KEEP CALM AND WATCH A TREE
Do YoU feel calmer gazing at all that greenery? Possibly that’s because your heart rate is slowing. Studies have shown that spending time in nature can lower heart rate and also raise activity in the parasympathetic nervous system which calms the body — and you get similar effects looking at pictures of plants. In a study that was published in 2012, researchers at VU University in Amsterdam found that people in hospital waiting rooms with pictures of nature on the walls felt less anxious than those in rooms that were bare.
Researchers in South Korea’s Chungnam National University have also found that looking out of windows and seeing trees improves mental health.
one theory is that the greenness causes a reaction in the brain that lowers activity in areas controlling fear, such as the amygdala.
This allows the system that calms us to take over.
