These Scents Will Help Wake You Up Instantly

Oranges are not only good for us to eat, but their properties are also considered energizing and calming. The scent of orange essential oil helps reduce stress, which allows you better to focus on the task at hand.

Even if you don't live like the koalas in Australia, you can reap the energizing benefits of eucalyptus leaves from their essential oils. While it's long been linked to treating aches and pains, eucalyptus oil also has energizing benefits. It has been shown that brain wave activity increases when people breathe in eucalyptus oil, alleviating both mental and physical fatigue.

Like eucalyptus, rosemary can have positive effects on the brain, which can help during those times you're feeling fatigued. Studies have shown that smelling rosemary helps with memory and focus.

With similar properties to lemons and oranges, the smell of grapefruit can leave you feeling refreshed and energized and can also combat stress and depression. When rubbed onto the skin, it's even been shown to help combat muscle fatigue.
