Brain drain, mental exhaustion, brain fried, or mental fatigue- no matter what you call, often we all face this. This is quite prevalent in many of us. Eventually, after spending the whole day at work we tend to feel mentally exhausted.
But is this mental tiredness similar to that experienced by our muscles? Or there is a difference between the two? Well, mighty science has got an answer to your queries.
Does Your Brain gets exhausted just like Muscles in your body?
The brain is an organ, not a muscle. But it does need energy to work. And this energy is obtained from glucose. On reaching brain cells the glucose transforms into adenosine triphosphate (ATP). ATP is a complex chemical compound responsible for storing and transferring energy to brain cells.
As per researches, ATP is the compound responsible for causing brain drain. When your brain is exposed to intensive work it leads to depletion of glucose, thereby making you feel exhausted. This lowering of glucose level increases ATP which further lowers down the production of dopamine, a chemical that helps human beings stay motivated. When your brain gets depleted of dopamine you tend to feel lethargic and unmotivated. Thus, even if your brain is not muscle it is vulnerable to feel exhausted and tired after thinking too much.
However, if you are involved in a repeated task your brain is likely to consume less energy. While on the other hand, if you undertake a new task that requires you to invest substantial energy in every decision making then you are likely to face mental fatigue.
Draining all available glucose in the brain leads to mental tiredness. But just having supplements of glucose won’t help. If you want to stay all charged up even during complex tasks follow healthy practices. Get enough sleep, eat a healthy diet, and undertake some recreational activities.
