I thought I was drinking enough water but on June 10, a nurse practitioner questioned me and said she was confident I was short-changing myself. Despite some older advice to drink 8 ounces 8 times a day, she said to try for 50 ounces a day. That was on June 10. I have a 16 oz. mug I like and I have had the first of three mugs of water first thing in the morning each day since then. I am quite positively impressed at how good I feel with this greater input of water.
I looked up what % of blood is water and found that 55% of blood is plasma and 90% of plasma is water. So, 45% of my blood is water. High temperatures cause me to loose moisture. There are many articles about people, especially older people, getting seriously dehydrated. There seem to be several contributing factors but a major one is that thirst is not as easily sense by older people. I remember that Lynn's stepdad taken to the hospital in an emergency helicopter for dehydration.
A colleague who taught science teachers once said that human bodies work basically on the principles of water chemistry.
I suggest you work to be properly hydrated every day.
