Study Reveals Health Benefits of Drinking More Water
Staying hydrated is widely recognized as essential for health, but a new study delves into the specific benefits of drinking plenty of water—revealing more advantages than you might expect.
Researchers at the University of California, San Francisco (UCSF) analyzed 18 prior studies, with a median of 48 participants per study. Most of these studies demonstrated benefits associated with increased water intake.
Unveiling the Hidden Benefits of High Water Consumption
Previously, research on consuming large amounts of water—such as exceeding eight glasses daily—yielded mixed results, influenced by variables like age, sex, and environmental conditions. This review highlights that drinking more water offers benefits beyond just staying refreshed.
“The volume of rigorous research was somewhat limited, but certain areas showed statistically significant benefits,” says UCSF urologist Benjamin Breyer.
“To our knowledge, this is the first study to broadly evaluate the clinical benefits of water consumption,” notes UCSF urologist Benjamin Breyer.
However, the advantages of drinking more water were not always clear in the studies reviewed—only 10 out of the 18 analyzed showed clear, measurable benefits.
Key Health Benefits of Increased Water Intake
The most significant findings were that higher water intake reduced the risk of kidney stones and supported weight loss. Individual studies also linked increased water consumption to preventing migraines and urinary tract infections, as well as helping manage diabetes and low blood pressure.
While none of the studies reviewed were rigorous enough to establish causal relationships, they provide insight into various health areas where hydration may be beneficial.
The negative effects of insufficient hydration are more scientifically established. Dehydration is associated with shorter lifespans and a higher risk of chronic diseases. Water plays a crucial role in regulating body temperature and eliminating waste, making consistent replenishment essential.
WHO Guidelines for Daily Water Intake
The World Health Organization recommends daily water intake of around 3.2 liters (approximately 14 cups) for men and 2.7 liters (11 cups) for women in temperate climates, though individual needs may vary based on body type and environment.
As always, consulting a healthcare provider or trusted health sources is the best approach for personalized advice. Paying attention to your body’s signals can also guide appropriate hydration, as highlighted in prior research.
“Dehydration is clearly harmful, especially for individuals with a history of kidney stones or urinary infections,” says Breyer.
“Conversely, those who experience frequent urination might benefit from reducing their water intake. Water consumption isn’t a one-size-fits-all solution.”
