When a toddler becomes tired and low on energy it starts to whine and throw tantrums, all the normal things it usually takes in its stride suddenly seeming insurmountable problems which become very upsetting. If the child were to have a nap or to eat something, then generally it feels refreshed, re-invigorated and happy again, able to continue on its day in its usual carefree manner.
The same can be said about adults, to a lesser degree. When we are tired or hungry or when our blood sugar levels drop, we can become irritable and small issues can become overwhelming problems that we find difficult to face.
If we, or the child, were to eat something, or rest, nourish our bodies in some way, then we are re-energised.
This is an accepted fact – our bodies need rest and nourishment to perform.
It is the same for the mind.
Generally we do not take as much notice of the mind as of our bodies, as the signs are much subtler, but they are intrinsically linked. If we have a good nights sleep, not only does it refresh the body but also the mind.
If we have a stressful job, we like to go home after work and watch TV or listen to the radio, perhaps meet with friends or book a holiday. This is all very well, but it doesn’t give the mind much opportunity to switch off.

If we sit, without distraction, and let our thoughts melt away, we can give our minds that much needed rest time and can feel as refreshed and energised as we would after a sleep. Peace of mind is an underestimated, valuable necessity.
