Coffee and tea are both super healthy beverages. The majority of them consist of Caffeine, which can enhance your mood, digestion, and mental and physical effectiveness. In addition, studies have shown that when ingested in low quantities, it is safe for most people. On the other hand, coffee in high doses can have uncomfortable and even risky side effects.
1.) Anxiety
Caffeine has been shown to enhance attentiveness. It works by inhibiting the impacts of adenosine, a brain substance that causes tiredness. This, in turn, triggers the release of adrenaline which happens to be a hormone and is connected with increased energy. However, at larger concentrations, such impacts could become more pronounced, resulting in Anxiety.
2.) Insomnia
One of Caffeine’s greatest treasured properties is its ability to keep people awake. But, on the other hand, Caffeine could indeed make it very difficult to get enough quality sleep. According to studies, Caffeine tends to increase the amount of time needed to fall asleep. This may reduce nighttime sleep, particularly in the elderly. Low and moderate amounts of Caffeine, on the other hand, do not appear to have much of an effect on sleep in people who are considered “great sleepers” or even those who have self-reported insomnia.
3.) Digestive Problems
Countless people have found that coffee helps them get their bowels moving every morning. The purgative impact of coffee has been attributed to the availability of gastrin, a hormone produced by the stomach that increases activity in the colon. On the other hand, Caffeine appears to enhance intestinal moves by increasing peristalsis, the contractions that move food through the digestive system. Provided this effect, it’s not shocking that high caffeine doses can cause watery stool or even diarrhoea in some people.
4.) Muscle Degeneration
Rhabdomyolysis is a potentially fatal ailment in which broken fibers travel through the bloodstream, causing kidney problems and other complications. Mental anguish, infection, drug addiction, muscular pain, and bites from venomous snakes or insects are common causes of rhabdomyolysis.
In one particular instance, a woman experienced drowsiness, puking, and dark urine after consuming 32 ounces of coffee containing approximately 565 mg of Caffeine. She recovered, thankfully, after already being treated with medicines and liquids. Notably, this is a large amount of Caffeine to intake in such a short amount of time, particularly for somebody who is not used to or is highly sensitive to its impacts. To minimize the risk of rhabdomyolysis, restrict your caffeine consumption to around 250 mg per day unless you’re accustomed to consuming more.
5.) Addiction
Amidst all of the nutritional benefits of Caffeine, there is no doubting that it has the potential of becoming habit-forming. According to a comprehensive review, while Caffeine stimulates specific brain chemicals in the same way that cannabis and amphetamines do, it still does not affect classic addictive behaviour in the same way that all these drugs do. Even so, at large doses, it may cause psychological dependence.
6.) Blood Pressure Is Excessive
Caffeine does not lead to an increased risk of strokes and heart attacks in most people. However, due to its stimulating effect on the nervous system, it has been shown in so many studies to elevate blood pressure. High blood pressure is a health risk for heart attack and stroke as it can damage arteries with time, limiting blood supply to the heart and brain. Caffeine’s changes in blood pressure appear to be transient. This also appears to have the greatest impact on people who aren’t used to drinking it. Caffeine consumption has been shown to raise blood pressure during a workout in healthy individuals and those with moderately high blood pressure.
7.) Increased Heart Rate
Caffeine’s stimulatory effects might indeed cause the heart to beat quicker. This may cause a modified heart rate rhythm known as atrial fibrillation, noted in youths who consumed caffeinated beverages containing exceptionally high caffeine doses. Inside one case study, a female who took a huge dose of caffeine granules and tablets in an attempt to commit suicide advanced a rapid heartbeat, kidney failure, as well as other serious medical conditions. Even so, this impact doesn’t appear to be universal. Undoubtedly, several other people with heart troubles may be able to endure high levels of Caffeine without experiencing any adverse side effects.
8.) Fatigue
Caffeinated beverages such as coffee, tea, and sports drinks are well recognized to increase energy levels. Those can, however, have the reverse effect by causing rebound tiredness after the coffee has left your system. According to one evaluation of 41 studies, while caffeine-containing drinks enhanced wakefulness and mood for many hours, attendees were frequently more tired than usual the next day. Of course, if you keep consuming high levels of caffeine during the day, you will avoid the rebound effect. On either hand, this could impact the ability to sleep. To maximise its energy advantages and minimise rebound fatigue, caffeine should be consumed in moderate instead of large doses.
9.) Immediacy And Increased Urination
Because of the stimulatory effects of drinking coffee on the bladder, elevated peeing is a known side effect of excessive caffeine consumption. You may well have observed that you need to urinate more frequently when you sip so much coffee or tea than usual.
10.) Caffeine Has Been Connected to Gout Attacks
According to this research, people who live on caffeinated drinks are more likely to have a gout flare-up.
11.) Women’s Breast Tissue Cysts
According to one survey, “women who drank 31–250 milligrams of caffeine per day had a 1.5-fold rise in the odds of creating fibrocystic breast disease, and women who drank more than 500 mg per day had a 2.3-fold rise in the odds of emerging cysts.”
12.) Coffee May Be Harmful to Type 2 Diabetics
According to an American Diabetes Association study, Caffeine impairs glucose metabolism in patients with type 2 diabetes.
13.) Caffeine Hypersensitivity
Some people are hypersensitive to the caffeine particle, resulting in allergic-like reactions such as hives and pain. Although not a genuine allergy, many people experience severe signs after intaking even small quantities.
14.) Menopause Symptoms Worsen
Menopausal women who drank Caffeine had a higher level of vasomotor symptoms, according to a current study published in The Journal of The North American Menopause Society.
15.) Caffeine Inhibits the Formation of Collagen in The Skin
This impact is dose-dependent, but coffee drinkers must be conscious.
