Do you drink a cup of coffee to get going in the mornings, or one in the afternoon to stay awake? You might be doing the right thing, and Jamie Hale explains why.
Okay, you might think, so let’s just drink loads and loads of coffee and increase performance. The more, the better. Wrong. According to research results for example reported on the homepage of Mayo Clinic, 200 to 300 milligrams of caffeine, which equals two to four cups of coffee, is an appropriate dose. Drinking more than that, which would be more than 500 or 600 milligrams per day, can cause a lot of undesirable side effects like insomnia, nervousness, or stomach upset. Some people are more sensitive to caffeine and thus are recommended to consume even less.
So a cup of coffee or two or maybe even three or four is a great thing to enhance your focus and improve our vigilance. Drinking more, however, yields the contrary effects of the wanted ones.
