Millions of people around the world drink coffee and tea and have done so for centuries. This means that you would probably be justified in wondering what might possibly be so unhealthy about drinking these world-famous drinks? These beverages aren’t bad in themselves, and in fact pose several benefits for the body. But they, like most things, can cause some serious problems when taken in excess. Caffeine, the primary chemical in tea and coffee, is a stimulant that affects the body’s nervous system. While small doses do good, making us highly alert and active, large doses exacerbate these very symptoms becoming counterproductive to our health. Therefore, it becomes extremely important to keep a watch on your coffee/tea intake. Research says that up to 4 cups (400 mg) is a safe quantity for adults. Read further to know more about why it is important to control your caffeine intake.

Increases Nervousness and Anxiety

If you are prone to anxiety attacks, then coffee and tea only add to the burden. Both are stimulants for the central nervous system and increase the secretion of stress hormones while also inhibiting the neurotransmitter that induces calmness. The increased stress levels, accelerate heart rate and cause high blood pressure that only worsens anxiety, making you jittery, restless and irritable.

Causes Muscle Twitch

Caffeine is a neuro-stimulant that provokes the body into heightened levels of awareness, sensitivity, and arousal. While a balanced amount can do good to productivity, too much can induce your body into short muscle spasms and twitches. Muscles are made up of fibers that are connected to the nervous system. While a little caffeine boosts your stamina, too much ends up confusing your nerve functions, in turn causing small muscle contractions.

Induces Insomnia

This is one of the most common symptoms of over-indulging in coffee or tea. One cup in the afternoon is enough to keep you up till night. The reason why caffeine has such a long impact on the body is that it takes almost 8 to 10 hours to be processed by the liver. This is why a small amount of caffeine can be handled by the body’s enzymes, but too much affects the body for a much longer duration, thereby disrupting sleep cycles. Recurrent disruption of sleep can easily turn into a more serious form of insomnia.

Causes Stomach Upsets

Too much caffeine is known to cause digestion related problems such as acid reflux and diarrhea. Caffeine contains laxative properties which affect the lowest bit of the colon that pushes out waste from the body. Caffeine is also highly acidic. Excess coffee relaxes the muscle sphincter between the stomach and esophagus (the sphincter is meant to stop backflow of digestive juices to the food pipe). Thus, the relaxation allows stomach acids to travel up into the esophagus, and burn the muscle lining, in turn causing what we commonly call – a ‘heartburn’.

If you ever experience any of these symptoms, then make sure to reflect on your caffeine intake as it could be one of the most ignored factors that can cause it. As caffeine can be addictive, make sure you gradually reduce your intake to ensure the least amount of withdrawal symptoms.
