The tongue, lips, and fingertips are the most
The forehead and fingertips are the most sensitive parts to pain, according to the first map created by scientists of how the ability to feel pain varies across the human body.
Why do you think one area is more sensitive than another? The part of your brain that receives information from your sensory neurons doesn't treat all parts of the body equally. The reason you are more sensitive on your fingertips than your elbow is that there are many more sensory neurons on your fingertips.
Areas including the fingertips, lips, and tongue have very high resolution, and therefore are the most sensitive. Other areas like the forearms, calves, and back are the least sensitive. This is illustrated as the distance where the two points can be felt as separate.
The glabrous skin of the hand and the forehead were the areas of highest spatial acuity, for both pain and touch.
The face has demonstrated to be the most common site of skin sensitivity (Table 3), predictable physiologically due to the larger and multiple number of products used on the face (particularly in women), a thinner barrier in facial skin, and a greater density of nerve endings (18).
The face, especially near the mouth, is exquisitely sensitive, the extremities, by comparison, poor, other regions, intermediate. (2) All body regions are more sensitive to cold than to warm.
People with allodynia are extremely sensitive to touch. Activities that aren't usually painful (like combing one's hair) can cause severe pain. Many conditions and injuries cause allodynia. To relieve pain, providers treat the condition that's causing it.
The forehead and palm were the most sensitive to touch, with median detection levels of 0.07 g, corresponding to the lowest monofilament in the range tested (Figure
The foot, lower leg and upper chest are much less sensitive than average; in comparison, the cheek, neck back, and seat area are 2–3 times as sensitive to both cooling and warming stimuli.
Skin pain or tenderness upon touch can have various causes such as sunburn, dermatitis, infection, nerve damage, or autoimmune disorders. It's best to consult a doctor for proper diagnosis and treatment.
Less sensitive areas, such as your back, can have as few as 10 pressure receptors in one cubic centimeter. Because of this, areas such as your back are much less responsive to touch and can gather less information about what is touching it than your fingertips can.
Your Sensitive Side
For example, recent research shows that one side of your body may experience pain differently than the other side. A study published in the December 2009 issue of Neuroscience Letters showed that right-handed study participants could tolerate more pain in their right hands than in their left hands.
Maybe a little ignored, lower back is the one of the most erogenous zone in a female body. Talking about men, they love all your curves woman! Saksham Mathur candidly admits,"The way her round bottom excite me, nothing else does. Moreover, just a little massage or caressing sets the passion right.
Sensitivity can vary quite a bit from woman to woman, with smaller breasts on average being more sensitive than larger breasts.
Your lips have more than a million different nerve endings, making them one of the most sensitive parts of your body (and 100 times more sensitive than your fingertips). They're even more sensitive because there's no defensive membrane to protect them.
A region's sensitivity depends on the number of receptors per unit area and the distance between them. Unlike the very sensitive lips and hands, receptors on your back are few and far apart so it's much less sensitive.
The back of the neck is a particularly sensitive spot due to the thinness of the skin and concentration of sensory receptors in the area.
Your fingertip
The ends of your fingers are more sensitive to pain than almost any other part of the body, according to an Annals of Neurology study.
Individuals who experience touch sensitivity often say they are more bothered by things that touch their skin than others. Sensitivity may occur with food textures, clothing or fabric textures, self-care tasks, and receiving a hug or kiss. Or, it could be with specific items like paper, pencil or messy play.
Thermal thresholds
There is a 100-fold variation in sensitivity to changes in skin temperature across the body, with the cheeks and the lips being the most sensitive area, and the feet being the least sensitive region.
Thermoreceptors are found all over the body, but cold receptors are found in greater density than heat receptors. The highest concentration of thermoreceptors can be found in the face and ears (hence why your nose and ears always get colder faster than the rest of your body on a chilly winter day).
What is the warmest part of your skin? The warmest parts of the human body are the head, chest and armpits. Conversely, the coldest parts are the feet and toes, which are farthest from the warm-blood-pumping heart.
Sensitive skin can happen anywhere on the body but is generally more pronounced on delicate areas like the face, armpits, elbows or groin. Unfortunately, the face is the most exposed area and often receives the brunt of the symptoms. Dry skin is often linked to sensitive skin.
