Coffee is the most popular stimulant beverage worldwide. The drink that helps billions of people start their day and be productive is known to have complex effects on the body beyond simple energetic ones. There is an abundance of studies focused on the relationship between cortisol and coffee because the hormone is involved in various processes connected with awakening and stress responses.
Thus, does coffee raise cortisol levels? To understand the relationship between cortisol and coffee, let us see what effect the beverage causes and how this effect affects your body. Below, you will find the information about how coffee changes cortisol levels and what the main advantages of coffee are for the body, if consumed properly.
Does Caffeine Raise Cortisol?
In general, yes, it does. Does caffeine raise cortisol? Yes, coffee increases the activity of the hypothalamic-pituitary-adrenal axis that stimulates the adrenals to release the cortisol hormone. Caffeine has stimulating properties, and thus activates the central nervous system and starts HPA activity.
Nevertheless, the impact of caffeine depends largely on the frequency of consumption by a person. If someone rarely consumes coffee, even one cup can lead to a considerable elevation of cortisol levels. Habitual consumption of the beverage is followed by adaptation of the body, making the impact of coffee weaker, although not absent.
This effect can become more obvious when drinking caffeine on an empty stomach and during stressful periods or morning hours when cortisol levels are high enough. During these hours, coffee only adds to the existing high concentration of the hormone in the body.
Coffee and Cortisol: What Happens in Your Body
After having been absorbed into the blood, caffeine blocks adenosine receptors responsible for tiredness in order to stimulate the activity of the brain, adrenal glands, and the whole organism. As a result, the adrenals start releasing cortisol, which is a hormone responsible for alertness and energy mobilization.
In small quantities, cortisol can positively influence human health because it provides extra energy, stimulates reactions, improves mental functions, and supports quick responses of the organism. However, there is a point at which coffee increases cortisol: frequent coffee consumption can cause cortisol levels in the body to become too high, leading to excessive fatigue and an inability to relax.
This explains the link between cortisol and coffee, as well as why caffeine can affect stress levels differently depending on the time of day. In the morning after a good sleep, a person experiences positive effects of the drink, whereas in the case of lack of sleep and stress, coffee triggers negative reactions such as agitation and nervousness.
Moreover, in order to provide you with the possibility to experience a relaxing and concentrated state, it is necessary to take care of the nervous system by using appropriate supplements. Explore HappyMynd for more details about the beneficial ingredients.
Health Benefits of Black Coffee
We should note that even though the issue of coffee and cortisol is rather problematic, there is no need to stop using the beverage. The health benefits of black coffee are great and proven, provided that you consume it in moderate amounts.
Black coffee is an excellent source of antioxidants and anti-inflammatory compounds that contribute to the reduction of oxidative stress and improvement of the cardiovascular system. Regular use of moderate amounts of black coffee helps prevent various diseases, including fatty liver disease, type 2 diabetes, and other conditions, among which are neurodegenerative disorders.
The cognitive effects of coffee are also worth mentioning since caffeine enhances memory capacity, reaction speed, and concentration. Moreover, the beverage can mildly improve the mood and motivation of a person and provide light metabolic activation.
Of course, you should not rely upon black coffee as a tool for improving your health. The problem consists of ignoring basic things such as sleep, hydration, and nutrition.
How to Drink Coffee Without Spiking Cortisol
If you don’t want to suffer from stress caused by excess cortisol, or if you’ve been asked, “Does coffee raise cortisol levels?”, here are a few tips to help you avoid unpleasant situations and give a clear answer:
-
Do not drink coffee immediately after waking up because your body experiences a peak of cortisol secretion in the morning. Wait 60-90 minutes after getting out of bed.
-
Do not drink coffee on an empty stomach. Always pair coffee with a healthy meal containing proteins and fats to reduce cortisol spikes and stabilize blood glucose levels.
-
Remember, when coffee increases cortisol, limit your caffeine consumption to 1-3 cups daily. Stop consuming the beverage early in the afternoon to protect yourself from insomnia.
-
Take into account possible stressful factors that may trigger additional secretion of the cortisol hormone by your body. Reduce the amount of coffee in this period.
-
Stay hydrated all day long. Make sure you get enough magnesium and B vitamins that help restore your nervous system after each cup of coffee.
