Researchers led by Prashant Kaul of the University of Kentucky, investigated whether meditation could help people become less tired in the afternoon.
The students were asked to undergo a series of tests and then have their responses measured. The study found that alertness was the highest after meditation, followed by caffeine and then exercise. Napping had the worst results.
The findings of Prashant Kaul were recently submitted to a conference for the Society for Neuroscience.
Previous studies have shown that when meditating although people are awake their are similar brain patterns to sleeping.
Some adepts in meditation are known to need very little sleep having become able to draw in cosmic energy.
