A tool some people find helpful for feeling more calm and relaxed is something called Yin Yoga. If you haven't tried it, the first thing you'll notice is that it's quite different from most other forms of yoga. For one thing, the poses are about letting your muscles relax rather than tighten. It's slow, it's not about strength, and it's not going to give you a "work out." It will, however, help you feel more peaceful, cozy, and at ease. Try incorporating it into your pre-bedtime routine to set yourself up for a great night’s sleep.
