But what is actually happening in the body to make us “FEEL” this way?
1. Blood pressure lowers.
2. Heart rate slows down.
3. Breathing slows down.
4. Muscles and bones have an opportunity to relax.
5. Gravitational forces are more equally distributed.
6. A mental sense of “It is ok to relax”.
“Lying down gives the body a chance to recuperate from a busy stressful day. A fully supportive horizontal position provides a necessary reprieve from gravitational forces so that all physiological systems, including musculoskeletal and cardiovascular activity, metabolic and heart rate, and circulation, can slow down. When this occurs, the body is able to replenish the vital resources that have been naturally depleted throughout the day.” (Dr. Joseph Weisberg, Heidi Shink)
So, it's better to have a minute time to lie down at work, it can increase your productivity after doing it. Just lie down, if you don't have the time to nap...
