Light sleep and frequent awakenings? Here’s how to sleep better in summer

Cover insonnia estate

Summer brings longer days, late nights and a desire for relaxation, but this often doesn’t translate into a good night’s sleep. When temperatures rise, it becomes more difficult to sleep well: the body struggles to relax, sleep becomes lighter and night-time awakenings increase.

Fortunately, there are effective strategies for improving comfort and sleep quality even in the hottest months. Let’s take a look at the topic in this article.

Why do we sleep badly when it’s hot?

The summer heat negatively affects the body’s thermoregulation, a fundamental process for falling asleep. If the ambient temperature remains high, the body struggles to lower its internal temperature, making it more difficult to fall asleep and maintain deep sleep. The result? Interrupted, light and unrefreshing sleep.

High humidity, poor ventilation or non-breathable bed linen can also worsen the situation, leading to sweating and discomfort.

Practical remedies to improve sleep in summer

While we can’t change the summer climate, we can influence many factors that affect sleep quality. From our evening habits to the environment in which we sleep, and the choices we make regarding mattresses and bed linen, there are simple and effective strategies to make the nights cooler and more restful.

Here are some tips to help you combat the heat and enjoy a deeper and more continuous sleep.

  • Keep your bedroom cool and well ventilated
    Open the windows early in the morning and in the evening, use fans or air conditioners with a “sleep” function, and block out direct light during the hottest hours: all small gestures that contribute to creating an environment conducive to rest.
  • Choose lightweight, breathable fabrics
    Opt for cotton, linen or bamboo sheets, natural materials that promote breathability and reduce heat retention. Avoid synthetic fibres or heavy padding.
  • Follow the rules of sleep hygiene
    Even in summer, sleep hygiene is important: avoid using electronic devices before going to bed, try to eat lightly and not too late, and maintain a regular routine for going to bed. Taking a warm bath or shower can help your body relax before going to bed.

Beat the summer heat with the right mattress

Nights can be hot, and the support you sleep on can also affect how well you sleep: an inadequate mattress can trap heat and worsen sleep quality. This is why it is important to choose breathable materials that are suitable for the season.

  • Breathable mattresses for an ideal microclimate
    Breathable mattresses, made with open-cell foams or channeled ventilation structures, promote heat dispersion and keep the body cool. Humidity is reduced, comfort improves, and sleep becomes more continuous.
  • Memory foam: relaxing comfort without overheating
    The new generation of memory foam, which is breathable and thermosensitive, adapts to the body’s shape, offering uniform and relaxing support. The most advanced versions are designed to dissipate excess heat and provide a welcoming sensation without that annoying “hot feeling”.

Choose the best for your rest… All year round!

Light sleep and frequent awakenings do not have to be inevitable in summer: by adopting simple daily habits and choosing a breathable and comfortable mattress, such as the Sanremo Classic, it is possible to significantly improve the quality of sleep.

Combining good habits with an appropriate bed system for the season is the key to sleeping well, even when it’s hot… or very hot.
