1. Choose breathable bedding made from natural materials

Few things are more unpleasant than waking up sweaty under a blanket that traps heat. That’s why it’s best to go for bedding made from breathable materials like organic cotton, bamboo, or linen. These fabrics wick away moisture and feel airy against your skin, perfect for hot summer nights.

From experience, we know that bedding made from natural fibres can significantly improve sleep quality. At Tuur®, we use GOTS-certified cotton in our pillowcases, sheets, and duvet covers. A conscious choice for people who value both comfort and sustainability.

2. Sleep on a ventilating mattress with natural layers

A mattress is more than just a sleeping surface, it also plays a vital role in regulating your body temperature. Some mattresses trap heat, while others actively support airflow. Ideally, choose a mattress with open-cell structures and natural materials such as hemp, coconut fibre, or horsehair. 

The Tuur® Original Plus combines organic latex, hemp fibre, and horsehair. Three materials that promote optimal air circulation. Horsehair, in particular, is known for its ability to wick away moisture and regulate temperature, and it’s been used in premium mattresses for generations. 

The result? A bed that stays fresh and comfortable, even on the hottest nights.

3. Block sunlight during the day

A simple but often overlooked tip: close curtains or blinds during the day to keep heat from entering. Light-coloured blackout curtains reflect sunlight more effectively than dark fabrics. You can also apply heat-reflective window film on windows that get a lot of sun. 

By blocking direct sunlight, you prevent your bedroom from becoming an oven by evening. A well-insulated room, combined with smart shading, makes a noticeable difference.

4. Promote natural airflow (‘cross-ventilation’)

When the outside temperature drops, usually around sunset, it’s the perfect time to open your windows on opposite sides of the room or house. This creates a natural air current that pushes warm, stagnant air out.

Bonus tip: open interior doors and use a fan at low speed to enhance the airflow without creating a draft.

5. Use a fan with a cooling trick

A fan moves air but doesn’t actually cool it. You can boost its effect by placing a bowl of ice or a damp cloth in front of it. The airflow becomes slightly cooler and feels more refreshing. 

Just make sure the fan isn’t blowing directly on you while you sleep, as this can lead to muscle tension or even a cold.

6. Turn off unnecessary heat sources

Electronics like chargers, laptops, and lights can release a surprising amount of heat, even when not in use. Unplug them entirely before bed. In the evening, switch to LED lights, which emit less heat than conventional bulbs. 

The fewer heat sources you have in your bedroom, the easier it is for your body to cool down naturally.

7. Use cold cloths or socks to cool your body

Here’s a surprisingly effective trick: cool your body locally. Place a cold, damp washcloth on your forehead or ankles, or wear lightly moistened socks from the fridge. Your body cools faster through its extremities, which helps you feel sleepy more quickly. 

You can also use a hot water bottle, filled with cold water this time, and rest it on your feet or stomach as you drift off.

8. Adjust your evening routine to the season

Avoid heavy meals, alcohol, or intense workouts just before bedtime. These can raise your body temperature. Instead, take a lukewarm shower (not ice cold, which can have the opposite effect) and wear loose, breathable sleepwear. 

Routine is important for your body’s natural rhythm. By aligning your bedtime habits with warmer weather, your body can ease more gently into sleep.

9. Sleep in a cooler room if possible

Heat rises. If you have a basement or a north-facing room, consider switching sleeping locations during a heatwave. A flexible mattress, like a latex mattress without metal coils, is easy to move and reconfigure temporarily. 

Sleeping lower to the ground, or on a cooler level of your home, can reduce the ambient temperature by several degrees.

10. Consider cooling sleep accessories

Beyond mattresses and bedding, there are also accessories that help regulate heat, like bamboo undersheets, cooling mattress protectors, or gel-filled pillows. Just be mindful of synthetic materials that can actually retain heat. 

If you want to keep things as natural as possible, choose breathable layers and open-weave fabrics. These help your body cool down gradually and gently.

A cool bedroom is not a luxury, it’s essential for deep, restorative sleep. By using natural materials, smart ventilation, and season-appropriate routines, you can sleep well even during the height of summer.
