Fig. 3From: Hypothyroidism in hibernating brown bearsShared physiology between hypothyroid humans and hibernating bears. Bears are hypothyroid during hibernation. Hibernating bears share physiology with hypothyroid humans, including decreased basal metabolic rate, bradycardia, hypothermia, fatigue, and constipation, and we therefore speculate that hypothyroidism is a key regulator of hibernation in bears.
