A new study from the University of Pittsburgh has found that older adults who often feel very tired may face a higher risk of dying within a few years. The research shows that people aged 60 and older who report high levels of fatigue are more than twice as likely to die within the next 2.7 years compared to those who feel less tired.
Fatigue is more than just feeling sleepy—it’s a strong sense of physical exhaustion, especially after doing regular activities like walking, gardening, or light housework. This study is the first to clearly link that type of physical tiredness to a greater chance of early death.
The research team used a tool called the Pittsburgh Fatigability Scale to measure how tired people felt after different levels of activity. This scale was developed in 2014 and has become widely used around the world. It’s now available in 11 languages and helps doctors and researchers better understand how fatigue affects older adults.
The study involved nearly 3,000 people, all part of the Long-Life Family Study, which looks at health and aging in families with a history of long life. Participants were asked to rate how tired they would feel after different everyday tasks. Each task was scored from 0 (not tired at all) to 5 (extremely tired), and the total score gave a measure of their physical fatigability.
After analyzing the results and considering other health factors, the researchers found something striking: people who scored 25 or higher on the fatigability scale were 2.3 times more likely to die in the next few years than those with lower scores. This finding was not explained by age alone—it showed that severe fatigue is a warning sign of serious health risks.
This research is important because it shows that monitoring how tired an older person feels after normal daily activities could help spot health problems early. Fatigue may be a sign that the body is struggling, even before major illness shows up.
The study adds to what we already know about healthy aging. Past research has shown that regular physical activity can help reduce tiredness, improve mood, and boost energy levels. This new study strengthens that message, suggesting that staying active might not only improve quality of life but also extend it.
Of course, not all fatigue is the same. It’s normal to feel tired now and then, especially after a busy day. But when tiredness becomes frequent or severe, it may be a sign that something deeper is going on—whether it’s a heart issue, poor nutrition, lack of movement, or another hidden health condition.
The Pittsburgh Fatigability Scale could be a helpful tool for doctors to use during regular checkups. It gives a quick picture of how an older adult is coping with daily life and might help guide decisions about lifestyle changes, medical tests, or extra support.
This study, published in The Journals of Gerontology: Series A and led by Dr. Nancy W. Glynn, is a reminder that fatigue should not be ignored in older adults. Feeling extremely tired after small amounts of activity could be an early sign of declining health—and catching it early might save lives.
In short, listening to the body and paying attention to signs of tiredness in older age is more important than many people realize. It could be the key to living not just longer, but better.
