Summary
The hygiene hypothesis suggests microbial exposure aids immunity, but modern hygiene practices over-clean environments. This article advocates for targeted hygiene to balance microbiome health and immune development.
Area of Science:
- Immunology
- Microbiology
- Public Health
Background:
- The concept of hygiene is linked to health and cleanliness.
- The hygiene hypothesis posits that reduced microbial exposure in early life impairs immune system development, increasing allergy risks.
- Current trends favor excessive environmental disinfection, potentially neglecting the benefits of microbial exposure.
Purpose of the Study:
- To re-emphasize the immunological importance of the hygiene hypothesis.
- To propose a shift from universal hygiene practices to individualized or targeted hygiene approaches.
- To discuss practical hygiene measures that support a balanced microbiome.
Main Methods:
- This is an opinion article, synthesizing current research on hygiene and the microbiome.
- It reviews the evolution of hygiene concepts and their impact on immunity.
- It discusses the implications of microbiome research for public health strategies.
Main Results:
- Modern hygiene practices may inadvertently disrupt the human microbiome.
- A balanced microbiome is crucial for proper immune system development and function.
- Over-sanitization can lead to an increased prevalence of allergic and autoimmune conditions.
Conclusions:
- Revisiting the hygiene hypothesis is critical for understanding immune-related disorders.
- Targeted hygiene strategies, rather than broad disinfection, are recommended.
- Maintaining a healthy microbiome through appropriate hygiene practices is essential for overall health.

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:26Defense Mechanism Against Infection

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
