Secretly collecting sweat: A sneaky tactic to gather perspiration - Fascinating Facts About Sweating: A Comprehensive Overview (15 Points)
In the human body, there are two types of sweat glands: eccrine and apocrine. These glands play distinct roles in our body's temperature regulation and the development of body odour.
Eccrine glands, which make up about 80% of sweat glands, are distributed all over the skin, especially on the palms, soles, and forehead. These glands are smaller and located deep in the dermis, and they open directly onto the skin surface through pores. Eccrine glands primarily regulate body temperature by producing a clear, watery, hypotonic sweat, ideal for cooling the skin through evaporation. This process is controlled mainly by the nervous system and contributes minimally to body odour [1].
On the other hand, apocrine glands are found mainly in hair-covered areas such as the armpits, genital region, nipples, and ear canal. Apocrine glands are larger and located deeper in the dermis and sometimes hypodermis. They empty into hair follicles, and their secretions are thicker, containing proteins and lipids. Apocrine glands are activated by emotional stimuli and are involved in the pheromone response, contributing significantly to body odour due to bacterial decomposition of sweat components [2].
The key differences between these two types of glands lie in their location, size and depth, duct opening, secretion type, function, control, and the composition of sweat. While eccrine glands primarily serve thermoregulation purposes, apocrine glands are associated with body odour due to bacterial breakdown of organic compounds [3].
It's important to note that sweat itself is odourless; the pungent aroma comes from bacteria breaking down sweat components. This breakdown process is more pronounced in apocrine sweat due to its richer composition.
Interestingly, hyperhidrosis, a condition characterized by excessive sweating, affects around 1.5 million people in Germany. Botox and nerve stimulation treatments can help manage this condition by preventing the sweat signal transmission or stimulating nerve endings so they no longer transmit the sweat signal [4].
Furthermore, research has identified hormone-like substances in teenage sweat, which could explain the strong odour experienced by many parents during adolescence, a time when apocrine sweat glands fully develop, leading to drastic changes in body odour [5].
In conclusion, understanding the differences between eccrine and apocrine glands provides valuable insights into the complexities of the human body's temperature regulation and the development of body odour.

The Commission has also adopted a proposal for a Regulation on the establishment of a European Community for advancements in science related to health-and-wellness, which could include research on the role of fitness-and-exercise in regulating sweat production and the impact on skin-care. This proposed regulation may address the nutrition requirements needed for optimal sweat production and its effects on body odour. In light of the understanding of sweat glands and body odour, a potential cooperative initiative between the European Community and health-and-wellness industries could focus on developing new fitness-and-exercise routines, skincare products, and nutritional supplements designed to promote body temperature regulation, reduced body odour, and overall well-being.
