Sunshine and heat are natural mood-elevators, according to a recent article in The New York Times (“Dr. Google Will See You Now”, Seth Stephens-Davidowitz, Sunday, August 11, 2013). So unless you live in Southern California, Florida, or equally radiant zones, prepare for gloom as summer ends.

Not that we’re downers. On a positive note, essential oils are instant mood-boosters, especially when diffused into the warm water of your shower. Health practitioners from across all disciplines agree: aromatherapy eases depression.

Back to the weather. Dr. Davidowitz wrote his story based on “big data”, scanning Google searches about depression. He has yet to explore the idea that aromatherapy eases depression–he simply focused on the concentration of searches relating to depression. His studies reveal, for instance, that people seem really, really depressed in April, and happiest in August. Is it a coincidence that in much of the US, April is the last gasp of winter before the days grow long and warm? No coincidence at all, says Dr. D. Is it a coincidence that, based on the data, the happiest day of the year may be August 11, when ¬†North America has been drenched in sunshine for months? Again, no coincidence.

Of course, low energy and blue moods may find us at any time, regardless of where we are on the calendar. So the realization that aromatherapy eases depression is a year-round relief. The bright, astringent notes of the essential oils of Citrus– Sweet Orange, Mandarin, Lime, Lemon, Bergamot– are especially popular examples of how aromatherapy eases depression. Why? One element may be that these sparkling aromatics remind us of the tropics, and sunny vacations (flash back to Dustin Hoffman as Ratzo Rizzo in “Midnight Cowboy”, waxing rhapsodic about Florida and coconut milk).

There’s also growing neurological evidence that aromatherapy eases depression in the case of the essential oils of Citrus fruit. The molecules in these tangy oils may affect how the brain regulates mood-related chemicals including dopamine and serotonin– which also are impacted by sunlight.

No, not all light is created equal, by the way. Sitting by a desk-lamp in an otherwise darkened house in the middle of February in Minot is not the same, neurologically, as walking on a beach in Costa Rica. If you look out the window and see icicles forming and snow falling, remember that aromatherapy eases depression– and break out the Essio aromatherapy pod of your choice. One click, and you’re showering in a diffused blend of 100% USDA certified essential oils, Nature’s antidepressants.

The specific correlation between temperature and depression– yes, people who live in cold places do more Google searches involving the word “depression” than people in warm places– is so clear that Dr. Davidoff, a Harvard economics Ph.D, suggests that these people simply pack their bags and head south if they know what’s good for them.

Anti-depressant drugs get mixed reviews from this researcher. Dr. Davidoff states: ¬†“To judge from the Google numbers, a Chicago-to-Honolulu move would be at least twice as effective as medication for your cold-months mood.”

Not hating on the Windy City, mind you. But if icicles are in your winter forecast, remember that aromatherapy eases depression, and stock up on Essio aromatherapy for the shower in time for the first frost.
