Boosts energy + soothes sinuses

An energizing Rx for the season’s shorter days and drearier skies: six slow, deep sniffs of peppermint essential oil. British scientists say this sweet scent kick-starts the release of energizing beta brain waves to heighten alertness and stamina by 55%. Bonus: If seasonal allergies hit, inhaling peppermint-scented steam can open swollen sinuses and improve drainage so you breathe easy in 10 minutes. Just put 5 drops of oil on a washcloth and leave it on the shower floor (out of the water stream) so the oils can infuse the air as you wash.
