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.
Alcohol can also increase the release of beta-opioid-endorphins from the brain and stimulate prolactin release 53, both of which can negatively affect testosterone production. Oxidative damage increases thorough the body in response to alcohol consumption 54, this leading to localized reduction of testosterone in the gonads and also indirect reduction via increased cortisol levels.
