Activities of daily living, or ADLs as health-care providers may refer to them, include bathing, grooming, dressing, sleeping, mobility, and eating. These are self-care tasks people perform for themselves each day. The ability or inability to perform any of these ADLs provides a measure of the effect of a disorder or disease's process. With aging, many ADLs naturally become more difficult to perform. As individuals loose the ability to perform ADLs, the higher the level of assistance they may require, if only to be safe.
