Flushes and sweats, also known as vasomotor symptoms, occur in 3 out of 4 women during the menopausal years.  They usually start as a feeling of pressure in the head followed by a wave of heat passing over the body. A typical hot flush lasts for a few minutes and causes flushing of your face, neck and chest. They can occur at any time but may be triggered by hot drinks, alcohol, warm room temperatures or stressful situations. You may also get headaches, palpitations or dizziness together with flushes. Hot flushes occurring at night are known as night sweats and can leave you and your bed clothes drenched. Inevitably, your sleep is disturbed adding tiredness to the list of troublesome menopausal symptoms.
