In a healthcare setting, the importance of hospital cleanliness cannot be overstated. Research has shown that healthcare-associated infections can be significantly reduced by improving cleaning and hygiene practices among healthcare personnel. Maintaining a clean environment not only lowers the risk of infections but also saves lives. However, the extent to which cleanliness impacts overall health is not definitively clear. While some argue that exposing the immune system to challenges can be beneficial, the balance between cleanliness and immune system stimulation remains a topic of debate in the healthcare industry.
