No Coffee Before Davening - Rabbi Ari Zahtz

so i just saw a fascinating study that indicates that one should not have coffee as soon as one wakes up in the morning and the reason is that assuming you wake up in the morning your body starts to produce cortisol which gives you the energy to get out of that groggy state and start your day as it turns out coffee interferes with the production of cortisol so in order to get us out of the grogginess of the morning without the cortisol it's going to require even more coffee in order to try to get to the same point but if you wait an hour an hour and a half before that cup of coffee it actually becomes that much more powerful what does that have to do with anything so maybe that's the understanding of the one is not supposed to eat or drink before davening water is okay technically speaking tea and coffee are okay but maybe the idea behind it is that if the first thing that we do is we turn to akrishboro and we wake up in the morning and we dive in and then after we dive in after we dive in we then after i've been up for a while have the energy of our fila have the energy of our cortisol and then the energy of our coffee will actually be the most effective you
