so if 15% loss is usually fatal, then for me that is 2.4 gallons which is 11 litres or 384 ounces, so if my body used 1 litre a day then i could go for 11 days before getting 15% dehydrated.
The worst symptoms I've had were numb/tingling legs after 3 days which could be 6% fluid loss.
You just read everywhere that 3 days could be fatal and when I've tried it the symptoms get really uncomfortable and you start to fear for your life a lot.
I guess I could go for longer than I think if I am willing to put up with the bad symptoms, its just knowing when to stop.
What are the chances something freak might happen and your heart just gives up, I guess it is similar to water fasting in that as long as you don't go too long it is fairly safe.
best thing I can do is do lots of shorter fasts to get my body used to it and keep learning as much as I can.
Dehydration symptoms generally become noticeable after 2% of one's normal water volume has been lost. Initially, one experiences thirst and discomfort, possibly along with loss of appetite and dry skin. This can be followed by constipation. Athletes may suffer a loss of performance of up to 30% and experience flushing, low endurance, rapid heart rates, elevated body temperatures, and rapid onset of fatigue.
The symptoms become increasingly severe with greater water loss. One's heart and respirationrates begin to increase to compensate for decreased plasma volume and blood pressure, while body temperature may rise because of decreased sweating. At around 5% to 6% water loss, one may become groggy or sleepy, experience headaches or nausea, and may feel tingling in one's limbs (paresthesia). With 10% to 15% fluid loss, muscles may become spastic, skin may shrivel and wrinkle (decreased skin turgor), vision may dim, urination will be greatly reduced and may become painful, and delirium may begin. Losses greater than 15% are usually fatal.
