Relax, give your mind little breaks
Thoughts have been swirling around like a sandstorm about work, things I've been reading, household tasks, finances, concerns about people, a yard that needs mowing, loose ends, projects, etc. etc. The other day I told my wife: "I'm thinking about too many things." Know the feeling?
By "head" I mean the cognitive aspects of experience such as planning, analyzing, obsessing, considering, worrying, making little speeches inside, going back over situations or conversations, and trying to figure things out. "Weary" means being fatigued due to continued exertion or endurance, sometimes also with a sense of being dismayed, even depressed; its roots as a word have to do with the effects of a long journey. Basically, your tank is running low.
When your thought processes are tired, it doesn't feel good. You're not relaxed, and probably stressed, which will gradually wear down your body and mood. You're more likely to make a mistake or a bad decision: studies show that experts have less brain activity than novices when performing tasks; their thoughts are not darting about in unproductive directions. When the mind is ruminating away like the proverbial hamster on a treadmill, the emotional content is usually negative - hassles, threats, issues, problems, and conflicts - and that's not good for you. Nor is it good for others for you to be preoccupied, tense, or simply fried.
On the other hand, when you rest that busy mind, you stop wearing it out plus you start refueling and repairing it. The roots of the word "rest" come from places to take a break on a journey; it's natural and necessary to rest when you're weary. How? Routinely check in with yourself and ask: What am I thinking about? Is this productive? Do I want to keep thinking about this?
Give your mind little breaks. Look up into the corner of the room. Exhale; this engages the calming and restorative parasympathetic wing of the nervous system to slow your heartrate; the longer the exhalation, the more parasympathetic activation. Bring awareness into the body, whether it's sensing the breath or paying attention to the movements of walking or reaching for a cup. Set aside a dozen seconds to follow a few breaths.
Step back and take a bird's-eye view of wherever you are, as if you were looking down on it from a few hundred feet above. Try to see yourself in a more impersonal way.
Above all, recognize that, if you're like me and I think most people, so much of what we twirl around with in the mind is, frankly, a waste of time. It doesn't solve a problem, prevent a bad thing from happening, or bring us to peace with others. And it's deeply unnatural.
