Understanding the impact of heat on the body

When temperatures climb, our body enters a silent struggle. It attempts to maintain its thermal balance through perspiration or vasodilation. But during heatwaves or prolonged periods of heat, these mechanisms wear out. The result is well known: insomnia, intense fatigue, headaches, nervousness. This thermal stress spares no one.

The hypothalamus, that small region of the brain responsible for regulating body temperature, plays a central role. It acts like an internal thermostat, detecting any thermal variation. But when heat is excessive or prolonged, this thermoregulatory center can become saturated, triggering internal overheating and an accumulation of uncomfortable sensations.

In these moments, the need for a rapid, natural, and effective response becomes essential.

Héra: a portable, intelligent, and natural solution

Faced with this universal need for coolness, the Héra device stands out for its simplicity and performance. This portable cryotherapy device delivers intense cold, between 5 and 10°C, to strategic areas of the body such as the neck, wrists, or chest. In less than ten seconds, a feeling of relief takes hold.

Héra is lightweight, silent, autonomous, and integrates discreetly into daily life—whether at home, in the office, or on the go. It requires no freezer, no water refills, and no chemicals. It is a clean, dry, and fast solution: a true anti-heat reflex.

How cold acts on the body: the three key effects

Why does cold act so effectively?

When applied to thermosensitive areas like the neck or chest, the intense cold activates three natural mechanisms:

• It sends a soothing signal to the brain, via the hypothalamus, to interrupt the sensation of overheating.
• It triggers local vasoconstriction, reducing blood flow to the surface of the skin, and therefore the perceived heat.
• It stimulates the parasympathetic system, which promotes relaxation, reduces stress, and improves mood.

A discreet response to discomfort in public spaces

In crowded transport, poorly ventilated open-plan offices, or during outdoor events, fanning oneself with a hand fan or a pocket fan can be awkward, impractical, or frowned upon in certain professional or social contexts. Héra establishes itself as a discreet and elegant solution. By simply applying cold to a strategic area, you reduce the sensation of heat without attracting attention or disturbing your environment. Ideal for meetings, waiting rooms, or on public transport, it allows you to quickly regain comfort with complete ease.

FAQ – Everything you need to know about Héra

1. Is it safe? Yes. The cold remains between 5 and 10°C, with no risk to the skin if used reasonably.
2. How long does a session last? A few seconds are enough to feel the effect. You can repeat the application as often as necessary. Sessions last 1 minute 30 seconds.
3. How often should it be used? No limit: as soon as you feel overheated, fatigued, or experience heat-related symptoms.
4. Can it relieve a headache caused by heat? Yes. It combines a local vasoconstrictor effect with a relaxing effect, helping to alleviate mild headaches.
5. Is it better than a fan or a misting spray? Yes. These methods are passive and imprecise. Héra intervenes directly on the area to be cooled, without moisture.
6. Does it work outside the summer season? Absolutely. It can also be used in cases of stress or fatigue!
