Yes, exercise in thermoneutral conditions may produce some adaptations relevant to exercising in heat—but a 2026 meta-analysis found larger changes in several measured outcomes when exercise took place in hot conditions. The findings concern physiological responses and aerobic performance, not proof that exercise prevents heat illness or a reason to train in extreme heat.
What the 2026 meta-analysis found
Yonghui Chen and colleagues compared exercise in hot conditions (ExH) with exercise in thermoneutral conditions (ExN) in a meta-analysis published online August 24, 2026, in the Journal of Sport and Health Science. The authors searched five databases through November 20, 2025, and included 23 studies. They assessed core temperature, heart rate, skin temperature, sweat rate and aerobic performance in heat. The journal abstract reports standardized effect sizes for the comparison; these indicate relative differences across studies, not a guaranteed change for an individual.

| Measured outcome | ExH compared with ExN |
|---|---|
| Resting core temperature | Greater reduction with ExH (g = 0.51) |
| Core temperature during exercise | Greater reduction with ExH (g = 0.55) |
| Heart rate during exercise | Greater reduction with ExH (g = 0.69) |
| Sweat rate | Greater increase with ExH (g = 0.56) |
| Aerobic performance in heat | Greater increase with ExH (g = 0.56) |
| Skin temperature during exercise | No significant additional effect reported |
These results suggest that environmental heat added an adaptive stimulus for several outcomes measured in the included studies. They do not show that hot exercise is necessary to improve every response, or that the change will be the same for every person. Read the journal article and abstract.
Exercise in cooler conditions also changed some responses
Compared with participants’ baseline measurements, the ExN groups had significant improvements in exercise core temperature (g = 0.41) and exercise heart rate (g = 0.57), according to the abstract. The review therefore supports a limited but useful distinction: exercise without added heat was associated with improvement in some measured responses, while ExH produced greater changes across several of the outcomes compared directly.

How to interpret the numbers
The journal abstract presents standardized effect sizes, which describe the magnitude of a difference in a common statistical scale. They are not degrees Celsius, beats per minute or a prediction of a person’s response. Earth.com’s October 2, 2026, account of the paper reports absolute differences from the analysis: a 6.11 beats-per-minute heart-rate change favoring ExH, and additional reductions of about 0.17°C in resting core temperature and 0.09°C in exercise core temperature. The same report gives ExN-group reductions of about 5.6 beats per minute in exercise heart rate and 0.14°C in exercise core temperature. Those absolute figures are reported by Earth.com; the accessible journal abstract provides standardized effects instead.
Earth.com reports 413 participants across the studies, exercise interventions lasting four to 15 days, and hot-training temperatures from 30°C to 45°C, with an average of about 37°C. These are descriptions of the studies included in the review, not a recommended training range or an individualized program. Read Earth.com’s account.

Who the findings may—and may not—apply to
The evidence base is limited and varied. The source article describes overall certainty as low to very low, with differences in study protocols and testing methods. Participants were mostly men and often trained athletes; cycling was common. Some core-temperature results were unstable. The abstract also reports that additional benefits were more pronounced among elite athletes (Tier 3) and with longer interventions, but these subgroup patterns should not be treated as universal rules, particularly because some came from few studies.

Adaptation is not proof of protection from heat illness
The studies assessed physiological responses and aerobic performance. They did not establish whether exercise alone—or heat training—prevents heat stroke or other heat-related illnesses. Changes in core temperature, heart rate or sweat rate are measured adaptation markers; they are not evidence that a person is protected from dangerous heat. The results should not be read as encouragement to exercise in extreme heat.
