For those who struggle to drink the recommended eight glasses of water a day, we have good news: a new study suggests that this “rule” does not necessarily apply to everyone.
Instead of that, the research shows that there is simple way to find out how much water should you drink per day – you just have to listen to our body.
This might sound pretty unclear, but the researchers were able to demonstrate for the first time that when people do not need to drink water anymore, it physically gets difficult to swallow up.So, specifically, we should listen to our throat.
This is the first time to identify the mechanism that regulates the intake of fluids and prevents from excessive drinking, and it encourages the fact that the water needs for each person are different.
The researcher Michael Ferrell from the University ‘’Monash’’ In Australia stated that we will do better for our body if we listen to what our body requires of us, so instead to drink water according to a schedule you should drink according to your thirst.
The good news is that even if you are drinking the eight glasses of water every day according to a schedule you probably will not cause any kind of harm, but some people need even more water and some less.
So having this in mind, we know when we need to drink water due to thirst, so how to know when it is enough for us?
Excessive drinking is actually a real problem and can lead to something called water intoxication or hyponatremia – when levels of sodium in the blood becomes too small that can lead to serious problems ranging from lethargy and nausea to seizures, coma and even death.
So far, no one was able to discover how the body regulates this and what is that that prevents us from drinking too much water.
In his research, Farrell and his team asked 20 participants to assess the amount of effort needed to swallow the water under two conditions: after exercise when they were thirsty, and then later when they were persuaded to drink some extra water.
The team discovered that the effort was increased by three times after the people drank too much water – which is indicator that the body is regulating the amount of water that is entering which makes it to be physically harder to be consumed.
The team also used functional magnetic resonance imaging (fMRI) to measure brain activity before people can drink the water under these two conditions, and when they consumed too much water that had greater activity in the right prefrontal area of the brain.
This suggests that the frontal cortex intervenes to suppress the discomfort during swallowing the water so the participants can drink the amount of water needed by researchers.
Although the research includes a small number of samples, however, it is a positive first step in beginning to understanding how our body controls fluid intake and can help people to make better choices about drinking water – especially if they are struggling to achieve daily needs and are forced to swallow a certain amount of water.
Further research is needed to confirm these results, and that the discomfort in swallowing is a response to excessive drinking.
In the meanwhile you should listen to your body. If your body really does not want more water, then it can mean something.
