The hot flush, or flash, is well known as the classic menopausal symptom and affects 60–85% of menopausal women. Hot flushes and sweats are called vasomotor symptoms and vary immensely in both their severity and duration; for many women, they occur occasionally and do not cause much distress, but for about 20% they can be severe and can cause significant interference with work, sleep and quality of life.
Women are affected by vasomotor symptoms on average for about 2 years but, for about 10%, symptoms can continue for more than 15 years. Hot flushes usually last 3–5 minutes and are thought to be caused by a change in the temperature-controlling part of the brain.Normally, there is a daily pattern of rises and falls in your body temperature, being lowest at about 3am and highest in the early evening.
These small changes are not normally noticed, but a menopausal woman may flush with every temperature rise, whether these are normal changes or not – for example, moving between areas of different temperature or having a hot drink
– because of a change in the setting of the temperature control centre in your brain; your body thinks that it is overheating even when it isn’t. To try to cool your body down, a variety of chemical reactions cause the blood vessels in the skin to open up, giving the sensation of a rush of heat, and sweat glands release sweat to dissipate heat. It is believed that the changes in various hormone levels that occur around the time of the menopause, lead to the change in the setting of the temperature control centre, but the exact underlying mechanism is still unclear.
Other factors that can also cause flushes include being overweight, alcohol, excess caffeine, spicy foods, monosodium glutamate and some medications. Eating a healthy diet can be helpful.
