A cup of coffee or tea helps many people wake up in the morning, but they may also have health benefits later in life, according to recent research reported in Scientific American.

 One project by the National Institutes of Health studied the relationship between different kinds of beverages and depression, and found that coffee consumption was associated with slightly lower rates of self-reported depression.

A Chinese study found that adults who drink tea on a regular basis had a smaller risk of depression. Other research suggests that caffeine may play a role in preventing cognitive decline, but the evidence remains inconclusive.
