Perimenopause hot and cold sensations

Hormone fluctuations can affect the brain's temperature-control centre. A hot flush may bring sudden warmth, sweating, and a later feeling of chill as the body cools. Night sweats can interrupt sleep. Fever, infection, thyroid problems, low blood sugar, medication effects, anxiety, and an overheated room can feel similar, so the surrounding symptoms and your temperature reading provide useful clues.

Note when episodes occur, how long they last, what you were doing, and whether you had sweating, palpitations, or a measured fever. Wear removable layers, keep the bedroom cool, use a fan, and sip fluids. Regular movement and a consistent sleep routine may support overall wellbeing. A clinician can discuss hormonal or non-hormonal treatment when flushes disrupt sleep or everyday activities.

Seek urgent help for confusion, severe weakness, chest pain, breathing difficulty, fainting, or a very high temperature. Arrange prompt review for repeated chills with fever, unexplained weight change, painful urination, persistent cough, or a new severe headache. Book routine care if episodes are frequent, worsening, or affecting sleep and work.

Ask whether the pattern fits hot flushes, whether another cause should be checked, and which treatment options fit your medicines and health history.
