Pop some peppermint. Research indicates that mint can make you feel more awake by stimulating facial nerves. Not in the mood for gum or mint candy? Have a slice of an orange or a glass of lemonade -- citrus products are believed to have some of those same energy-boosting properties, says Alan Hirsch, M.D., the neurological director of the Smell & Taste Treatment and Research Foundation, in Chicago.
Give yourself a break. Even if it's only for a few minutes, kick back with a good book, write in a journal, or call a friend. If you have more time: Invite a neighbor over for a leisurely lunch or grab a movie.
