How Stress Can Make You Stronger: A Biohacker's Top Tip For Mental Resilience

"OK, I officially don't feel my toes anymore," said the high school version of me, from the back of the open cargo truck transporting my squad of eight military sharpshooters. It was -30°C (-22°F) outside, we'd already been traveling for two hours, and there was about as much time left to go. Even worse, the wind was howling from all angles, and we could all feel the chill penetrating our bones.

By the time we arrived at our home for the week, none of us felt any better. We were staying in the pit of an abandoned strip mine with a stone floor and a wind tunnel. The temperatures were as unforgiving as -30°C and it even got down to -35°C at midnight. To make matters worse, we all had to do night patrol for at least an hour.

Sleeping in a tent with a small stove was the only time we could stop shivering and enjoy a brief moment of warmth.

During the day, we practiced sharpshooting by camouflaging (aka lying motionless in the snow and trying to crawl toward a target), measuring distances with binoculars, making landscape maps by drawing on a piece of paper, firing long distances, and so much more.

Through my time in the military, I discovered that life will throw countless challenges and obstacles at you. That's just how the world works, and there's nothing you can do about it. Eventually, something negative or difficult is going to happen.

While that information might seem daunting, I actually see it as empowering—because it means we can all proactively prepare and cultivate personal resilience.

How? By exposing ourselves to somewhat stressful and challenging situations on a regular basis. For example, I'm a major advocate of voluntarily training our nervous system and psychology with positive stressors, including exercise, sauna, intermittent fasting, meditation, breathwork, and cold exposure.
