Sleep: The Silent Reboot

Sleep is often the first sacrifice and the last priority in high-performance environments. But here’s the truth: if we’re serious about resilience, decision-making, learning, and recovery, sleep isn’t optional. It’s operational.

I felt this keenly during my PC-21 conversion. The days were long, the learning curve vertical.

My mind was crammed with checklists, radio calls, and flows. I knew that my recall, focus, and composure would crumble if I didn't protect my sleep.

So I treated sleep as a mission, just as essential as the sortie itself.

What Happens When We Sleep?

Sleep isn’t just rest—it’s recalibration. While we sleep:

• Our brain consolidates learning and motor skills (checks and cockpit procedures!).

• Stress chemicals like cortisol are metabolised and reset.

• Cellular repair and hormonal regulation ramp up.

• Emotional reactivity is dialled down, improving judgement.

Just one poor night of sleep and the impact can be clear. String a few together, and our reaction time, memory, and emotional control start to slide.

In Defence, that’s not just inconvenient—it’s dangerous.

Tactics to Improve Sleep (Even in High-Tempo Environments):

1. Consistent Timing Wins:

Try to anchor wake time, even if bedtime fluctuates. This stabilises our circadian rhythm and improves sleep depth.

2. Control Light Exposure:

Morning sunlight boosts alertness; turning off dim lights and screens one hour before bedtime helps melatonin function effectively.

3. Drop Our Core Temperature:

A warm shower before bed sounds backwards, but it actually cools our body by drawing blood to thesurface. This drop in core temperature helps signal sleep readiness.

4. Mental Downshifting:

Our minds can loop in high-pressure cycles (like preparing for a flight). Try pen-and-paper journaling to offload thoughts and create cognitive closure before sleep.

5. Caffeine Cut-Off:

Everyone’s different, but a good rule: no caffeine after 2 pm. Stimulants block adenosine, the molecule that helps trigger sleepiness.

During my most intense prep week, I kept my sleep sacred. It wasn’t perfect—but it was prioritised. And that gave me an edge: quicker recall, steadier nerves, and better emotional recovery when the feedback stung.

Performance doesn’t happen despite sleep. It happens because of it.
