Yes. Yoga has a very positive impact on the quality of the sleep. The combination of breathing exercises, postures and relaxation produce a profound soothing effect on the nervous system and the entire organism. And one can already feel a clear improvement of the sleep experience after only a few sessions. Moreover, yoga postures also have an effect on the endocrine system. For example, inverted postures stimulate and balance the pituitary and pineal glands, which are responsible for the wake and sleep state cycles in the body. So a regular practice (at least twice a week) allows to progressively operate a full re-balancing of the organism and its various functions, including sleep.
