THE Covid-19-delayed Tokyo Olympics will take place in the heat and humidity of the Japanese summer this year, in temperatures likely to reach more than 41°C.

The Equine Veterinary Journal (EVJ) has put together a Special Collection of previously published articles covering the health and welfare of horses competing in hot and humid conditions. These articles are free to access and it is hoped they will help involved vets keep equine athletes safe in the extreme heat that is expected in Tokyo this summer.
