Age-related hearing loss, or presbycusis, is the slow loss of hearing that occurs as people get older. Tiny hairs inside your ear help you hear. They pick up sound waves and change them into the nerve signals that the brain interprets as sound.

Sensorineural hearing loss results when there is a problem with the inner ear. It most often occurs when the tiny hair cells (nerve endings) that transmit sound through the ear are injured, diseased, do not function properly, or have prematurely died. This type of hearing loss is sometimes called "nerve damage," although this is not accurate.

Scientists at the University of Shizuoka School of Pharmaceutical Sciences state that “>a href="http://www.invitehealth.com/green-tea-extract/womens-vitamins/">Green Tea is known to contain antiviral components that prevent influenza infection”. 2663 schoolchildren between the ages of 6 to 13 from a variety of elementary schools in a tea plantation region (Kikugawa City) were studied each year in 2008 and 2009. The incidence of the flu confirmed by a test for children consuming Green Tea for 6 or 7 days a week was 40% lower than for children who consumed Green Tea less than 3 days a week.

The CARDIA study consists of 5115 young adults who completed clinical examinations in the years 1985-1986. They then had subsequent examinations 6 times over the next twenty years. Drinking tea but not coffee or caffeine reduced the risk of having calcified plaque in the coronary artery and slowed its progression.
