Study challenges overheating risk for pregnant women exercising in heat Pregnant women are at no greater risk of dangerous ‘overheating’ when exercising in hot weather compared to non-pregnant women, according to a world-first Australian study.
The findings question recommendations discouraging exercise in hot weather due to the potential risk to the unborn child associated with ‘overheating’ or maternal hyperthermia, defined as a rise in core body temperature above 39°C or 102°F.
The research is led by the University of Sydney’s Thermal Ergonomics Laboratory and was recently published in Sports Medicine.
“This is the first study to show that pregnant women can safely engage in moderate-intensity exercise for up to 45 minutes at up to 32°C (90°F) and 45 percent relative humidity with minimal risk of overheating,” said senior author Professor Ollie Jay of the University of Sydney’s Faculty of Medicine and Health and Charles Perkins Centre.

Eskom continued with stage 2 load shedding on Tuesday 1 June 2021, with energy expert Ted Blom predicting stage 4 power cuts could be implemented by Wednesday.
In addition, the power utility warned generation supply constraints “will persist throughout the high winter demand period”. Of course, the cold weather is proving to be a challenge as well.
The South African Weather Service (SAWS) has forecast South Africa will also face a week of very cold temperatures thanks to the cold front moving over the eastern parts of the country, which is sustained by the development of a cut-off low-pressure system.
