If you are suffering from a case of afternoon slumps then eat or smell peppermint.
It is known to wake up and help decrease fatigue.
In fact research at the University of Northumbria found that in a test involving word recall, peppermint-gum chewer’s scores were up to 36% higher than non-chewers.
They also say that Siberian Ginseng which has been around for centuries is known for its anti-fatigue qualities. It acts like a tonic, which can then increase the body’s vital energy.
