Grand Entrance of Sunlight Energy

I began to wonder about how people can get so much energy for a short amount of time while they are outside, that is not drinking a ton of caffeine beforehand. See if you put your hands in front of your face, where they are directly pointing towards the sunlight, then the sun's rays would begin to enter your body and energize your spirit both internally and externally. But you only have to do it for a minute.
