How to stop night sweats before your period

Hormone changes in the days before bleeding can alter the body's temperature regulation. A warm room, heavy bedding, alcohol, spicy food, stress, fever, or some medicines can add to the problem. A short-lived, repeating pattern is different from sweating that soaks clothing or bedding without a clear cycle pattern.

Use light cotton or moisture-wicking sleepwear and keep a spare top nearby. Ventilate the room, choose lighter bedding, and avoid exercising intensely or taking a hot bath just before bed. Sip water during the day; replace fluids after a very sweaty night. Record the cycle day, severity, temperature, medicines, alcohol, and other symptoms so a clinician can see whether the timing is consistent.

Arrange an appointment if night sweats continue outside the premenstrual days, repeatedly drench bedding, disturb sleep, or come with fever, unexplained weight change, swollen glands, cough, diarrhoea, palpitations, or marked tiredness. Conditions such as hyperthyroidism, menopause, infections, and blood disorders can also present with night sweats, so the symptom's pattern and accompanying signs matter.

Could my medicines, thyroid function, or menstrual hormone changes contribute? What details should I record? Which symptoms would make testing more urgent?
