10 Tips for Sleeping in the Heat

During the summer, sleeping in the heat can be uncomfortable and even frustrating. The ideal temperature for restful sleep is between 18 °C and 22 °C. When the thermometers rise, it is essential to adopt strategies that keep the bedroom cool and pleasant.In this article we share 10 effective tips for sleeping better during the heat, including how to choose the best memory foam mattress for the summer.

1. keeping the bedroom cool during the day

Lower the blinds or close the curtains during the hottest hours to prevent the sun from entering. At night, open the windows to encourage air circulation. A fan can create a pleasant current and improve the thermal sensation.

2. Elegant bed linen and suitable 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 remove heat and moisture.

3. Take a warm shower before going to bed

A shower with tempered water helps to gradually reduce body temperature, providing a feeling of coolness and making it easier to fall asleep.

4. Hydration during the day

Maintaining good hydration is essential, especially on the hottest days. However, avoid drinking large quantities of water just before going to bed so as not to interrupt your rest with frequent visits to the bathroom.

5. Avoid heavy food at night

Opt for light meals and avoid spicy or fatty foods. Heavy digestion can increase body temperature and make sleep difficult.

6. Apply simple cooling techniques

Place a damp towel or cold water bottle in front of the fan to cool the air. Another effective option is to lightly moisten the fan with cold water before starting.

7. Adopt sleeping positions that favor ventilation

Sleeping on your side or with your mouth down facilitates air circulation around your body. Avoid recumbent positions, which can increase the sensation of heat.

8. An ideal mattress for sleeping in the heat

The choice of mattress is crucial for a good rest in summer. Mattresses with memory foam offer comfort and adaptability, but the ideal is to opt for models that favor air circulation and heat dissipation.

We highlight the Luxury Gel Mattress - Bagged Mules, which combines viscoelastic Gel Fresh with a bagged mules system.
This mattress stands out for being:

  • Fresh and breathable.

  • High firmness and excellent adaptability.

  • With 3D fabric sides that favor ventilation.

  • Ideal for those looking for a memory foam mattress for the summer.

  • Recommended for those suffering from intense night-time heat.

9. Viscoelastic topper: a cooling solution

If your current mattress doesn't offer the desired freshness or comfort, a mattress topper can be an excellent alternative. Some models include breathable fabrics and viscoelastic with a cooling effect.

We recommend the Viscoelastic Topper, with:

  • 2 cm viscoelastic cover for greater comfort.

  • Elastic straps for extra stability.

  • HD foam padding that provides firmness and density.

  • Side band in breathable 3D fabric for better ventilation.

  • Stretch fabric with Aloe Vera that improves freshness.

A memory foam topper can be a practical way of improving the thermal comfort of your current mattress.

10. Maintain a constant dream routine

Establish regular sleeping and waking times. Avoid turning on the lights before bedtime, as blue light interferes with the production of melatonin, the sleep hormone. A stable routine helps the body to prepare better for rest, even on dark nights.

Sleeping well in summer is possible with a few adjustments to the environment, the routine and the choice of mattress. Choosing a memory foam mattress with good thermal regulation makes the difference on the warmest nights.

If high temperatures interrupt your rest, it may be time to overhaul your mattress. Simple solutions, such as a memory foam topper, can completely transform the quality of your sleep.
