33, 34, 35 ° C … The temperatures continue to climb, and it becomes difficult to cool off at the office or at home during the heat wave. The simplest solution to better withstand the heat (when you do not have the chance to have the air conditioning of course): the good old fan. But beware, letting it light up all night long to sleep "fresh" would not be safe for our health.
Drying, sinusitis and cramps
Thus, in an article of "Sleep Advisor Magazine" 1 Spotted by the site "Pourquoidocteur.fr" 2 Dr. Mark Reddick indicates that when a fan circulates the air in the room, dust and pollen enter our sinuses. "If you are prone to allergies, asthma and hay fever, it could cause a lot of problems," he says.
The fan also has the disadvantage of drying out both the skin, nasal pbadages, throat and eyes, especially in people who sleep in the mouth and / or slightly open eyes. It can then cause redness, irritation or sinusitis. "The constant diffusion of dry air could affect your sinuses, and if the dryness is really extreme, your body could then produce more mucus to try to relieve them, so you'll end up with a stuffy nose and headaches." warns the doctor. Finally, the muscles can also suffer from the air brewed: they contract and then cause cramps, or torticollis.
If, despite all these warnings, you still want to use a fan, you should avoid directing the device directly to the bed, and prefer the "oscillation" option so as not to diffuse the air continuously. in one direction. If your device allows it, set a schedule so that it turns off automatically after a few hours and you do not spend the night in the air.
