What does heat intolerance feel like with obesity?

You might feel hot during gentle movement, in humid weather, or after sitting in a warm place. Sweat may collect around skin folds or soak clothing, and cooling may take longer after you stop moving. Chafing, prickly heat, thirst, fatigue, and breathlessness with exertion can add to the discomfort.

Body size, insulation from fatty tissue, reduced surface area for releasing heat, and difficulty moving air across the skin can all affect cooling. Heat intolerance is not specific to obesity; thyroid problems, medicines, infection, menopause, and dehydration can produce similar symptoms.

Use air conditioning or a fan, drink water before and during activity, and choose loose, breathable clothing. Take breaks in shade or a cool room and dry skin folds gently to reduce irritation. Build activity gradually and stop if you become dizzy, weak, nauseated, or unusually short of breath. A clinician can review the symptom, medicines, sleep, mobility, and other health conditions rather than assuming one cause.

Get urgent help for confusion, fainting, hot dry skin, severe weakness, chest pain, severe breathlessness, or inability to drink. Seek medical advice for repeated episodes, symptoms that occur in cool settings, or sweating with palpitations, fever, unexplained weight change, or worsening exercise tolerance.

Ask what may be affecting your temperature control, whether medicines or thyroid testing should be reviewed, and how to exercise safely in warm weather. Mention skin irritation, snoring, daytime sleepiness, or breathlessness if these occur with overheating.
