Frequent hot flashes and sweating may be signs of various diseases or physiological conditions, including but not limited to: 1. Menopausal symptoms: As women experience declining ovarian function and reduced estrogen levels, the sensitivity of the body's temperature regulation center increases. Common symptoms include hot flashes and night sweats, particularly prevalent in women over 45 years of age. 2. Endocrine disorders: For example, hyperthyroidism, in which excessive secretion of thyroid hormones accelerates metabolism, leading to hot flashes and excessive sweating. 3. Traditional Chinese medicine (TCM) body constitution factors: Such as yin deficiency with internal heat, where insufficient body fluids result in spontaneous internal heat that forces fluids outward, causing sweating—especially prominent at night. 4. Environmental factors: Prolonged exposure to high temperatures or wearing excessive clothing can impair the body’s ability to dissipate heat, resulting in hot flashes and sweating. If frequent hot flashes and sweating occur, it is recommended to consult a healthcare professional for proper evaluation and treatment based on individual circumstances.
