Protect the back of the head/top of the neck from too much sun. That is the bit that can dangerously send your bodies various regulators (including heat but much more) into a spin if itself gets overheated, potentially deadly, potentially brain damage. Doff the helmet occasionally and drip a bit of water over it. Even better hang a damp hanky over there.

Or wait until dusk. Cooler then too!
(as our dew point is quite low, sweating is still an effective way of keeping cool. The challenge is keeping the water up)

I have pretty decent cycling kit, especially the jersey that is quite well made, it seems to do a great job of keeping me cool - but it is very thin, which is by design. Things like that are really important.
Keep drinking enough water, but don't drink excessively either. Make sure you use sunscreen. The others have already given good suggestions.
I don't mind the heat too much, I've ridden fast in 36C or higher before, so I'm fairly used to it. I find the most important thing is to keep the speed up, if I slow down to much I start to overheat.

One question re sunscreen. According to my weather app UV is really low around the times I'm riding - the lowest on the scale. I've been riding without sunscreen for months with no sunburn. Is there some reason I don't know at that time of day?

I ride almost exclusively as a commuter so it's a choice to put up with the heat or lose the km's.Calvin27 wrote:Above 35deg, I just wait until the afternoon. Some days however are too hot to ride and that's when I crank the split unit and get the trainer out.

No. I tend to get burnt if I'm late for work. But it's a rare day when I'm home before the sun is under the yard arm and, while hot, the sun is not such a problem (heat or UV wise)AlexHuggs wrote: According to my weather app UV is really low around the times I'm riding - the lowest on the scale.

Serious question, how do you stop sweating? I drip all the way to at least 9.45am. I've tried cold showers, allowing more time etc. It seems the only thing that works is 45 minutes in an air conditioned office.AlexHuggs wrote:I ride almost exclusively as a commuter so it's a choice to put up with the heat or lose the km's.

In prior years I've had an issue with getting itchy welts from sun exposure despite not getting sunburnt, and having to resort to long sleeve jerseys with high collars.
This summer I've been expecting a recurrence and have been pleasantly surprised. And I'm not getting overly tanned either. Been using it n arms, legs, back of neck, ears and face below the eyes I've avoided eye level and above to stop getting irritated eyes from perspiration carrying it in. I've dealt with that by wearing a cycling cap under my lid.
However, there is a downside. I missed a spot up near my sleeve cuff on the weekend. It got more than a little burned.

A warmish shower and then a simple pedestal fan cooled me down after riding home in the heat yesterday. I also wore a long sleeved UV shirt soaked in water so the evaporative effect kept me cool initially. Re-wetting the shirt got less pleasant as I rode though as my water bottle heated up so it felt like I was splashing myself with a kettleRyanA wrote:This was discussed last year: viewtopic.php?f=41&t=87366" onclick="window.open(this.href);return false;Calvin27 wrote:Serious question, how do you stop sweating?

Don't see it in the thread cited above, but read a response to this question by an anaesthetist. Problem with jumping into a cold shower while you're hot is the capillaries in the skin constrict, restricting blood flow and trapping the heat in your core. Even though your skin feels cool, you're not really cooling down that much so when you get out of the shower the blood vessels dilate and the body starts to dump that excess heat again - hence the sweating. I have a 20km ride each way to work so I can't avoid sweat. I make sure I get to work plenty early, ride slow the last km or so, cool down at work then have a shower. A tepid shower might also work since it doesn't cause the skin capillaries to constrict, but since the shower at my work isn't heated I don't have that option (it's a cow in the winter). Haven't had any problems with sweating. But my workplace is pretty good for that relaxed start and YMMV.Calvin27 wrote:Serious question, how do you stop sweating?

I've tried the 30-second cold shower; that doesn't work. Cool enough to close capillaries but not enough to cool you down, so you start sweating shortly afterwards.

The difference between having a cold shower and jumping in a pool to cool down is pretty big. Sounds like it's all about getting the core temp down and a cold shower just doesn't do it - I guess unless you are in for long enough. For some reason though a cold shower is way less pleasant than the shock of a bomb into the pool when you are stinking hot!Howzat wrote:I'd bet that if you spend a sufficient time in the cold shower it will cool you down, capillary dilation or no.

I have found on my commutes that the hottest afternoons are some of the quickest rides. Here, most of the hottest days are accompanied by a strong North Westerly wind which is a rare opportunity for a tailwind for me. Smash out the flat with the tailwind and then back off cranking up the hill at the end. On any other hot ride though its a matter of regulating my output so I don't overdo it and keeping the water input going.

Sounds trite but the obvious answer is to get cooler. If you wear body-fitting lycra then try soaking it sometime into your journey. Get you get under a shower, a sprinkler, whatever. I have found that for forty five minutes in my case the whole of the surface under the lycra feels not just not hot, but actually cool. It's taking away the heat far better than just sweating.Calvin27 wrote:Serious question, how do you stop sweating? I drip all the way to at least 9.45am.

Obviously you have to find a soaking point but a water fountain will do for the top if you strip it off. And the length and temperature differential will depend on things like humidity, speed. My forty five minutes is in Perth summer weather and traveling at a modest 10kph.
Anyway, find a soak point somewhere and give it a try. If nothing else it FEELS great.

I carry an extra (third) water bottle when it is above about 38, I have a removable bottle holder which goes on the handlebars. Also I part freeze my water bottle, the third one I freeze solid on hot days. No warm water for me (in fact I part freeze my water bottles in the middle of winter, I like my water cold).
I soak the jersey in water and know of 2 places to do this on the way home, it helps a lot in controlling heat.
I know this is the wrong thread, but . . . helmet is off for as much of the ride as possible. I don't need a head warmer.
Mainly just drink a fair bit of water and make sure you don't overheat.
