Tickle the armpit

Some people have ticklish spots almost all over their body. When others joke with them, as long as their neck, arms, legs and waist are touched, they will feel itchy all over. Especially when their armpits are tickled, the itchy feeling is more obvious. Itch is a kind of stress response of the human body. Generally speaking, the places where itching can be felt are located at nerve endings. These places will regard external contact as a threat, so people will feel itchy.

1. Reasons for armpit itch

Most of us get nervous when someone tickles us. Because you feel uncomfortable with this kind of physical contact, you have no control over it, and you worry about being tickled or hurt. Genetically speaking, "itching" is a nervous tension phenomenon in response to hostile behavior. That is, it is more obvious when encountering unexpected touch, especially in areas with shallow fat layers and well-developed nerves.

2. Why doesn’t it itch when you scratch your armpits?

Tickle yourself, everything is under your control. You don't need to be nervous and naturally you won't react. That is to say, because you are aware of your actions in advance, your brain has already notified the nerves to "lift the alarm", so naturally you won't feel itchy.

3. Why do people have itchy skin?

The itchy spots were also formed during a long evolutionary process. In order to survive tenaciously in a complex environment, humans have evolved a very sensitive nervous system to warn of danger. The brain will instinctively regard sudden unknown physical contact as a dangerous signal. Therefore, the itchy spots are actually nerve endings densely distributed in the superficial layer of the skin that produce an itch-induced response to external stimuli. The itchy spots are mostly found on the neck, armpits, waist, groin, inner thighs, soles of the feet, etc. According to the biological nerve distribution of the human body, these areas are also the main areas of lymph and nerve distribution in the human body. These nerves are directly connected to the brain nerves, and are therefore particularly sensitive to external stimuli.

4. What to do if there are too many itchy spots on the body

People have different physical constitutions and different sensitivity levels. There is no good way to alleviate them, and you need to pay attention to proper psychological restraint. The itchy skin is actually nerve endings densely distributed in the superficial layer of the skin that produce itching reactions to external stimuli. Some may be allergies. It is recommended to take some loratadine, or go to a dermatologist. Eat a light diet and eat less spicy and irritating food. Pay attention to changing underwear frequently, wear loose cotton underwear, eat less spicy and irritating food, eat more fresh vegetables and fruits, drink plenty of water, exercise more, and improve the body's immunity.
