Smelling the Roses Relieves Stress
A novel technique to relieve stress is an age old naturopathic remedy. New research demonstrates the scent of lemon, mango, lavender, or other fragrant plants are beneficial for stress reduction.
Scientists in Japan report the first scientific evidence that inhaling certain fragrances alters gene activity and blood chemistry in ways that can reduce stress levels.
Their study appears in ACS’ Journal of Agricultural and Food Chemistry, a bi-weekly publication.
In the new study, researchers sought to determine the physiological reason for why people have inhaled the scent of certain plants since ancient times to help reduce stress, fight inflammation and depression, and induce sleep.
Aromatherapy, the use of fragrant plant oils to improve mood and health, has become a popular form of alternative medicine today. And linalool is one of the most widely used substances to soothe away emotional stress.
Until now, however, linalool’s exact effects on the body have been a deep mystery.
The scientists exposed lab rats to stressful conditions while inhaling and not inhaling linalool. Linalool returned stress-elevated levels of neutrophils and lymphocytes — key parts of the immune system — to near-normal levels.
Inhaling linalool also reduced the activity of more than 100 genes that go into overdrive in stressful situations. The findings could form the basis of new blood tests for identifying fragrances that can soothe stress, the researchers say.
