Great news for coffee drinkers around the world! A new study done in the US has found that coffee does not cause or promote dehydration.
A group of men were divided equally in the study. For the same number of days, one group of men drank coffee each day while the other group drank the same amount of water. At the end of the designated number of days, the groups were switched, the water group drinking coffee and vice versa, for the same number of days. At the end of the study, researchers conducted various fluid measurement tests that showed there was no difference in the level of hydration provided or taken away between coffee and water. For many years, people assumed that coffee could promote dehydration due to its diuretic effects. However, these studies conclude this is not the case.
Researchers thought women may be affected differently by coffee due to hormonal differences. When a study was conducted that included around fifty thousand women, evidence was found that depression was significantly lower in women that drank two or more cups of coffee daily. Experts think the reason depression is reduced is the impact caffeine has on brain chemicals.
Another great benefit found about coffee is increased longevity. Studies including older adults show that drank caffeinated or decaffeinated coffee every day live longer. Researchers are not sure about the reason for increased longevity due to coffee consumption.
