chaleur et insomnie

Heat and insomnia: why does your body have trouble sleeping when it's hot?

When temperatures rise, our nights sometimes become a real battle against the heat . You toss and turn, you sweat, you can't find the ideal position... What if the problem wasn't just your mattress or your duvet? Understanding why we sleep badly when it's hot also means learning how to get a good night's sleep despite the heatwave. We'll explain everything to you, and above all, we'll give you natural solutions to remedy it. 🧊


🌡️ Body temperature: conductor of sleep

Your body is a true internal clock . Every night, it naturally lowers its temperature by about 1°C to help you fall asleep. This is called thermoregulation .

Problem? When it's hot , this drop becomes difficult , even impossible . As a result, your brain receives a confusing signal and blocks the secretion of melatonin , the sleep hormone. 😩

A room above 22°C is sometimes enough to disrupt this mechanism. The ideal temperature for sleeping? A room between 16°C and 18°C, no more, no less.


🧠 A brain on permanent alert

In extreme heat, your autonomic nervous system remains on alert. Your body tries to cool you down: sweating, dilating blood vessels, accelerating heart rate... All of this creates internal overstimulation that prevents your brain from resting. And guess what? The more you focus on not sleeping, the less you sleep.


🛌 Sweat: an unexpected sleep disruptor

Heat means sweating... and often discomfort. When you sweat at night:

  • You move more
  • You wake up more frequently
  • You may experience discomfort or itching

Sweat therefore acts as a micro-thermal alarm clock . And the more frequent these alarm clocks are, the less deep and restorative your sleep will be.

➡️ Maholi Tip: Sleep with natural, breathable materials, such as organic cotton. And choose lightweight, light-colored sheets to reflect heat rather than absorb it.


A natural solution to help you sleep better despite the heat🧊

At Maholi, we offer you a simple, natural solution with no side effects: apply a cold pack to your perineum before going to bed. This gentle little gesture helps your body find its ideal temperature to fall asleep more easily. The cold soothes your nervous system, reduces the production of cortisol (the stress hormone) and stimulates the secretion of melatonin , the sleep hormone.

Result: your body relaxes, your mind slows down, and you slip more serenely into the arms of Morpheus. 😉

  • Helps lower your core temperature
  • Stimulates melatonin production
  • Soothes tension and stress
  • Promotes falling asleep and deeper sleep

💡 Our cryo kits are designed to last up to 2.5 hours of gentle cold, without thermal shock, for a guaranteed cocoon effect.

Why the perineum?

The perineum is an intimate and central area of the body, extremely vascularized and connected to numerous nerve plexuses , which makes it a strategic point to act on your entire body. By applying cold to this precise area, we create a targeted but deep cooling , capable of lowering the internal temperature of the body while triggering a state of general relaxation . It is a practice derived from ancestral hydrology, brought up to date with modern, soft and cocooning pockets. And at Maholi, we offer you maximum comfort so that your freshness routine becomes a real well-being ritual, summer and winter!


🌿 Conclusion: heat ≠ insomnia, if you adopt the right actions

Sleeping in hot weather isn't an impossible task. By understanding the link between temperature and sleep , you can implement simple and natural solutions: adapt your bedding, ventilate your room, or incorporate perineal cryotherapy into your evening routine.

👉 At Maholi, we offer you a fresh, caring and taboo-free alternative to help you sleep better, even in the middle of a heatwave.
