In publications, it is explained through numerous intertwined scientific terms. Our body,
Our systems, even each of our cells, are quite complex. All our organs, our hormones,
our receptors, the chemicals we secrete… they work in harmony and interaction with each other.
Therefore, passing an essential oil through these pathways is a complex and intertwined process.
Today, by simplifying as much as possible what happens to you after inhaling an essential oil and
I will try to explain all the links of the chain. (Resources for more detailed information)

In mammals, the HPA axis (hypothalamic-pituitary-adrenal axis) is the hypothalamus of the brain.

The secretion of the hormone also triggers the release of cortisol (glucocorticoids) in humans.

The central nervous system consists of sympathetic and parasympathetic nerves. Activation of stressors
Another element that it does is the response of the sympathetic nervous system. As a result of this reaction, respectively, adrenaline
