The Cool-Sleep Playbook

Most of these you can start tonight, for free. Do #1 and #7 first — they change the most.

1. Drop your bedroom to 18°C before you get in

Your core temperature has to fall for you to nod off. Set the aircon or fan to run before bed, not once you're already hot — you're helping your body do what it's trying to do.

2. Switch to breathable natural fibres

Bamboo, Tencel or linen sheets wick moisture away; polyester traps it against you. Same for sleepwear — loose and natural, or nothing at all.

3. Keep a “cool kit” on the nightstand

A small fan, a cold water bottle, a spare dry top. It won't fix the night, but it buys you a few minutes at 3am.

4. Cut the late-day triggers

Alcohol, spicy food and caffeine after about 2pm all raise your night-time body heat. Even a small change here shows up in your sleep.

5. Cool your pulse points

Wrists, the back of the neck, behind the knees — a cold compress there cools you faster than trying to fan your whole body.

6. Protect your wind-down

Screens and stress spike cortisol, which makes flushes worse. A dim, boring last thirty minutes genuinely lowers the odds of waking up hot.

7. Fix the surface, not just the room

This is the one that lasts. A gel pad or frozen bottle quits in about twenty minutes because it has no power source — your body heat wins every time. An actively-cooled mattress pad refrigerates your side of the bed and holds a steady temperature all night: cool at lights-out, still cool at 5am. It's the difference between a trick and a solution.
