This some times happens to the military on the 4 day marches in Nijmegen - being told to "Drink" water every 5 min when its hot.
Its a good point to raise over hydration is bad too... watch for the signs compensate if nothing els.

I managed to get my back sunburned and a touch of heatstroke a couple of weeks ago.
I very rarely don't have a shirt of some sort on in the sun but loaded the car at home for a barbie at L Doon without one.
Everyone was ready for the off so I remained shirtless,drove off and got on with the manly fire making and cooking there with a good breeze blowing.
It wasn't until we got home I realised I'd been burned,I had a shower and sat on the chair with the laptop.
My feet felt cold,so i thought a cuppa was in order.
I got out the chair and began shaking,not shivering but really shaking.
Got up to bed and needed the 'lecky blanket on and kept it on for some hours.
I've had this abroad once before but that was in temps of 40+ celsius.
I was actually more ill over here than there.
Very easy to get caught out.

and Paste a good read for the new members who might be heading out soon.
and a refresher for the old sweats.....pun.
There are some things (I believe cant be said enough)** and having just spent the day at my eldest school sports day in a cloudy but hot day...........
The Signs and Symptoms of Dehydration
Symptoms of dehydration usually begin with thirst and progress to more alarming manifestations as the need for water becomes more dire. The initial signs and symptoms of mild dehydration in adults appear when the body has lost about 2% of it's total fluid. These mild dehydration symptoms are often (but not limited to):
* Thirst
* Loss of Appetite
* Dry Skin
* Skin Flushing
* Dark Colored Urine
* Dry Mouth
* fatigue or Weakness
* Chills
* Head Rushes
If the dehydration is allowed to continue unabated, when the total fluid loss reaches 5% the following effects of dehydration are normally experienced:
* Increased heart rate
* Increased respiration
* Decreased sweating
* Decreased urination
* Increased body temperature
* Extreme fatigue
* Muscle cramps
* Headaches
* Nausea
* Tingling of the limbs
When the body reaches 10% fluid loss emergency help is needed IMMEDIATELY! 10% fluid loss and above is often fatal! Symptoms of severe dehydration include:
* Muscle spasms
* Vomiting
* Racing pulse
* Shriveled skin
* Dim vision
* Painful urination
* Confusion
* Difficulty breathing
* Seizures
* Chest and Abdominal pain
* unconsciousness
Be aware that these are not the only symptoms of severe dehydration that may manifest in response to dehydration, these are simply the most common. Symptoms of dehydration will differ from person to person because the body is a complex network of systems and everyone's body is different. When these systems are disturbed due to loss of fluids there will be several common symptoms shared by most bodies, but there may also be unusual or unexpected responses depending on the particular person in question. Age also plays a part in the manifestation of symptoms. Signs of dehydration in a child will not be the same as those experienced by a teenager, adult or in the elderly. Dehydration prevention is the best treatment for every age group. heatstroke is always around the corner.

I drank more than three times the usual amount of water at judo last night. My kit is usually pretty damp at the end of a session, but it was wringing wet at the end of that one.
It ain't arf 'ot, mum.

Look up myths and water on Google for the scare stories about dehydration. If the body tells you you are thirsty then it is obviously not too late, the body is truly wonderful at looking after itself and if it needs water it will tell you so. Check your pee if you want a gauge of your water needs. It is not unreasonable to be thirsty on a long walk and in a way can add to the experience. Sucking at a water bottle all the time is not necessary.
I'm finished with cutting the grass,refuse to do it again on the grounds of looking after my health first, i've ended up burnt and feeling carp.
i'm staying indoors or in the shade of a wood only from now on.
Oddly that could have been my post too
That what reminded me.
You can be fooled by thirst response. I once drank 9 litres of pure water because I was thirsty. that was dangerous as I really needed electrolytes. I Cld have washed out.
I have naturally low blood.pressure. I've blacked out before now after a long hot walk. It might have been down to low pressure and it being made worse due to low blood volume. A potential result of dehydration. It's kind of the reason the nat blood service make you drink water before giving blood.
Try half flat, full sugar coke with water or the same mix of fresh orange juice and water but with a pinch of salt. I've heard those two mics are just abt isotonic to get into system quicker. Think it's abt 5% solution.

A timely and important post. Thank you for the reminder Shambling Shaman. One time, I ended up at the 5% loss point despite carrying and drinking 4 litres of water together with a litre from the only trickle we could find on the mountain one long, hot day in the Pyrenees. It was very, very unpleasant. Another time ,my wife ended up in a French hospital after a long day in the Massif Central when she fainted in the shop where we'd gone to get water. And we are far from being novices- it can happen even to the well prepared.
Your pee is not a reliable way of checking yourself out, you could have a UTI, may not have drunk enought the day before, you may not realise how much you have been sweating etc. You'll get a dry mouth from heavy breathing, thats a different thing from being actually thirsty. Nobody said if you feel thirsty its too late, but its a good way of spotting the start.
Monitor your input is a very safe way of keeping juicy.

I have just got home form a two day canoe camp trip with a school group, we drank enough. Eating food helps too.
They listened about long sleeve shorts and swam/paddled a lot so no probs.
It was 25degs at 10pm ! on Loch Ard.

I'm very careful about hydration, it's not unknown for me to drink 5-6l of water in a 9hr shift during the summer.
of course the temperature can top 120f (in the shade) with 100% humidity.
If you are sweating heavily, and drinking a lot though you need to be mindful of electrolyte levels.

Try Nuun tablets.
a) they taste good
b) specially desined for electrolites etc
c) come in a great tube that I use for tinder when emptied!

I find that sipping water through the day is the best way to rehydrate. The body cannot handle drinking a lot of water all at once. Hyponatremia is a risk if you drink a lot of water all at once.
I am not sure what you mean, do you mean the volume or whats actually in the pee? If you meant the former then you could have a point but as for the latter it's a very reliable measurement of hydration. https://docs.google.com/open?id=0Bz_S8-XOmkWBbnJtR2c3akVpUzA
Urine color or specific gravity is affected by MANY factors. Neither is of any use to a diabetic when trying to determen hydration levels; nor is thirst as we are ALWAYS thirsty.
A good easy to reproduce isotonic is 50% orange juice and 50% water with a pinch of salt. The idea is that this mix of 50-50 is reasonably close to the consistancy of blood and with the salt mix is apparently far more easily absorbed by the interstitial tissue. It gets into the blood quicker than going through the digestive system and then the bladder and out. Salt is really sodium, whereas most of the substance we lose in sweat is potasium. so plenty of bannanas and potato skins. A cracker I was taught about general health and wellbeing regarding water is, The solution to polution is dilution.
No, there is five to ten times as much sodium in sweat than there is potassium.

Personally I think there are no absolutes to this, and that it depends upon the individual and physique.
Following the current scare mongering advice, I would end up carrying far more weight in water than I need to somewhat decreasing the object
Yes my urine does sometimes get somewhat dark, yes I do sweat like the proverbial pig, but I have survived these fifty odd years without dehydration nonetheless.
