Sitting uncomfortably puts a strain on the neck and spine, especially when reading, and can contribute towards multiple long-term physical effects on the body and can also affect mental health in both adults and children. Behaviour can be massively affected by the space in which we learn and for children, this is fundamental to their development and their ability to absorb and retain information.
