@mindbodygreen: What do you do when waking up in the middle of the night? Sleep expert, Dr. Wendy Troxel, wants you to try this. If you’ve been tossing and turning for ~20–30 minutes, don’t stay in bed getting more frustrated. Get up. Go to another room. Do something low-stress but mentally engaging (like reading or folding laundry). #mindbodygreen #sleeptips
