Loneliness recognized as health risk with nature-based remedies

Loneliness and social isolation are increasingly recognized as significant public health risks, with the U.S. Surgeon General previously comparing the impact of chronic isolation to smoking 15 cigarettes a day. Research indicates that nearly one in three American adults experiences frequent loneliness, which is linked to various health issues including depression, chronic pain, fatigue, insomnia, cardiovascular disease, stroke, and cognitive decline in older adults.

Loneliness is defined as a subjective disconnect between an individual's social expectations and their reality, meaning it can be felt even when surrounded by others. This state can trigger a permanent stress response, leading to elevated hormones and inflammation.

New research suggests that nature-based social prescribing—where clinicians prescribe activities such as gardening, hiking, or birdwatching—may offer lasting relief. A study published in Lancet Regional Health, involving participants in Barcelona, found that engaging in nature-based activities, especially with others, can significantly reduce feelings of loneliness.
