Is it normal to still have night sweats 20 days after giving birth?
Under normal circumstances, mild night sweats 20 days after childbirth are considered a normal phenomenon. However, excessive sweating accompanied by fatigue and dizziness should be taken seriously. Hormonal changes and metabolic adjustments during postpartum recovery can lead to abnormal sweat secretion. The detailed analysis is as follows:

After delivery, the sharp drop in estrogen levels prompts the body to expel excess fluid through sweat. Sweating is particularly noticeable after physical activity, eating, or during nighttime sleep. This is part of the body's self-regulating process. Such perspiration is usually mild, short-lived, and causes no significant discomfort once wiped away. It gradually decreases as the body recovers.
If night sweats are accompanied by symptoms such as pale complexion, palpitations, shortness of breath, or cold hands and feet, or if sweating soaks clothing and occurs frequently at night, it may indicate severe deficiency of qi and blood following childbirth. Prolonged symptoms like these can impair recovery, reduce immunity, and increase the risk of colds or infections. Timely improvements through dietary and lifestyle adjustments are necessary.
In daily life, wear breathable, sweat-absorbing cotton clothing and change clothes promptly after sweating to prevent chills. Diet-wise, consume more qi- and blood-nourishing foods such as lean meat, eggs, and red dates. Ensure adequate rest and avoid overexertion.
