If you are planning a road trip, try using essential oils to keep you going. Of course, if you feel drowsy, pull over to take a nap. However, if you just feel yourself going on auto pilot, try diffusing or rolling on peppermint, sage lavender, basil, lemon, or rosemary to help you stay alert.
To Diffuse: Just add 1–3 drops total of any of the above oils to a car diffuser or a jewelry diffuser, and let the AC circulate the aroma.
To Roll On: Dilute 1 drop of essential oil with 4–10 drops of carrier oil in a roll-on bottle. For a 5 ml roll-on, add 10–20 drops of oil, and then fill the rest with a carrier oil. For a 10 ml roll-on, add 20–40 drops essential oil, and fill the rest with a carrier oil. You can even use a tiny roll-on bottle that fits neatly in a key chain case. Some common carrier oils include fractionated coconut oil, sweet almond oil, and jojoba oil. To use your roll-on: Simply roll the oil onto the wrists and neck.
