England meets Norway in World Cup quarterfinal

England and Norway will face each other in a World Cup quarterfinal on Saturday in South Florida. The wet-bulb globe temperature at the venue is forecast around 88 degrees Fahrenheit. The American College of Sports Medicine recommends stopping athletic activity when the index exceeds 82 degrees Fahrenheit.

player safety FIFA requires cooling breaks after 30 and 75 minutes only when the temperature surpasses 90 degrees Fahrenheit. A researcher in environmental ergonomics and physiology at Loughborough University said players may reduce sprints or distance covered. He added that motivation can override bodily signals and increase the risk of heat exhaustion.

rule changes A coalition of scientists from five continents sent an open letter to FIFA in May stating that three-minute hydration breaks are too short. The group recommended postponing matches when the wet-bulb globe temperature reaches 82 degrees Fahrenheit or higher.

Scientists from the New Weather Institute stated that older supporters and those with pre-existing health conditions face particular risks of heat exhaustion, dehydration, and heat stroke. Miami has recorded rising temperatures in recent years from concrete and greenhouse gases.
