10 Tips for Sleeping in the Heat
During the summer, sleeping in hot weather can be uncomfortable and even frustrating. The ideal temperature for restful sleep is between 18 °C and 22 °C. When thermometers rise, it's essential to adopt strategies that create a cooler, more comfortable environment. In this article, we share 10 effective tips to help you sleep better in hot weather - including how to choose the best memory foam mattress for summer.
1. keep the room cool during the day
Close the blinds or curtains at the hottest times to prevent sunlight from entering. At night, open the windows to encourage air circulation. A fan can create a pleasant draft and improve the thermal sensation.
2. Choose suitable bedding and pyjamas
Opt for natural, lightweight fabrics such as cotton or linen. These materials allow the skin to breathe and help absorb perspiration. Avoid synthetic fabrics, which retain heat and moisture.
3. Take a warm shower before going to bed
A warm bath helps to gradually lower body temperature, promoting a feeling of coolness and making it easier to fall asleep.
4. Hydrate throughout the day
Staying hydrated is essential, especially on hot days. However, avoid drinking large quantities of water just before bedtime so as not to interrupt your rest with frequent trips to the bathroom.
5. Avoid heavy meals in the evening
Prefer light meals and avoid spicy or fatty foods. Heavy digestion can raise your body temperature and make it harder to fall asleep.
6. Use simple cooling techniques
Place a damp towel or a bottle of cold water in front of the fan to freshen the air. Another effective option is to lightly dampen the sheet with cold water before going to sleep.
7. Adopt sleeping positions that favor ventilation
Sleeping on your side or back makes it easier for air to circulate around your body. Avoid curled up positions, which can increase the sensation of heat.
8. Choose an ideal mattress for sleeping hot
The choice of mattress is crucial to sleeping well in summer. Viscoelastic mattresses offer comfort and adaptability, but the ideal is to opt for models with materials that promote greater air circulation and heat dissipation.
We highlight the Luxury Gel Mattress - Bagged Spring, which combines Gel Fresh viscoelastic with a bagged spring system. This mattress stands out for being:
- Cool and breathable;
- High firmness, with excellent adaptability;
- With 3D fabric on the side for ventilation;
- Ideal for those looking for a memory foam mattress for the summer;
- Recommended for people who suffer from high nocturnal heat.
9. Viscoelastic topper: a cooling solution
If your current mattress doesn't offer the comfort or freshness you want, a mattress topper can be an excellent solution. Some models include breathable fabrics and memory foam with a cooling effect.
We suggest the Topper Viscoelastic Overmattress, with:
- 2 cm viscoelastic layer for greater comfort;
- Elastic fasteners for greater stability;
- HD Foam Block for greater firmness and density;
- Breathable 3D fabric strip for temperature regulation and air circulation;
- Stretch knit fabric with breathable Aloe Vera.
A memory foam topper can be a practical way to improve the thermal comfort of your current mattress.
10. Maintain a consistent sleep routine
Establish regular bedtimes and wake-up times. Avoid screens before bedtime, as blue light interferes with the production of melatonin - the sleep hormone. A stable routine helps the body better prepare for rest, even on hot nights.
Sleeping well in summer is possible with a few simple adjustments to your environment, routine and choice of bed. Selecting a suitable mattress, such as one with memory foam and excellent thermal regulation, makes all the difference on hot nights.
If you suffer from sleepless nights due to the heat, it's time to re-evaluate your mattress. Simple solutions like a memory foam topper can transform your rest.
