A common symptom: a sign to quit morning coffee

If you experience recurrent headaches, you should avoid the morning coffee routine. Coffee acts as a kind of painkiller, but habitual consumption worsens headaches by impairing the body's natural pain defense mechanisms.

People with severe heartburn symptoms should also avoid it. Caffeine in coffee provides an alertness effect, but it also stimulates the secretion of stomach acid and gastric juices. Patients with gastroesophageal reflux disease or gastric ulcers may experience or worsen heartburn symptoms if they drink coffee on an empty stomach.

Meanwhile, caffeine can stimulate the sympathetic nervous system and cause various abnormal symptoms, even if it is not consumed in the morning. This usually occurs when coffee is consumed excessively, but people with 'caffeine sensitivity' can experience bodily changes even after just one cup of coffee.

Caffeine Side Effects Informing the Need to Stop Coffee

Headache, insomnia, irritability, tension, frequent urination or inability to control urination, rapid heartbeat, muscle tremors

If any of the seven symptoms occur frequently, it is advisable to stop coffee or switch to decaffeinated coffee.

People taking certain medications should also avoid coffee consumption. According to the Mayo Clinic in the United States, caution should be exercised when consuming coffee while taking medications containing ephedrine, theophylline, or echinacea. Ephedrine is used in cold medicines, theophylline for bronchial asthma, and echinacea for alleviating cold symptoms, all of which can increase the side effects of caffeine.

The general recommended daily coffee intake is less than four cups (400mg of caffeine). However, women who are pregnant, trying to conceive, or breastfeeding should consult with a doctor to limit their daily caffeine consumption to less than 200mg. This amount is equivalent to about two cups of coffee per day.
