New research led by the University of Plymouth has found that exposure to green spaces and nature is associated with lower cravings for cigarettes, alcohol, and unhealthy food choices. This is the first study to reveal that passive exposure to close green spaces is linked to not only lower frequency of cravings, but also the strength of those cravings.
This study builds on earlier research which suggested that exercising in nature can also reduce cravings. This new study demonstrates the same may also be true even irrespective of any physical activity.
The findings add to increasing evidence that points to the need to invest and protect green spaces within cities and towns. These investments help maximize public health benefits that people can afford. The current study also suggests the causality link of this needs to be better investigated.
The research is the first to study the relationship between people’s exposure to natural environments, experiencing negative feelings or emotions, and cravings for a range of appetite substances. The study involved academics from the School of Psychology with included support from the European Centre for Environment and Human Health at the University of Exeter.
It has been known that being outdoors in nature is associated to a person’s well being. However, the possibility of a similar link with cravings from just being able to see green spaces, adds a new dimension to the previous research. The study could have a range of possibilities for environmental protection programs and public health in the future.
For the study, the participants completed an online survey which explored relationships between a variety of nature exposure and cravings. It measured the proportion of green space which was located in a person’s residential neighborhood, the amount of green views that was seen from their home, their access to an allotment or garden, and also the frequency to which they visited public green spaces.
The results indicated that people who have access to an allotment or garden were associated with both reduced cravings strength and frequency. Residential views which incorporated more than 25% of green space showed similar responses.
The study additionally measured physical activity that was undertaken within the identical time frame as the cravings were assessed. This part of the study also indicated reduced cravings occurred irrespective of physical activity levels.
Cravings contribute to a host of health damaging behaviors such as excessive drinking, smoking, and the consumption of unhealthy foods. As a result, these cravings contribute to some of the most challenging global health issues of our time. This includes obesity, diabetes and cancer. Showing that more exposure to green spaces is associated with lower cravings can prove to be promising for future public and private programs and individual health.

Natural environments and craving: The mediating role of negative affect
The risk of dementia may be influenced long before symptoms appear. New research suggests that avoiding three key midlife risks could help extend the number of years people live without dementia. Those free of all three risk factors experienced roughly 13 additional dementia-free years compared with people affected by all three.
While it’s well known that processed foods can harm health, a new study reveals the problem runs deeper than just excess calories, refined carbs, or unhealthy fats. Researchers found that certain preservative additives are independently associated with increased risk of high blood pressure and cardiovascular disease.
A slower walking pace is a common part of aging, but the reason may be more complex than previously thought. New findings suggest that older adults unconsciously prioritize staying upright and stable, even if it requires more effort and energy. Although this shift may help maintain balance, researchers found that it can also lead to slower walking speeds, greater fatigue, and a heightened susceptibility to falls.
