Greenspace Exposure Enhances Gut and Skin Microbiota Health In Adults, Elderly & Children

Greenspace exposure enhances the health of gut and skin microbiota. A study has found that exposure to greenspaces, which are areas of natural vegetation, significantly boosts the health of the gut and skin microbiota in adults.

The gut microbiota, also known as the gut flora, is a complex community of microorganisms living in our intestines. These microorganisms are essential for digestion, immune function, and even mental health. They influence various aspects of our health, including the development of allergies, obesity, and mental disorders. Similarly, the skin microbiota, which consists of microorganisms residing on the skin’s surface, plays a vital role in skin health, immune function, and the development of skin conditions.

The specific types of greenspaces studied included parks, forests, gardens, and grasslands. These greenspaces were evaluated across different geographic contexts, including multiple countries in Europe, North and South America, Oceania, and Asia. The study aimed to determine whether residential greenness was associated with microbial diversity and composition in these areas, and whether greenness exposure was linked to the abundances of specific genera within the microbiota.

Greenspaces can have a profound effect on the composition and diversity of both the gut and skin microbiota. Greenspaces offer a variety of environmental conditions, such as different temperatures, humidity levels, and exposure to various chemicals. These conditions can stimulate the growth and diversification of microbial communities, leading to a healthier microbiota.

Regular exposure to greenspaces can lead to an increase in the diversity of gut and skin microbiota. This diversity is associated with improved health outcomes, including better digestion, stronger immune responses, and healthier skin. The study also noted that the health benefits of greenspace exposure are not limited to adults but can also be beneficial for children and the elderly, study.

Greenspace Exposure Enhances Gut and Skin Microbiota Health – Findings By Studies

A study published by the National Center for Biotechnology Information (NCBI) found that higher residential greenness levels were associated with a higher diversity of skin and gut microbiota, which is essential for immune regulation and protecting against inflammatory disorders. The study also found that the diversity of skin and gut microbiota is affected by environmental exposures, including greenspaces.

The Oxford Academic study suggests that the natural environment is a reservoir of genetic and metabolic diversity that fine-tunes regulation of the immune system, while modern medicine and the urban lifestyle reduce human contact with organisms from other humans, animals, and the natural environment, compromising regulation of the immune system and increasing the prevalence of chronic inflammatory disorders.

One NCBI study also found that the skin microbiome has greater variability over time than the gut, suggesting that it may be modified more readily by environmental exposures, such as personal contact, changes in environment, and even space travel by astronauts.

Potential Risks Or Downsides To Regular Exposure To Greenspaces

While the benefits of greenspace exposure on health outcomes, including the enhancement of gut and skin microbiota, are well-documented, it’s important to consider potential risks or downsides associated with regular exposure to greenspaces.

Allergens and Pollen: Greenspaces, especially those with a variety of plant species, can be a source of allergens and pollen. Individuals with allergies may experience discomfort or symptoms when exposed to these substances.

Pathogens: Like any outdoor environment, greenspaces can harbor pathogens, including bacteria, viruses, and fungi. While these pathogens are generally present in low concentrations and are part of the natural ecosystem, individuals with compromised immune systems may be more susceptible to infections.

Insects and Pests: Greenspaces can attract various insects and pests, which can pose a risk to human health, especially for individuals with allergies or sensitivities to certain insects.

Physical Risks: While not directly related to the microbiota, individuals engaging in physical activities in greenspaces may face physical risks, such as injuries from falls, slips, or accidents.

Environmental Hazards: In some cases, greenspaces may be located near areas with environmental hazards, such as pollution or contaminated water sources. Exposure to these hazards can pose health risks.

Social Risks: While generally positive, the social aspect of greenspace exposure can also have downsides. For example, individuals may experience social anxiety or discomfort in crowded greenspaces.
