No thirst signals, watch out for dehydration
Ignore incentiveYou are busy and have a lot of appointments or you have to be in the car for a long time. Then it is annoying when you often have to go to the bathroom. Many people want to prevent this by drinking less, because whoever drinks less has to go to the toilet less often. You deliberately ignore the thirst stimulus.
When this happens occasionally, this is not a problem. We usually get thirsty when we have lost about two percent of body fluids and then we are far from drying out. Only if we ignore the thirst stimulus often enough, it will eventually take longer and longer before we feel it and then it can entail a health risk.
Hunger instead of thirstSometimes the body gives a signal if you ignore the fluid deficiency for too long. You will then feel hungry. Your body then asks for food, while you are actually thirsty. When the feeling of hunger disappears after drinking a few glasses of water, chances are that it was not hungry, but thirsty. Many people eat too much, while they are actually thirsty instead of hungry.
Dehydration (dehydration) and headacheWhen you suffer from dehydration, headache is often the first phenomenon. It seems that fluid deficiency is the most common reason for headache. So it's not a bad idea to drink a few glasses of water empty when you feel a headache coming.
It is not known exactly why we get a headache from drinking too little. It is assumed that the brain is the first to give clear signals when they are not given enough fluid and waste accumulates. It is also your brain that first signals that you are drying out. The hypothalamus is the part of the brain that causes the thirst stimulus, and when you ignore this, a stronger signal comes in, headache.
Other early signs of dehydrationIf you drink too little chronically, you may occasionally have a headache, but there are other symptoms that should actually encourage you to drink more. These are:
- the color of the urine. Urine should be light yellow in color. When the urine is dark yellow, this is already a sign that you drink too little.
- little energy. If you often feel tired and lifeless, this may be due to a lack of moisture.
- dry lips and dry skin. If you always drink too little, your body will be the first to extract moisture from the skin.
- bad mouth odor. Not everyone notices a dry mouth, but when you start to stink out of your mouth a dry mouth may be the reason because of insufficient saliva production.
- dry eyes. Too little moisture will also produce less tear fluid, causing you to suffer from dry eyes.
