Overview

• A recent survey of 2,000 adults found nearly a third wake up in the middle of the night regularly, with women disproportionately affected.
• Medical experts emphasize that frequent nighttime awakenings may signal thyroid dysfunction, either underactive (hypothyroidism) or overactive (hyperthyroidism).
• Thyroid hormones T4 and T3 regulate metabolism, energy levels, and the sleep–wake cycle; imbalances can disrupt sleep patterns and overall health.
• Hyperthyroidism can cause symptoms like anxiety, elevated cortisol, and restlessness, leading to early-morning awakenings, while hypothyroidism often results in persistent fatigue.
• Doctors recommend a simple blood test for individuals experiencing sleep disturbances alongside symptoms such as fatigue, weight changes, or mood swings to detect thyroid issues early.
