Cognitive fatigue is the decline in your mental performance and focus that is caused by sustained, demanding mental activity.
Cognitive fatigue is also described as "brain fog" or even being mentally fried.
The cognitive fatigue is basically the brain's biological signal that the brain is overloaded and requires a break to recharge.
The cognitive fatigue involves several key components, which include.
Prolong mental effort causing an accumulation of your neurotransmitter glutamate in your brain's prefrontal cortex, which is a buildup that reduces cognitive control and limits your ability to process information efficiently.
Indicators and common symptoms of cognitive fatigue include slower processing speeds, difficulty concentrating, forgetfulness and having a reduced ability to regulate emotions, which leads to increased irritability.
The cognitive fatigue can cause tasks that take minutes to take hours, which can result in a dramatic dip in your overall productivity.
When you're experiencing cognitive fatigue, you may notice you have brain fog, task paralysis, impulsive choices and the cognitive fatigue may also be accompanied by unexplained headaches, stomach issues, and disrupted sleep schedules.
A tired brain, often also seeks immediate, easy rewards instead of tackling delayed and longer term goals.
Task paralysis in cognitive fatigue involves procrastination or struggling to complete even simple decisions because everything you're trying to do feels overwhelming.
And the brain fog, can result in rerunning the same sentence, feeling mentally "spent" and zoning out in conversations or tasks.
To manage and overcome cognitive fatigue, take strategic breaks and use restorative practices and short relaxation techniques.
If you're able to, get up and walk around and go outside if possible as going outside can also help clear your mind and make you more focused.
And ensure that you're getting plenty of sleep as quality sleep is essential for clearing your brain toxins and maintaining memory and attention.
And limit multitasking and break large, daunting tasks into smaller and more manageable chunks.
