Goosebumps or spikes is a natural body’s response. However, few people know that this is actually a special mechanism to help people keep warm and react to emotions.
Humans get goosebumps every day
Walking out from the bathroom in winter, or suddenly having a cold wind blowing in the summer, many people feel goosebumps. Not only that, when people hear emotional songs or recall old memories, people can also get goosebumps. In short, humans get goosebumps every day for a variety of reasons and under many different circumstances.
From primitive times, the reaction to bumps will make the coat thicker, better keep the body warm. But with modern humans, when the coat has evolved to become more sparse, what effect does this reaction have?
Mechanism of goosebumps
Puffiness or goosebumps is a natural body’s response. This reaction usually occurs when the body encounters cold or strong emotions such as fear, anger, surprise, excitement …
At that time, the skin will emerge small round nodules, due to the constriction of the root skin. These nodules come from muscle contractions attached to each hair. The hair is deeply embedded in the skin and the hairline is located in the hair follicle. Each muscle attached to the hair follicle will cause the follicle to swell, put the skin layer up into tiny beads on the surface of the skin and erect hair, creating a goosebumps phenomenon.
This phenomenon is most often seen in the arms, legs, neck, … Especially appearing on the face for some people. They will go away on their own when the stimulus disappears.
In animals with long fur, this phenomenon creates a buffer, prevents heat loss and regulates body temperature. The thicker the coat, the more heat will be retained. But for modern people, this reaction is almost useless. Currently, apart from humans, animals such as cats, porcupines, … also have a similar phenomenon.
Emotions are factors that cause goosebumps in the body
Humans are more special than other animals when reacting to goosebumps not only caused by external conditions. Sometimes people are influenced by emotions.
When people listen to music or are touched by flashbacks of the past, the subconscious mind releases a hormone called adrenaline. After the hormone is secreted, it is released into the bloodstream and plays the role of transmitting nerve impulses to various organs. Adrenaline acts directly on the sympathetic nerves, helping the body to respond to threats. As a result, the body will get goosebumps when it arises with certain strong emotions.
