1 If you’re looking for an energy boost, coffee has the biggest effects, and it’s no doubt the strongest.

I usually drink a cup or two of green tea every day, and one or two coffees every week.Ī cup of green tea contains 25mg of caffeine, a cup of black tea contains 42mg, and a cup of brewed coffee contains 108mg, so coffee definitely packs the biggest punch out of the three beverages. Last week I mainly experimented with coffee, green tea, and black tea. Here’s what I learned! What I discovered experimenting with coffee and tea To measure how caffeine impacted my learning, I mainly observed how caffeine affected my energy and focus (it would have been difficult to measure information retention), and discovered a lot about how caffeine can affect your productivity. Last week I watched 70 hours of TED talks as a productivity experiment, and over the course of the experiment I deeply explored how caffeine helped, and hindered my ability to learn. To get as much energy out of caffeine as possible, don’t drink too much, drink lots of water, drink caffeine over a longer period of time (and wait a bit before your second cup), stay away from sugary energy drinks, don’t drink caffeine on an empty stomach (or first thing in the morning), and eat very well if you consume caffeine. Takeaway: Caffeine can make you a lot more productive, but only if you drink it right.
