Well...it's been damned hot here in Melbourne and it's going to be again tomorrow. (40+) Thought I might bring it up for discussion, based on my own humble experience...which may or may not differ from others.. So how do you ride and survive in the heat?... Firstly and most importantly...everyone has their own threshold of discomfort and bodily ability to deal with it, and it can vary from one day to the next...so there is no foul in calling it a day early due to the heat (remember! - you have to still ride home), or for staying at home in the first place...right! Heat stress is a seriously dangerous thing...because you just don't realize that it is happening to you....yeah, yeah, I know...it's bloody hot...you feel like you are cooking etc...that's the good bit...you still know what's going on and are feeling it... Sooner or later though...if you push it too far, you flat out WON'T know! Like it or not, your simple judgments become impaired, your reactions slow down, and your brain fails to focus on all those things that you would normally be alert to - that keep you alive - merging cars, sharper than expected corners, pot holes that might send you careening into the trees mid-corner etc etc...That's heat stress - and it will kill you! The same thing goes for de-hydration - allow yourself to become dehydrated and you'll be feeling veeeery sick, head-aches etc...it aint fun and you won't be getting home from where-ever you are, if you get struck with it. I've found that the best way to avoid it is to drink and drink and drink and keep swetting like a pig. Really!...Stop swetting and it (dehydration) won't be far away. Stop and cool down - PROPERLY!...your mates wanna keep going...say good-bye, and cool down. If you must keep riding (long week-end away or whatever) and the heat is abominable, then feel free to completely immerse yourself in every river you go past, it does'nt take long...just jump in leathers and all...depending on how long it has been between dousings. The important thing is to keep your core temperature down...moving through the air while wet, acts like an air-conditioner. If you have'nt tried it, give it a try...it's a great feeling for a little while. One other thing that I would strongly warn against...Do not underestimate the distraction of the discomfort of the heat... If you are riding along and thinking - shit it's hot!, shit it's hot!, shit it's hot!, your head is NOT in the game...leaving you wide open to not seeing, noticing, or even being aware of something that you should - all because the heat is just so opressive it's all you can think about...you miss that car that did'nt see you, becuase you are overly distracted by the damned heat - and bang! Depending on your riding gear, you will need to vary your breaks and cooling off periods, of course... Anytime I am commuting home, and I know it's going to be beyond my own personal comfort zone - I step into the showers at work in my riding gear - boots and all for a few seconds and wet myself down pretty much fully. (I thank Pinx for THAT idea) <grin>... I'm usually dry by about half way home, but that is enough to get me there without getting too heat stressed. I ride the monash in Melbourne...On a 45c day, the temps on the freeway are around 52c off the rad surface...in the areas where I hit regular streets surrounded by cars while sitting at lights etc , it could easily be 55c+ coming off the roadway. In my own own experience, I've seen a bloke tootling along ahead of me go more or less straight ahead off the road instead of around a corner...and I have blacked-out myself on more than one occasion. (been riding - suddenly realized I was veering off the road just before hitting armco, end on...or have suddenly realized I'm further down the road than I was a second ago, 2 mins later.) I'm not saying anything new to most of you long range riders or seasoned commuters who've endured the heat, and have your own tricks of the trade... ...I've just started it off with a few tips of mine...so feel free to chime in with your own tips or thoughts. and stay cool. *EDIT...Here's a good link to follow as well...much good reading here! https://netrider.net.au/forums/viewtopic.php?t=29784&highlight=hot+heat+exaustion John.
