Paragraph 2
In the four-year study,
studied 3,568 children aged between 9 and 15 at 31
in London. They examined the
between the natural environment and thinking skills, mental health and
well-being. The researchers calculated how going to woodland and parks, and "blue
" like rivers, lakes and the sea, affected children's health. They asked children to take
-based tests. The children who visited woodland every day scored higher on the
. They also had a 17 per cent lower risk of emotional and
problems. Mr Maes recommended all children experience "forest bathing" or "forest
". This is "being immersed in the
, sounds and smells of a forest".
