Across the country, scorching days are coming one after the other. But the nights, which do not bring the expected coolness for rest, are undoubtedly the most difficult to live with. In this stifling context, many city dwellers are seriously considering sleeping on their balconies. But is this really a beneficial option? What are we really risking?
Sleeping outside does not eliminate the risks linked to heat
At first glance, spending the night outside may seem like a good idea, especially when the thermometer struggles to drop below 25°C in your accommodation. However, this solution is not without danger.
“I do not recommend sleeping on a balcony in the event of high heat, unless there is a very punctual emergency and a truly secure balcony”, warns Dr. Gérald Kierzek, emergency physician and medical director of True Medical.
Indeed, even outside, the body remains subject to the effects of heat, particularly during the famous “tropical nights”, when the temperature does not drop below 20°C. The body then still struggles to cool itself properly.
“Heat can cause dehydration, exhaustion, discomfort or heat stroke, and nighttime exposure does not eliminate these risks if the air remains hot,” recalls the specialist.
Mosquitoes, noise, pollution… the other disadvantages
Beyond the heat itself, sleeping on a balcony exposes you to other inconveniences that can seriously degrade the quality of sleep.
“A balcony exposes you more to mosquitoes, noise, urban pollution and poorer quality sleep”,
emphasizes Dr. Kierzek.
Nocturnal noise pollution, common in the city, can increase the number of awakenings and prevent restful sleep. As for mosquitoes, they can turn the night into a real ordeal, particularly in regions where the tiger mosquito is well established.
The risk of accident should not be neglected either. Falling asleep deeply, waking up disoriented during the night or an unsafe arrangement can increase the risk of falling, particularly among children, the elderly or when the balcony is not perfectly secure.
In what cases can this help?
Sleeping on your balcony can exceptionally constitute an emergency solution, but only under certain very strict conditions.
“This can possibly help if the balcony is well protected, without the risk of falling, not very noisy and less hot than the bedroom. But this is not a general public health recommendation to sleep better during the heatwave”insists the doctor.
Before moving outside, it is therefore advisable to check that the balcony is completely secure, that the temperatures there are actually lower than inside and that the environment allows a minimum of rest.
Also from a legal point of view, no law strictly prohibits sleeping on your balcony. On the other hand, in co-ownership, the internal regulations can govern certain uses of this outdoor space. Occupants must also take care not to create nuisances for the neighborhood.
Good reflexes to sleep better despite the heatwave
To get through episodes of extreme heat, Dr. Gérald Kierzek recommends above all doing everything possible to keep your home cool.
Among the most effective actions:
- Close shutters, blinds and windows during the day;
-
Ventilate early in the morning and late in the evening, when temperatures drop;
- Drink water regularly, even without feeling thirsty;
- Choose light clothing and sheets made from natural fibers;
- Use a fan or damp cloths to promote cooling.
“If the heat becomes painful at night, it is better to try to cool the room or spend a few hours in a cool place rather than sleeping outside.”concludes Dr Gérald Kierzek.
In the event of symptoms such as dizziness, nausea, severe headache or feeling unwell, it is recommended to cool down quickly and seek medical advice.
