Introduction
In general, hypothyroidism is somewhat associated with post-exercise fatigue. Patients with hypothyroidism experience reduced synthesis and secretion of thyroid hormones, leading to a slower metabolic rate. Additionally, when thyroid hormone levels are low, the excitability of the sympathetic nervous system decreases, which may make patients more prone to fatigue and drowsiness after exercise.
Generally, hypothyroidism is associated with increased fatigue after exercise. The specific analysis is as follows:
Hypothyroid patients experience a decrease in the synthesis and secretion of thyroid hormones, which leads to a slower metabolic rate. This reduced metabolism results in decreased energy consumption during physical activity, potentially causing increased fatigue and sleepiness after exercise. Additionally, thyroid hormones have an excitatory effect on the sympathetic nervous system. When thyroid hormone levels are low, the activity of the sympathetic nervous system decreases. Reduced sympathetic nervous system activity may contribute to increased fatigue and tiredness after exercise. Therefore, hypothyroidism is related to post-exercise fatigue and sleepiness.
It is recommended that patients with hypothyroidism engage in appropriate physical activities under a doctor's guidance and regularly monitor their thyroid function to ensure thyroid hormone levels remain within the normal range. This can help prevent hypothyroidism from affecting quality of life. At the same time, maintaining a healthy lifestyle, such as regular sleep patterns and a balanced diet, can help alleviate symptoms.
