Lets share different benifits of reading. Here goes the first one:
When we read, we are still. We get comfortable. Most people sit while reading. Our bodies do not carry any special movements, they rest. The breathing slows down. We calm down. We imagine ourselves the worlds or situations described by words in the book. While reading we cannot think of other tasks or worries. Because of all this reasons reading does reduce stress.
I biggest benefit according to me is the mental stimulation. Studies have shown that regular mental stimulation slows the progress of Alzheimer’s and Dementia. Solve a crossword daily, or read a book. Works the same.
