Caffeine is a stimulant found in plants that provides multiple benefits. These include reduced risk of depression, Alzheimer's, Parkinson's, heart disease, and diabetes. Aside from these, caffeine can also stimulate the production of dopamine, to increase motivation and productivity, and acetylcholine to enhance memory and learning.
Since it is an addictive substance, you can become dependent on it. When you consume more and more caffeine, you start to depend on the so-called “caffeine high” that you experience as a result of caffeine's psychoactive properties. For this to happen, caffeine binds to receptors in the brain that are usually reserved for adenosine, a chemical that relaxes the nervous system. Since adenosine can't bind, your brain will not feel tired and would continue to produce stimulants for the different brain functions. This leads to an overall feeling of alertness, focus, and motivation.
Unfortunately, regular caffeine intake can alter brain chemistry. The adenosine molecules that have nothing to bind to will signal your brain to make more receptors for it, making it impossible to achieve the desired caffeine high with the usual caffeine intake. In terms of addiction, this is the part where tolerance against the addictive substance is developed. Since your brain has become more tolerant of caffeine, there has to be an increase in intake to get the usual response.
Once your brain has been altered to have more receptors, the effects of not getting caffeine will worsen. Without a supply of caffeine, the receptors are now available for adenosine to bind to. This induces a feeling of extreme tiredness and other symptoms of withdrawal, just like in other addictive substances. Other withdrawal symptoms may include:
These symptoms may be difficult to get through but they are part of the road to recovery. Some tips on how to ease withdrawal symptoms include:
Although caffeine has become a crucial part of the day for many, it is important to remember that caffeine isn't completely healthy. It is an addictive substance that can cause harm to the body without people even noticing it. This is why it might be best to just avoid it.
