Keep your house cool. Turn on your air conditioning (if possible), block the sun by closing curtains or blinds, or relocate to a cooler location such as a basement or public cooling centre. Fans alone cannot effectively lower core body temperature, especially for older adults. Use fans to pull in cooler air from outdoors, but if you or someone you care for is experiencing symptoms of heat illness, find a cooler space.
