![]() Consuming caffeine can cause tremors in people who aren’t used to it or get more than usual. Some people experience an upset stomach when they reduce their caffeine consumption. You may feel grumpy if you cut back or even delay your first cup of the day. Caffeine has a positive impact on energy levels and mood. If you stop consuming caffeine, those receptors are no longer blocked, and you feel the effects of adenosine. Caffeine provides an energy boost by blocking receptors for a neurotransmitter called adenosine, which makes you drowsy. Anxiety can be particularly intense if your caffeine is accompanied by sugar (as an addition to coffee, in soda, etc.). It’s thought there are physiological and psychological reasons for this reaction. People who abruptly stop consuming caffeine may experience anxiety. Experts believe that if you stop consuming it, your blood vessels expand, blood flow accelerates, and the added pressure gives you a caffeine withdrawal headache. Caffeine causes blood vessels in the brain to constrict, slowing blood flow. ![]() This is often the first symptom people notice when reducing their caffeine consumption. Nine of the most common caffeine withdrawal symptoms are: ![]() This article identifies those symptoms and provides recommendations for coping as your body adjusts.Ĭutting your caffeine intake rapidly can affect your body in several ways. And you know that if you cut back on your intake, you’ll experience caffeine withdrawal symptoms. If you consume caffeine regularly, you probably also understand that your body has become used to it. That’s because it’s a central nervous system stimulant that affects nerve activity in the brain. ![]() If you enjoy beverages containing caffeine, you know it’s effective in increasing alertness and reducing fatigue. It’s unclear if the same principle would apply in a clinic, however, the study suggests there may be ways to implement similar open-label placebos for drug dependence while remaining ethical.American adults consume an average of 200 mg of caffeine daily (the equivalent of two five-ounce cups of coffee), and many people can tolerate twice that amount with no ill effects. Researchers concluded that giving someone decaf can reduce their caffeine withdrawal symptoms, even if that person doesn’t expect decaf to help. The study notes giving someone experiencing withdrawal a placebo is proven to help reduce their symptoms, however, it is not ethical to do so in a clinic. ![]() While it wasn’t as large of a drop as measured in the deceptive group, researchers say the placebo effect is still strong in the open-label group. Reasonably, they thought caffeinated coffee would help reduce symptoms the most, followed by water, however, they expected decaf coffee to help the least.įorty-five minutes after drinking their respective beverages, researchers measured the groups’ withdrawal levels and found “a significant 9.5-point reduction in caffeine withdrawal” amongst those who were aware they were drinking decaf coffee. A second “open-label” group was given decaf and told it was decaf, while third control group was given water.īefore they were tested, the 61 participants ranked how they expected caffeinated coffee, decaf coffee, and water to affect their withdrawal symptoms. The first, which the study refers to as the deceptive group, was given decaf and told it was regular coffee. Researchers from the University of Sydney tested 61 heavy coffee drinkers by splitting them into three groups. The health agency says, depending on the substance, withdrawal can be “extremely debilitating” and make it difficult for someone to stop using or lower a dosage. Drinking decaffeinated coffee can help reduce symptoms of withdrawal in heavy coffee drinkers, even if they know it’s decaf, according to a new study.Īccording to Health Canada, withdrawal is a “reaction that may occur when a person reduces or stops taking drugs or alcohol after using regularly for a long time or after using high doses.” ![]()
