Shows and lukewarm water consumption, wet bath towel, ice cubes or pillowcase in the fridge: all tips and means are good to avoid suffering from heat. The fan is thus often the best ally of scorching summer.
A hot air brewing that can be more dangerous than beneficial
The fan, a contrario of the air conditioning system which creates fresh air, will brew the surrounding air to emit an artificial air current thanks to its blades. The power of the object varies according to the fan. In addition, some ingenuities are to be known to make optimal use of your fan, regardless of its purchase price and its model.
First, you should know that from 36 ° C, a fan is useless. As Glen Kenny, a physiologist from the University of Ottawa, said, published a study on this question in May in the journal Lancet Planetary Health, relayed by Le Point, the individual’s body temperature can no longer be refreshed since there are no differences with the temperature of the ambient air.
According to the expert, it can even be dangerous: “There can be a false impression of freshness that leads to too much physical activity. This is particularly problematic for the elderly”. The individual is not refreshed, however the wind can increase perspiration which helps to cool the body. However, the elderly sweat less and can dry up and therefore dehydrate faster.

If the temperatures in your accommodation exceed 36 ° C, it is therefore recommended to cover your fan with a laundry or a damp towel, since the water will allow the diffusion of a fresher air.
Another known technique is to fill a bottle of water, then put it in the freezer. Once the container of the frozen bottle, it is a question of placing the bottle in a bowl at the front of the fan of the fan. The air expelled from the fan will capture the ambient freshness released by the plastic bottle and help to cool your living space.
