“Caffeine is the most consumed psychoactive compound in the world. Even if you don’t drink coffee or tea, you most likely consume caffeine regularly, since it’s found in everything from soda and flu remedies to decaffeinated coffee and chocolate,” he noted. Adam Taylor, director of Lancaster University Center for Clinical Anatomy Studies, to the digital health magazine The Conversation.
According to specialists, caffeine is one of the compounds that the body absorbs most quickly. Its maximum effect is reached in two hours and elimination from the body can take up to nine hours. For adults, it is recommended that they consume no more than four cups of coffee a day, which is approximately equivalent to 400 milligrams of caffeine per day.
In this regard, in very extreme cases, excessive consumption could cause muscle tremors, nausea and a strong heartbeat. But on the other hand, giving up caffeine immediately can cause headaches, fatigue, and tiredness. Most commonly, headache is the most common withdrawal syndrome; the component narrows the blood vessels in the brain area, which reduces circulation. When you stop drinking, the region returns to normal, increasing blood flow and this causes pain.
Regarding coffee consumption, it affects sleep when consumed late in the afternoon and at night. According to studies, caffeine delays the release of melatonin for 40 minutes and also shortens the period of deep sleep, increasing tiredness the next day. For this reason, by stopping drinking this infusion, sleep improves in just twelve hours.
It is important to note that eliminating caffeine also could cure indigestion. Drinking coffee induces the secretion of acid in the stomach and weakens the esophageal sphincter, which controls the reflux of stomach contents into the esophagus, causing heartburn. However, not all people are affected in the same way by consumption; some research shows that there is a genetic component between tolerance to caffeine and how it impacts metabolism.
Giving up caffeine also improves food tasting, giving greater sensitivity in drinks and sweet dishes. Even, from an aesthetic level, giving up coffee could result in a whiter teeth. The yellowish stains that this type of infusions promote are due to the tannins that pigment the teeth.
“As with many things, the key is moderation. But if you’re seriously considering eliminating caffeine from your diet, the best way to do it is gradually. Doing it overnight will cause side effects such as headaches and fatigue that could last two to three weeks. How long these effects last depends on how much caffeine you have consumed daily and how long you have had the habit,” Taylor concluded to the British portal.
