What do you mean long-term stress?
Well, these researchers at the Max Planck Institute for Human Cognitive and Brain Sciences measured cortisol levels over six months through hair analysis
Through hair analysis?
Yes, your hair provides a great record of what was happening in your body when it grows. This is much more accurate than using a subjective questionnaire and much less invasive and easier to carry out than collecting multiple saliva samples because stress can vary throughout the day and in short-term bursts.
What is the importance of cortisol?
For those who don’t know cortisol is considered the stress hormone and measuring this is very good way to biologically measure stress. It has multiple negative impacts on multiple processes in the body (including altered brain growth) at elevated and chronically elevated levels.
And what were the results?
Well, they showed that stress reduced moderately for the first three months and then accelerated after three months. With an average of 25% reduced levels.
So you need to stick at it?
This suggests this is the case. The more you do it, the greater the benefits.
