Sleep specialist determines the key factor in improved sleep. Neurologist and sleep medicine specialist W. Christ Winter, MD, has discovered what it takes to improve your sleep routine. All it takes is setting your alarm for the exact same time daily, regardless of what time you go to sleep the night before. Sticking to a predictable wake-up schedule can actually train your brain to shut down with some level of consistency. He also adds, the concept of a good or bad wake up time isn’t real. If you function better as a night owl or you are more efficient as an early riser, he recommends sticking to your routine instead of trying to fit into a specific mold.
