Why most people wake up tired in the morning

Hello dear reader you might realize that most of the mornings you might wake up feeling very tired even after sleeping for long hours or in a very comfortable mattress and a mountain of blankets above you    . Here are the reason why  you might wake up tired.  Sleeping with a hard pillow; which may cause your neck and head to be higher than the rest of the body ,this makes the blood flow to the head  a little less and thus a little less blood flows into the brain making.Which also makes air supply less  and you know air supply is very important to the brain so ask no more . Buy yourself a comfy pillow or put other pillows bellow your back and under your knees .
