Tinnitus has many different ways it presents itself and has a large number of other potential causes. Tinnitus consists of a constant ringing of the ears that is not caused by outside stimulation. The jitters are caused by the increased buildup of adrenaline and represent an upper extreme of the effects caffeine can have on your sympathetic nervous system. If you have ever had a really strong cup of coffee or have overdone it with your caffeine intake, you have most likely experienced the caffeine jitters. When the body perceives a threat, it leads to the secretion of the hormone adrenaline, which increases cardiac output, alertness, respiration rate, and much more. The sympathetic nervous system, also referred to as the fight-or-flight response, is a biological response to stress. Adrenalin StimulationĪnother way that caffeine impacts the body is that it stimulates the central nervous system and causes the activation of the sympathetic nervous system. Luckily symptoms of dependence are quickly resolved in a week or so. While useful in the short term, frequent consumption of caffeine can create a reliance where the body needs caffeine to even have a baseline level of alertness. Specifically, caffeine interferes with the neurotransmitter adenosine within the brain.Ĭaffeine competitively binds to adenosine receptors in the brain, which inhibits adenosine binding.Īdenosine plays a significant role in helping the transition to sleep, and when its binding is inhibited, the body feels more alert. The main mechanism of caffeine is that it interferes with a neurotransmitter in the brain. The small molecule also can stimulate the sympathetic nervous system, which increases your overall alertness and activates the fight or flight response.īelow is a closer look at the two ways that caffeine affects the body. CaffeineĬaffeine is able to cross the blood-brain barrier and interact with the receptors in the brain to reduce fatigue, increase alertness, and essentially trick the brain into being more alert and awake. Below is a closer look at the science behind caffeine and tinnitus, as well as everything you need to know to help you manage your tinnitus symptoms. People that find some tinnitus relief with lifestyle modifications may wonder if their caffeine habits can contribute to an increase in tinnitus symptoms. It can be found in your morning cup of coffee, afternoon tea, and evening soda beverage with your dinner. Medications, stress, and a high sodium diet may all affect tinnitus-related symptoms, and making changes to your day-to-day could help.Ĭaffeine is a molecule that many people are all too familiar with. It can differ significantly, with some people having a permanent ringing in the ears and others with the intermittent ringing of the ears.įor those with tinnitus, certain triggers can be controlled to help mitigate its severity. Tinnitus is a condition that is characterized by a phantom ringing in the ears that is not caused by a sound in the immediate environment. Make sure you pay attention to what conditions are best for you to avoid tinnitus.” - Drew Sutton, MD, Board-Certified Otolaryngologist Everyone may have different experiences at different times. Please note: A surprising number of products contain caffeine, and some have a lot more than what you think.Įven decaffeinated drinks still contain caffeine – although only a small amount such as decaf brewed coffee.Įducation is the best way to prevent an allergic reaction to caffeine.“Although there is little concrete proof about causation of tinnitus, be aware of what things seem to bring on the ringing or help stop it. It may take up to 2 weeks for all of caffeine’s effects to wear off. Assess whether your symptoms have disappeared.There may be a period of caffeine withdrawal where you actually feel worse. Eliminate these products from your diet.Explore our extensive Caffeine in Food database as well as our Caffeine in Beverages database in order to be aware of all the products that have caffeine listed as an ingredient along with the amount they contain.If you have a reaction to coffee but not other caffeinated products, there’s a good chance that you are sensitive to mycotoxins and not the caffeine. They’ve identified 18 different mycotoxins that are commonly found in coffee and found that the levels in decaffeinated coffee are often higher than that of regular coffee. A recent study 3 from the University of Valencia in Spain found that commercially sold coffee is often contaminated with mycotoxins. Mycotoxins are essentially chemicals produced by fungi and they can produce all kinds of negative reactions when ingested by humans.
