The simple act of gardening may hold a surprising key to better sleep. For many, tending a garden is a relaxing hobby, a chance to connect with nature and enjoy the fruits – or vegetables, or flowers – of their labor. But a growing body of research suggests the benefits extend beyond stress relief and fresh produce, potentially reaching into the realm of restorative sleep.
A recent study published in the Journal of Affective Disorders adds to this evidence, finding that individuals who regularly engage in gardening activities reported fewer sleep complaints. This includes difficulties with sleep duration, symptoms of sleep apnea, insomnia, and even daytime fatigue. The findings underscore the importance of lifestyle factors – alongside nutrition and exercise – in achieving quality rest, a cornerstone of overall health.
“We know that sufficient sleep is one of the three pillars of a healthy lifestyle along with nutrition and exercise,” explains Dr. Fariha Abbasi-Feinberg, M.D., a sleep specialist and spokesperson for the American Academy of Sleep Medicine (AASM). “Insufficient sleep contributes to the risk of other chronic medical problems.” Chronic sleep deprivation is linked to an increased risk of depression, anxiety, impaired memory, and a weakened immune system. Prioritizing sleep allows the body and brain to recharge, regulating metabolism and bolstering defenses against illness. Practicing good sleep hygiene can further reduce the risk of chronic pain and even certain cancers.
How Gardening May Improve Sleep
The study, which analyzed data from nearly 60,000 participants in the 2017 Behavioral Risk Factor Surveillance System (BRFSS), revealed a statistically significant association between regular gardening and a lower likelihood of experiencing multiple sleep-related issues. Researchers found that gardeners were less likely to report short sleep duration, sleep apnea, insomnia, and excessive daytime sleepiness.
Dr. Abbasi-Feinberg, who is also an avid gardener herself, acknowledges the promising findings but emphasizes the require for further research. “As a sleep doctor and avid gardener, I find joy in the idea that gardening benefits sleep,” she says. “Yet, while it compares positively to no exercise, the data I have access to lacks sufficient detail to gauge its efficacy against other forms of physical activity. This actually raises more questions, whether the results are due to being outside in nature versus connecting with the soil and plants or the physical activity of gardening.”
The benefits likely stem from a combination of factors. Exposure to natural light during the day helps regulate the body’s circadian rhythm, the internal clock that governs sleep-wake cycles. Physical activity, even moderate gardening, can promote deeper and more restful sleep. The act of gardening itself can be meditative and stress-reducing, creating a mental state conducive to sleep. Studies have also shown a correlation between access to green spaces and improved sleep duration, suggesting that simply being in nature can be beneficial.
The Broader Benefits of Time Outdoors
The positive impact isn’t limited to those with a green thumb. “This study seems to indicate being physically active and being outside in nature may assist overall sleep health,” Dr. Abbasi-Feinberg notes. Even a simple walk in a park or spending time in a natural setting can offer similar benefits. We find numerous health benefits of spending time in nature, including reduced stress, improved concentration, and a greater sense of well-being. Being outdoors also encourages physical activity, even if it’s just walking and exploring.
The connection between nature and mental health is increasingly recognized. Research suggests that exposure to natural environments can lower cortisol levels (a stress hormone), boost the immune system, and improve cognitive function. These effects, in turn, can contribute to better sleep quality. Some studies have even demonstrated improvements in dementia symptoms among individuals who regularly engage in gardening activities.
What Does the Science Say About Green Spaces and Sleep?
The link between green spaces and sleep isn’t new. A 2015 study published in Environmental Health Perspectives found that people living in areas with more green space reported fewer depressive symptoms and better sleep quality. Researchers theorized that this was due to a combination of factors, including reduced noise pollution, increased opportunities for physical activity, and a stronger sense of community.
Another study, published in Landscape and Urban Planning in 2017, examined the relationship between residential greenness and sleep duration in a large sample of adults. The findings revealed that individuals living in greener neighborhoods tended to sleep longer and experience fewer sleep disturbances.
While the exact mechanisms underlying these associations are still being investigated, the evidence suggests that incorporating more nature into our daily lives – whether through gardening, spending time in parks, or simply taking a walk outdoors – can have a positive impact on both our physical and mental health, including the quality of our sleep.

Researchers continue to explore the complex interplay between lifestyle factors and sleep health. Future studies will likely focus on identifying the specific components of gardening – physical activity, exposure to sunlight, connection with nature, mindful engagement – that contribute most to improved sleep. For now, the evidence suggests that getting your hands dirty in the garden could be a surprisingly effective way to cultivate a more restful night’s sleep.
