The Science of Cleansing: How Our Ancestors Practiced Hygiene vs. Today

Explore more about SCIENCE

Hygiene has come a long way from ancient oils and herbal remedies to today’s science-backed formulations. While history provides insight into natural cleansing, modern intimate care is rooted in dermatology, pH science, and microbiome protection.

Introduction

Cleansing has evolved drastically throughout history, shaped by cultural beliefs, scientific discoveries, and advancements in skincare technology. While ancient civilizations relied on natural ingredients and rituals, modern hygiene is driven by microbiome science, dermatology, and pH-balancing cleansers.

In this article, we explore how cleansing practices have changed over time, the science behind effective hygiene, and why modern intimate care products are better suited to preserving skin health.

Ancient Hygiene Practices: Natural Yet Imperfect

1. Egyptian Hygiene (3000 BCE - 300 BCE)

• Egyptians were one of the first cultures to develop soap-like substances made from animal fats and alkaline salts.
• They used honey, clay, and milk for skincare, which had mild antimicrobial benefits.
• Fragrances, like myrrh and frankincense, were applied to mask odors rather than eliminate bacteria.

2. Roman & Greek Bathing Culture (100 BCE - 500 CE)

• Public baths were central to daily life, where people used olive oil and strigils (scrapers) to remove dirt.
• Water was unfiltered, and communal bathing often led to skin infections and parasites.
• Wine vinegar and sulfur were occasionally used as antiseptics.

3. Medieval Europe (500 - 1500 CE): The Decline of Hygiene

• Bathing was considered dangerous due to religious beliefs and fear of disease spread.
• People relied on herbs (like lavender and rosemary) to mask body odor.
• Clothing was often perfumed, but actual cleansing was rare.

4. Asian & Middle Eastern Practices

• In China and Japan, bathing in hot springs and herbal water was common.
• In Islamic cultures, ritual washing (Wudu and Ghusl) emphasized cleanliness as part of religious practice.
• Rice water and green tea were used for gentle cleansing, particularly on delicate skin.

The Science Behind Modern Cleansing

1. The Role of the Microbiome in Skin Health

• The skin hosts trillions of beneficial bacteria that form a natural defense against infections.
• Overwashing with harsh soaps can strip away good bacteria, disrupting the skin's natural microbiome balance.
• Using pH-balanced cleansers (3.5 - 5.5) preserves the microbiome and prevents irritation.

2. Why pH Matters in Cleansing

• Traditional soaps often have a pH of 9-10, which is too alkaline and damages the skin barrier.
• Modern intimate washes, like Undecimber’s formulation, maintain a pH of 4.5, which aligns with the skin’s natural acidity. (Source: British Journal of Dermatology)
