If someone consumes enough caffeine over certain a period of time, their body can become dependent on it, says Worley. Symptoms of sensitivity to caffeine include a racing pulse, headaches, jitters and even insomnia,” Worley breaks down.ħ. 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. “Everyone’s body interacts with caffeine differently based on a variety of factors. 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. They may feel as if they've had five or six cups of espresso after drinking only a few sips of regular coffee. Per Rissetto: “Some people can be more sensitive to caffeine than others. “Weaning yourself off of caffeine and then reintroducing it later may help,” says Worley.Ħ. So that lightening jolt of energy you used to get after your first espresso doesn’t hit the same now that you take two shots a day. And keep an eye out for coffee beans that look discolored or shriveled.ĭrinking lots of coffee on the regular?

To avoid this mold, try to diversify the coffee you drink, whether that's changing up coffee shops or buying different brands. Mycotoxins have been linked to causing chronic fatigue. Moulds that can produce mycotoxins grow on numerous foodstuffs such as cereals, dried fruits, nuts and spices.” Eek.
However, studies show that caffeine contains mold called mycotoxins, which according to the World Health Organization are “are toxic compounds that are naturally produced by certain types of moulds (fungi). This also applies to super sweet creamers and energy drinks with long lists of other ingredients.Įw. “If you load your coffee up with sugar and sweeteners, when that wears off you can get a sugar crash and again feel pretty tired and sluggish,” Rissetto reminds us. If you fall into the latter camp, you might be feeling exhausted after drinking your morning joe because of what you’re putting in it. There are two types of people in this world: People who take some sugar in their coffee and people who take some coffee with their sugar. When the caffeine inevitably wears off, you’re left with an adenosine buildup which makes you feel even more tired.” But-there’s a twist! “Just because our brain is no longer processing the adenosine doesn’t mean it stops producing it. So, when caffeine binds to those adenosine receptors, it stops our brain from feeling tired.
When caffeine hits our brain, Worley explains, it adheres to your brain’s adenosine receptors. Says Rissetto: “If you're drinking caffeine in excess of three cups or more a day, it can make you go to the bathroom more, causing dehydration which can make you feel dizzy and sleepy.”Ģ. Excess caffeine blocks adenosine receptors
How many cups of coffee, cans of Red Bull or pots of tea are you having a day? More than three?

Let’s take a look. “Not crazy at all,” Vanessa Rissetto, MS, RD, CDN and co-founder of Culina Health assured me. What gives? Does caffeine really make some of us sleepy? Or am I crazy? But I swear, sometimes a mid-day cold brew actually makes me feel more ready for a nap than anything else-forget about feeling wired. By definition it shouldn’t make a person tired.
