Future-proof your body: Beginner biohacks that could add years

If you’ve paid attention to health and wellness culture, you’ve likely encountered the word “biohacking” at least once. The term can mean different things to different people, but the gist is this: Making small but strategic tweaks to your health to help you live a longer, healthier life.

For some, “biohacking” is all about tech, with an emphasis on data, wearables like Whoop or the Oura Ring, and specialized equipment like sleep-tracking beds or . But many people can achieve their desired goals with simple changes to habits related to sleep, fitness, diet, and stress management.

Still unsure what biohacking is? broke the term down into various categories—sleep, exercise, diet, microbiome health, meditation, hot and cold therapy, and supplementation—and asked health experts across disciplines to share their insights and recommendations.

Easy “Biohacks” Anyone Can Do

1. Optimize sleep

You probably know that getting enough high-quality sleep is crucial for overall health and well-being. But you might not realize just how important it is. Poor sleep is linked to , , , , , and , and can reduce the risk of all.

Fixing your sleep won’t happen, well, overnight, and it will likely require more than one little hack. A good place to start: getting your back in sync, says functional medicine physician Jeffrey Egler, M.D.

“To optimize sleep, you want to ,” Egler says. Dim or turn off any bright or overhead lights, which make the brain think it’s still daytime and limits .

from our devices has the same effect. Turn off screens two hours before bedtime, Chelsea Perry, D.M.D., says. Sure, you can try setting your phone to night mode or wearing blue light-filtering glasses, but �ٳ󲹳�’s only half the battle.

“Think about what you’re looking at,” she says. “Are you reading the news? Are you scrolling? Your brain is probably too engaged to be getting into a good sleep pattern.”

Other from our experts:

• close to bedtime.
• . Its shelf-life is 5 to 6 hours but it can linger in the body longer, so it can still affect sleep hours later.
• .
• Take a hot shower before bed to lower your core body temperature and signal that it’s time for sleep.

2. Focus on Zone 2 training

HIIT, while still beneficial for some goals, had its moment in the spotlight, but experts say intense workouts can lead to , which , , and .

As a result, biohackers have largely shifted to a gentler form of fitness for overall health, longevity, endurance, and : Zone 2 (60 percent to 70 percent of your max heart rate) training.

It may seem counterintuitive, but exercising at a lower intensity for longer can improve endurance and . “The more intense your exercise, the more carbohydrates or sugar you burn,” Egler says. “When you’re doing an activity less intensely, you are more in a .”

Most can be done in Zone 2, including , , , , , and the . Once you determine your Zone 2 range, a smartwatch or other wearable can help you stay within it.

Regardless of the exercise, make time to recover. “The biggest secret across all of exercise is you need enough , either a complete day off or in some cases two at a , to be able to go hard,” Bob Arnot, M.D., says.

3. Never stop strength training

is crucial for getting stronger and maintaining muscle mass and mobility as we age.

“Strength training is vital for preventing frailty and , which directly supports your ,” Arnot adds.

Egler says strength is one of the two main —the other being a healthy percentage of .

and , HIIT classes that incorporate strength training, traditional gym lifts—whatever you like to do, do it, Egler says. Just make sure you’re doing it regularly.

“Most recommendations are to do strength training ,” he says. “I don’t think �ٳ󲹳�’s enough. I think it should be done most days of the week, rotating different parts of the body.”

Egler recommends that you also throw some and in to help prevent falls and .

4. Build a supplement stack

The body needs , minerals, and other essential nutrients to function at its best, but the jury is still out on whether supplements are the best way to get them.

There’s no shortage of on the market, from a to a , , and potions. While they’re easy to buy over-the-counter, it can be hard to know what you truly need without consulting a healthcare provider. Plus, supplements also have potential side effects and drug interactions, just like other medications.

If you have a legitimate or , you might need some extra help. A simple boost of a particular vitamin can make a big difference—if you know what to take.

Symptoms may have several root causes, so it’s a good idea to ask your doctor for a to look for or , , or . This avoids a scattershot approach to a supplement stack that falls short or causes more harm than good.

5. Start meditating

has lots of immediate and downstream benefits for physical and mental health. Research has found it can improve sleep, , , , , and .

Even better, it doesn’t require any special gear or gadgets and takes minutes to work.

If you’re resistant to meditating because you think you won’t be able to do it properly, the key is just to start. Even 5 minutes (or less) has major mind and body benefits. Once you’re comfortable, gradually work up to longer lengths of time for even greater benefits.

For some, following a guided meditation on an app like Headspace or Calm can get you more comfortable with the process.

Tom Ingegno, D.A.C.M., M.S.O.M., L.A.C., says can also be a form of meditation, especially when paired with , as in yoga, tai chi, and Pilates.

