Andy Murray speaking to BBC Sport's Piers Newbery
I don't know how many chances I'm going to have to win more Grand Slams and to blow one because I hadn't prepared properly would be a huge regret.
The last time I played my second-round opponent Robin Haase was at the US Open in New York last August, and it was one of my toughest matches as I suffered with terrible cramps.
I came through in four sets but could have gone out of the tournament, not necessarily through me being the worse player but because I missed something in my preparation and became very dehydrated.
You have a match like that and it's a bit of an eye-opener.
I had always eaten well and tried to drink the right things but this was about being more meticulous; actually getting the correct information and just sticking to it.
I take that side of things more seriously now, for sure. My diet is pretty well managed during events.
It would be hard to take if I went out of a Slam because I hadn't drunk enough beforehand, or hadn't checked the weather and the humidity so I knew how much I was supposed to be taking on board.
The margins are very small at this level and I train very hard - I wouldn't want to put in all the preparation and then blow it because of a small detail.
I'm sure good preparation played its part on Tuesday for my first-round match against Mikhail Kukushkin, because I haven't played too many matches on Centre Court when the temperature reached 41 degrees.
I spent just over two hours out there. My recovery might change a little bit depending on circumstances and how a match went.
I could spend more time with the physio after a longer match because in that situation you come off court and things actually hurt! You need that extra time.
I do an ice bath after every single match throughout the year, whether it has lasted one hour or four hours, because I just feel like it helps me.
After Tuesday's match I came off court and went on the bike, and was given water and a sports drink by my fitness coach Matt Little. I probably drank about a litre or so in the 30 to 40 minutes after I came off.
I then had a shower, drank a protein shake and ate some pasta and chicken. Then it was about 45 minutes with physio Shane Annun for a massage and a stretch, and then an ice bath.
Feeling the heat at SW19Normally during Wimbledon I would use my ice bath at home but they have them on site at the All England Club this year, so I did eight minutes at eight degrees Celsius.
- The hottest ever temperature at the tournament was 34.6C on 26 June, 1976.
- When Murray won his Wimbledon title in 2013, the conditions reached 30C.
- Wimbledon's 'heat rule' allows female players a 10-minute break between the second and third sets of matches played in extreme temperatures.
This is the first time I've been at a tournament with both my coaches, Amelie Mauresmo and Jonas Bjorkman, and that means the tennis side of my preparation is well covered.
The three of us sat down and chatted about what to expect in my first match after my practice session.
Normally I'll have some video sent to me and various statistics, which I'll look at myself, and when I watch the videos I'll message Amelie and Jonas and point out things I saw that are maybe different from what we spoke about.
During the week at Queen's Club , Jonas went out and watched a couple of the guys that I might be playing, but nowadays I do a lot of it on video and with statistical analysis.
Sometimes going out onto the court can help though because you can't always see exactly what's happening on the video.
It will be the fifth time I've played Haase on Thursday, so hopefully there won't be too many surprises.
As is so often the case, the weather was the number one topic of conversation at Wimbledon on Tuesday but for once it was not the prospect of rain that brought out the umbrellas but a beating sun on what was forecast to be the hottest day of the year.
Afternoon temperatures were expected to reach 30 degrees Celsius (86 Fahrenheit) -- considerably higher on court -- and the public address announcers were busy warning fans to drink water, apply sunscreen and wear hats.
While organisers of the Australian Open would consider such temperatures to be something of a spring chill, for Wimbledon it is truly tropical.
Almost all the outside courts offer no shade at all and even the show courts are exposed to the sun's full glare for most of the afternoon, with only the large umbrellas held by ball boys and girls during changeovers offering relief for the players.
There is a "heat rule" in place but it is about as clear as cricket's Duckworth-Lewis system divided by Pi squared.
Firstly, for no apparent logical reason, it applies only to the women. They are allowed a 10-minute break between the second and third sets when the "heat stress index" is at or above 30.1 degrees Celsius, but only if it reaches that figure before the match starts. The heat stress index is produced by factoring in air temperature, humidity and surface temperature.
Why it does not apply to the men's game, where best-of-five matches are often considerably longer, nobody at Wimbledon was immediately able to explain.
The retractable roof on Centre Court was installed to keep out the rain and there are no rules in place to allow it be closed to reduce the court temperature, despite that being regular practice at the Australian Open in Melbourne where 40 degrees days are not uncommon. Organisers will be pleased, however, with their decision to install an additional six ice baths in the locker rooms this year. Normally used for post-exercise recovery, players are being advised to have a pre-match dip ahead their matches.
With Wednesday's temperatures expected to be even higher, Britain's Met Office has issued a "Level Two Heat Alert" which helps healthcare services prepare to deal with a potential surge in cases of people suffering from heat-related issues.

A HEATWAVE is due to hit Wimbledon this week - but the players will be keeping cool after the All England Club installed ice baths for the first time.
The baths are used by many athletes as part of their post-match recovery. Andy Murray has one at his home.
Players at Wimbledon have previously had to go elsewhere to cool down or settle for make-shift solutions, but now they can enjoy - or endure - an ice bath in the comfort of the club.
The baths are among a raft of measures brought in to improve facilities for the players at SW19.
Others include a new warm-up, warm-down and stretching area and an expanded players' Iounge. The Aorangi Pavilion where the stars practice has been totally overhauled.
There is also a new café and deli for players and better online access.
