Meta- was first used in that way in metaphysics and has been extended to a number of other disciplines, giving us such words as metapsychology and metamathematics.. Metadata takes the transcending aspect a step further, applying it to the concept of pure information instead of a discipline. Metadata is a fairly new word (it appeared in the latter half of the 20th century), whereas data can be traced back to the middle of the 17th century. First Known Use of metadata 1983
A hot flash is a brief feeling of intense warmth and sweating. Hot flashes commonly occur in women around the time of menopause. Researchers do not know exactly what causes hot flashes. Current theories suggest hot flashes are due to a menopause-related drop in the body's level of female hormones called estrogens. This drop affects the hypothalamus, an area of the brain that regulates body temperature.
Hormone therapy (HRT-estrogen plus progesterone or estrogen alone for women without a uterus) can help alleviate hot flashes, night sweats and other symptoms, but it may not be recommended for women with a history of breast cancer or for those with heart disease.
