“I feel more refreshed,” he said. “It's easier to wake up.”
I agree. I have enjoyed waking up in a more peaceful way even after going to bed too late the night before. It is better than being jarred awake by an alarm set for an exact time.
Krishna noted that we all follow a circadian sleep wave cycle, with five stages of sleep alternating between heavy and light periods.
The app tracks those stages and offers a graph each morning to show them to you. The graphs are interesting, and I can see when my sleep was the deepest. The app also tracks how long you've slept.
Although I'm not sure how I can use the details about my widely varying sleep patterns, it shows how little sleep I am getting. I already knew that, but using the app, I hope to start working with my body's clock instead of against it.
