Since I left prison, I haven't drunk any soda. The commisary doesn't sell it in Yuba County Jail. The jail provides two containers of hot water and refills them twice a day. Therefore, I'm able to drink warm water all the time.
A librarian once told me that it's better to drink warm water than cold water when the weather is hot or when I'm thirsty. He said that if we drink cold water, our digestive system, which is warm, will regulate the cold temperature. If we drink warm or room temperature water, it won't shock our system and will quench our thirst.
Since then, I've always prefered drinking warm water over anything else. I know I'm healthier because I drink plenty of water daily.
Are you drinking enough H2O?
