What leads to caffeine sensitivity?
Caffeine sensitivity depends on our genetics. It is the structure of the DNA in our body that determines how much caffeine your body can process and metabolize. Whether you have a fetish for coffee, tea, cola, or chocolate, you’re actually consuming caffeine along with the other ingredients in these foods.
Caffeine forces the adrenal glands to produce stress hormones like cortisol and adrenaline. Although you may wake up and be alert due to this reaction, your friend may start to feel excessively nervous with a faster heartbeat. Many people take this medicine to increase their level of concentration. I know a friend who used to consume at least 2-4 cups of coffee a day to stay awake and study late into the night. She never felt any discomfort from caffeine consumption, but there are many that if they consume more than one cup of her favorite coffee they feel uncomfortable and literally shaken. They experience a rapid pulse, rapid breathing, and muscle tension. These people also feel restless, shaky, nervous, irritable, anxious, and restless at times.
For hundreds of years, this drug has stimulated a person’s mind and provided the extra energy needed to hunt animals for food. I once interviewed some athletes in my hometown who have a lot of good things to say about caffeine. They said they feel driven to do even better. However, a handful of them mentioned that consuming more than 500mg of coffee a day made their heart beat faster. Some of them also suffered from insomnia. However, multiple studies have confirmed one thing: Caffeine helps an athlete excel in performance and be successful.
Another very important aspect is that the more caffeine you consume, the higher your tolerance level will be. Naturally, those of you who prefer coffee over anything else will get more used to this drink compared to those who consume caffeinated beverages occasionally. As you continue to drink caffeinated beverages, your response begins to wane. According to experts, this is a normal process, as the body’s cells get used to this drug and respond less and less as more caffeine is consumed.
To get rid of all sorts of unwanted health problems, doctors say it’s best to control your caffeine intake. For example, ideally each human being should ingest only around 300mg per day. You should drink coffee, tea, or cola only when you need to be alert. For most people, the ideal time to consume caffeine is early in the morning to stay fit throughout the day.
Caffeine Sensitivity Levels
According to various research and data analysis, there are three levels of sensitivity to caffeine:
1. Hypersensitivity
2. Normal sensitivity
3. Hyposensitivity
You are highly sensitive to caffeine if you feel jittery, dizzy, begin to sweat excessively, or feel restless after immediate consumption of caffeine-enriched beverages or foods. Even consuming 100mg and less affects these people. Instead, you can enjoy a cup or two of green or black tea to keep you healthy and energized.
Normal sensitive people have no negative effects even after consuming between 200 and 400 mg (two to four cups) of coffee a day. However, if they consume more than 400 mg, they may develop insomnia, nervousness, increased heartbeat, and palpitations.
You have caffeine hyposensitivity if even after drinking more than 500mg of caffeinated beverages every day, you still feel strong without any health problems. You have no trouble sleeping pretty much any time of the day or night. However, you may experience a reaction, including apprehension, nervousness, upset stomach, vomiting, diarrhea, high blood pressure, etc. if you continue to use the medicine completely.
