As the temperature drops, or if we catch a chill, our body responds with goosebumps or shivering. This is due to the body\u2019s nerve receptors and how they react to the environment. Let\u2019s take a deeper look at how the body processes cold.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2>How the Body Processes Cold<\/h2>\n<p><span style=\"font-weight: 400;\">It is said that even a 1-degree change in air temperature is felt and can be healing in a sense. The skin is filled with temperature sensing nerve receptors. Receptors are a part of the nerve that receives a stimulus from the environment. Such stimuli may be pressure, tearing, cold, hot, or chemical, among others. To sense cold, the brain uses cold-receiving cell receptors. These have been named TRPs. For cold, the body typically uses TRPM8.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">TRPM8 is a calcium channel and is voltage-gated. As the temperature changes, the receptor releases calcium and changes the charge of the cell. That charge becomes an action potential and sends an electric signal to the brain. In the brain, that signal is interpreted as what we know as \u2018cold.\u2019 TRPM8 only fires within a certain range or temperature or if substances, such as menthol, eucalyptol, or icilin (AG-3-5), hit the receptor.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The cold receptors normally function at a \u2018steady-state.\u2019 That is, they maintain a certain level of electric discharge and the brain interprets this as the normal room temperature or skin temperature. When a cold stimulus is applied (an ice cube for example), the signal changes rapidly and that change is interpreted as cold. These are slowly conducting receptors that have a very dynamic response to temperature change.\u00a0<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2>The Range of Cold Sensation<\/h2>\n<p><span style=\"font-weight: 400;\">The body can sense between a general cooling that is pleasant (&lt;30C to 15C) and that which is painful and damaging (&lt;15C). Different receptors sense each of the possible different ranges of temperature.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There is a molecular foundation for thermoreception. We think there are about 28 different cation-permeable ion channels of the TRP group (transient receptor potential) which all respond to a very large range of stimuli.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">TRPM8 (transient receptor potential melastatin 8) responds to innocuous cold or cooling. This receptor sends a signal to the brain when the temperature changes only a little bit. There is also another receptor known as the cold\/menthol receptor 1 (CRM1). Other TRP receptors are engaged when the temperature becomes so cold as to be painful and noxious. <\/span><\/p>\n<p>&nbsp;<\/p>\n<h2>Your Source For Information<\/h2>\n<p><span style=\"font-weight: 400;\">The body is intricately wired to experience various sensations \u2013 the feeling of being cold is just one of many.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For more articles on health, wellness, and medical education, make sure to follow along with us at Warner Orthopedics and Wellness!<\/span><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: right;\">Meredith Warner, MD<\/p>\n<p style=\"text-align: right;\"><img decoding=\"async\" class=\"alignnone size-full wp-image-313666\" src=\"https:\/\/natalien12.sg-host.com\/wp-content\/uploads\/2020\/01\/WOW_Meredith_Signature_Navy.png\" alt=\"\" width=\"200\" height=\"164\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/natalien12.sg-host.com\/contact-us\/\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter wp-image-218596 size-full\" src=\"https:\/\/natalien12.sg-host.com\/wp-content\/uploads\/2018\/01\/web-button-for-blog-2.jpg\" alt=\"Orthopedic Surgeon Baton rouge appointment\" width=\"850\" height=\"286\" srcset=\"https:\/\/warnerorthopedics.com\/wp-content\/uploads\/2018\/01\/web-button-for-blog-2.jpg 850w, https:\/\/warnerorthopedics.com\/wp-content\/uploads\/2018\/01\/web-button-for-blog-2-600x202.jpg 600w, https:\/\/warnerorthopedics.com\/wp-content\/uploads\/2018\/01\/web-button-for-blog-2-300x101.jpg 300w, https:\/\/warnerorthopedics.com\/wp-content\/uploads\/2018\/01\/web-button-for-blog-2-768x258.jpg 768w\" sizes=\"(max-width: 850px) 100vw, 850px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dr. Warner here \u2013 \u00a0 Our bodies are programmed to notice changes in temperature.
