Good to know
The US National Academies set an Adequate Intake for total water of about 2.7 L a day for women and 3.7 L for men, from all drinks and food. About 80% usually comes from drinks.
Needs rise with heat, exercise, vomiting or diarrhea. GLP-1 labels warn that dehydration from stomach side effects can affect your kidneys — if you can’t keep fluids down, contact your doctor.
