Ireland have reported a clean bill of health ahead of Saturday's World Cup clash against Tonga in Nantes.
All 23 of the match-day squad came through the captain's run at a scorching Stade de la Beaujoire, where the temperature was approaching 30C.
The Pool B game kicks off at 8pm Irish time on Saturday.
"Yep, everyone came through," said defence coach Simon Easterby as World Rugby confirmed that once again, water breaks would be used this weekend.
"The heat is still something we have to be aware of. It's not going to be something that's going to be an issue tomorrow night hopefully in terms of the kick-off time.
"But we tend to not always use the whole period of the captain's run just depending on how the players are feeling and what we need to get through, so no reason for that [delay at start of the captain's run]."
Asked to compare the heat today to last week's match against Romania in Bordeaux, which was played in 35C, tighthead prop Tadhg Furlong joked: "I was thinking of putting a jumper on today compared to what we've been used to.
"Although it is hot, it doesn’t feel as hot, like an oven, or someone blowing a hairdryer in your face for the last few weeks."
Head coach Andy Farrell on Thursday announced a very strong Ireland side to take on Tonga, who are playing their first match of the competition.
While some expected the head coach to mix and match, he said he made his selection out of respect for Tonga, the tournament and his own team.
Leinster forward Furlong replied to a question on the selection.
"Bossman, I don't pick the team," he said.
"I think everyone is just delighted to get another opportunity, it’s a privilege to play, of course we respect Tonga and the players.
"You think of where they’re coming in from, it’s their first game of the World Cup, the players play all over the world and it must be special for them to get a bunch of them in a room to gel and bond for a prolonged pre-season, we are quite lucky we get to do it the majority of time in Ireland.
"It’s a special tournament for them, to spend it with their countrymen for a long time. Of course we respect them."
