Music

Play Baroque music quietly in the background while studying
An interesting study on music and silence was done at Stanford University where they set up three identical rooms full of plants. In the first room, there was complete silence for three months. The second room was filled with loud rock music for the three months and the third room had baroque music pumped in. At the end of the three months, the plants that were in complete silence were still just normal healthy plants. The plants with the rock music were shrivelled and dying. And the plants with the baroque music were flourishing and growing more than anyone had thought possible.
What was even more amazing about this room was that every single plant in the room was growing towards the speakers. Now, your brain isn't a plant, but if this kind of music enhances plant growth, maybe it also enhances brain function. You don't have to listen to this kind of music all the time but it can be very, very useful when studying.
If you're studying maths or learning a new language, listening to Mozart's music can be very helpful. Gordon Shaw from the Californian University in Irvine has scientifically proven that listening to Mozart for ten minutes will increase your ability to learn maths and a new language for approximately thirty minutes.
