11 Thyroid Problem Early Warning Signs You Should Not Ignore

4. Temperature sensitivity and changes in sweating

Do you find yourself shivering while others are comfortable, or sweating when everyone else feels fine? Temperature tolerance often shifts with thyroid dysfunction. An underactive thyroid commonly causes cold intolerance. You may reach for an extra sweater or prefer hot beverages like masala chai more than before. On the flip side, an overactive thyroid raises baseline body temperature and can cause excessive sweating, flushing, or heat sensitivity that affects daily chores and sleep. These effects happen because thyroid hormones help regulate how cells produce and use energy, which influences heat production. Note whether these changes are new and whether they come with other symptoms on this list. Small observations—like needing a thicker glass of haldi doodh at night or suddenly sweating while walking to the market—can be useful clues to share with your clinician.
