Biohacking habits that I think are overrated

What’s worth the hype and what isn’t…

You know I love a good wellness gadget, especially when it actually helps you feel better. I’ve tried a lot over the years – some were gamechangers, others… not so much.

There’s so much noise in the biohacking world right now that it can feel like you need a $10,000 setup just to have decent energy or sleep through the night. Spoiler alert: you don’t.

Here are some biohacking products (and trends) that I think are totally overrated – and what to do instead for real, sustainable results.

(worth mentioning here that my fave Lumebox and castor oil pack are not overrated)

Biohacking habits that I think are overrated

1. Taking a Million Supplements “Just Because”

If you’ve ever looked at someone’s supplement shelf and thought, “Should I be taking more??” –  you’re not alone. But loading up on random pills without a clear reason can burden your liver, drain your wallet, and possibly make symptoms worse.

Many of us are taking things our bodies don’t even need – or can’t absorb properly – because we saw someone on TikTok recommend it.

Try this instead:

Get functional testing done first. This could include minerals, gut health, inflammation, hormones, and food sensitivities. I do this with my 1:1 clients, and it changes everything. You’ll save money and get better results by only supporting what your body actually needs. Testing removes the guesswork. If you’re interested in leanring more, email me gina@fitnessista.com subject TESTING.

2. Cold Plunges for Everyone

Cold plunges are everywhere right now. While they can have some benefits (like reduced inflammation and increased resilience), they’re not a fit for everyone, especially women dealing with hormonal imbalances, adrenal fatigue, or autoimmune flares.

If your nervous system is already running on overdrive, jumping into a tub of freezing water might just stress it out even more.

Try this instead:

Start slow. Try a short cold shower at the end of your warm shower, or finish with a splash of cold water on your face. Focus on nervous system regulation first – think breathwork, gentle movement, and prioritizing sleep. Then, if your body feels ready, gradually introduce cold exposure. Also heat exposure, like my beloved sauna blanket, can be a much better fit!! I WAY prefer heat over cold.

3. Super Pricey PEMF Devices with Wild Claims

I love PEMF therapy and use the HigherDOSE GO Mat regularly – it’s part of my morning routine. But some of the extremely expensive PEMF mats on the market promise everything from total healing to “reprogramming your cells.”

Try this instead:

Find a well-reviewed, affordable PEMF device that fits your needs. Use it consistently and combine it with other healing tools like red light therapy, grounding, or journaling. It’s not about the fanciest device; it’s about your habits. Use FITNESSISTA15 for 15% off HigherDose!!

4. Nootropic Blends with Zero Research

These “brain-boosting” powders and capsules might look cool on your shelf, but many are full of proprietary blends and stimulants with little actual research behind them. Plus, if you’re already running on low sleep, I hate to say it, but a mushroom powder isn’t going to fix it.

Try this instead:

Support your brain naturally: get sunlight in the morning, eat healthy fats, and try whole-food-based adaptogens like lion’s mane, L-theanine, or magnesium threonate from reputable brands. Real energy starts with foundations: sleep, blood sugar balance, and hydration.

5. Blue Light Glasses… All Day Long

Blue light blockers at night are super helpful. But wearing orange glasses all day? Not helpful. Your body needs blue light in the morning and early afternoon to support energy, alertness, and circadian rhythm regulation.

Try this instead:

Expose your eyes (no glasses or contacts) to natural light within 30 minutes of waking. Even 5–10 minutes outside helps set your circadian rhythm, support cortisol balance, and improve your sleep later that night. For the best blue light blockers that you can use all day (just swap the lenses), I highly recommend Vivarays (code FITNESSISTA).

6. Sleep Trackers That Stress You Out

I’ve used a few trackers over the years, and here’s the truth: if it’s causing more stress or making you obsess over your “sleep score,” it’s probably not helping. Sleep is about more than data; it’s about how you feel.

Try this instead:

Track how rested you feel each morning and focus on creating a bedtime routine you actually look forward to: magnesium, stretching, a book, or the sauna blanket. Trust your body more than your app.

7. $7,000 Cold Plunge Tubs

I’ll say it again for the people in the back: you do not need a luxury ice bath to get the benefits of cold exposure. Cold therapy is amazing, but a daily 60-second cold shower works just as well (and costs exactly $0)

Try this instead:

Use what you’ve got. A bowl of ice water for your face, a cold rinse after your shower, or a DIY cold bath in the tub with some ice packs from the freezer. Bonus: it builds resilience and can support the vagus nerve.

Friendly reminder:

Biohacking is not about doing everything or having all the fancy tools; it’s about being intentional with your habits, your energy, and your health.

If something feels like it’s adding stress, draining your wallet, or creating confusion… it’s probably not helping.

Start with the basics:

Quality sleep

Real food

Nervous system regulation

Functional testing

Movement you love

Morning light

Mindful stress support

The most powerful biohacks are simple, consistent, and sustainable.

Let me know if you’ve tried any of these trends or if there’s one you’re curious about – I’m happy to test things so you don’t have to. 😉
