Nature-connectedness practices are broader than simply taking a walk in a park. They involve deliberately paying attention to and engaging with the natural environment, whether that means walking among trees, sitting beside water, gardening, watching wildlife, spending time in a local park, or simply slowing down enough to notice natural sights, sounds and sensations.
For sleep, however, we need to make an important distinction. Most research has studied exposure to green space or nature-based activities rather than "nature connectedness" itself. In other words, the evidence is stronger for spending time in nature than for the claim that developing a deeper emotional relationship with nature independently improves sleep.
A systematic review examining 13 studies of green-space exposure and sleep found that 11 reported associations with better sleep quality, sleep quantity, or both. The studies ranged from residential green-space research to interventions involving walking, gardening and forest environments. That is an encouraging pattern, but much of the evidence was observational, so greener surroundings cannot automatically be assumed to be the cause of better sleep. People living near green space may also experience differences in exercise, noise, air pollution, socioeconomic circumstances and daily routines.
Some experimental research gives the idea more weight. In a randomized study of university students, participants completed mindful walking either in a natural environment or an urban environment. Sleep quality improved over the intervention period, alongside changes in mood and mindfulness. Interestingly, improvements were not confined exclusively to the nature group, suggesting that walking and mindful attention themselves may contribute substantially to the benefit. Nature may enhance the experience without necessarily being the only active ingredient.
A small crossover experiment produced an intriguing physiological finding. Thirteen adults completed the same-length lunchtime walk in both a natural and a built environment. During subsequent sleep, measures of heart-rate variability associated with parasympathetic activity were higher after the nature walk. The study was very small and did not establish that participants actually slept longer or better, but it suggests that daytime exposure to nature may influence nighttime physiological recovery rather than acting only as a pleasant distraction.
Forest walking has also been studied in people who already reported sleep difficulties. In a 2011 before-and-after study, participants completed approximately two hours of forest walking. Actigraphy suggested longer sleep afterward, while subjective sleep depth and sleep quality also improved. Anxiety decreased as well. Because there was no randomized non-forest control condition, it is impossible to know how much of the result came from the forest itself, the exercise, time outdoors, reduced stress, daylight exposure, or simply spending two hours away from normal demands.
That combination of mechanisms is actually one of the strengths of nature-based practices. Going outside can simultaneously increase daytime light exposure, encourage physical activity, reduce sedentary screen time, provide psychological distance from work and responsibilities, and expose someone to a quieter or more restorative environment. All of those factors can potentially influence sleep. It may therefore be misleading to search for one special "nature pathway" when the benefit could arise from several changes happening together.
Nature connectedness may add another layer. People who feel more connected with nature tend to report greater positive affect, vitality and life satisfaction, although those findings are primarily about well-being rather than sleep. A meta-analysis involving more than 8,500 people found a small but significant relationship between nature connectedness and measures of happiness and well-being. That supports the psychological value of developing an active relationship with nature, but it does not demonstrate that feeling connected to nature directly treats insomnia.
Practically, this means the strategy does not need to involve remote wilderness or formal "forest bathing." In the United States, it might mean spending regular time in a neighborhood park, state park, garden, wooded trail, lakeside area, beach, or simply an outdoor space with trees and vegetation. Someone living in a city can still practice nature connectedness by deliberately noticing seasonal changes, bird activity, clouds, trees, flowers, wind, sunlight or water rather than treating the outdoor environment merely as somewhere to pass through.
The same principle applies in the UK through local parks, public footpaths, woodland, canals, commons, coastlines, gardens and National Trust or Forestry England locations. The important variable is meaningful contact with nature, not whether the setting qualifies as wilderness.
A simple practice might be 20 to 30 minutes outdoors during the day, ideally incorporating some walking and daylight. Instead of listening to a podcast or looking at a phone throughout the entire period, spend at least part of the time deliberately noticing what is around you: temperature, wind, birdsong, trees, water, changing light or seasonal details. Gardening, sitting outdoors or spending quiet time in a green space may provide similar opportunities for someone who does not want or cannot manage a longer walk.
There is no established sleep-specific dose showing that exactly 20, 30 or 120 minutes in nature is optimal. Nor is there good evidence that a particular practice such as forest bathing is uniquely superior to ordinary time spent outdoors. The strongest evidence supports the broader pattern of green-space exposure and nature-based activity.
Nature-connectedness practices therefore deserve a place in the library, but not because science has shown that "connecting with nature cures insomnia." The evidence is more interesting than that. People with greater exposure to green environments often sleep better, several nature-based interventions have produced improvements in sleep or nighttime recovery, and nature can simultaneously influence stress, activity, daylight exposure and mental disengagement. What remains uncertain is how much benefit comes specifically from nature itself rather than from the healthy behaviors that often accompany spending time there.
