I meditate for about 30 minutes each night before sleeping and it does make up in multiples in lack of sleep. Without any scientific evidence but at least I feel more rested the next day. 7 hours of sleep with a full time job, a startup, kids and exercise? Is this even possible! One great life-hack we have is to sleep with the windows open and with thinner sheets. We both feel more refreshed the next day. And apart from the alarm clock, there are no devices :)
