Another problem is actually seeing red in your urine. You look in the commode and see pink or strings of blood clots. Sometimes it can come from damage to the bladder. In any circumstance, you need to get to a doctor quick. I drum in the desert southwest.
Dehydration is a very big problem here.
Drink even if you are not thirsty. Your body does not sense the water loss adequately in very dry conditions to count on the thirst mechanism working.
