WASHINGTON, DC — Stress does not always announce itself with a sudden crisis. In older adults, it can show up in everyday ways that are easy to brush off at first, from tossing and turning at night to feeling unusually tense, forgetful or withdrawn. AARP says those changes can be warning signs that stress is affecting health, not just mood.
Its 2026 survey found that among people who had experienced stress in the past 30 days, 72 percent said they were doing well managing it. But many still reported symptoms, including trouble sleeping and muscle tension, which is why experts urge people to pay attention when the pattern starts to interfere with daily life.
1. Insomnia and difficulty sleeping
One of the clearest stress signals is trouble falling asleep or staying asleep. Connecticut clinical psychologist Holly Schiff says insomnia is a classic response to stress, and the loss of sleep can create a cycle that makes the next day feel even harder. Fatigue and trouble concentrating can pile up, turning one rough night into a bigger problem.
AARP’s survey found that 63 percent of respondents had trouble sleeping, and 52 percent said they felt tired even after sleeping. Schiff suggests keeping a bedside journal to write down worries, tasks or racing thoughts before bed. The idea is to get the mental clutter out of your head so it is easier to settle down.
2. Changes in mood and thinking
Stress can also change the way people feel and think. Gail Saltz, a psychoanalyst and clinical associate professor of psychiatry at New York Presbyterian Hospital, Weill-Cornell Medical College, says rising sadness, irritability, agitation or fear can all point to stress that is becoming too much to handle. In more chronic cases, people may feel burned out, down or even numb.
Those emotional shifts often come with mental fog. Schiff says brain fog, racing thoughts, poor focus and forgetfulness are all signs to watch for. In the AARP survey, 46 percent of older adults had trouble remembering things, 44 percent felt irritable, 42 percent felt rushed, 41 percent struggled to focus and 39 percent became agitated easily.
3. Physical symptoms
Stress is not only emotional; it can also show up in the body. AARP lists headaches, upset stomach, dizziness, shaking, muscle tension and general aches and pains as common physical symptoms. Among the survey’s respondents, tense muscles were especially common, affecting 57 percent of older adults.
Experts say these symptoms happen because stress triggers the body’s hormonal and chemical response, including cortisol and norepinephrine. Saltz notes that older adults may be less likely to connect physical discomfort with stress, especially if mental health issues feel private or stigmatized. That can make the real cause easier to miss.
4. Social isolation and withdrawal
Pulling away from friends, family and ordinary routines can be another red flag. Experts say people under stress may start skipping activities they usually enjoy or avoiding social contact altogether. That kind of withdrawal can make stress, anxiety or depression feel worse over time.
Saltz says there is a difference between isolating because you are overwhelmed and taking a purposeful break to recover from burnout. Burnout is a state of physical and mental exhaustion tied to ongoing stress, such as caregiving or work. The key is noticing whether time alone is helping you reset or making symptoms deepen.
What to do when stress starts interfering
AARP says recognizing the signs early can make it easier to manage stress before it grows into a bigger health issue. Schiff and Saltz both recommend checking in with a health care provider or mental health professional if the symptoms are new, concerning or getting in the way of daily functioning. That matters because stress symptoms can overlap with other physical or mental health conditions.
The practical takeaway is simple: if sleep, mood, memory, body aches or social habits start changing at the same time, do not dismiss it. A professional evaluation can help identify the root cause and point to the right support, whether the problem is stress itself or something that looks a lot like it.
