Unaccounted cups to tea and coffee can cause anxiety, nervousness and jitteriness
Most people across the world drink tea or coffee for their daily caffeine fix. According to experts, even though caffeine is generally considered safe in low to moderate amounts, high levels of consumption can lead to unpleasant and even dangerous side effects.
Doctors say caffeine boosts your mood, metabolism, and mental and physical performance, and you can safely consume 400 mg of caffeine without associated negative effects. However, if you are consuming too much or extremely high doses, it may have unpleasant and even dangerous side effects.
Here are a few side effects of too much caffeine in your body:
Spikes anxiety
Caffeine is known to increase alertness by blocking the effects of adenosine, a brain chemical that makes you feel tired. However, it also triggers the release of adrenaline, the hormone associated with increased energy. And so, if you take extremely high doses of coffee or tea, the effects can lead to anxiety, nervousness, or jitteriness.
Causes insomnia
Caffeine has a remarkable ability to make you stay awake for a long time. However, drinking too much can also make it difficult to get enough restorative sleep. According to studies, higher caffeine intake increases the amount of time it takes to fall asleep while also decreasing total sleeping time.
According to doctors, regulated and uninterrupted sleep is extremely important for your overall health.
Causes digestive issues
For many people, morning coffee helps get their bowels moving as it is a known laxative. However, it also releases gastrin, a hormone produced by the stomach that, in large quantities, can lead to diarrhoea. Since coffee can have major effects on digestive function, you may want to cut back on the amount you drink or switch to tea if you experience any issues.
High blood pressure
While caffeine does not increase the risk of heart disease or stroke in most people, it does raise blood pressure levels because of its stimulatory effect, which happens when ingested in large quantities.
According to experts, elevated blood pressure is a risk factor for heart attack and stroke as it can damage arteries over time, restricting the flow of blood to your heart and brain.
Causes frequent urination
Caffeine also causes the problem of increased urination as a side effect of high intake due to the compound’s stimulatory effects on the bladder. Studies have time and again proved the association between a wet, overactive bladder and high caffeine consumption.
If you drink a lot of caffeinated beverages and feel that your urination is more frequent or urgent than it should be, it may be a good idea to cut back on your intake to see if your symptoms improve.
Rapid heart rate
High caffeine intake can also make your heartbeat faster, leading to atrial fibrillation—reported in young people who consumed energy drinks containing extremely high doses of caffeine.
