How Much? Best dose seems to be a couple of regular cups a day – one in the morning and one in late afternoon. It is the perfect amount to keep you alert and concentrated, lift your mood and rev up physical endurance. Five cups a day to more could mean trouble and nighttime coffee is verboten for people with insomnia.

Let’s see some myths and cautions that we should know between coffee and certain health concerns over the years of studies.

Coffee and Blood Pressure

Contrary to popular opinion, moderate coffee drinking (less than 6 cups a day, according to a study) does not contribute to long-term high blood pressure, except in smokers. Combining caffeine and smoking can significantly drive up the blood pressure of those already suffering from the disease. In others, coffee does commonly raise normal blood pressure but only temporarily. Apparently, the body usually adapts to the caffeine in a few days.

If you already have high blood pressure, Vanderbilt University researchers see no lowering effect from giving up caffeine or coffee. And people with high blood pressure who don’t drink coffee don’t live longer, according to research at the University of Texas Health Sciences Centre.

High Blood Pressure

Coffee and Heart Disease

heart disease

Heavy coffee drinking seems to promote heart disease. A major study at John Hopkins University School of Medicine found that men drinking 5 or more cups of coffee a day were almost three times as likely to develop heart problems as non-coffee drinkers. Women, too, who drink 6 cups of coffee a day suffer two and a half times as many heart attacks. Coffee can raise blood cholesterol slightly in some people, but that seems to be a minor problem for most, according to a review of twenty-two international studies. However, some experts advise: if your cholesterol level is very high, cut out coffee for a month and see if it goes down.

Coffee and Ulcers

Coffee is known to stimulate gastric secretion, so is considered damaging to ulcer patients. However, one recent large-scale Swedish study found no connection between coffee drinking and development of gastric or duodenal ulcers.

Note: Decaffeinated coffee also spurs production of stomach acid, so apparently caffeine is not the culprit.

Coffee and Anxiety and Panic Attacks

Undeniably, caffeine can trigger panic attacks in some susceptible persons, primarily women; panic attacks if allowed to continue can lead to full-blown agoraphobia (fear of leaving home). As little as 2 cups of coffee a day have induced panic attacks, and even one cup can produce noticeable symptoms. It is advisable that cutting out caffeine if you are vulnerable to panic attacks. Apparently, some person are ultra sensitive to the central nervous system effects of caffeine.

Coffee and Sleep

If you want to sleep quickly and sleep well, don’t drink coffee before going to bed – or much after late afternoon, according to some experts. Caffeine can prolong the amount of time it takes to go to sleep, total amount of sleep and produce fewer periods of deep sleep. Lots of studies show that your brain wave changes in response to caffeine. Coffee drinking in excess can cause “restlessness, anxiety, irritability, agitation, muscle tremor, insomnia, headache, sensory disturbance, diuresis, cardiovascular symptoms and gastrointestinal complaints.

However, of course, everyone has different experience when drinking coffee. Bare in mind that we should drink it in moderation to prevent overdosing or causing any harm to our body.
