Considerations:

Heat intolerance often produces a feeling of being overheated and can produce heavy sweating. Heat intolerance usually comes on slowly and persists long-term.

Common Causes:

• Thyrotoxicosis (excess thyroid hormone, which increases the basal metabolic rate, causing body temperature to rise)
• Amphetamines such as appetite suppressants
• Caffeine
• Menopause
