Coffee increases alertness and concentration
Caffeine is known for its stimulating effects and, in reasonable quantities, it increases alertness and concentration. However, exceeding four cups per day will have the opposite effect: anxiety, inattentiveness and nervousness.

Coffee contains antioxidants
In Norway, where people are huge coffee drinkers, coffee is one of the population’s prime sources of antioxidants. Recent findings even indicate that coffee contains more antioxidants than tea. The good news: antioxidants are not related to caffeine, so drinking decaf is just as beneficial.

Coffee helps the digestion
A coffee to cap off a meal? Excellent idea. Caffeine increases the secretion of saliva, promotes digestive enzyme production and improves bowel regularity. It should be avoided, however, if you have a sensitive stomach.

Coffee promotes wakefulness
Yes, caffeine can be useful when you suddenly feel drained. The effect takes place 30 minutes after drinking coffee and lasts from four to six hours, depending on the person. After this time, half the caffeine has been eliminated.

Coffee increases mood
From the first sip, caffeine begins to release dopamine, the pleasure hormone. If you start the day on the wrong foot, a small coffee can immediately put you in a good mood.
