I know it, you know it, we all know it — skiing makes you feel good. But the mental health benefits of skiing go far deeper than the endorphin rush of a good run. Science is now telling us that a physically active skiing lifestyle may be one of the most powerful things you can do for your long-term brain health.
The most compelling research comes from a remarkable long-term project by brain researchers at Lund University and Uppsala University in Sweden, who have spent decades studying the health outcomes of participants in Vasaloppet — the world’s oldest and largest cross-country ski race, held annually in Sweden since 1922. The researchers compared approximately 200,000 people who competed in Vasaloppet between 1989 and 2010 with an equally large control group from the general Swedish population. What they found across multiple published studies is striking.
Depression: By the end of the study period, only 1,030 Vasaloppet skiers had developed depression — compared to 2,045 people in the control group. Skiers were half as likely to be diagnosed with depression as their non-skiing counterparts. For men specifically, faster finishing times correlated with even lower depression risk. Among women, all skiers showed lower depression rates than the general population regardless of performance level.
Vascular Dementia: Two decades after competing, only 233 Vasaloppet skiers had developed dementia compared to 319 in the general population. When broken down by type, skiers were 50% less likely to develop vascular dementia — the type caused by impaired blood flow to the brain, often triggered by stroke. Importantly, however, researchers found no significant reduction in the risk of Alzheimer’s disease. “The results indicate that physical activity does not affect the molecular processes that cause Alzheimer’s disease, such as the accumulation of the amyloid protein,” said Professor Oskar Hansson, memory researcher at Lund University. “Nonetheless, physical activity reduces the risk of vascular damage to the brain, as well as to the rest of the body.”
Anxiety: A follow-up study published in Frontiers in Psychiatry in 2021 — using the same Vasaloppet cohort of nearly 400,000 people followed for up to 21 years — found that skiers had approximately 60% lower risk of being diagnosed with anxiety disorders compared to non-skiers, regardless of age, education level, or sex. The study was picked up by the New York Times and CNN and remains one of the largest studies ever conducted on physical activity and anxiety.
Parkinson’s Disease: Among Vasaloppet participants, only 119 were diagnosed with Parkinson’s disease compared to 164 in the general population. “It seems that those who are physically active have a ‘motor reserve’ that postpones the onset of the disease,” said doctoral student and study author Tomas Olsson. “If a person trains a lot it may be possible to maintain mobility for longer despite the pathological changes in the brain.”
“As brain researchers, we have had the unique opportunity to analyze an exceptionally large group of very physically active people over two decades,” said research team leader and Lund University professor Tomas Deierborg. “We have unravelled some interesting results.”
What is important to point out is that the Vasaloppet research is observational, not experimental — meaning it shows correlation, not causation. Professor Deierborg himself is careful on this point: “One must remain humble when interpreting the data, as we do not show any causality.” It is possible that people who choose to participate in long-distance ski races are already predisposed to better health outcomes through factors the study does not control for.
That said, the scale of the research — nearly 400,000 people, tracked for up to two decades — is exceptionally robust by the standards of epidemiological research. And the findings are consistent across depression, anxiety, vascular dementia, and Parkinson’s, which strengthens the case that physical activity is the mechanism rather than a confounding variable.
Beyond the Vasaloppet research, a growing body of evidence supports the mental health benefits of time spent in nature. A study published in Applied Research in Quality of Life surveyed 279 visitors at three major ski resorts and found that the experience of skiing significantly increased overall happiness and reported wellbeing — a finding consistent with broader ecotherapy research showing that time outdoors in natural environments lowers cortisol levels, reduces blood pressure, and improves mood.
Skiing also induces what psychologists call a flow state — the condition of complete absorption in a challenging physical task — which is associated with reduced anxiety, improved self-esteem, and heightened feelings of competence and control. The technical demands of skiing, which require continuous focus on terrain, speed, and body position, are particularly well-suited to producing this state. It is arguably one of the few recreational activities that forces genuine mindfulness by making distraction physically dangerous.

The science of skiing and brain health is still developing, and the Vasaloppet researchers are the first to acknowledge that much remains to be understood about the mechanisms involved. But the evidence base from this study is large enough — and consistent enough — to say something meaningful.
Skiers are significantly less likely to develop depression, anxiety, vascular dementia, and Parkinson’s disease than their non-skiing counterparts. The protective effect appears strongest for vascular brain health and mood disorders. And while skiing cannot yet be claimed as a defence against Alzheimer’s specifically, it is a powerful tool for the kinds of brain health that are within our reach to influence.
So the next time someone questions whether your lift pass is a justifiable expense, you have a peer-reviewed answer: it is a long-term investment in your mental health.
