3. Helps to Improve Mood
Anyone who relies on coffee to make the morning bearable probably already knows this one, but coffee really can have a significant effect on mood.
Much of that effect seems to be connected to the caffeine in coffee, particularly as caffeine can help to make people feel less fatigued and make them more alert.
One study conducted a meta-analysis looking at the outcomes of a large number of studies on caffeine and mood. This study was very significant because the authors looked at the outcomes of experimental studies into caffeine.
The authors found that caffeine was associated with improvements in mood for participants that were sleep deprived and those that weren’t.
