Is Caffeine Effective?
Caffeine is considered a drug and as a drug, it has a tendency to change the physical or mental state of a person.
The reason behind caffeine being an effective drug is that it is similar to adenosine receptors. Adenosine is responsible for making a person feel tired and sleepy over time. The more you stay awake, the more adenosine chemical accumulates in your brain.
However, caffeine is similar to adenosine molecules in structure. It attaches itself to the adenosine receptors and makes you alert within a few minutes. In this way, it can give you the feeling of awakeness and activeness immediately.
How Long Does Effects of Caffeine Last?
Caffeine has a half-life of around 6 hours. After 6 hours, the amount of caffeine present in your body reduces to half. Eventually, after another span of 6 hours, it almost ends.
So if you have consumed 200 mg of caffeine, after 6 hours it will be left to 100 mg and then after another 6 hours, it will drop down even more.
Once it will end, you might start feeling tired and craving more caffeine.
You must have noticed that regular caffeine consumption can decrease the effects of caffeine over time and then you require more caffeine. Do you want to know why? Then do not stop here.
When an individual consumes caffeinated drinks and the molecules of caffeine bind themselves to adenosine receptors, they temporarily make you active.
However, when you regularly drink caffeine so your brain creates more adenosine receptors. These multiple receptors require even more caffeine molecules to produce the effects of alertness then.
However, if you do not increase your caffeine consumption then you start feeling more tired. The reason is that when not enough caffeine molecules are present to attach themselves to the increased adenosine receptors then adenosine molecules attach themselves to the receptors which makes you even more fatigued than before.
Over time, this pattern develops caffeine tolerance and then you need more of it.
Is Caffeine addictive?
Like other drugs, caffeine can cause an effect similar to addiction. However, it is not like a typical drug or typical addiction which can temper your brain in the way other drugs do.
Caffeine slows down the reabsorption of dopamine in the body. As dopamine leaves the brain at a slower rate, caffeine can have effects such as providing more pleasure. This is quite similar to the function of cocaine but to a milder range.
However, drugs like cocaine are still different than caffeine due to their mechanism. Instead of caffeine addiction, the term caffeine dependency is preferred.
Caffeine dependency means when you start needing caffeine. However, when this need is not fulfilled so a person starts feeling various side effects. These side effects or symptoms are called caffeine withdrawal symptoms.
Withdrawal Symptoms of Caffeine
When a person faces caffeine deprivation then he starts feeling a caffeine withdrawls symptoms. The signs of caffeine withdrawal are:
- Muscle pain and stiffness
- Nausea and vomiting
- Less concentration.
When Does Caffeine Withdrawal Start Taking Place?
The duration when an individual starts feeling caffeine withdrawal symptoms varies. However, these symptoms start showing up after 12-24 hours of consuming caffeine when your system starts flushing caffeine out.
The symptoms can become severe after a day of going without caffeine. But people who are highly dependent on caffeine can feel these symptoms in less than 3 hours and giving up coffee or caffeine becomes quite hard.
How Long Does Coffee Keep You Awake?
Caffeine can keep you awake and the most active for at least 6 hours after you consume it.
When the amount of caffeine starts decreasing and the adenosine molecules start attaching themselves to the receptors, you start feeling drowsy and sleepy.
What is the Best Time to Drink Caffeine?
There is not a particular best time for consuming caffeine. However, it is said that it should be drunk in the late morning. The reason is that when a person wakes up, he or she has high cortisol levels which keep him/her alert.
Consuming caffeine can increase cortisol levels which are already high. This can interrupt the function of the normal immune system.
Therefore, once you wake up, wait for 2 to 3 hours to consume caffeine. However, the research is still going on.
