It seems like a no - brainer that citizenry can find the rain during a storm or brine the second they jump into the ocean . But can our body actually " sense " the water on our hide ?
It turns out , the answer is no — at least not technically because our bodies do n’t have sensors specifically for find liquids . Rather , we swear on a conglomeration of other sensor to inform us when we ’re pie-eyed .
You can see water and feel its texture and temperature, but can you actually sense its wetness?
In thehuman body , a connection of neurons know as the somatosensory system helps us work on the things we touch . These specialized neurons , which let in mechanoreceptors and thermoreceptor , are responsible for relaying tactile information from the cutis to the brain , allow us to recognise objects by feel them and enabling us to discover different textures or temperature .
However , world lack hygroreceptors , which enable other animals , such as cockroach and honeybees , to detect water or changes in the moisture and humidness of an environment . Instead , " we develop a guess about whether or not water system is present on the surface in query , based off of the accumulation of uncommitted evidence , which is like this complicated , multidimensional thing,“Jonathan Samir Matthis , an adjunct prof of human motion neuroscience at Northeastern University in Boston , separate Live Science .

You can see water and feel its texture and temperature, but can you actually sense its wetness?
To identify liquid , humans tap into ocular stimuli and tactile sensations . For example , you see the smooth catamenia of water rushing over your hands in the sink and experience the sense datum of droplets hitting your face during a rain shower . But the most of import cue that humans apply to sense water through the cutis is temperature , agree to awide body of inquiry .
" If you ’ve got some wet on the skin , chances are that it ’s going to evaporate from the skin and it ’s going to cool down you , " saidDavide Filingeri , an environmental and sensory physiologist at the University of Southampton in the U.K. , who has open up much of the research on how human race march wetness . As a result , human might have been stipulate to associate the sensation of coolness with the mien of wetness , he say .
This may explain why it ’s hard to severalize when laundry on the occupation outdoors is dry if it is also cold , or why seat on a cold metal chair can sometimes sense like sitting in a pool . In a2013 study , Filingeri put this confusing sensation to the psychometric test . The research squad blindfolded nine individuals and pass through a series of tryout in which they pressed a ironical probe of alter dusty temperature to each participant ’s forearm . Five out of the nine player perceive that the juiceless input were sozzled if they were around 32 degrees Fahrenheit ( 0 level Celsius ) , which confirm that they were relying on just temperature to suss out whether something was moist .
" The brain does n’t have anything to distinguish between the illusion of wetness versus the existent wetness , " he told Live Science .
In 2014 , Filingeriran fundamentally the polar experiment , in which he prove the result of warm , loaded stimuli in a grouping of blindfolded participants . He found that none of the person were able to comprehend wetness during any of the simulations higher than 7.2 F ( 4 C ) above their cutis temperature .

Informed by these findings , Filingeri is currently working with clothing room decorator to create sportswear that is more breathable and can considerably handle lather . to boot , his lab is working with the Swiss Federal Institute of Technology Lausanne ( EPFL ) torestore thermal sensationsin amputees with prosthetics so that they can pull a fast one on the brain into " feel " wetness in missing limbs .
" There ’s a heap of interesting clinical and nonclinical applications for some of this work , " Filingeri said .
