I'll see you there, my friends. It's really fascinating to me the reason why it is that caffeine keeps us awake when consumed in a particular amount, of course. And I can't actually remember when I first learnt about this. But, I don't know, I think there's something curious about it. And if you're not familiar, let me see if I can try and explain a little bit about it. So, when we feel tired, what builds up in our brains is referred to as in sleep science as sleep drive or sleep pressure and that sleep pressure is a literal build-up of a particular neurotransmitter called adenosine and there are receptors in the brain for adenosine specifically And there is a correlation between the amount of adenosine that has built up and been received by these receptors and how tired we feel at night or indeed at any time that we feel tired or have lacked sleep.
And of course this is not the only thing that makes us sleepy. It's quite a complicated part of our biology. There are many other factors that need to combine to create sleepiness as we know it. But this is certainly one of the bigger parts that contributes towards the feeling of sleepiness and The reason that caffeine keeps us awake is because it is actually molecularly rather similar to adenosine in shape, as such that it is actually capable of fusing with the adenosine receptors in the brain. Effectively clogging them up and blocking the ability of the actual adenosine to connect and send these signals to our brain to let us know that we are in fact tired. And anyone that has experienced the wakeful effects of caffeine
will be able to empathize, relate to that feeling of your body indeed being tired, but an inability to actually fall asleep. I know that I've experienced this Several times when I've had too much caffeine. Too close to bedtime. And then I'm sure if you've done the same you will know exactly the feeling that I'm talking about when you're laying awake.
