Coffee, as most of us know and appreciate, stimulates the central nervous system, making us feel more alert. It also can boost memory, improve concentration and mental health and has been associated with a possible decreased risk of alzheimer’s disease and certain cancers. But that is in moderation. Coffee can also trigger insomnia and anxiety.
The Huffington Post has dug up 10 lesser known facts about coffee, including that decaf isn’t the same as caffeine free and that it takes 30 to 60 minutes for caffeine to reach its peak level in the blood. The body eliminates half of the drug in three to five hours. People also process caffeine differently based on gender, race, whether they smoke and what type of birth control they use. Dark roast coffees have less caffeine than lighter roasts and Finland consumes more coffee per capita than any other country.
