Yes it is quite clear what you are saying. What you are saying is wrong for reasons explained to you in depth that you have not refuted. Just continuing to assert something without showing any signs of understanding what is being said to you (and indeed without even engaging with the discussion) is not helpful. Provide some sort of substantial rebuttal, or accept that your idea is incorrect, get over it, and move on.
I assume you’re referring to plain tap water, not mineral water here, so if you’re sweating a lot and not drinking enough electrolytes, you could feel thirsty. The general recommendation is to drink water + salt, but that doesn’t taste very good and you also need to hit the right ratio.
What I found interesting and might be helpful for you was what Thor Heyerdahl observed on his Kon-Tikki journey: in the first days, the group drank more clean water than they’d calculated (they got new water from collecting rain), until one morning they accidentally discovered that spray from the salty ocean water in their porridge tasted good enough to eat, and gave enough salt so that they only needed to drink enough clean water, no longer excessivly.
So maybe you should eat some salty foods before or during the exercise - salted peanutes, bretzels - to compensate for the unsalted water.
I can remember when the salt tablet dispenser was a fixture next to drinking fountains in factories. Then they suddenly disappeared, maybe in the 70’s
I’ve been wondering of one of the sports drinks, like Gatorade, would be effective somewhere in the workout.
Gatorade (scroll down to Nr. 1)* and other isotonic drinks are extremly expensive for being basically mineral water with lemonade (lots of sugar), which can also be a problem if you’re not exercising like a pro sportler, just like a hobby sportler, you take in more calories through the sugar than you burn.
Doctors over here recommend the ideal cheap isotonic drink as mineral water mixed with apple juice (not fermented, just juice) in relation 3:2 roughly.
Isn’t thirst your body telling you your water to electrolytes ratio is too low? How can more electrolytes from whatever source quench it?
Never encountered jamie before, have you?
? Thirst means first water, because under usual circumstances, electrolytes come with the food (as does part of the water, too). If it’s a hot day or you exercise a lot, you feel more thirst; if you eat a lot of water with your food, you will feel less thirst.
Actually, I think it’s more likely counterproductive (though again, to such a small degree that it can’t actually be measured). If you’re exercising enough to sweat at all, then your body is actively trying to get rid of heat, by sweating. Moving sweat out of the body takes energy. By cooling your stomach with ice water, you’ve just reduced the amount of heat your body needs to get rid of, therefore reducing the amount of sweat required, therefore reducing the amount of energy your body uses.
So, unless your weight-loss plan is “Lots of shivering, but no other exercise”, chilling your water is a step backwards.
Is it just a question of needing to wait a few minutes for your body to absorb all the water, and get the signal that it’s not dehydrated anymore?
(psst. In scientific circles, the ‘feeling of being dehydrated’ is called ‘thirst’, unless you’re referring to some more exotic symptoms)
For me, when this happens (insatiable thirst, either after exercise or a hangover), it has to do with the amount of salt. I sweat profusely. I’m not overweight, but I have recorded up to 7.5 pounds of water loss after an 8.5 mile run (and that includes a brief stop at a water fountain.) I make sure to put in salt (about 1/4 teaspoon or so per pint) with some sugar (dextrose) and water for my recovery drink, otherwise, my thirst doesn’t feel properly slaked.
No. * Lowering your core temperature has a moderately positive effect when trying to burn excess calories. Can drinking chilled water produce this effect? Sure. However, drinking chilled water and then turning the thermostat up *negates this. As does putting on a sweater. As does crossing your arms. As does light excercise. This seems to be the portion that you’re not grasping.
Its somewhat similar to people who think that all they need to do is turn the A/C down to 62F at night and they’ll be losing weight while they sleep. That extra-thick comforter on the bed? Well, who wants to sleep cold!
Actually if you review that cite I provided a while back it’s far worse than this. In very approximate terms, a skin temp of 20C (68F) is the key. Core temp and skin temp work together to determine the trigger point as to when your metabolism will increase to keep warm. To get your metabolism to increase you have to have a skin temp less than about 20C combined with enough cold water to drop your core temp appreciably. 20C sounds like a lot, but bear in mind that is your skin temperature not room temperature. Even light clothing will permit your skin temp to be way warmer than 68F unless you are somewhere very cold.

I understand what is being said, I am just having a hard time understanding why there is all this seemingly contradictory data out there. I don’t claim to be any expert but I post this link to you as a legitimate, scientific study that clearly shows a thermogenic effect from drinking cold water.
The study was actually on the thermogenic effects of drinking water, but a large percentage (40%) of the thermogenic effect was due to raising the temperature of the water. Now what am I missing?
It’s a relevant study. However, there is nothing in the study to indicate the temperature conditions under which the subjects were tested. They may have been cold, and certainly they weren’t exercising. Note also the abstract linked off namely
which found that vasoconstriction does occur when one drinks. If one vasoconstricts (increasing insulation) and also expends additional energy equivalent to that required to warm the cold drink one would end up warmer than one was to start with, which can’t be right. Perhaps one’s metabolism undergoes a drop later.
If the OP wants the cheapest and most effective way to replenish body fluid, there’s the ORS (Oral Rehydration Solution), developed by the WHO*
(This recipe, the first I found, is in metric, but there are also recipes in Gallons).
You can also add the salt first and taste-test: it should be as salty as tears.
You can also add orange juice and /or half a mashed banana.
The recipe says “boiled water then cooled” because it’s intended for areas where water isn’t safe. If your tap water is clean, just use that.
- The WHO developed the ORS for diaherrea in 3rd world countries, and with the simple recipe thousands of lives have been saved during cholera and other diaherra diseases that dehydrate people quickly. These people don’t think of sports; nevertheless, the basic need for rehydrating a sportler after a long and sweaty exercise are similar.
I do. Between working in a warm environment and spending 45 minutes to 2 hours at the gym everyday, I get pretty thirsty. I go through 7 to ten litres of water a day; any less than that and I feel ridiculously parched. I have been tested for diabetes and a few other things, and nothing ever shown up. I do have to be careful about electrolyte balances and such, but on the upside, my formerly acne-prone skin is no longer so.
However, I have no illusions about cold water burning calories, or desire to skip my evening workouts to sit in a cold room drinking cold water just to burn of the equivalent of a half cup of orange juice.
Have you tried drinking mineral water instead of tap water? Thor Heyerdahls observation that drinking liters and liters of pure water just meant that they sweat it out as quickly, leaving them still parched, but a bit of salt in the breakfast meant that their consumption dropped to the normal 3 liters and they felt satiated?
Teaspoons are metric?
