A growing number of men in Japan have been battling a condition known as "hidden cold syndrome", marked by an unusual sensitivity to cold. This is attributable to a combination of lifestyle habits, diet, and other factors. The issue has grown to such an extent that preventive measures are now being widely promoted and discussed in various health-oriented platforms in Japan.

Health and wellness are regarded with high importance in Japan. The Japanese maintain a comprehensive diet, perform regular exercises, and generally lead highly regulated lifestyles. Therefore, the increasing prevalence of men suffering from the 'hidden cold syndrome' has raised significant concern within the society and is seeing considerable attention from both individuals and health institutions.

In the US and EU, men's health issues often focus more on problems like heart disease, obesity, and mental health. While the general concern for men's health is comparable, the specific issue of 'hidden cold syndrome' has not received as much attention outside Japan.
