Thailand is pivoting toward a "wellness economy" as a response to rapid aging (projected to reach 28% population aged 60+ by 2576) and low birth rates (140,000 net population loss last year). The wellness sector—spanning physical, mental, and spiritual health—generated 419 billion baht in 2566 (up from 194 billion in 2565), driven partly by wellness tourism. This shift reframes aging from a crisis to an economic engine; the core challenge is extending "health span" (years of healthy life) to match life expectancy (currently a 10-year gap of suffering before death).
