Heat tips

Choose light, loose cotton or linen when it is hot. It feels airier and helps your body cool itself more comfortably.

When you feel overheated, cool your forearms, neck, or feet first. It can give quick relief without jumping straight into a cold shower or cooling the whole room.

Track temperature and humidity, but decide when to ventilate using occupancy, CO₂, and moisture sources too. Keep the room cooler without sacrificing fresh air.

Even on warm days, people add CO2 and moisture indoors. Use short, targeted ventilation when the room starts to feel stale.

A parked car can turn dangerously hot fast. Take pressure containers, batteries, glass, medicine, food, people, and pets with you.

Keep your home cool without letting it turn stuffy: during heat, ventilate briefly when humidity or CO2 starts to build up.

Shade sunny windows, but do not leave occupied rooms without air exchange all day. Ventilate according to air quality, occupancy and temperature, not a rigid windows-closed rule.

Damp towels can help on hot days, but only with airflow and humidity control. If the room feels humid, ventilate briefly even during the day.
