What causes it

Night sweats are the nocturnal equivalent of hot flashes. Declining oestrogen disrupts the hypothalamus's thermoregulatory set point, causing it to misread normal body temperature as too hot and triggering sweating to cool down. The threshold at which this misfire occurs narrows as oestrogen falls — meaning smaller temperature fluctuations (a warm room, stress, alcohol) can trigger episodes that wouldn't have affected you previously.

How to track it

Log night sweats by frequency (number of episodes), severity (mild dampness vs drenching), and which part of the night they occur. Track alongside alcohol intake, room temperature, and stress level — all three are common triggers that are within your control. Showing a doctor a 2-month log of night sweat frequency and severity is far more useful than estimating from memory.

When to see a doctor

Night sweats that are severe, occur throughout the night, or are associated with fever, unexplained weight loss, or drenching sweats unrelated to menopause timing should be evaluated. Night sweats can occasionally signal infection, lymphoma, or other conditions that require investigation.
