Riding in the heat

Discussion in 'New Riders and Riding Tips' at netrider.net.au started by bulby, Nov 30, 2012.

  1. Yesterday's scorcher heralded the long awaited coming of summer (to me anyway). And getting a mild heat exhaustion on the ride home yesterday prompted the questions: What did I do wrong? How do I prevent that from ever happening again?

    Good news for me, a quick googling solved all the mysteries. This article answers all my questions:- http://www.soundrider.com/archive/safety-skills/when_youre_hot.htm
    Thought I'd share it with you guys, if you haven't already read it / known all that.

    TLDR: "... insulate your skin from the sun and hot air, use evaporative cooling around your neck, and drink lots of water."

    And that's what I did wrong - Or rather, what I didn't do. I drank lots of water regularly, but that alone is not enough when ambient temperature is above 37 C. It was 40-ish yesterday and I was in my vented leathers with the helmet visor cracked open.

    Having gone through the article though, I have a few questions I can't seem to find answers to.
    1. With regards to insulating your skin, would wearing a rain suit over my vented leathers do the job? Or do I actually need to wear thick clothings underneath?
    2. The article mentions wearing a water-soaked t-shirt inside your jacket, but I don't imagine leather jackets would appreciate being wrapped around a wet t-shirt. Is there any way to get around this without having to buy a new jacket?
  2. I have a mesh jacket, one of those squishy things you wet and put around your neck & a Camelbak for really hot weather. You know you've just saved yourself from dehydration when you get through most of the Camelbak and don't need to pee :confused:

  3. My vented leathers work pretty well. Almost too well, actually. I have to wear my rain jacket to block the wind when it gets to 20 C or lower. The problem is on days like yesterday, the faster you go, the hotter it gets. Or so it felt anyway :dead:
  4. Bulby, Mesh jacket or perforated jacket lets the air circulate so wearing a wet t shirt underneath works. There are also specialist garments designed for this job and will last a bit longer than a wet t shirt. http://www.glaciertek.com/cooling-vest-product-information/

    Those neck things that Reesa mentioned look like http://www.personalcoolingproducts.com.au/cool_snakes.html you can get them at most camping stores.

    Also, while you do need to more water in the heat, you need to be careful because drinking too much water is as bad. Oh Reesa, what you mention about not peeing is also a sign that your kidneys are shutting down from too much water.

    Light coloured clothing is best as it will tend reflect the sun and heat, dark colours tend absorb the sun and heat.
  5. I wear a mesh jacket soaked in cold water. I stay cool for a while this way, (it even makes me feel cold) although depending on how hot and humid it is, the jacket can dry out fast, so needs to be repeated a few times during a ride.

  6. I use a mesh jacket and a Camelbak. Seems to work ok. Not as comfy as a cage with air con but it does the job
  7. I was wondering the same thing! Really regretted riding to work as an hour at 39C was pretty horrible. My boyfriend did 2.5hours and was in a lot worse shape. I wet my tshirt and because I have mesh in my jacket that helped a little bit when I was moving but not so much in bumper to bumper traffic. My bf asked in traffic if I was ready to try lane splitting :) But not confident yet for that unfortunately.

    Someone sent me a link to this: http://www.alibaba.com/product-free/110896218/ice_vest_cooling_pack_short_jacket.html No idea if it is any good though!
  8. ?? it's actually less than I usually drink
  9. I'm with Ametha; wear a mesh jacket and soak it in water at every opportunity

    Oh, and filter to the front at intersections to buy yourself some un-exhausted air :LOL:
  10. Definantly agree with hornet to. Clean air is a relief to exhaust fumes
  11. Yep, keeping up airflow is the best solution.
    So any opportunity you can find to safely get ahead of traffic - take it (whether it's legal or not).
  12. I have to admit - and to steal a line from the blackie - some of my ATGATT soul died yesterday as I saw the squids.

    I have a mesh jacket and gloves and only have a 30 minute ride but I was a puddle when I got home.

    Good idea about soaking the tshirt that would have helped me yesterday.

    Cheers Jeremy
  13. You just need the right gear ;)
    Still waiting for Tak to do the matching Kevlar shorts and singlet though.

    Or a breathable helmet for hot weather!
  15. I really just wanted to highlight that drinking too much water can be just as dangerous.

    In all honesty it wasn't until my wife told me of a couple of cases of recruits over hydrating that I'd even considered it an issue.
  16. I saw a pair of bikes on Citylink yesterday doing $1+. Two guys and a girl pillion; shorts, singlets, sneakers etc etc. I'm an ATGATT nerd, but I really couldn't blame them. It must have been pretty damn warm, and this was around 6pmish.

    But I couldn't help imagining what they'd look like if spread all over the road, so I couldn't bring myself to do it. Each to their own tho.
  17. I seriously considered shorts and Tshirt for the commute this morning, but we are supposed to get thunderstorms with the possibility of hail.
  18. Yeah still very interesting - I wasn't aware of that. Normally I down about 2-3 litres per day on any given day.
  19. From what my wife told me, these two recruits had downed something like 12 litres of water in a 4 hour period, thinking they were doing the right thing.
