‘I was lucky I didn’t go into a coma’: Football’s fight against extreme heat and the climate crisis

Referee Janny Sikazwe did not have a good game when he oversaw the chaotic Africa Cup of Nations match between Tunisia and Mali.

The Zambian awarded a debatable penalty to each team and raised eyebrows with an extremely harsh red card against Mali’s El Bilal Toure. He then mistakenly blew for full-time – twice – before the 90 minutes were up and allowed no injury time when several minutes were expected.

The episode was treated with derision and branded “farcical” by some pundits, but the circumstances were far from funny.

Heatstroke can cause physical and mental exhaustion, reduced alertness, an increased heart rate, and even sudden cardiac death.

Sikazwe told Zambian media: "I was lucky I didn’t go into a coma. It would have been a very different story.

"The doctors told me my body was not cooling down. It would have been just a little time before [I would have gone] into a coma, and that would have been the end.

"I think God told me to end the match. He saved me."

Cameroon’s tropical conditions, which have seen some games played in temperatures over 30C and high humidity, have caused serious issues at the tournament.

Algerian players have also claimed Cameroon’s climate also influenced the outcome of their 0-0 draw against minnows Sierra Leone in their first match at the Africa Cup of Nations (Afcon).

Left-back Ramy Bensebaini described the match as "very complicated and very hot," while Sierra Leone defender Steven Caulker said the humidity in the Japoma Stadium was "crazy".
