COVID-19 continues to circulate in France, making face masks essential in many situations. They're rarely comfortable, but scorching heat makes them downright challenging. With rising temperatures, learn how to wear your mask without suffocating: 12 proven tips to beat the sauna effect, even in extreme heat.

Black absorbs heat—a fact well-known in fashion. Light clothing is a summer staple for this reason. Dr. Anne Rimoin, professor of infectious diseases, confirms: "Dark colors get warmer faster and draw the sun towards you." The same applies to masks. Opt for light colors like white or blue in the heat; save dark ones for cooler days.
Choosing between synthetic (like polyester) and cotton masks? Go with cotton. It promotes easier breathing and greater comfort, even if it doesn't wick moisture as well. These factors matter during long wear in 35°C heat. As Dr. Rimoin notes, "how you breathe through a material is as important as how it stops" the virus. A hard-to-breathe mask won't stay on—especially in the heat.
Breathing technique matters with a mask. The Robert-Sauvé Research Institute for Occupational Health and Safety (IRSST) recommends nasal breathing with mouth closed. Mouth breathing creates more heat and moisture trapped in the mask. Nasal breathing works for light to moderate effort, per IRSST: "It is only possible to preserve nasal breathing during light to moderate effort." Avoid masks during intense physical activity.
For hot-weather tolerance, proper fit is key. IRSST advises: "choosing a mask that fits the shape and size of the face well can reduce discomfort." A well-fitted mask with adjustable nose bridge and head straps extends wear time comfortably. Note: Mouth-only coverage doesn't protect against coronavirus. CNRS researcher Étienne Decroly warns: "A lot of people stick their noses out of the mask: wearing it that way, it can't be useful."
Wet from sweat or rain? Replace it immediately—a damp mask loses effectiveness. Infectious disease specialist Dr. Benjamin Davido at Robert-Poincaré Hospital states: "A mask, when wet, is no longer effective." Switch to a clean, dry one.
Heat plus masks can cause facial irritation or pimples. Prevent this with thorough moisturizing. Try aloe vera gel for hydration, soothing, and a cooling effect. If needed, layer a handkerchief under fabric masks.
