I love to start my morning with a cup of coffee together with millions of us. There is something about that deep, bitter flavor that makes everything else sweeter in the morning. I like my coffee long, like I never want this moment of bliss to end. Some see it as a vice, other are worried if the health benefits are true. The consistent consumption hasn’t been studied on a long term clinical trial. Many things we take for granted aren’t and coffee is not at the top for this kind of research.
One main question remains. Does coffee affects hydration? The traditional idea that coffee is a diuretic it’s a given.
Recent research shows no changes in water content of tissues or blood plasma, in a trial, comparing water consumption against coffee. But this is just the tip of the iceberg on what coffee does to our brain. The chlorogenic acids (CGA) is emulating cortisol in the brain. Cortisol is the hormone that is waking us up in the morning using water. Does the link between low morning cortisol levels found in the population accounts for the huge amount of coffee consumption? Blue light from devices, late dinners and hitting the gym at night time, increases this hormone in the evening. The normal cortisol curve is should look like this; high in the morning, a few spikes during the day and a low slope in the evening. An upside down curve is the promoter of coffee consumption. We found in this amazing beverage the holy grail of our night life. The ability to think straight in the morning, pick ourselves up and move on, makes the society we live in functional.
As we wake up we miss the morning sun spectrum as we spend our mornings inside or running off to our daily jobs. This is affecting our circadian cycle. When this cycle is affected the AM cortisol level is low. Artificial light in the evening is rising up cortisol which makes us quite active. Many of us even go to the Gym to release this energy boost. This is how we develop a upside down cortisol curve. Coffee is giving us a hand in the morning replacing that blue shade before sunrise. This light is the real activator of the rise of the cortisol level. It hydrates and helps putting more water in between the nerves and glial cells in the brain engaging the waking process. The caffeine is the cherry on top in this entanglement. Despite of the common conception, caffeine is not the reason of our sudden rise. It stimulates endorphins and adrenaline after CGA already hydrated the brain. This is combination wins against any caffeine only soft drink. In our modern world we have found a good friend in coffee, a nice trick that covers an underling issue with our circadian cycle.
The takeaway
A poor hormonal panel starts with upside down cortisol levels. If you cannot make it without coffee in the morning now you know why. It’s good to bring this up to your physician and get tested on saliva cortisol level. This package has at list two up to four tests to take home. It will show your daily cortisol curve. Why is this important? This hormone steals from the other steroidian hormones like estrogen, testosterone and progesterone. It can upregulate your thyroid production of T4 initially and raise cholesterol. These two are needed for hormonal production. As we can see needing coffee in the morning can hide ugly things. Keep an eye open for these sorts of needs that are just another demand created by our social life interacting with human biology.
