A study published in the journal Frontiers in Psychology revealed that just a 20 minute nature experience was enough to significantly reduce cortisol levels, a stress hormone, in human subjects.
"We know that spending time in nature reduces stress, but until now it was unclear how much is enough, how often to do it, or even what kind of nature experience will benefit us," said lead author MaryCarol Hunter. Healthcare practitioners can use this finding to prescribe 'nature pills' to have a real measurable effect, according to researchers from the University of Michigan. Sitting in the nature has the same effect. ” You don’t have to travel to the wildlands. Getting out of an office block and sitting next to a tree can be enough”, MaryCarol Hunter added.
Spending time connected to nature has previously been suggested as a low-cost way of combating health issues including high-blood pressure and mental health problems. Cortisol is produced in humans by the zona fasciculata of the adrenal cortex within the adrenal gland. It is released in response to stress and low blood-glucose concentration.
