Why mental health depends on physical health
Mental health is the state of well-being in which a person can realize their potential: coping with normal stress, working productively, and contributing to their community. A healthy body supports a healthy mind, and the reverse is just as true, an event that affects your physical health takes a toll on your mental health as well. Concerns about illness, treatment or surgery, family, career, cost, and pain can all lead to stress, depression, and other mental health struggles.
Because the body and mind are connected through countless networks of communication, it’s essential to care for the whole person, giving equal attention to physical and mental well-being throughout recovery.
How movement supports the mind
Vigorous physical activity has a measurable, positive impact on mental health. A 2021 study found that aerobic and resistance exercise contributed significantly to treating depression and anxiety. This is where physical therapists play a key role: they serve as a bridge between physical and mental health, encouraging patients toward physical activity as part of treatment.
Repeated physical activity increases levels of the neurotransmitter serotonin, which influences memory, learning, and mood, and a lack of serotonin plays a role in depression, anxiety, and other conditions. Even simple, repeated exercises help boost self-esteem, offering a sense of fulfillment and acceptance of new limitations. Sleep matters too: without it, stress and anxiety rise because the brain doesn’t have time to recharge, and physical activity helps the body fall asleep faster and more deeply.
Reducing isolation and restoring a sense of control
Physical therapists can also reduce the isolation that often comes with a medical concern. Having someone to talk to who genuinely cares about your health is reassuring, and working with a PT toward a clear physical therapy goal helps you regain a sense of control, which in turn reduces anxiety.
Treating the whole person
Physiotherapists working in mental health provide health promotion, preventive care, treatment, and rehabilitation for individuals as whole people, because what affects the body affects the mind, and what affects the mind affects the body. As awareness of mental health continues to grow, so does the evidence supporting physical therapy as an effective part of treatment, and more research will continue to expand what’s possible.
