies be “gentler with their fasts,” fasting 3 times every week somewhat than every day, and for 12 hours somewhat than 16.
2. Chilly Water Publicity
Chilly water plunges have been common in Nordic cultures for generations, and for good cause. Trendy science confirms that the well being advantages of chilly water immersion embody decreased irritation and improved resiliency4.
Nevertheless, Huston cautions that sure folks, similar to these with coronary heart circumstances, should be significantly cautious earlier than embracing this apply. And as with intermittent fasting, ladies may need to take a much less excessive strategy to reap the chilly plunge advantages.

“Train physiologist Dr. Stacey Sims has identified that ladies typically reply otherwise to excessive chilly than males do,” she says. “In very chilly circumstances, assume ice tub, ladies typically expertise the excessive stress ranges with out the shivering that stimulates metabolic advantages like glucose tolerance.”
Instead, Huston cites analysis that appears to point that 60-degree plunges could be useful for girls5. “After this type of average chilly water swim,” she says, “ladies typically report decrease ranges of tension and melancholy and revel in higher sleep, whereas older ladies typically report fewer sizzling flashes.”
3. Steady Glucose Screens
Steady glucose screens (CGMs) are all the craze in the meanwhile, and never simply amongst folks with diabetes. These screens supply customers real-time insights into glucose fluctuations, which some specialists have deemed “the final word biohack6.” And since some research present that glucose dysregulation could also be extra widespread amongst wholesome folks than beforehand thought, it’s no shock that many are leaping on the CGM bandwagon7.
“Steady glucose screens are completely helpful for longevity,” says Asprey. “They’ll establish which meals work along with your biology and which of them don’t. They’ll additionally assist establish glucose management points so you’ll be able to deal with them lengthy earlier than they turn into an issue. Diabetes will increase your danger of heart problems, most cancers, and Alzheimer’s. These all scale back life expectancy. You need to be certain your physique is metabolically versatile and capable of make the most of glucose successfully.”

However, some specialists consider these screens can introduce extra stress than they relieve. “Steady glucose screens could be a life-saver for people with diabetes, however for the common wholesome particular person, it’s extra fad than fabulous,” says Huston. In a single research of 153 non-diabetics, glucose readings have been regular 96% of the time, with most of the spikes attributed to sensor errors8.
“Principally, in the event you’re wholesome, your physique retains sugar in examine by itself, with out the necessity for an costly gadget,” she says. “It’s a enjoyable curiosity, little doubt, and for individuals who love knowledge, it’s in all probability extremely satisfying to see what their avocado toast did to their blood sugar, however for wholesome people, it’s not going so as to add years to your life.”
4. Full Physique Scans
We by no means actually have a full image of what’s happening inside our our bodies, which in keeping with the Wall Road Journal, is a part of the explanation why full physique MRIs and different scans have turn into common amongst sure rich well being nerds9. Asprey, for one, is an enormous fan.
“In case you have the finances, full physique MRIs like Prenuvo change lives,” he says, noting that one in each 20 scans identifies “a probably life-saving analysis.” However as Scrubs confirmed us again in 2004, more often than not, these scans are costly methods of inviting much more anxiousness about your well being10.
“These scans look like they’ll give you unbelievable insights into your physique, however for wholesome people, they typically introduce extra issues than options,” says Huston, who notes that the potential for “false alarms or false positives” is excessive.

“The scans detect one thing small, the individual then worries and does a cascade of checks and biopsies, typically invasive and probably painful, simply to study it was nothing, or at the least utterly benign, in the long run,” she says.
And since these scans usually price a number of thousand {dollars} — and aren’t coated by insurance coverage — they might simply be an costly headache. “It’s a lot wiser to spend your money and time on issues which might be confirmed to be health-promoting, like preventative screenings, common check-ups, and train,” she says. “My recommendation? Spend the cash you’d have spent on a scan on a health club membership.”
5. Excessive Diets
Diets eliminating every thing from carbs to gluten to animal merchandise have turn into par for the course. However in keeping with our specialists, adhering to an excessive food plan could trigger extra issues than options.
“One fad that issues me are the all-carnivore diets,” says Huston. “The all-carnivore food plan, which includes solely consuming meat, hasn’t been correctly studied to show that it’s protected.”

Asprey, in the meantime, is crucial of the other. Whereas analysis appears to help the view {that a} plant-based food plan could contribute to decreased danger of diabetes, diverticular illness, and cataracts, research additionally present that vegans have the next danger for fractures11. Asprey believes that the dearth of bioavailability of sure nutritional vitamins and minerals in plant meals, compounded with the presence of anti-nutrients like lectins, oxalates, and phytic acid, might result in deficiencies.
It’s the extremity of both strategy that worries Huston. “Consuming just one form of meals creates nutrient imbalances,” she says, “and we don’t know the long run results of these imbalances.”
Most analysis reveals {that a} balanced omnivorous food plan just like the Mediterranean food plan is probably going the very best for longevity. A 2018 analysis evaluate in Present Opinion in Medical Diet & Metabolic Care encompassing 19 stories from massive potential research confirmed “with practically good consistency” that this food plan is more likely to scale back the danger of persistent illness and in the end enhance life expectancy12.
Remaining Ideas
Whereas there are definitely constructive outcomes that may be achieved from any considered one of these wellness tendencies, it’s smart to take all of them with a grain of salt. In the event you love an ice tub and really feel it has constructive results in your psychological well being, go for it! However be cautious of any fad that guarantees to be the important thing to longevity — the true secrets and techniques to dwelling a protracted and wholesome life are extra about consistency than a single golden ticket.
