The study gives you the real reason for being Gosbump


  • A new study suggests that fartbump is part of a larger system that not only keeps us warm, but also helps to heal hair.
  • The sympathetic nervous system reacts to cold air with goose skin. If it lasts for a long time, it commands new hair growth.
  • The authors note that other, currently unknown, relationships exist between this system and other parts of the body.

Everyone gets gossamped, but have you ever wondered why? Until now, the dominant hypothesis was that by elevating the hair follicles on the skin, fart bumps helped keep the body warm by providing more space for warm air to collect near the body. However, many scientists have noted this explanation, as the lack of body hair on modern humans leaves us with the ability of goose skin, but without the potential for its benefits.

Apparently, it makes very little sense, if it were really useless that we would expect more than a few people not to have the ability to get them that far.

A new study published in Cell This response suggests a different reason. Its authors argue that the same cells that cause goosebumps may be responsible for helping hair growth for the first time, giving growth reason to maintain this familiar phenomenon.

A study of hair growth

In animals, many organs are made up of three types of tissue: epithelium, mesenchyme, and nerve. In the skin, which is an organ, a nerve connects to the muscle in the mesenchyme. This nerve is part of the sympathetic nervous system and helps maintain homeostasis. The muscle itself is associated with stem cells in the epithelium that heal wounds and regenerate hair follicles.

Researchers focused on mice, as is typical of these studies, but suggest that the findings also apply to humans given the similarity between our skin and hair cells.

The researchers investigated the behavior and structure of the nerve under an electron microscope. To their surprise, the nerve was not only attached to the previously mentioned muscle tissue, but also wrapped around hair follicle stem cells.

Under normal circumstances, the sympathetic nervous system is always functioning at a low level. This keeps the body functioning normally. When researchers observed this behavior, they observed the signals sent to the stem cells by the nervous system in the hair follicles. These signals appear to keep stem cells ready for potential use.

However, when researchers exposed the tissues to cold, the activity intensified. A flood of neurotransmitters was released, and stem cells were activated. This led to the development of new hair.

Another experiment described how the nerve reached the stem cells in the first place. Co-author Yulia Schwartz concluded in a press release:

“We found out that the signal comes from the developing hair follicle. It secretes a protein that regulates the formation of smooth muscle, which then attracts the sympathetic nerve. Then in the adult, interactions with the nerve and muscle surround the four. Turns around. Regulating hair follicle stem cells to revive the new follicle follicle. It is closing the whole circle – the developing hair follicle is establishing its own niche. ”

Putting this together, it appears that fart bumps are part of a two-step response to cold. In the first, the muscle under the skin is stimulated to form a goosebumps. If this stimulus lasts long enough, the second stage is sympathetic, the sympathetic nervous system is formed in response to cold to develop new hair and repair for old.

This is interesting and all, but what possible application could this information contain?

In their press release, the authors suggest that further research may focus on how the body repairs itself in response to environmental stimuli under various conditions. The findings also state that there currently exist other unsafe relationships between the sympathetic nervous system and other parts of the body. These potential interactions will undoubtedly be discovered and investigated.

Everyone gets goosebumps now and then. We have always assumed that we knew why we still got them, even though there were some holes in the hypothesis. The findings of this study suggest that the benefits of taking farther bumps are more complex than initially thought. It just goes to remind us that we still have to learn about the most mundane things.
