Most of us like to multitask. Doing multiple things at once is almost an essential skill to succeed in life.

It turns out, however, that multitasking may do more harm than good, especially when it comes to simultaneously exerting ourselves mentally and physically.

It sounds crazy, because it’s not like we can stop thinking, but lo and behold, there’s magic at work behind these skin and bone layers that affect us in ways that we can’t see.

Let’s say you go on a five mile run, chances are you’ll come back strong on a second wind, but then feel like crashing immediately afterwards. The same goes for having a long stressful day at work. After the mental circus with your boss and coworkers, you’ll probably be craving a mental recess.

Now picture getting on an elliptical while reading through a work report. Mixing these two significantly increases the level of fatigue on your body by engaging in tasks that are equally mentally and physically taxing.



According to Science Daily, when we perform daily activities, a number of factors are at work that contribute to us being tired.

When you put your brain to use:

  • There’s activation of the prefrontal cortex, which can lead to stress or greater fatigue.
  • There’s lower blood oxygen levels in the prefrontal cortex.
  • Highly cognitive tasks require more brain function, which in turn, may fatigue the body more.

The body goes through:

  • Muscle fatigue
  • Energy system depletion
  • The limits of physical endurance




So much is going on, that it almost makes you want to sit in a three-by-three square feet room and stare at a wall just to conserve some energy. But you’ll be glad to hear that there’s a simple solution.


How To Be Less Tired:

The key to decreasing this cumulative fatigue is mindfulness. By not being consumed by the ongoings of every single part of life at the same time, you can save brain energy while using your body. Focus on being in the moment, at that particular moment for every moment.

Sharp mental function is an important part of living a bountiful 20something life. Try to disconnect your physical and mental activities and focus only on the moment at hand.
