Caffeine is a stimulant and it does affect the central nervous system. In as little as fifteen minute’s the caffeine enters the blood stream and gives you an effect as awake in your body. Caffeine has also been known to increase the human body’s mental alertness and it’s cognitive functioning, as well as enhancing the human body’s physical performance by improving endurance and reaction time your human body has. So how does it work? Caffeine is able to mimic something known as a neurochemical in the human brain called adenosine, which is produced by the neurons throughout the entire day. Your nervous system monitors adenosine levels and as it increases, your body starts to slow down, preparing your body for the evening in which you need to sleep.
Caffeine latches onto the brain’s receptors for adenosine and pushes them out of the way – with the result that we are felling more alert and awake.
So is it possible to overdose on caffeine? Before you laugh that off. Well it is actually possible to overdose on caffeine, and symptoms include confusion and hallucinations as well. According to a caffeine calculator designed by Caffeine Informer, if you weigh 60 kg, you should have a maximum of 2,2 cups of coffee a day (based on a 236 ml serving).
Consume 55.4 cups and you can overdose and die! So, the good news is you probably won’t die from drinking too much coffee – but beware of energy drinks that contain high concentrations of caffeine and are easier to chug down in quick succession. It is very unhealthy.
The Mayo Clinic recommends about 400 mg of caffeine per day for healthy adults. So like everything in life, moderation is key to maintaining health.
If you’re not used to drinking coffee, you are also at risk of some side effects such as feeling shaky. If you suffer from an anxiety or sleep disorder, it’s probably a good idea to steer clear of caffeine and do not use it.
Can I suffer from withdrawal symptoms?
Yes! Because caffeine is a stimulant it will affect your body negatively if you suddenly stop consuming it. You can expect to feel anxious, irritable and drowsy. The good news is that the side effects are temporary.
