As life in lockdown continues, Canadians have had to get creative with their workout regime and for many, it meant heading outside.
However, as the coldest months of the year are now underway, it s important to know the potential risks involved in taking your workout outdoors during winter.
“Through my research, the threshold of -15 C is something individuals and habitually active Canadians should pay attention to,” says Michael Kennedy, Associate Professor at the University of Alberta who specializes in Kinesiology and Recreation.
The reason for this is respiratory distress. Kennedy and his team conducted a study that tested athletes running on a treadmill in the following temperatures: 0, -5, -10, -15 and -20 C (40 per cent humidity).
2020 is on track to be Earth’s warmest year on record

jeudi, 23 avril 2020 à 13:15 - Despite the widespread drop in greenhouse gas emissions during the COVID-19 pandemic, NOAA reports that global temperatures will be record-breaking in 2020.
While the COVID-19 lockdowns have caused dramatic declines in greenhouse gas emissions, abnormally warm global temperatures are telling us that the climate is still heading into unprecedented territory.
The National Oceanic and Atmospheric Administration (NOAA) has reported that there is a 75 per cent chance 2020 will be the warmest year on Earth since record-keeping began in 1880. Global temperatures are expected to be warmer than those in 2016, which was declared the warmest year on record at the time. The unusually strong El Niño event of 2015-2016 contributed to 2016’s record-breaking warmth. There are currently no indications that we will see an El Niño event this year, however, which makes NOAA’s projection
Life-threatening extreme heat set to trap millions indoors by 2060 Reuters
lundi, 11 mai 2020 à 16:05 - Punishing heat is expected to last up to six hours a day by 2060, according to a new study.
Extreme heat and humidity are increasing across the globe, threatening millions of lives and economies in places where it could become fatal to work outdoors, scientists said on Friday.
Parts of Australia, India, Bangladesh, the Persian Gulf, China, Mexico and the United States have experienced hundreds of previously rare incidents of extreme heat and humidity since 1979, said the study in the journal Science Advances.
These punishing conditions have lasted only one to two hours but climate change is likely to prolong them to about six hours at a time by 2060 and expand the affected areas, lead author Colin Raymond told the Thomson Reuters Foundation.
