The celebrity wellness craze: Do these trendy health hacks actually work?

Professional athletes like LeBron James and Cristiano Ronaldo swear by cryotherapy, and sure, if you freeze yourself long enough, you might start feeling like a hardcore athlete too—minus the million-dollar contracts and six-pack abs.

Cryotherapy involves brief stints in extremely cold temperatures, ranging from -100°C to -180°C. Fans claim it reduces inflammation and speeds up muscle recovery, but the scientific evidence supporting these claims is limited, particularly regarding long-term effects. Potential risks, such as frostbite and other cold-related injuries, should be carefully considered.

Influencers and celebrities like Kourtney Kardashian have helped make reproductive health gummies the latest wellness “must-have,” promising everything from balanced hormones to improved fertility and regular menstrual cycles.

Packed with vitamins like folic acid and vitamin D, plus the occasional probiotic or herbal superstar like chaste berry, these gummies sound like a magic fix for all things reproductive. But before popping one like candy, remember: no gummy is going to single-handedly solve any health issue.

The diabetes medication Ozempic (semaglutide) has become the latest weight-loss wonder drug, partly thanks to celebrities and influencers who swear by its slimming effect. In fact, it’s become so mainstream that no awards show seems complete without the host making a joke about Hollywood stars’ dependence on it. Ozempic’s cousin, Wegovy, also contains semaglutide and is approved for chronic weight management, so it’s not just a celebrity trend—it’s also a real drug.

Both medications work by regulating blood sugar and curbing appetite, showing significant results in clinical trials. However, healthcare experts warn against using them without medical supervision. Common side effects include nausea and vomiting, with potential long-term risks that remain under investigation.

While the promise of quick weight loss is tempting, these medications should only be used under the guidance of a healthcare professional.

Nicotinamide adenine dinucleotide (NAD+) has gained attention in wellness circles, with celebrities like Gwyneth Paltrow and Hailey Bieber speaking about its potential to combat aging, boost energy, and improve cellular health.

NAD+ is a coenzyme found in all living cells, playing a crucial role in metabolism and DNA repair, which are your body’s backstage crew for staying energized and youthful. Early research, mostly in animals and lab settings, suggests that boosting NAD+ could support metabolism and fight some aging effects. However, human clinical trials are limited, and the long-term effects and appropriate dosages remain unclear.

Healthcare professionals recommend caution with NAD+ supplements, emphasizing the importance of evidence-based practices over unproven trends.

Biohacking, made famous by people like Elon Musk and Joe Rogan—and taken to an extreme by Bryan Johnson—is all about pushing your body and mind to their absolute limits. From mainstream methods like wearing gadgets to track your sleep and heart rate to more extreme tactics like taking nootropics (a.k.a. brain-boosting pills) or implanting devices to monitor every move, biohacking aims to optimise physical and mental performance using technology and scientific techniques.

While practices like tracking sleep and blood glucose are grounded in science, others—particularly those involving unregulated supplements or DIY genetic modifications—carry significant safety risks. Experts recommend focusing on evidence-based strategies and caution against experimental methods that lack robust scientific support.

With testimonials from figures like Hugh Jackman and Jennifer Aniston, intermittent fasting (IF) has become a popular dietary plan. 

Scientific research does back up some of IF’s potential benefits, like weight loss and improved metabolic health, including better insulin sensitivity and reduced heart disease risk. But let’s be clear: it’s not a magic wand. IF isn’t for everyone—especially those with diabetes or eating disorders. Even for healthy folks, sticking with IF long-term can be a challenge due to lifestyle factors and the occasional side effects like fatigue and a tendency to snap at your phone for not opening fast enough. 

It’s always a good idea to consult a healthcare professional or registered dietitian before diving into any fasting plan, just to make sure it’s the right fit for your health and not just another post-worthy trend.

Celebrities swear by hiking as the ultimate workout for shedding pounds and finding inner peace. From Reese Witherspoon trekking through Malibu’s scenic trails to Jason Momoa scaling rugged mountains, hiking is being hailed as the secret to staying fit.

Sure, walking uphill for hours will burn calories, but let’s not forget the A-list version often includes a personal trainer, a private trail, and a drone for that perfect Instagram shot. Still, the fresh air and cardio are hard to argue with.

While some celebrity wellness trends have a basis in science, others are more about marketing than proven results. Before trying any of these routines, consult trusted healthcare professionals to determine what truly suits your needs.

Are these practices groundbreaking or just another lifestyle trend? The reality often lies somewhere in between.