6. Use the sauna

has several benefits for both physical and mental health, including and .

in JAMA Internal Medicine found that regular sauna use (defined as four to seven times per week) reduced all-cause mortality by 37 percent due to the practice’s effect on heart and blood vessel function.

All of that heat and serves as what’s known as a mimetic or “passive” exercise. “It makes your body think you’re doing cardio,” Ingegno explains.

The key is to sweat, Ingegno says. Finnish-style “dry” saunas or steam saunas usually get between 160 degrees Fahrenheit and 200 degrees Fahrenheit, though in gyms and other public spots, they’re usually capped at 180 F. Infrared saunas use a lower temperature of about 140 F, so you can stay in them longer.

A communal steam room or sauna works just fine. There are also plenty of options if you’ve got the space and the cash to do so. They range from single-person pop-up sauna tents for indoor use for just a few hundred dollars to multi-person outdoor barrel saunas for several thousand dollars. Infrared saunas are typically more expensive than Finnish or steam saunas.

7. Track everything

The research isn’t conclusive, but some studies suggest that is associated with increased physical activity and weight loss.

It can help in other health areas, as well. For example, Egler says tracking his sleep by wearing his Apple Watch helped him notice patterns that spurred him to get evaluated for sleep apnea.

Arnot tracks various metrics with various devices. “I have my so I know my second-by-second blood sugar,” he says. “I have my Whoop device to track my overnight HRV and my recovery . And then I have my Garmin Epix Pro, which has all my workouts, my heart rate, and my strain.”

There’s no shortage of wearables to track virtually every health metric: steps, sleep, heart rate recovery, , and more. Here are a few of our recommendations:

• : Most wearables go around the wrist, but Oura is worn on a finger. It measures sleep, stress, movement, heart rate, heart rate variability, and blood oxygen.
• : Nearly as ubiquitous as the iPhone, Apple Watches track various health and fitness metrics, including steps, heart rate, irregular heart rhythm, noise levels to protect hearing, workouts, and sleep.
• : These track sleep, vitals such as skin temperature and heart rate, and behaviors you can input yourself, like caffeine consumption and sunlight exposure.
• Garmin: A favorite of runners and athletes, Garmin can track , ECG, hydration, sleep, and also determine your fitness age.
• FitBit: Now owned by Google, the standby is available in a variety of models that track workouts, calories, heart rate, stress and sleep.
• Muse: Ingegno is an ambassador for the Muse headband, which tracks your brain activity during meditation and sleep to help improve focus.

7. Upgrade your diet

Even though there’s not a single diet �ٳ󲹳�’s been deemed The Best (though the comes pretty close), there are some aspects both experts and research can agree on: , , and .

Different diets are popular with biohackers: , , , and to name a few. Their clear boundaries may appeal to biohackers, but can be hard to stick with over time.

Instead, rather than what you’re removing. Both Egler and Arnot recommend a diet composed of �ٳ󲹳�’s , like line-caught salmon. Still, Egler recommends removing the two basic baddies: .

8. Take a cold plunge

Emerging evidence supports and in general for physical and mental health. One small 2023 study found that 15 minutes of cold-water immersion at 50 F (10 degrees Celsius) lowered negative thoughts and levels of the after 3 hours.

Other research suggests it may , and , , and .

works through a process called hormesis. “Hormesis is stressing the body a bit to encourage a positive outcome or healing response,” Ingegno says. When we cold-plunge, we stimulate cold-shock proteins. “They help the body protect itself,” he adds.

To try it, “dip a toe,” recommends Ingegno, in the figurative sense. “Start slowly, with short exposures. The easiest, cheapest way is cold showers.”

If you want to go full immersion without committing to a just yet, you can simulate the experience by in your bathtub with a bag of ice and cold water. Ingegno’s practice offers cold plunging to its clients, so you might also be able to try it at an integrative practice, gym, or wellness center near you. And remember: Have plenty of warm, dry clothes on hand to prevent hypothermia.

9. Optimize your microbiome

Most of the microbiome is housed in our large and small intestines, and keeping it healthy and balanced is crucial for . This is important for , as it’s linked to many diseases, including cancer and cardiovascular disease.

Newer research looks into : the waste left behind by gut bacteria after they feed on prebiotics. This stuff is good for the body, too: Postbiotics can include key vitamins, , and short-chain fatty acids.

Tons of supplements aim to : prebiotics, (which add more good bacteria), and synbiotics (a combo of the two). Your physician can order a blood or stool to better understand what’s going on.

The general recommendation is to eat first and supplement second. Egler says that if you only supplement without changing your diet, you won’t get the results you want.

include whole-grain foods, garlic, asparagus, and bananas. Probiotics are foods that contain live organisms such as yogurt, sauerkraut, kimchi, and kombucha.
