Aging affects the entire body, including sense organs. Vision, hearing, taste, smell and touch are beginning to weaken. How fast and far-reaching of these changes will largely determine the future life.
Vision
Around 30-40 years old pupils are beginning to narrow, and the lens of the eye becomes denser and loses its transparency. This reduces the amount of light reaching the retina. To see well, eyes 60-year-old man to 3 times more light than the eyes of youth. Typically, the first symptom of the changes is the deterioration of vision in the dark. In this case, may have to give up driving at night.
The muscles that help to focus the eye, gradually begin to lose their elasticity. After 40 may not be able to focus on close objects and the need for reading glasses.
Glaucoma and retinal dystrophy - the main causes of blindness in old age. With both diseases, to some extent can be combated. So after 40 years is particularly important to regularly visit an ophthalmologist.
Hearing
About a third of Americans older than 60 years and half of Americans over 85 suffer some degree of hearing loss.
The main cause of hearing loss - damage to the delicate hairs of the inner ear, which send signals to the brain. Loud noises, inner ear infection and fever of accelerating this process. First, usually deteriorates the ability to hear high-pitched sound, as well as the ability to follow a conversation in the presence of background noise.
Education in the ear plugs sulfur - another reason for the deterioration of hearing. As we age, degenerative changes occur in the sweat glands, namely, their isolation makes ear sulfur soft. Denser earwax can block the transmission of sound waves, and the sounds will seem muted.
"Ringing in the ears appears when the hairs in the inner ear are damaged and the brain sends electrical signals that are interpreted as sound.
Taste and smell
Very often we confuse the taste and smell. Approximately 80 percent of the problems that we feel connected with taste, in fact, belong to the sense of smell.
Taste - some of the most powerful. Man is born with about 10 000 taste buds on your tongue. After 50 we start to lose some of them. As a young man distinguishes five different tastes: sweet, sour, salty, bitter and astringent (minds). With age, the sweet beginning to be felt more strongly acidic and slightly weaker.
Sense of smell helps to distinguish smells. Try to smell chocolate. The taste is sweet and slightly bitter, but she has absolutely no smell.
Approximately 30% of people aged 70-80 years have problems with smell. Loss of smell may be total or partial, may also change the perception of smells. For example, a person can feel horrible smell, when in fact it does not, or strawberries may suddenly lose its flavor. Sometimes this leads to depression.
Return the sense of smell or taste in most cases impossible. The risk increases if a person smokes or not caring for their teeth. Polyps in the nose can also block odors. Worsen the ability to receive medications, head injuries and some diseases.
Touch
With age, skin becomes drier, thinner and less elastic, and placed it in the nerve cells - are less sensitive. Could change the sensitivity to changes in temperature. Various diseases, such as the deterioration of blood circulation or nerve damage from diabetes also lead to a deterioration of touch.
