Children and young people who consume energy drinks containing caffeine may also suffer from sleep problems and anxiety. 5-7 Overdose On the other hand, some studies suggest that caffeinated beverages may worsen gastroesophageal reflux disease (GERD) in some people. This seems to be especially true of coffee ( 23, 24, 25). Grosso G, et al. Coffee, caffeine, and health outcomes: An umbrella review.

Giving up caffeine after using it for a long time is challenging because the body has to get used to functioning without it. Withdrawal symptoms usually start within 12-24 hours after the last dose. The symptoms can last for around 2-7 days, or even longer for people who consume a lot. 2 Caffeine is a bitter, white crystalline purine, a methylxanthine alkaloid, and is chemically related to the adenine and guanine bases of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is found in the seeds, fruits, nuts, or leaves of a number of plants native to Africa, East Asia and South America, [18] and helps to protect them against herbivores and from competition by preventing the germination of nearby seeds, [19] as well as encouraging consumption by select animals such as honey bees. [20] The best-known source of caffeine is the coffee bean, the seed of the Coffea plant. People may drink beverages containing caffeine to relieve or prevent drowsiness and to improve cognitive performance. To make these drinks, caffeine is extracted by steeping the plant product in water, a process called infusion. Caffeine-containing drinks, such as coffee, tea, and cola, are consumed globally in high volumes. In 2020, almost 10 million tonnes of coffee beans were consumed globally. [21] Caffeine is the world's most widely consumed psychoactive drug. [22] [23] Unlike most other psychoactive substances, caffeine remains largely unregulated and legal in nearly all parts of the world. Caffeine is also an outlier as its use is seen as socially acceptable in most cultures and even encouraged in others. Lucas M, et al. (2013).

One review reports that after participants ingested 37.5–450 mg of caffeine, they had improved alertness, short-term recall, and reaction time ( 1). Caffeine acts as a central nervous system stimulant – making you more alert and focused, but potentially also more irritable and anxious. It’s all to do with your body’s adenosine receptors, which help to regulate your heart rate, blood flow and sleep-wake cycles. When adenosine – an organic compound that occurs naturally in your body – binds to these receptors, it triggers physiological responses that lead to a decrease in cellular activity, often promoting drowsiness and sleep. A systematic review and meta-analysis from 2014 found that concurrent caffeine and L-theanine use has synergistic psychoactive effects that promote alertness, attention, and task switching; [57] these effects are most pronounced during the first hour post-dose. [57] Physical performance In a small study, when five healthy adults drank caffeinated water, they experienced a relaxation of the muscle that keeps stomach contents from moving up into the throat — the hallmark of GERD ( 25).

Obviously, if you drink half a pint of milk and two sugars in your latte, it increases the calorie count; is there any way to mitigate that? With a sprinkle of cinnamon, perhaps? “It’s probably not going to have a huge effect on fat-burning,” says Nelson. “There are some studies showing that it may help with glucose metabolism if you give it in a pretty high dose – so if you’re looking at glycemic control, it may be helpful for that. But I wouldn’t count on a little dusting doing much good.” It’s not a natural source of caffeine, but manufacturers may include caffeine in their recipes. This has made chewing gum popular among some athletes and others looking for an energy boost.Studies have also found that people who drink coffee regularly have a lower risk of developing Alzheimer’s and dementia, and cut suicide risk by 45 percent. These benefits are limited to people who drink high-octane coffee, not decaf. Some people consider coffee to be a health drink, but like most foods, over indulging can cause side effects.
