One of the best ways in which the trend and the practice of spirituality is helping people is that it is making them take time out for meditation. And something as simple as deep breathing and chanting or humming, can relax the body, clear the mind, reduce the stress, and also improve behaviour and sleep patterns.
When people get into spirituality, even if it is just for a trend, they are still calming themselves down for 5 minutes everyday, which has long-term benefits.
