Which symptom is more characteristic of hyperthyroidism than hypothyroidism?

Explanation:
Hyperthyroidism speeds up metabolism and increases sympathetic nervous system activity. This leads to a restless, overactive state that often makes it hard to fall asleep or stay asleep, so insomnia is a common symptom. The excess thyroid hormone drives heightened CNS arousal and greater energy use, which disrupts normal sleep patterns. Bradycardia, dry skin, and cold intolerance are more typical of hypothyroidism, where low thyroid hormone slows the heart, reduces skin moisture, and lowers body heat production. So, insomnia is the symptom that aligns more with hyperthyroidism than hypothyroidism.
