6. Your Body Reacts Differently to Caffeine
Per Rissetto: “Some people can be more sensitive to caffeine than others. They may feel as if they've had five or six cups of espresso after drinking only a few sips of regular coffee. People with this sensitivity metabolize caffeine more slowly, and their symptoms may last for several hours.” You may even metabolize caffeine in a dramatically different way based on your genes, says Worley. “Everyone’s body interacts with caffeine differently based on a variety of factors. For example, those with anxiety disorders may experience heightened negative symptoms when consuming caffeine, while for others, a few sips of coffee may feel more like several cups of coffee. Symptoms of sensitivity to caffeine include a racing pulse, headaches, jitters and even insomnia,” Worley breaks down.
7. You’re Experiencing Caffeine Withdrawal
If someone consumes enough caffeine over certain a period of time, their body can become dependent on it, says Worley. “If that happens and someone tries to suddenly and completely remove caffeine from their diet—what many call ‘going cold turkey’—they can experience a variety of symptoms ranging from headaches to fatigue to depression.” So, in this case, it’s the absence of caffeine that might be making you sleepy. If you’re trying to quit coffee and want to avoid the withdrawal symptoms, try the gradual approach: “Cut back on your consumption by ¼ of a cup every two to three days, or switch to green tea for less caffeine. Continue cutting back until you’re no longer consuming caffeine,” says Rissetto.
