Coffee, Stress and Tension
Drinking coffee can promote the release of the stress hormones cortisol, norepinephrine and epinephrine. These chemicals can increase your heart rate of your body, tension levels and blood pressure.
We tend to associate coffee with a boost but for many of us this is a kind of jittery tension. Turning on the stress hormones with coffee when you are eating also interferes with the digestive process.
Caffeine in coffee is well-known to interfere with GABA metabolism. The neurotransmitter, gamma-aminobutyric acid that is involved in regulating mood it has a calming effect on the gastrointestinal tract.
