ASMR refers to a tingling sensation that some people experience in response to certain auditory, visual, or tactile stimuli, such as whispering, tapping, or crinkling sounds. The sensation is usually felt in the head, neck, or down the spine, and can be described as pleasant and relaxing. While the scientific community is still studying ASMR, research suggests that it may have a range of benefits, including reducing stress and anxiety, promoting sleep, and improving mood.
