What about allergic reactions in the skin?
Allergic skin disorders in older individuals, which may arise from contact with or ingestion of offending allergens, must be distinguished from other causes, such as dry skin.
Discontinue the use of products, such as topical alcohol and strongly scented soaps that may further dry the skin. It is also helpful to limit bathing to every other day, up to a maximum of once a day (because too much water can actually cause the skin to dry out), using tepid or cool water; therefore, showering or bathing more than once a day should be avoided to prevent dry skin. Control of the environment is also important.
Dry skin is often a problem in cooler climates, especially during winter months, when home heating systems are regularly used. This dry heat draws moisture from the skin. Outdoors, cold winter air causes the body to protect itself by drawing blood away from the skin. When this occurs, the skin is not well nourished, and dry skin and itching can result. Consequently, the indoor environment should be cool and vapor humidified, and your exposure to cold temperatures and wind should be limited.
Temperature regulation is a major concern. People need to sense hot and cold and other changes in order to take appropriate preventive measures to maintain homeostasis. Being able to detect when you are cold is essential for survival! Nails undergo a slow decline in growth, with thinning of the nail plate and ridging and splitting.
