With summer heatwaves upon us, runners often debate whether to brave the warmth. Some love sunny jogs, others avoid them entirely. But does exercising in hot weather truly boost calorie burn? As fitness experts drawing from reliable sources, we've got the evidence-based answer.

The short answer? It depends. Key factors include your basal metabolic rate (BMR)—the calories your body burns at rest to sustain essential functions. BMR varies by activity level, genetics, and even climate, influencing overall energy expenditure.
Heat can slightly raise BMR as your body ramps up cooling efforts like sweating. However, no studies pinpoint exact extra calories burned. Adaptation plays a big role: beginners in hot conditions may torch more initially, but seasoned athletes burn fewer as their bodies adjust efficiently.
Post-workout satisfaction might feel amplified in the heat, but extreme temperatures often shorten sessions, limiting total burn and gains. For optimal results and safety, prioritize cooler hours or indoor options during peak heat.
