Not a fancy way of saying "everything a person does in a day." Usually, the phrase means the basic self-care tasks a person must be able to handle to live independently. That includes things like bathing, dressing, eating, using the bathroom, getting in and out of bed or a chair, and moving around safely. Some providers also talk about more complex tasks - shopping, cooking, driving, or managing money - but those are often separated out as instrumental activities rather than core daily living activities.

The phrase matters because it gives doctors, therapists, insurers, and courts a practical way to measure how badly someone is hurt and how much help they need. A person may be able to walk into an exam room yet still struggle with showering, climbing stairs, or putting on socks. Those limits can say more about real-world function than a scan or a brief office note.

In an injury claim, trouble with activities of daily living can affect the value of damages, the need for future medical care, and whether someone has a partial or total disability. In Missouri, records from treating providers and rehabilitation specialists can be especially important in workers' compensation and personal injury cases. If an insurance company downplays those day-to-day limits, it may also downplay pain, lost independence, and the true cost of recovery.
