" Nature step" to prevent noncommunicable inflammatory disease

Area of Science:

• Immunology
• Environmental Health
• Epidemiology

Background:

• Disease prevention has advanced by addressing risk factors, yet the rise in allergies and type 1 diabetes remains unexplained.
• These conditions are linked to chronic low-grade inflammation and immune system dysregulation.
• Urban lifestyles and environmental shifts alter human microflora, impacting immune responses.

Purpose of the Study:

• To explore the unknown causes behind the increasing prevalence of allergy and type 1 diabetes.
• To discuss how environmental and lifestyle factors influence immune regulation.
• To propose the "nature step"—enhancing human-nature connection—as a health promotion strategy.

Main Methods:

• Review of current literature on immunology, environmental factors, and chronic diseases.
• Analysis of lifestyle and environmental changes in urbanized populations.
• Case study focusing on allergy as a model for immune dysregulation.

Main Results:

• Increased prevalence of allergy and type 1 diabetes correlates with altered human microflora and immune imbalance.
• Urbanization and lifestyle changes are implicated in disrupting immune regulation.
• The human-nature connection is identified as a potential factor in maintaining immune homeostasis.

Conclusions:

• The rise in allergic and autoimmune diseases may stem from a disconnect with nature, impacting immune system balance.
• Interventions promoting a "nature step" could support immune regulation and public health.
• Further research into environmental influences on the human microbiome and immune function is warranted.
