The average temperature of the human body is around 98.6 Fahrenheit, or 37 Celsius. A normal temperature can also drop to about 97.6 F, or 36.4 C.
I’d say the human body is more basic, or alkaline. However, our stomachs are very acidic so they are able to digest food and such. Our blood has a normal ph of about 7.35, which is fairly neutral.
