The authors included 12 studies with 347 participants in their analysis.<\/p>\n<p>The researchers found that the highest T<sub>core<\/sub> was 38.9 degrees Celsius, which was reported during land-based exercise. No woman exceeded a T<sub>core<\/sub> of 39 degrees Celsius, which is considered maternal hyperthermia in pregnant women. The highest mean end-trial T<sub>core<\/sub> was 38.3 degrees Celsius for land-based exercise, 37.5 degrees Celsius for water immersion exercise, 36.9 degrees Celsius for hot water bathing, and 37.6 degrees Celsius for sauna exposure.<\/p>\n<p>&#8220;Pregnant women can safely engage in: (1) exercise for up to 35 minutes at 80 to 90 percent of their maximum heart rate in 25 degrees Celsius and 45 percent relative humidity (RH); (2) water immersion (\u226433.4 degrees Celsius) exercise for up to 45 minutes; and (3) sitting in hot baths (40 degrees Celsius) or hot\/dry saunas (70 degrees Celsius; 15 percent RH) for up to 20 minutes, irrespective of pregnancy stage, without reaching a core temperature exceeding the teratogenic threshold,&#8221; the authors write.<\/p>\n<p><a href=\"https:\/\/bjsm.bmj.com\/content\/early\/2018\/01\/24\/bjsports-2017-097914\" target=\"_new\">Abstract\/Full Text<\/a><\/p>\n<p><i><\/i><\/p>\n<p><i>Copyright \u00a9 2018 <a href=\"https:\/\/www.healthday.com\/\" target=\"_new\">HealthDay<\/a>.
