When your bedroom won't drop below 28°C, sleep becomes almost impossible. Most of Europe isn't built for heat, and installed AC is rare. Here are twelve things that genuinely help you sleep in a heatwave — starting with free tricks, then the cheap gear that makes the biggest difference.

## Free tricks (do these first)

- **Close blinds and windows during the day.** Keep the hot afternoon air and sun out; only open up once it's cooler outside than in (usually after midnight).

- **Create a cross-breeze at night.** Open windows on opposite sides of the flat to pull cooler night air through.

- **Cool your pulse points.** A cold, damp cloth on wrists, neck and ankles lowers how hot you feel fast.

- **Take a lukewarm shower before bed** — not cold, which makes your body generate heat afterward.

- **Ditch the duvet; use a thin cotton sheet** and swap synthetic bedding for breathable cotton or linen.

- **Freeze a water bottle** and place it by your feet, or a damp towel in the freezer for 20 minutes.

- **Sleep low.** Heat rises — a ground-floor room or even a mattress on the floor is cooler.

## Cheap gear that makes the biggest difference

If the heat is going to last, a small purchase can turn a sleepless night into a bearable one.

- **A quiet tower or pedestal fan (from ~€30)** is the single best value. Moving air over your skin dramatically lowers how hot you feel. Point it across your bed, not directly at your face, and place a bowl of ice in front of it for a DIY cool breeze. See tower fans on Amazon.de →

- **An evaporative air cooler (from ~€60)** blows air chilled by evaporating water — great in dry heat, no window kit needed. See air coolers →

- **A dehumidifier (from ~€120)** if your room is muggy — dry air feels noticeably cooler and helps you drop off. See dehumidifiers →

## When only real AC will do

If you're in a heat pocket where fans just aren't enough, a portable air conditioner is the only no-installation option that actually lowers the temperature. It's a bigger spend (~€250+) but it's the difference between sleeping and not. See our [portable AC buying guide](https://getecoback.com/en/guide/best-portable-air-conditioner-europe-heatwave.html) to pick the right size.
