Yoga is known for its benefits for adults: emotional and physical balance, anti-stress, flexibility, sleep, etc.… However, it also has benefits for children as well.
It can be particularly useful for those who suffer from anxiety or have an attention deficit disorder. Over the course of the sessions, they will learn to discover their body and apprehend it in a more harmonious way. This should boost their self-confidence.
These techniques do not require any special physical skills, and they can be taught and practiced from a young age, even in kindergarten, making sure that the sessions are above all fun. Thus, the postures helping to breathe better or to develop a sense of balance could be named after nature and animals (tree posture, dog posture, etc.).
It is important that the sessions do not last too long, around 10 to 15 minutes. Otherwise, the child is likely to get bored. And of course, you should never force a child to do yoga, it would be totally counterproductive.
