Temperatures this week are proving dangerous for players and fans, with a threatening heat dome covering central and eastern United States.

Heat index temperatures, which combine humidity and air temperature, are expected to rise above average. Concerns over extreme heat began months ago across the United States.

Cities and stadiums have increased access to shade, cooling areas, and water for spectators, as well as medical personnel stationed in fan zones, to prevent illness caused by extreme heat.

Fans are most at risk when exposed to heat for hours, such as during outdoor celebrations and travelling. It is advised that spectators drink plenty of fluids, cold drinks, stay out of the sun and limit any exercise.

Maggie Aldousany, clinical professor in Kinesiology and Sport Sciences at the University of Miami, said: “It’s really important to realize that it’s not enough to wait to get thirsty.”

She further added that, when possible, spectators should “limit alcohol consumption”.

The high temperatures lower game intensity, causing players to adapt by reducing sprinting and risks. Players have medical staff and cooling breaks to prevent them from suffering from exertional heat stroke.

"It's really important for both the spectators and the players to consider the heat as a factor when they consider hydrating before going to the game,” said Maggie Aldousany.

The National Weather Service issued an extreme heat warning for Kansas City, Boston, and New York City, with temperatures reaching as high as 43 degrees.

People taking certain medications as well as older people, are more likely to suffer from the increased high temperatures.
