Early in the COVID-19 pandemic in the United States, as lockdowns put millions out of work and headlines forecast food shortages, anxious Americans picked up their rakes and spades.

Many people were cut off from social gatherings. They were worried about bare shelves and contaminated grocery stores. And they needed something to occupy schoolchildren.

In response, record numbers of people began cultivating coronavirus victory gardens. In a matter of weeks, seeds, seedlings, and fruit trees sold out online and in gardening centers.

As it turns out, the impulse to garden is actually a great idea — whether or not you’re coping with a crisis — because gardening is one of the healthiest hobbies you can develop. Keep reading to learn about the many benefits of gardening, for you and your community.

Outdoor gardening can help your body fight disease

You’re more like a plant than you may realize. Your body is capable of photosynthesis — the process where plants make their own food using sunlight.

Your skin uses sunlight to make one of the nutrients you need: vitamin D. ResearchersTrusted Sourceestimate that a half hour in the sun can produce between 8,000 and 50,000 international units (IU) of vitamin D in your body, depending on how much your clothes cover and the color of your skin.

Vitamin D is essential for literally hundreds of body functions — strengthening your bones and your immune system are just two of them. StudiesTrusted Source have also shown that being out in the sun can help lower your risk of:

If your vitamin D levels are low, you have a greater risk of developing psoriasis flares, metabolic syndrome (a prediabetes condition), type II diabetes, and dementia, as well.

All of these factors have to be balanced against the risk of skin cancer from overexposure to the sun’s rays, of course. But the science is clear: A little sunshine in the garden goes a very long way in your body.

Gardening builds strength, promotes sleep, and helps you maintain a healthy weight

The Centers for Disease Control and Prevention (CDC)Trusted Source says gardening is exercise. Activities like raking and cutting grass might fall under the category of light to moderate exercise, while shoveling, digging, and chopping wood might be considered vigorous exercise.

Either way, working in a garden uses every major muscle group in the body. This fact won’t surprise anyone who’s woken up sore after a day of yardwork.

Studies have found that the physical exertion of working in a garden may help offset both age-related weight gainTrusted Source and childhood obesityTrusted Source. And researchers at the University of Pennsylvania reported that people who garden are more likely to get a solid 7 hours of sleep at night.

Gardening can help protect your memory as you get older

Doctors have also known for some time that exercise improves cognitive functioning in the brain. There’s some debate about whether gardening on its own is enough to affect cognitive skills like memory. But new evidence shows that gardening activities may spur growth in your brain’s memory-related nerves.

Researchers in Korea gave 20-minute gardening activities to people being treated for dementia in an inpatient facility. After the residents had raked and planted in vegetable gardens, researchers discovered increased amounts of some brain nerve growth factors associated with memory in both males and females.

In a 2014 research review, analysts found that horticultural therapy — using gardening to improve mental health — may be an effective treatment for people with dementia.

In fact, in the Netherlands and Norway, people with dementia often participate in groundbreaking Greencare programs, where they spend a large part of the day working on farms and in gardens.

Gardening is a mood booster

Studies in the United States and abroad have found that gardening improves your mood and increases your self-esteem. When people spend time in a garden, their anxiety levels drop and they feel less depressed.

In a multi-year study published in 2011Trusted Source, people with depression participated in a gardening intervention for 12 weeks. Afterward, researchers measured several aspects of their mental health, including depression symptoms, finding that all of them were significantly improved. And those improvements lasted for months after the intervention ended.

Gardening calms you after stressful events

Working in a garden can help you recuperate if you’ve experienced something stressful.

In a 2011 study, researchers exposed study participants to a stressful activity. Then they asked half the group to spend time quietly reading and the other half to spend time gardening.

When researchers tested the levels of the stress hormone cortisol in their bodies, they found that the gardening group had recovered from the stress better than the reading group. The gardening group also reported that their moods had returned to a positive state — while fewer of the readers had.

Key takeaways

Gardening invites you to get outside, interact with other gardeners, and take charge of your own need for exercise, healthy food, and beautiful surroundings.

If you’re digging, hauling, and harvesting, your physical strength, heart health, weight, sleep, and immune systems all benefit. And those are just the physiological outcomes. Gardening can also cultivate feelings of empowerment, connection, and creative calm.

Whether your patch is large or small, a raised bed, community garden, or window box, getting dirty and eating clean are good for you.
