For coffee lovers, forget what you’ve heard about your cup of joe being dehydrating. A new study suggests it’s no more dehydrating that water.
Researchers at Birmingham University in the U.S. took a group of 50 healthy men and had half of them drink four cups of coffee a day for three consecutive days. The second group drank four glasses of water instead. Both groups were given a controlled diet and told not to engage in physical activity, other than walking. Then after 10 days the two groups switched.
After putting the subjects through a battery of tests designed to measure fluids in the body, researchers found no difference between the two groups.
But does it apply to women? The researchers aren’t sure, since women’s blood hormones could affect the results differently.
Findings were published in the journal PLOS One
on January 9.
Other good reason to love your morning coffee? In a 2012 study by researchers from the National Cancer Institute in the U.S., older adults who drank coffee -- caffeinated or decaffeinated -- enjoyed a longer life span than those who did not drink coffee.
In a separate study from 2012, researchers from Ruhr University in Germany found that coffee may take the negative edge off of the world, and focus your mind on positivity. A study in 2011 also found that women who drink two or more cups of coffee a day are less likely to get depressed. While it's not clear why this happens, researchers say it may be linked to caffeine's effect on the brain's chemistry. The findings, published in Archives of Internal Medicine, come from a study of more than 50,000 U.S. women.
