#Hotworkouts

In glossy studios across Bangkok and beyond, the hottest trend isn’t just the music or the mirrors—it’s the temperature. Hot workout classes, from heated yoga to high-intensity interval sessions in warm rooms, have surged in popularity as gym chains tout benefits from increased calorie burn to better flexibility. But the latest research reveals a more nuanced picture: heat can alter how hard the body works, improve heat tolerance with regular exposure, and sometimes blunt the gains you’d expect from exercise in cooler air. For Thai readers, where outdoor heat and monsoon humidity already test the body, these findings matter for everyday fitness, public health messaging, and the design of exercise spaces in our own communities.
