Heat intolerance treatment

Heat intolerance is a symptom rather than one disease, so a useful plan depends on the pattern. A clinician may review medicines, examine your heart rate and hydration, and consider thyroid or other tests. If hyperthyroidism is involved, treating thyroid overactivity may reduce heat sensitivity. If body size, reduced fitness, infection, or another illness contributes, management focuses on that factor. Heat exhaustion needs prompt cooling, rest, and fluids, with escalation if recovery is not clear.

Stay in air conditioning or shade, wear light breathable layers, use cool cloths, and avoid strenuous activity during the hottest period. Sip fluids regularly unless a clinician has restricted them. Keep a record of triggers and any medicines taken around an episode. Do not start supplements, change thyroid treatment, or stop prescribed medicines without professional advice. A personalised plan may include pacing, work adjustments, or a review of conditions that affect temperature control.

Seek urgent medical help for confusion, fainting, seizure, chest pain, severe breathing difficulty, persistent vomiting, or worsening weakness after heat exposure. A prompt appointment is sensible for repeated episodes, new palpitations, unexplained weight change, or reduced sweating. These features can point to a problem needing assessment rather than home cooling alone.

Ask what may be triggering the symptom, which treatment is intended for the cause, how much fluid is appropriate, and what signs mean you should seek urgent help.
