Studies have shown that if you get an alarm clock that suddenly wakes you up your stress hormone levels can be up to 15% higher for the rest of the day. Sleeping with mild white noise can reduce stress hormones for the following day by 8%. (ever wonder why you sleep better when its raining? now you do) and sleeping with some source of light in the room can increase your following days average stress levels as high as 35%. So please, turn off those computers, turn off the nightlight’s, put the radio on almost mute and sleep tight.
