PSA from a doctor: heat exhaustion signs people ignore
Seeing a lot of this lately, so a quick list. Heavy sweating, cold clammy skin, headache, nausea, dizziness, muscle cramps, feeling weirdly tired. If that's you: get somewhere cool, loosen clothes, sip water, cool cloths on the neck and armpits.
If someone stops sweating, gets confused or faints, that's past exhaustion, call for help. And check on older neighbours, they often won't complain until it's bad.
