One of the scary aspects is that your thinking is likely to be impaired and leave you more exposed to the dangers. Applies at the other end of the spectrum with hypothermia too. I've had a narrow miss with that when I became very sleepy on a mountain pass in snow and found myself thinking that forty winks in that handy snow bank would be a good move. Fortunately a tiny voice deep in my mind persuaded me otherwise.I'm not going to lie...I got a big fright, especially thinking of what may have happened if I'd ignored the warning signs & just kept going....
Yes!!!...couldn't agree more. I was aware something was wrong physically & also noticed my brain feeling hazy. It took all my concentration to figure it out & still to this day, I don't know how I made the connection to the doco.One of the scary aspects is that your thinking is likely to be impaired and leave you more exposed to the dangers.

Same here. I was dehydrated and exhausted and sitting under a tree falling asleep. It was that little voice that got me to seek help.Fortunately a tiny voice deep in my mind persuaded me otherwise.
Hi I can’t open while on WiFi in Spain. What are the main points?I came across this study today and it caught my eye because of the recent heatwave in Spain. I suffered my own heat event in Italy 3 years ago and it is memorable in the speed that it took hold of me. I'm starting the Norte in a week and I'll be evaluating temps AND humidity along the way.

I'm in the UK too and had the same problem. It's a common issue with many American news sites which block users in the EU and UK. I used a VPN to read it.Unfortunately, I get the message that the article is not available in my country (UK). is there another way of accessing it?
In my own experience, I've found that it's more a case of after a first heat attack, realising that the susceptibility to them is there.Be careful! Once you've had one heat injury it can make you more susceptible to future ones!

I believe the general 'rule of thumb' is that it is medically Dangerous to be outside when the 'temperature' is above 35C. Remember that the temperatures quoted by the meteorological people are for thermometers located in the shade approx 1 metre above the ground in a special 'box'. In the full glare of the sun it's gonna so much more than that.I came across this study today and it caught my eye because of the recent heatwave in Spain.

New research on young, healthy humans found the body begins overheating when exposed to temperatures and humidity lower than previously believed.theconversation.com
I'm up in the North East Piney Woods of Texas and have been experiencing the temperatures you're talking about. I have been working outside in this and while it is "warm" the biggest thing for me is take it slow and stay hydrated. I'm 62 and in fairly good condition but each person is different. The studies I have seen suggest that to fully acclimate to a new environment it takes two weeks sadly this is not an option if someone is walking right into the mouth of the lion.I live in Texas and it has been at least 38 C or above for about 2 weeks now with recent temps getting to 40 or 41 C with a "feels like" temp of 43 C some days. All of this with around 50% humidity. It is impossible to do anything outside. I say this as someone who has lived here my entire life and is very used to high humidity and high heat. This has been unbearable. Stay safe out there.
88°f and 100% humidity will make sweating ineffective at cooling the skin, leading to heat exhaustion and possibly heat stroke. Temps over 88°f have a lower humidity threshold, for instance, 100°f at 60% humidity. Bottom line, be careful, hydrate, seek shade, live to finish the journey.Hi I can’t open while on WiFi in Spain.

Thanks for the summary. You beat me to it.For those unable to access the article this graph summarises the results of their controlled experiment to define a “critical environmental limit” for young, healthy subjects. Below that limit, the body is able to maintain a relatively stable core temperature over time. Above that limit, core temperatureants began to rise - in other words the point at which their body cooling system could not cope. It is important to recognise that the participants were incolved in minimal activity similar to "cooking and eating". Throw into the mix normal camino activity and the results are very scary.
We in Australia are accustomed to high summer temperatures - we had one daily maximum in my hometown of 47c last summer, and 40c+ is not at all unusual. But our humidities on such days are very low indeed.

@MichelleElynHogan, were you responding to a particular post here, or making a more general comment about the study itself? I ask, because my reading of the article is that there were objective measures developed and used to test individuals' heat stress response. My view is that measuring the point at which an individual's internal temperature started to rise would have eliminated any subjectivity on when they were unable to 'maintain a relatively stable core temperature over time'.All of this is subjective as heat / humidity effects each individual in a non-linear way. ie, some have greater tolerance than others. However, as you have had a previous experience, it may be wise to take greater care, raising concern for susceptibility.
The study itself expressed that this "represents the average critical environmental limit for young men and women." A person can therefore conclude that an "average" would include variations from one person to the next. My conclusion is that each person can be at a different level and the limit can be higher or lower but be safe and don't bet your life on your limit being higher.@MichelleElynHogan, were you responding to a particular post here, or making a more general comment about the study itself?

There are several considerations that might create some uncertainty about what is dangerous, such as the study being conducted on young fit individuals undertaking what might be seen as relatively undemanding activities indoors, compared to walking outside, potentially without shade, which is what most of us do on the Camino. I would suggest all of these things indicate one should be even more conservative about assessing when it becomes dangerous to walk.
On this, the US National Weather Service suggests that Heat Index values can increase by as much as 15F (~10C) where the activity is conducted outside without shade - conditions that most of us face walking on the Camino.
All this goes to the conclusion that across much of northern Spain over the next few days, the maximum daily heat indices will be above the point that can lead to dangerous heat disorders with prolonged exposure and/or physical activity in the heat.
It would be unfortunate if someone reading your post were to take it that they could rely on some subjective view of their own heat tolerance to keep walking in such conditions, rather than avoiding walking, or planning to take a break during the worst heat of the day.
Wow. I'll just go inside now then. Instead of finishing my second beer and cycling home.I believe the general 'rule of thumb' is that it is medically Dangerous to be outside when the 'temperature' is above 35C.
