To fall back asleep fast - try this:
Think about something you love. I mean, really think about it, to the point you immerse yourself in the visualization. That advice comes from sleep specialist Dr. Christopher Winter. He’s a sleep coach for professional baseball players - and tells them to visualize throwing 30 perfect pitches. Smell the grass, feel the seams on the ball, feel the sun on your face, hear the crowd - picture everything. He says his patients usually can't make it past 5 pitches before they’re back asleep. Dr. Winter says visualization reduces anxiety and lets our brain's sleep mechanism take over. And according to the Walter Reed National Military Medical Center, 65% of the hospital patients who used that visualization technique took less time to fall asleep, experienced significant improvement in sleep quality, and felt less fatigued the next day.
