Medical Video: Is Coffee Bad for You? | Dr. Josh Axe
Drinking coffee is a routine for some people to start the day. Coffee can repel sleep while increasing enthusiasm and concentration. Unfortunately, not everyone feels refreshed and alert after drinking coffee. Drinking coffee actually makes some people become weak and more tired than before. Why is that, huh? Consider the following review.
Limp body after drinking coffee, why?
Coffee contains caffeine, which is a stimulant that can increase energy and make you refocus. Unfortunately, not everyone feels the same effect. There are some people who do not feel any adverse effects after drinking several cups of coffee, some are feeling exhausted after just drinking one cup.
Reporting from Healthline, drinking coffee does not immediately make the body limp. There are several body reactions to caffeine which reduce energy and eventually make the body tired, such as:
1. Caffeine blocks adenosine
When you are awake, a chemical called adenosine gathers around the brain. These chemicals act to regulate the cycle of wake and sleep. Usually, during the day the levels of adenosine will increase so that brain activity slows down. That is why you become powerless, out of focus, and sleepy during the day. After you sleep, adenosine levels will decrease by themselves.
When you drink coffee, caffeine moves with the blood and will circulate around the brain. This causes a reaction between caffeine and adenosine. Initially caffeine will ward off adenosine and prevent the body from becoming limp, but the effect does not last long.
Within a few hours of drinking coffee, the effects of caffeine will disappear and adenosine which continues to be produced by the brain will again dominate, even in greater numbers because you really haven't slept. Yes, coffee really cannot reduce the production of adenosine. Caffeine in coffee is only able to inhibit adenosine from entering special receptors in the brain. Again, adenosine production will only decrease when you sleep.
Then, the more caffeine consumed, your wake and sleep cycle can be disrupted. You will most likely have trouble sleeping. Over time, your body will feel very tired because you don't get enough time to rest.
2. You go back and forth to the bathroom
Caffeine contained in coffee is diuretic, which encourages the body to produce a lot of urine. This makes you have to go back and forth to the bathroom. You are also at risk for dehydration.
When urine continues to be produced, blood will lose fluid. This affects the blood vessel system in the heart. As a result, the heart rate will be faster and blood pressure will decrease. The longer, the body will become more tired because it continues to work hard. For that, be aware of the appearance of symptoms of dehydration such as weakness, headaches, and dark urine if you drink coffee frequently.
Caffeine also causes vasoconstriction, which is narrowing of the arteries and affecting blood flow. This is related to headache symptoms in people who like to drink coffee.
3. Coffee contains added sugar
Coffee often contains added sugar. When you drink coffee, your body processes sugar faster than caffeine. This process causes your energy to be replenished suddenly.
However, after that you are likely to experience a drastic deterioration in energy, usually after 90 minutes of sugar is consumed along with coffee. Finally, the deterioration of energy makes your body sluggish and weaker than before.
4. Caffeine causes fatigue of the adrenal glands
The adrenal gland is above the kidney and functions to produce many hormones that regulate energy, mood, and overall health. When you drink coffee, caffeine triggers the adrenal gland to respond while producing hormones, one of which is cortisol.
The more caffeine consumed, means the adrenal gland continues to be active and eventually causes fatigue of the adrenal glands. In addition, the production of the hormone cortisol can make it difficult for you to sleep at night and reduce your stamina the next day.
If you often feel symptoms of fatigue and weakness, try to pay attention to your coffee drinking habits. Consider reducing coffee intake and drinking just enough. However, do not reduce coffee intake suddenly because it can cause headaches. The body needs time to adapt to substances that normally enter the body.
