Make Your Year-Round Hobby a Seasonal Outdoor Adventure

Here's a number that should stop you in your tracks: 24%. That's the reduction in all-cause mortality associated with any outdoor gardening activity in a nationwide cohort of 13,812 US adults followed for a median of 16.8 years (Liang et al., NHANES gardening, 2024). Not a 2% blip, not a 5% trend—a 24% lower risk of dying from anything, with even larger reductions for cardiovascular (35%) and respiratory (34%) mortality. If a pill did that, we'd be popping it daily. But we're not; we're scrolling on our phones. This is why I'm convinced that the best year-round hobby is a seasonal outdoor adventure—not a token hike in July, but a commitment to getting outdoors in every season, at a dose that actually matters.

Why Outdoor Adventures Beat Indoor Hobbies—But Only at the Right Dose

I'm not anti-indoor. I love a good crossword as much as the next person—and the evidence is strong that crosswords can slow cognitive decline in mild cognitive impairment (Devanand et al., NEJM Evidence, 2022). But when it comes to overall wellbeing, outdoor activities have a unique edge: they combine physical activity, nature exposure, and often social connection. The problem is that most people treat the outdoors like a once-a-year vacation, not a year-round habit. And the science is clear that dose matters. A meta-analysis of forest therapy found that 30- and 60-minute sessions produced significant mood improvements, while 15-minute sessions did not (Front Psychol, 2025). In other words, a quick stroll past a tree isn't enough. You need to stay out there—at least half an hour—to get the benefit.

The Case for Year-Round Gardening

If I had to pick one outdoor hobby to recommend above all others, it would be gardening. Not only does it get you outside, but it's also a full-body activity that can be adapted to any season—from spring planting to winter planning. The NHANES study showed that any outdoor gardening was linked to a 24% lower risk of death, and the more you did it, the better the effect (Liang et al., 2024). A separate meta-analysis of 22 studies found that gardening reduced depression and anxiety, and increased life satisfaction and sense of community (Soga et al., Preventive Medicine Reports, 2017). And here's the kicker: gardening is not just a summer thing. In winter, you can build cold frames, force bulbs indoors, or plan next year's layout. The point is to keep your hands in the soil—or at least your mind in the garden—year-round.

Addressing the Counterargument: But It's Cold and Dark in Winter

The biggest objection to year-round outdoor hobbies is the weather. In winter, daylight shrinks, and in places like Hobart, Australia, it drops from 15 to 9 hours—which is why seasonal affective disorder affects up to 9% of the population there (ABC News Australia, 2025). It's a legitimate concern. But here's the thing: the evidence suggests that outdoor light exposure and exercise are precisely what help combat the winter blues. A randomized trial found that aerobic exercise, with or without bright-light exposure, relieved depressive symptoms compared to a control group (Leppämäki et al., J Clin Psychiatry, 2002). And a systematic review of lifestyle modifications for SAD identified outdoor sunlight exposure and exercise as effective interventions (J Psychosom Res, 2024). So instead of hibernating, you should be bundling up and getting outside. The key is to choose activities that work in your climate—snowshoeing, winter hiking, or even just a brisk walk during the limited daylight hours.

How to Make Outdoor Adventures Stick Year-Round

The challenge with any hobby is consistency. The research on leisure crafting shows that approaching hobbies more meaningfully—with goal-setting, learning, and social connection—can boost their benefits (EurekAlert, 2024). So here's my advice: pick one outdoor activity you love, set a specific goal (like growing your own tomatoes or hiking a certain trail each month), and find a community. A study of 3,545 knitters found that group knitting improved happiness and social contact (Riley et al., 2013), and the same principle applies to outdoor clubs. Also, remember that variety helps: a study of older adults found that a greater variety of social activities was linked to lower mortality (HRS bibliography, 2024). So mix it up—gardening in spring, hiking in summer, leaf-peeping in autumn, and snowshoeing in winter.

Quick Tip

Start with just 30 minutes of outdoor activity, three times a week—that's the minimum dose that forest therapy research suggests for mood benefits (Front Psychol, 2025).

The Bottom Line

Outdoor adventures are not just a nice-to-have; they're a health imperative. The evidence is overwhelming that time in nature, at the right dose, can lower your risk of death, boost your mood, and keep your brain sharp. So this year, make a commitment: choose an outdoor hobby that you can adapt to every season, and stick with it. Your future self will thank you.
