The midfielder is also hoping to have a key role in England's clash with Italy tomorrow evening.
Liverpool and England midfielder Jordan Henderson has said the Three Lions have just got to try and not think about the heat and humidity that will face them in their opening Group D clash against Italy in Manaus tomorrow, with temperatures forecast to be 33 degrees Celcius, and humidity of 60%.
Henderson is likely to line up alongside his captain for both club and country in Steven Gerrard in the heart of the England midfield as they look to get off to a good start against the four-time World Champions, and the 23-year-old believes the side have prepared well.
He told Radio 5 Live: "We have done adaptation training, either in chambers or warm weather training in Miami, Portugal and now in Brazil.
"Hopefully our bodies have adapted to it a little bit. You can see it is going to be hot but we have just to forget about that and concentrate on the game. I am sure we are fit enough for our bodies to deal with it."
Henderson has enjoyed an excellent season for Liverpool, appearing in all but three of their Premier League games as they finished two points behind Manchester City in the title race.
A player that is renowned for his energy and ability to cover a lot of ground in the game, he could be a key figure for England tomorrow night, as well for his ability on the ball as he has demonstrated good passing range.
Henderson added: "I feel I have improved over the course of the season and that is what I want to keep doing.
"I will keep working hard and listening to the right people.
"Hopefully I can continue doing that and doing my best for England."
Henderson has played both the warm-up games against Peru and Honduras when much of what is believed to be Roy Hodgson's best XI have played, so it would be a little surprising if he was omitted from the starting line-up tomorrow.
