Sleep Apnea Syndrome (SAS), which causes severe daytime sleepiness and serious illnesses, is often preceded by a biased image of being a "disease for overweight people," leading many potential sufferers to overlook their own risks. To address this, the Japan Snoring and Sleep Apnea Association conducted an "Image and Knowledge Survey on Sleep Apnea Syndrome (SAS)" targeting 200 general men and women nationwide. The results highlighted an extremely strong image of SAS being common in "overweight people" and "those who snore loudly," while simultaneously revealing a misunderstanding that it is less likely to occur in "thin individuals" or "children," who are actually at risk. By visualizing the gap between the public's perception and the reality of those affected, this survey aims to sound an alarm against the unconscious oversight of "it doesn't concern me or my family" and offer insights for correctly addressing it as a common illness that anyone can develop. Survey Background Sleep Apnea Syndrome (SAS) is a condition where breathing repeatedly stops or becomes shallow during sleep. Generally, a strong image persists that it affects "overweight middle-aged men" or is "just a problem of loud snoring." However, in reality, it is a condition that can occur in anyone, regardless of body type, age, or gender, including "thin individuals" with small jaws, "women," "children," and "the elderly." Due to insufficient recognition of this fact, many cases are diagnosed and treated late because individuals postpone seeking medical attention, thinking, "I'm not overweight." This survey was conducted to visualize the reality of such misconceptions, improve health literacy through correct knowledge, and raise awareness of nearby risks. Survey Summary 72.0% know that "Sleep Apnea Syndrome" is related to snoring and breathing cessation. "Overweight people/obese people" are most frequently associated with being prone to SAS at 27.6%, followed by "people who snore loudly" at 20.6%. "T
