Cold plunges, nootropics, intermittent fasting, blue light blockers biohacking is no longer a fringe trend. It’s a growing wellness movement focused on optimizing your mind and body using science, data, and technology.
But with influencers touting extreme routines and controversial supplements, it’s fair to ask: how much of it is hype—and how much can actually help? Let’s explore the most popular biohacks of 2025 and what the research says.
1. Cold Exposure for Recovery and Alertness

2. Nootropics for Focus and Cognitive Edge
Nootropics, or ‘smart drugs,’ are brain-boosting supplements that claim to enhance memory, creativity, and mental stamina. Popular options include L-theanine, lion’s mane mushroom, and Rhodiola. Results vary, and more research is still needed.
3. Intermittent Fasting for Energy and Longevity
Time-restricted eating is one of the most widely practiced biohacks. Fasting windows (like 16:8) are linked to improved insulin sensitivity, metabolism, and even cellular repair.
4. Wearable Tech as a Feedback Loop
From heart rate variability to blood oxygen tracking, wearables like WHOOP and Oura offer the data needed to adjust your recovery, training, and sleep habits.
