Doctor Explains How Water Can Wake Up Your Brain Better Than Caffeine
Anyone who thinks coffee is the only drink that can give a short-term boost is wrong. Trust me: water is also a great option for anyone who wants or needs a boost. stay awake.
Second Fernando Gomesneurosurgeon, neuroscientist and full professor at the USP School of Medicine, several reasons related to hydration and brain function cause coffee to lose water when you intend to wake up.
Water vs Coffee to Stay Awake
“Since the brain is about 75 percent water, any mild dehydration can negatively affect cognitive function, concentration, attention, and memory. That’s why drinking water helps the brain stay hydrated and function as expected,” he explains. He adds: “Without water, the brain’s blood volume can decrease, which reduces the oxygen supply to the organ.”
The professional explains that although coffee contains caffeine, which is a stimulant and can increase short-term attention and concentration, it can also increase brain dehydration, as it inhibits adenosine receptors in the brain. This, in turn, leaves the organ more awake and, therefore, will stimulate catecholamines, adrenaline, noradrenaline, and so on.
“This is why, indirectly, coffee can have a diuretic effect and, therefore, is not a mechanism of choice to give more energy to the individual who finds himself having an entire night of sleep deprivation,” the doctor emphasizes.
In addition, the neurosurgeon also says that a bad night’s sleep or insomnia can affect the release of antidiuretic hormone from the hypothalamus, which is an important brain structure in regulating the circadian rhythm.
“Often, the lack of disposition and energy is linked to the low volume of sleep that the individual has, that is, he ends up not having the substance that protects the loss of fluids from the body. Therefore, a recommendation for those who have slept little or have ended up staying overnight, voluntarily or not, drink more water than normal”, he concludes.
