During Murrray’s first round win over James Duckworth, at the changeover between games, the British star used an ice towel to stay cool.
And should Murray’s match go into a fourth set, he can request a 10-minute break as per the ‘Extreme Heat’ policy implemented by US Open officials.
Temperatures in New York today are set to hit 36C/96F and in a bid to protect the players, officials are giving them a short break to recover.
A US Open statement said: “The Extreme Heat policy is in effect for women’s and men’s singles matches until further notice.
“For all women’s singles matches, a 10-minute break will be allowed between the second and third sets if either player requests such a break.

Murray has a 13-1 winning record against Verdasco but their last meeting was in Dubai in 2017.
And the 31-year-old says he can’t allow Verdasco to dictate their match.
Murray said: “Obviously, Fernando has an extremely heavy forehand, plays with a lot of spin.
“On the serve, kind of difficult sometimes to know what he’s going to do. I have played him sometimes where he’s been going for huge serves.
“And then I also played in one, he served he served like 80% first serve and kind of rolled the serve in.
“Fernando is a great shot-maker and someone that when he’s on his game, really tough to beat.
“Yeah, when he’s dictating, as well, you can’t allow him to dictate too much.”
