Disorders of the Skin - Skin irritations and weather
Extremes of weather produce local inflammations and other skin problems for many people.
In cold weather, the sebaceous glands slow down the secretions that lubricate the skin, causing it to become dry. When dry skin is exposed to wintry weather, it becomes irritated and is likely to crack, particularly around the lips. Chapped skin is especially sensitive to harsh soaps. During such periods of exposure, the skin can be protected with a mild cream or lotion. A lubricating ointment should be used on the lips to prevent them from cracking. Children who lick their lips continually no matter what the weather can benefit from this extra protection. Chapped hands caused by daily use of strong soaps and detergents can be helped by the use of a lubricating cream and rubber gloves during housework.
Exposure to extreme cold for a prolonged period may cause freezing of the nose, fingers, toes, or ears, thus cutting off the circulation to the affected areas. Frostbitten areas are of a paler color than normal and are numb. They should not be rubbed with snow or exposed to intense heat. Areas should be thawed gradually, and a physician should be consulted for aftercare in extreme cases.
A localized inflammation of the skin called chilblain is common among people who are particularly sensitive to cold because of poor circulation. Chilblain may occur in the ears, hands, feet, and face, causing itching, swelling, and discoloration of the skin. Anyone prone to chilblain should dress protectively during the cold weather and use an electric pad or blanket at night. Affected parts should not be rubbed or massaged, nor should ice or extreme heat be applied directly, since these measures may cause additional damage. Persistent or extreme attacks of chilblain should be discussed with a physician.
This condition is an inflammation of two opposing skin surfaces caused by the warmth, moisture, and friction of their rubbing together. Diabetics, overweight people, and those who perspire heavily are particularly prone to chafing. Chafing is accompanied by itching and burning, and sometimes infection can set in if the superficial skin is broken. Parts of the body subject to chafing are the inner surfaces of the thighs, the anal region, the area under the breasts, and the inner surfaces between fingers and toes.
To reduce the possibility of chafing, lightweight clothing should be worn and strenuous exercise avoided during hot weather. Vaseline or a vitamin A and D ointment may be applied to reduce friction. In general, the treatment is the same as that for diaper rash in infants. If the condition becomes acute, a physician can prescribe more effective remedies.
This skin rash is usually accompanied by itching and burning. It is caused by an obstruction of the sweat ducts such that perspiration does not reach the surface of the skin but backs up and causes pimples the size of a pinhead. If the obstruction is superficial, the pimples are white; if it is deeper, they are red. The condition can be brought on by other minor skin irritations, by continued exposure to moist heat, such as a compress, or by exercise in humid weather. Infants and people who are overweight are especially prone to prickly heat.
The discomfort can be eased by wearing lightweight, loose-fitting clothing, especially at night, and keeping room temperature low. Alcoholic beverages, which tend to dehydrate the body, should be avoided. Tepid baths and the application of cornstarch to the affected skin areas will usually relieve itching. If the rash remains for several days, a physician should be consulted to make sure it does not arise from some other cause.
Calluses and Corns
As a result of continued friction or pressure in a particular area, the skin forms a tough, hard, self-protecting layer known as a callus . Calluses are common on the soles of the feet, the palms of the hands, and, among guitarists and string players, on the tips of the fingers. A heavy callus that presses against a bone in the foot because of poorly fitted shoes can be very painful. The hard surface can be reduced somewhat by the use of pumice, or by gently paring it with a razor blade that has been washed in alcohol.
Corns are a form of callus that appear on or between the toes. They usually have a hard inner core that causes pain when pressed against underlying tissue by badly fitted shoes. A hard corn that appears on the surface of the little toe can be removed by soaking for about ten minutes and applying a few drops of ten percent salicylic acid in collodion. The surface should be covered with a corn pad to reduce pressure, and the corn lifted off when it is loose enough to be released from the skin. Anyone suffering from a circulatory disease and particularly from diabetes should avoid home treatment of foot disturbances. Those with a tendency to callus and corn formations should be especially careful about the proper fit of shoes and hose. A chiropodist or podiatrist is a trained specialist in foot care who can be visited on a regular basis to provide greater foot comfort.
