To inculcate, values, we also INVOLVE our children in various activities like growing vegetables, tidying up the classroom, replacing plates in the crates after lunch, sharing with others, conducting assemblies and so on. Our children are not confined to classrooms. There is learning which happens during the field trips, nature walks (inside the campus), natural experiential learning with classes under the tree etc. The aim is always to help children to face their life.
Understanding the science of our body mechanism can help us to mould our children better. The reason for introducing pranayama for our children is to help improve their brain functioning. If your right nostril is dominant, the left side of your brain will be dominant and vice-versa. The right nostril is directly related to the sympathetic part of the brain, the fight or flight mechanism. On the other side, the left nostril is directly related with the parasympathetic part of the brain, the rest and repair mechanism.
According to this, breathing through the right nostril will make you tap into a more energetic state of mind and at the same time results in an unbalanced state of mind by creating more stress and lowering our immunologic defences. At the same time, breathing through the left nostril will make you relax and calm down.
