Before marriage, I slept with no sound. My wife introduced me to white noise, as she couldn’t sleep without it. Many years later I find silence hinders my sleep.
And I’m a firm believer that quality sleep is so important in life. It aids physical, mental and emotional health. Without consistently good sleep (7-9 hours), I’m moody, tired and sluggish throughout the day, and I lack focus.
So sleep, very important. And if you workout a lot, you need sleep for recovery. And if you drop into REM sleep, yo’re burning calories like an extra workout. Double benefit!
