Electromagnetic spectrum refers to the full range of all frequencies of electromagnetic radiation and also to the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Devices used to measure an electromagnetic spectrum are called spectrograph or spectrometer.
Another way that alcohol affects the endocrine system is by interfering with how the body absorbs calcium, a chemical needed for strong bones. As a result, people who drink heavily may be at a higher risk for osteoporosis, a disease in which bone density declines.
Estrogen deficiency accelerates bone remodeling and leads to an imbalance in remodeling. Alcohol might reduce bone loss in postmenopausal women by increasing the circulating levels of estrogen, or by acting on bone cells to reduce bone remodeling. Decreased bone density increases the risk for osteoporosis.
