The Claim
In adults with high baseline copeptin levels, increased water intake is associated with the greatest reductions in both copeptin and glucose concentrations among those in the top tertile of baseline copeptin.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among adults with the highest initial levels of copeptin, drinking more water is linked to the largest decreases in copeptin and glucose levels.
See the scientific wording
In adults with high baseline copeptin, the greatest reductions in both copeptin and glucose occur in the top tertile of baseline copeptin, suggesting that individuals with the highest baseline vasopressin activity may benefit most from increased water intake.
When a person drinks more water, their body detects less salt concentration in the blood, which tells the brain to stop releasing a hormone that triggers stress responses. This reduces another stress hormone that tells the liver to make more sugar, so blood sugar levels drop.
What the research says
1 studyPeople who drink very little water have high levels of a stress-related hormone called copeptin. When they start drinking more water, their copeptin and blood sugar drop the most — meaning they’re the ones who benefit the most from drinking more water.
