Reflexology is the application of pressure to areas on the feet, hands and ears. Reflexology is generally relaxing and may be an effective way to alleviate stress.

The theory behind reflexology is that these areas correspond to organs and systems of the body. Proponents believe that pressure applied to these areas affects the organs and benefits the person's health.

Reflexologists use foot charts to guide them as they apply pressure to specific areas. Sometimes these practitioners use items, such as rubber balls, rubber bands and sticks of wood, to assist in their work. Practitioners of reflexology include chiropractors, physical therapists and massage therapists, among others.

Several studies funded by the National Cancer Institute and the National Institutes of Health indicate that reflexology may reduce pain and psychological symptoms, such as anxiety and depression, and enhance relaxation and sleep. Studies also show that reflexology may have benefits in palliative care of people with cancer.

Reflexologists claim that reflexology also can treat a wide variety of medical conditions, such as asthma, diabetes and cancer. However, scientific evidence is lacking to support these claims.

Reflexology is generally considered safe, although very vigorous pressure may cause discomfort for some people.
