Accomplishing a task gives us satisfaction because our brain releases dopamine, which is the reward hormone. Of course, our brain loves this hormone which encourages people who multitask to keep doing many tasks and to maintain the habit of switching between tasks in order to achieve more and feel rewarded. This can be dangerous because it could make us feel like we have accomplished a lot, while what we’ve done is nothing that requires a lot of critical thinking.

For a multitasker, organizing thoughts and keeping irrelevant information away is more difficult which reduces to quality and efficiency of their work. This could also affect the IQ of an individual leading it to drop. It could as well make them more stressed due to the increase of cortisol (the stress hormone) because making our brain continually shift from one thing to another, tires it and makes it stressed out.

Men who multitask can experience a drop of IQ of up to 15 points leading them to become an alternative to an 8-year-old kid.

Some recent research has shown that there is a possibility that the damages caused by multitasking, could be permanent and lasting on humans' brains. Another study, done by the University of Sussex in the UK used MRI scanning on the brains of people who were using multiple devices at one time such as watching TV and texting at the same time. The results that the MRI gave, showed that these individuals showed less brain density in a part of the brain named the anterior cingulate cortex. This part or area is responsible for emotional control and empathy. While these results are not quite detailed to tell if multitasking is due to existing brain damages, or the results are due to multitasking, it is clear that multitasking has negative effects on the person’s health. As a conclusion, multitasking is not something you need to be proud of in front of your friends. Instead, work on achieving each task very well before you move on to the other so you can enjoy the reward of dopamine.
