Increase Water Intake
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Drink at least 8 cups (64oz) of water daily. A warm glass of water first thing in the morning may be especially effective for stimulating bowel movement.
How it works
Dehydration is a leading cause of constipation - insufficient fluid causes the colon to absorb too much water from stool, hardening it. Adequate hydration keeps stool soft and easy to pass.
