3 Heat-Safety Checks When You Sweat Less Than Usual

A dry shirt after a hot walk can seem like one less thing to deal with. If you are sweating much less than usual, bring that change to a clinician. It deserves attention even if fewer shirt changes sound appealing.

Three heat-safety checks

1. Where has sweating changed? Note whether it affects one area or several, when you first noticed it and whether you also feel hot, dizzy or weak. Anhidrosis can affect specific areas or the whole body.¹

2. What medicines need review? Some medicines interfere with sweat-gland function. Bring prescription and nonprescription product names to the appointment. Do not discontinue a medicine without speaking to the prescriber.¹

3. How will you get cool? Favor a cool environment, loose clothing and less exertion. If symptoms develop in heat, move indoors or into shade and use cool damp cloths. Seek medical attention if cooling does not improve symptoms.¹

Know the emergency signs

Confusion, slurred speech, seizures or collapse in the heat can signal heatstroke. Call 911 or your local emergency number immediately for suspected heatstroke, move the person out of heat and start cooling with cool water or wet towels while help is coming.²

Heatstroke can involve dry skin or heavy sweating. Sweating does not rule it out.²

For the routine appointment, describe the outing you want to manage: the walk from the parking lot, an outdoor shift or a trip planned for warm weather. Ask what activity advice applies while the cause is assessed.

Arms Up includes a Fresh Log and a visit script. Use them to organize your observations and questions alongside the clinician’s heat-safety advice. See the book.
