Final answer:
You do not constantly feel your clothing due to a biological process called habituation, where your sensory receptors send fewer signals to the brain about the stimulus of the clothing after repeated exposure.
Step-by-step explanation:
You do not constantly feel your clothing on your body because of a phenomenon known as habituation. This is a biological process where your nervous system becomes less responsive to a stimulus after repeated exposure to it. When you first put on clothes, you may feel them because it's a new stimulus. However, as time goes on, your sensory receptors send fewer signals to the brain about the stimulus, leading to a decreased awareness of your clothing. This happens because your brain has deemed the information non-threatening and non-essential, allowing you to focus on other, potentially more important stimuli. Air convection and the role of clothing in maintaining thermal comfort only indirectly relate to this sensory adaptation. Your clothing helps to moderate the amount of heat that is lost to air convection, contributing to a sense of physical equilibrium or comfort.
