How many holes do humans have? Let's find the answer to the question of how many holes do humans have !
Have you ever pondered the complexity of the human body? Is it one solid entity, or is it more like an intricate network of openings and tunnels? In this exploration, we will delve into the question of how many holes the human body actually possesses, covering the spectrum from microscopic pores to anatomical orifices.
The notion that the human body is like a doughnut, simply a collection of tissues surrounding a central core, makes us question the validity of such a comparison. In addition to obvious openings like the mouth and anus, humans have a variety of other openings—nostrils, ears, nipples, and pores. These seemingly diverse openings raise an interesting question: What defines a hole in the human body?
To begin this investigation, we need to navigate the complex landscape of molecular dimensions. Imagine the ability of garlic molecules, when applied to the skin, to permeate and reach the mouth, highlighting the interconnectedness of the body’s various elements. However, as we explore the human body at a smaller scale, the concept of pores becomes more complex.
The distribution of hair on the human body depends on gender, age, and hair color. Brown-haired people have a higher density of hair follicles than red-haired people.

Based on anthropologist Adolf Schulz's research on hair follicles to differentiate humans from other primates, we can give an approximate answer to the number of hair follicles on the human body.
According to Adolf Schulz's research, on average, humans and primates have the same number of hair follicles, about 300 per square centimeter. The density of hair follicles on the chest is the smallest, only one follicle per square centimeter. Accordingly, if based only on the average density of hair follicles, there are 5,000,000 holes on the human body.
In fact, in addition to hair follicles, humans also have sweat glands. According to the results of a recent study, it is estimated that humans have a total of about 3,000,000 sweat glands.
Adding up the total number of holes in the human body is a terrifyingly large number compared to what any of us had anticipated.
