Our brains need the proper recharging and this can only be experience with proper sleep. Apparently we all have our ups and downs and the stress from everyday thinking and decision making will take its toll on the human brain.

Hence, it is not surprising to note why in the initial stages of sleep that energy levels increase in the brain region found to be active during the waking hours. These results suggest that a surge of cellular energy may replenish brain processes needed to function normally while awake.

Dopamine

While focusing on sleep deprivation as a growing concern, there are people who are still at it when it comes to needing to be awake for most of the time, mainly for work and personal reasons to which certain drugs and means are being taken to aid them. Dopamine, a fell-good brain chemical helps keep sleep-deprived people awake. But the question here is on whether it is helpful.

Most people are trying to fend off these drugs that keep us awake. Many are likewise looking for cures to cure their sleep deprivation and sleep disorders. But while these things are a given, it would be wise to analyze how Dopamine helps and for what purpose.

For sure there will be after-effects and consequences. But for people who have to be on the go, stay awake most of the time, Dopamine may be an option but for how long?

Sleep deprivation increased dopamine in the striatum, a part of the brain that registers motivation and reward. Dopamine also went up in the thalamus, a brain region that helps control alertness, when the volunteers were sleep-deprived. Increases in the brain chemical kept the volunteers awake, but those same increases also correlated with the volunteers reporting that they felt tired.
