One of the worst tortures is to deprive people of the possibility of drawing information from their sense of touch. Loneliness is also hard, not only because we have no one to talk to, but most importantly, it is very important that we have no one to cuddle with. A hug significantly reduces stress levels and strengthens the immune system. ¹⁾

Meissner's corpuscles are responsible for sensations such as touching and shaking. They are most abundant on the fingertips, feet, lips, tongue, and reproductive organs, i.e. place particularly sensitive to touch. They are fast-adapting receptors, which means that we quickly get used to stimuli received through them. This is one of the reasons why the clothes we wear do not bother us. ²⁾

Pacinian corpuscles are receptors of pressure and vibration and are located mainly in the deep skin layers of the fingers, tendons, and joint capsules. They adapt quickly and react strongly only to new stimuli. Merkel's tactile meniscus - their function is to receive stimuli of constant pressure on the skin, therefore they adapt slowly. ³⁾

Ruffini's corpuscles are located in the deeper layers of the non-hairy skin and are responsible for stretching and are heat receptors. They perceive temperature higher than human body temperature and adapt slowly. ⁴⁾

Bulboid corpuscles are cold receptors. They are located mainly in the layers of the dermis and are slow to adapt. ⁵⁾

Free nerve endings - their primary function is to transmit information about pain, including that caused by excessive heat. Among the pain receptors (nociceptors) we distinguish mechanical receptors responsible for the sensation of sharp, stabbing, well-localized pain and polymodal receptors that produce an inaccurately localized sensation of poorly tolerated pain; pain receptors do not adapt. ⁶⁾
