Lavender

Lavender is often thought of when it comes to promoting relaxation (remember what we said about putting some on your pillowcase at bedtime?). But a Japanese study actually discovered that, when inhaled during a work break, this essential oil can improve your concentration once you get back to the tasks at hand. The research specifically focused on students on their recess (some were exposed to lavender oil; others to jasmine essential oil, which didn’t have any effect).

Of note: The study points to the fact that lavender’s ability to lessen stimulation and decrease stress was likely helpful in allowing the students to take an appropriate break and refresh themselves for their next round of work.
