Caffeine sensitivity can cause symptoms such as anxiety, irritability, and muscle tremors, and can vary in severity. Caffeine intolerance includes all the symptoms of sensitivity but with greater severity, and can also cause skin rashes and seizures. Caffeine intoxication can occur with excessive consumption and can lead to caffeine poisoning. The best way to treat sensitivity is to reduce or eliminate caffeine consumption.
Many people consume caffeine one or more times a day to increase mental focus and improve energy, although this common stimulant can cause adverse effects for some. Caffeine sensitivity is a condition in which a person develops symptoms such as anxiety or irritability after consuming caffeine. The severity of sensitivity can vary from individual to individual. Some people are very sensitive to even small amounts of caffeine, while others can ingest large amounts without feeling any ill effects. Caffeine is found in coffee, black and green tea, and many cola products.
The most common symptoms of caffeine sensitivity are anxiety, restlessness, and irritability that range in intensity from mild to severe, depending on the person. The most painful symptoms include muscle tremors, irregular heartbeat and nausea. Caffeine headaches are another common symptom of caffeine sensitivity. Although caffeine is a stimulant, some people experience fatigue after consuming caffeine-containing beverages or products. Caffeine can also disrupt sleep, causing difficulty falling asleep and less restful sleep at night.
While caffeine sensitivity is fairly common and often causes only mild symptoms, some people have a more severe caffeine intolerance and experience severe adverse reactions to even small amounts of this stimulant. Caffeine intolerance includes all the symptoms of caffeine sensitivity but with greater severity. Additional symptoms, though rare, include skin rashes and seizures.
Caffeine intoxication is another symptom of caffeine sensitivity and excessive consumption of products containing caffeine. This condition is associated with consuming large amounts of caffeine over a short period. Often, 250 mg of caffeine consumed within a few hours can lead to caffeine poisoning. Caffeine poisoning includes symptoms associated with caffeine intolerance and sensitivity. In addition, rambling speech, long periods of inexhaustibility, and a flushed face can occur.
People who don’t regularly drink coffee or caffeinated beverages are typically more susceptible to experiencing symptoms of caffeine sensitivity. Other factors that may contribute to the likelihood of a symptomatic response include stress, body weight, and smoking. Those who have been diagnosed with a nervous disorder are also usually more prone to symptoms. Interestingly, men appear to be more likely to have a sensitivity to caffeine than women.
The best way to treat caffeine sensitivity is to reduce or eliminate caffeine consumption. Many products such as chocolate, tea, coffee, cola and desserts contain caffeine. Most energy drinks also rely on high levels of caffeine as a stimulant. Even decaffeinated coffee and tea can contain small amounts of caffeine.
