Appropriate amount of coffee is good for your health, but some people are sensitive to caffeine, and drinking it will increase your physical inappropriate symptoms. A neurosurgeon said that after quitting coffee, he increased his attention and relieved his anxiety, which overall benefits outweighed the disadvantages.
Goodie, a former neurosurgeon who graduated from MIT, shared on YouTube that he quit coffee for two reasons. The first is that coffee has a diuretic effect, which makes people drain water. After draining water, it will cause inattention and caffeine will keep people awake. The purpose of drinking coffee was to refresh themselves, but although they were energetic, their concentration was affected, and the two effects were contradictory.
Goo die shows an example of a spider. NASA, the US Space Administration, used spiders to do some experiments and gave spiders several drugs, including marijuana, methamphetamine (similar to methamphetamine), diacetamide (LSD, a neuropsychedelic agent) and caffeine. The first three types of websites are still complete, but the only ones that are produced from caffeine (bottom right) are quite rude; Goodie said that this is how he feels after taking caffeine, and his brain is in a mess.
Goodie proposed the second point. He is a person who is more prone to anxiety. When he feels anxious, taking caffeine will add to the anxiety and hinder the self-thinking mode.
Goodie said that she had quit caffeine-containing foods, including coffee, red beef energy drinks, tea and chocolate, etc., and her head hurts in the first four weeks, like someone using a tiger's calf to snail the sun. The pain slowly resolves from the surroundings. The whole person becomes focused and alert, with clearer thinking and no longer affected by caffeine. Like a spider, it can create a perfect network in the brain.
According to the US "Mental Illness Diagnosis and Statistical Manual", excessive caffeine extraction can cause excessive stimulation of the middle nervous system. If the following five symptoms occur after caffeine extraction, it means that caffeine poisoning has occurred:
‧Acquiring at least 100 mg Symptoms that occur after caffeine (about the amount of coffee that is brewed) include:1. Freshness
2. Firmness
3. Endurance
4. Insomnia
5. Fine tides
6. Increased urination
7. Gastrointestinal disorders
‧Intake a higher content of caffeine (more than 1 gram per day):
1. Muscle twitching
2. Speech disordered
3. Fast heartbeat, arrhythmia
4. No fatigue period
5. Mental irritability
6. Poor appetite
and coffee can also affect sleep. Caffeine may cause more difficulty falling asleep, affecting deep sleep time, and more likely to wake up in the middle. Therefore, if you are particularly anxious or sleep disordered, it is recommended to drink as little or not to drink coffee.
According to the Food and Drug Administration (FDA), the maximum daily intake of ordinary people is 400mg. For example, the Starbucks large cup of American style is 225mg, and the large cup of iron is about 150mg. However, it is not to say that caffeine is not good at all, including antioxidant, reducing all-cause mortality rate, cardiovascular disease mortality rate, etc. Everyone is still judged based on their physical feelings after drinking coffee.
