What to know
Plan the day around heat exposure
Move long walks and outdoor attractions away from the hottest period, shorten routes and place air-conditioned stops before you feel unwell. Older adults, young children and people with medical conditions may need a more conservative plan.
A portable fan can improve comfort, but hot dry airflow and dehydration still require water, shade and rest. Do not let a gadget justify staying outside when symptoms begin.
What to know
Treat symptoms as a decision point
Headache, dizziness, nausea, unusual fatigue, confusion or inability to drink are not normal sightseeing discomfort. Move to a cool place, loosen clothing, cool the body and use the official first-aid guidance. Call 119 for an emergency.
