Thyroid Conditions and their Impact on Sleep

Improving your Sleep Quality

GImproving sleep quality is an important part of managing a thyroid condition. Thyroid hormone imbalances can affect energy levels, body temperature, heart rate, and stress response, all of which influence how well you sleep.

A consistent routine and appropriate treatment can help reduce sleep disruption over time.

Tips for hyperthyroidism and sleep

If you have an overactive thyroid (hyperthyroidism), your metabolism is faster than normal. This can lead to restlessness, anxiety, and difficulty winding down at night.

Helpful sleep strategies include:

• Take thyroid medication exactly as prescribed to help stabilise hormone levels
• Maintain a consistent sleep and wake routine, even at weekends
• Avoid caffeine in the afternoon and evening, as it can worsen restlessness
• Limit alcohol, which can disrupt deep sleep cycles
• Create a calm sleep environment (dark, cool, and quiet)
• Reduce screen time before bed to support natural melatonin production

Tips for hypothyroidism and sleep

If you have an underactive thyroid (hypothyroidism), you may experience fatigue, low energy, and prolonged sleep, but still feel tired during the day.

Helpful sleep strategies include:

• Take thyroid hormone replacement therapy as prescribed
• Keep a regular sleep schedule to support your body clock
• Prioritise stress management techniques such as relaxation or breathing exercises
• Avoid large or heavy meals close to bedtime
• Engage in light daily activity or exercise to improve energy balance
• Consider cognitive behavioural therapy (CBT) if sleep problems persist
