Depression is one of the most common mental health issues in North America.  Lifetime prevalence of depression varies widely, from only 3% in Japan to a staggering 17% in the US!!! In most other countries the number of people who would suffer from depression during their lives falls within an 8–12% range.

People are most likely to suffer their first depressive episode between the ages of 30 and 40, and there seems to be a second, smaller peak of occurrence between ages 50 and 60. Why is the provenance of depression in the U.S. so high and seemingly increasing?  Known risk factors for depression are alcohol and substance abuse, sleep disturbance, bereavement, medical conditions, family history, and being female (yes, woman are most likely to have a depressive episode in their life compared to men!).


It has also been suggested that pollution and toxic chemicals that we are exposed to can influence depression. Only a few studies have evaluated the association between air pollution and depressive symptoms in humans but they have demonstrated that toxic chemical may affect mood. In Canada, researchers reported short-term effects of air pollution on emergency department visits because of depression and suicide attempts.

Another study found that increased pollutants in the air were significantly associated with depressive symptoms measured repeatedly among an elderly population in Korea. Other studies have suggested a chemical that was found in plastics know as PCB as another risk factor for depression. PCBs are manufactured chemicals that were produced for nearly 50 years in the United States before they were banned in 1977. PCBs were banned because of their potential carcinogenicity, however, some of their effects may still persist in the environment.

Chemicals used in cleaning supplies, air fresheners and perfumes have been linked to depression, as well as other major health risks. A study led by Alexandra Farrow of Brunel University in the United Kingdom linked air fresheners in the home to higher incidence of diarrhea and earaches in infants and headaches and depression in their mothers. Not to mention common chemicals found in cleaning products and air fresheners have also been linked to:

  • asthma
  • allergies
  • reproductive abnormalities
  • cancer

Personally, we don’t use commercial household cleaners or air fresheners to avoid these potential risks! We simply make our own cleaners, and add essential oils for added anti-bacterial action and for freshening the air. Even better, certain essential oils are associated with boosting the mood.

Simple and affordable recipes for cleaning solutions

All Purpose cleaner

Mix equal parts white vinegar and water.  Add tea tree oil or lavender oil to the mixture, adjust amount for desired smell. You can make this ahead of time and bottle it, or just make as needed when cleaning.


Tile Grout Cleaner

Mix 1 part water and 3 parts baking soda mixed into a paste. Apply to grouty area and then scrub with a scrub brush or tooth brush and remove with a warm cloth.


Mix equal parts lemon juice with sea salt and scrub. Baking soda can also work well.

Toilet Cleaner


Just add white vinegar to toilet!! …and maybe a little essential oil for freshness. Scrub as usual with toilet bowl cleaner.

Air Freshener

Essential oils sprinkled around the house smell great, or an essential oil diffuser is also a great option for freshening the air.
