Sleep is anabolic.
There’s a reason that night sweats are one of the most common signs of low testosterone in me.
Every night, your body initiates a biological power-down — dropping its core temperature by 1 to 1.5°C before entering deep sleep.
This isn’t random.
It’s how your brain signals: “It’s time to recover, reset, and rebuild.”
A colder body temp means:
- Faster sleep onset
- Deeper, more restorative sleep
- A surge in testosterone and growth hormone
But here’s the catch: your environment matters.
If you’re too warm, your body fights to cool down — and that fight costs you deep sleep and hormonal gains.
You end up trapped in a cycle:
High temperature, night sweats, Low T.
Your stained yellow pillow tells the story...
So if you're serious about maximising recovery, strength, and performance… maybe it's time to cool things down.
sleep kold.
