You can sleep effectively.
Prepare for sleep by creating a mental refuge, a buffer between the problems of the day past and the challenges of the morrow. At the end of your day, imagine huge steel doors slamming shut to signify the end of your labours, then make a real effort to ‘let it all go’. This also includes letting those little screens (phones and Ipads) go 1 hr before you plan to sleep.
When you do this, your body will rest more efficiently and you may find yourself sleeping through the night and waking fully rested and ready for action, earlier than you normally would.
Don’t focus on sleeping duration; focus on sleeping well.
