Although it is rare for a woman to have menopause before age 40, it can happen anytime between the ages of 30 and the mid-50s, and even later. Often, the onset of menopause is earlier for smokers than for nonsmokers. Only a few generations ago, few women lived beyond menopause.
Itching can be caused by many conditions. A common cause of itch is psychological, that is, due to stress, anxiety, etc. Stress also can aggravate itch from other causes. Dry skin (xerosis) is another frequent cause of itch. Many people also report sunburn itch following prolonged exposure to UV radiation from the sun.
Itching can be triggered by wool fibers or irritants, such as solvents or cosmetics. Itching can result from disorders that affect the skin, the nervous system (which senses itching), or other parts of the body (such as bile ducts or kidneys) or from drugs. Causes that affect more of the body than just the skin are called systemic causes.
