Days there are when you have done nothing physically tiring-no heavy work, no great concentration, no long days-and at the end of the day you are completely exhausted. Not only weary, but weary as it were of the mind, and which we know to be unrenewed by rest. This emotion can be puzzling. What is the point of becoming so tired when you hardly did anything? The solution does not lie in what you have been doing physically, but what your mind has been doing all along in the background.
Mental fatigue is not necessarily a result of physical
work. Indeed, certain processes that are most draining are not visible,
automatic, and constant. Overthinking is one of the largest contributors. When
you are sitting still your mind may be replaying the past, worrying about what
may happen tomorrow, or analyzing a situation that has not yet taken place.
This endless cycle of thinking is an energy-consumer. Your brain cannot tell
easily the difference between what you do really and what you imagine and imagine-
both need processing power. So as long as what you see is resting your mind is
always active, and that continuous activity gradually exhausts your mental
resources.
The other significant contributor is decision fatigue.
Every day, even minor decisions count up, what to eat, what to wear, what to
watch, whether to answer a message now or later. These judgments may appear to
be insignificant, yet every one of them consumes a bit of mental power. When
the day to day routines you follow are full of constant micro-decision-making,
your brain becomes overloaded, although you may not have been consciously aware
of the burden. This mental effort can be quite surprising in its exhaustion at
the end of the day.
Another drain, which is not visible, is emotional load.
Wearing emotional weight does not require one to be actively engaged in dealing
with a crisis. Other times, it is not overt, it may be unresolved stress, the
worry that is not spoken, or the need to perform up to expectation. You could
be considering your future, comparing yourself with others, or simply getting
rid of self-doubt. Although you may not be displaying these emotions
externally, they are still going through your mind. It takes a lot of effort to
hold the emotions inside and as time goes on, this effort accumulates and the
result is mental fatigue.
Digital overstimulation is also an important factor. In
our modern reality, your brain is constantly overwhelmed with information:
social media updates, notifications, news, videos, and endless scrolling. You
may think that you are relaxing, but in the process, your brain is actually
working hard to process all this input. Every piece of content requires
attention, interpretation and in some cases even emotional response. Such
continuous change of the focus does not allow your mind to relax. Rather than
being recharged, it remains in a low-level state of activity which slowly wears
it down.
Absence of psychological barriers may compound the
situation. When there is no obvious boundary between the work time, the rest
time, and personal time, your brain is not aware of when to turn off. You may
be physically at rest but in the mind you are still on. Responsibility, task,
or unfinished work thoughts still continue to play in the background. Your mind
is in a state of alertness, which in the long run contributes to burnout, even
when you are not actually working.
It also depends on the quality of sleep and not quantity.
You may be having right amount of sleep but when your mind is not at peace the
sleep may not be restful. Deep, good sleep can be avoided by stress,
overthinking, or spending too much time on the screen before bed. This means
that your brain is not entirely rejuvenated and you end up even feeling a bit
exhausted upon waking up. It is a low level fatigue that can accumulate
throughout the day and it seems that you are feeling exhausted but not necessarily
because of a reason.
Another influence is the influence of repressed action.
Mental exhaustion is sometimes done by things that you did not do. Things you
have been avoiding, things you have yet to achieve, or decisions you have been
putting off, create a sort of internal tension. These incomplete loops keep
replaying itself in your mind, and it uses energy to remind you that something
is unfinished. This forms a back ground pressure that wears you down in the
long run.
Lack of meaningful engagement is another causative factor
that is neglected. Not doing anything is not necessarily a restful thing to do.
When your day is not full of purpose or stimulation that feels like a good
life, then your mind is apt to grow stagnant and exhausted. Passive habits,
such as scrolling without thinking or watching TV without actually engaging in
it, do not provide the sort of mental stimulation that leaves you feeling
refreshed. Rather, they mostly leave you feeling emptier and more exhausted.
What of it, then, Can you do? It does not mean that you
should do less, but rather be more conscious of your mental energy. Begin by
sensitizing yourself on the patterns of thinking. When you realize that you are
overthinking, then you need to redirect your mind but not allow the process to
spiral out of control. By developing routines to limit the number of
unnecessary decisions, it is also possible to conserve mental energy. To
illustrate, a regular routine or making decisions in the morning that is simpler
to make than the ones we make in the morning means that the cognitive load is
lessened.
It is also important to take a break as an input of
digital information. By giving your brain some time to relax, not being on
screens, notifications, and constant stimuli allow your brain to reboot and
restore its functions. Even a couple of hours of silence or even the most basic
mind-body activities, such as walking, can assist in restoring your mind.
Addressing emotional weight is also key. Rather than stifling the feelings,
learn to process them either through writing, talking or just by recognizing them.
A significant difference could be made by the improvement
of sleep quality. Establishing a relaxing nighttime routine, limiting your
screen time before going to sleep and letting your mind relax can help you wake
up feeling more refreshed. And, perhaps best of all, attempt to close open
loops. Solving minor challenges or decisions you have been putting off can make
mental space and alleviate that background tension.
Having experienced mental fatigue when you have not done
anything is not a symptom of laziness or weakness. It is an indicator that your
mind has been busy in a manner that you might not have realized. When you know
where that energy is going then you can start to keep better track of it.
Mental energy is no more real and limited than physical energy--and learning
how to conserve it can transform the way you feel on a daily basis.
