Yet why do you really feel much more dazed on some days and out others? When your mind is asleep, it changes in between deep and light phases. If your alarm goes off throughout a much deeper phase of rest, it takes much longer for all the components of your mind to get up. You can make use of technology to track what stage of sleep you’re in and after that wake you throughout a light phase, so you get up really feeling much more freshened.