Former Wimbledon champion Maria Sharapova, 28, told the Standard: "I think Wimbledon always with each year tries to improve the conditions and Iooks at things from a player's perspective which l think we all really appreciate."
"They've done a few nice things for us in terms of the locker rooms and the ice baths which is great for recovery and things like that."
Murray has spoken of the merits of ice baths, writing last year: "While it couldn't exactly be described as a relaxing bath, I don't mind doing it because I know how much it helps."

The heatwave enveloping London has us all dreaming of a refreshing dip in ice-cold water, but a proper ice bath – technically a ‘cryospa’, and not so much refreshing as a painfully numbing but ultimately invigorating experience – was always going to be a reality for the players at the 2015 Championships.
Wimbledon is the first Grand Slam to install ice bath facilities. Six tall, white, upright baths stand ready to receive hot and sore muscled limbs in the new improved competitors’ facilities (three for the ladies, three for the gentlemen) plus two further baths in the Aorangi practice area. Their introduction is proving popular. On Day 1, roughly a third of the competitors on site used the Millennium building facility, with the last player in at 10.10pm after a final game on a show court.
As they are post-exercise recovery aids, the ice baths stand quiet all morning. From 2pm until an hour after close of play, there is a steady stream of takers and a surprisingly social air in a room most us would regard as a torture chamber.
Forget all images of a standard home tub filled with ice cubes, like a makeshift drinks cooler at a student party. These cryospas are state-of-the-art machines which require players to climb up three steps then slide down into a standing tub of chilled water set at 8C, 10C and 12C so that players can pick their preferred degree of pain.
Neoprene socks are provided to prevent feet becoming too cold (which may be intolerably painful). Opposite each machine is a bench so that the player’s physio and fitness team can chat to them and help distract from the numbing discomfort. The Murray brothers are both known fans.
Your intrepid reporter has not only immersed an arm hot from the keyboard into the 8C bath and can vouch for the horribly bitter-sweet exhilaration the treatment induces in a limb, but also witnessed Andy happily standing in a post-practice ice bath and noted 10C was his preferred setting. The odd childhood swim in a Scottish loch would have been perfect preparation.
Post-game, an immersion of 6-10 minutes is considered optimum; post-training, 4-8 minutes is suggested. Some players prefer the ‘contrast’ method, alternating between the ice bath and a warm shower. In this case, the suggested protocol is a one-minute warm shower/two minutes icy water, through three to five rotations.
While spectators ponder the 'ice and slice' in their Pimm's, the phrase means something altogether different for players in their zone of perfect grass-court preparation.
It's game, set and match for a Co Down manufacturer whose ice baths are soothing the limbs of players from around the world at Wimbledon.
CET CryoSpas in Dromore, which was set up by Colin Edgar, shipped eight of its spas to the championship.
No doubt they'll be a welcome post-match retreat after soaring temperatures heralded the start of the annual lawn tennis pilgrimage to SW19, which yesterday saw defending champion Novak Djokovic sail through his first round match on Centre Court.
Day one also saw the first British player, Liam Brody, reach the second round following a five-set thriller in his opening match, ahead of hot-ticket Andy Murray, the 2013 champion who's set to start his challenge today.
Security was stepped up for the start of Wimbledon amid heightened fears of terrorism, following last week's Tunisian atrocity. The risks failed to dampen spirits of the 40,000 spectators though, with One Direction star Niall Horan from among the first celebrities to be spotted.
Meanwhile, tennis stars have been tweeting their appreciation of the Northern Irish ice baths. Serbian Davis Cup player Dusan Lajovic sent one message reading: "Great ice bath guys."
And veteran player and commentator Pam Shriver tweeted "one reason players careers are longer..." and attached a picture of the CyroSpa.
Other clubs and teams which have made use of the cold hydrotherapy treatment from the Co Down firm include footballing giants AC Milan and Manchester City, the English National Ballet, the German Olympic Sports Confederation and Team GB.
Mr Edgar said: "Incorporating ground-breaking engineering with advanced cold hydrotherapy treatment, the CET CryoSpa benefits athletes' performance by optimising post-exercise recovery strategies, lowering the risk of injury and post-match fatigue."
The All-England Lawn Tennis Club, which hosts Wimbledon, has spent £20m on refurbishing its player facilities, where the spas have been fitted in the company's biggest ever installation.
WHEN tennis stars like Andy Murray, Rafael Nadal and Serina Williams take a dip in a hydrotherapy pool at Wimbledon this week, chances are it'll have been made in Co Down.
Dromore based CET CryoSpas, which makes spas for targeted recovery among athletes from a range of sports, have installed eight spas at the All-England Lawn Tennis Club in its biggest contract to date.
Wimbledon, the world's longest-running and most prestigious tennis tournament attracting 500,000 spectators, has spent £20m on refurbishments this year, including adding a new medical, warm-up and recovery facility in Centre Court and a new players' lounge and recovery facility.
Players will now be able to enjoy the convenience of no less than eight CryoSpas, making the installation CET’s largest to date.
Well known clubs such as Manchester City and AC Milan, as well as the English National Ballet, the German Olympic Sports Confederation and Team GB, have all previously used the Dromore firm's facilities.
CET managing director Colin Edgar said: "Incorporating ground-breaking engineering with advanced cold hydrotherapy treatment, the CET CryoSpa benefits athletes performance by optimising post-exercise recovery strategies, lowering the risk of injury and minimising post-match fatigue.
"We're delighted to be part of the Wimbledon set-up this week and next."
