If you belong to those who will never skip morning coffee, you may have a good reason, according to Dr. Yaron River, director of the neurology department at Hillel Yaffe Medical Center, “The caffeine was given a” name “of addictive rather than positive substance. So it is true that there is coffee and caffeine consumption from addiction, but it is important to understand that caffeine has a few beneficial effects. The evidence is that the pharmaceutical industry is using it to strengthen the action of one bullet or another. ”

Caffeine is good, caffeine is bad

The action of caffeine in the body is such that it binds to the receptors of a substance called endosine. It is a natural material in the human body, which serves as the most important building block for energy to produce various chemicals, including nucleic acids, DNA and RNA. The result of blocking then endosine by caffeine is such phenomena as encouraging split attention, increased alertness, increased heart rate, diuretic effect, anti-inflammatory effect, decreased swelling, mild shrinkage of the blood vessels within the brain, reduction of malignancy to colon cancer. “The less positive results,” explains Dr. River, “are that they have a negative effect on people with high blood pressure. For them, increased caffeine consumption may be problematic. ”

If we go back to the morning coffee that we forgot to drink and the headache that we have – when we consume caffeine regularly – we increase the amount of receptors to endosin, and the result is that the natural substances in the body that binds to them allow over-transmission of pain signals and also lead to excessive expansion of the intracranial blood vessels. Such expansion is in itself a source of throbbing headache. That is, from the moment we put the centers of pain in the brain into caffeine at a certain amount and at a certain time, its absence creates a condition that allows the transfer of pain. In a simplistic formulation: Not drinking coffee can cause a headache. It is a low-intensity bronchial pain that often goes on in 20 minutes with a cup of coffee (one cup of coffee has 150 milligrams of caffeine – a dose that has an effect on brain pain centers).

“People come to the clinic with complaints of headaches at the end of the week, when they do not have any emotional or physical pressure that can cause them headaches,” says Dr. River, “when I check their ‘coffee routine,’ it turns out that on Shabbat They give up the morning coffee for various reasons. I often ask them to keep one cup of coffee at least before noon, even on weekends and vacations, to reduce the frequency of headaches. ”


Avoid in principle 300 to 400 milligrams of caffeine a day. Pay attention to the consumption of other beverages that contain caffeine (energy drinks or cola). Consumption of two cups of coffee a day is reasonable.

People with high blood pressure or arrhythmias should be overly cautious about caffeine consumption. The amount of two cups of coffee is the most appropriate limit for these people, but in some situations completely avoid the consumption of coffee.

People who have asthma and take amniotic products (such as thiators) should also pay attention to caffeine consumption because the amenifilins belong to the same group of substances as caffeine. Using coffee in this condition can increase the risk of toxic effects (heart arrhythmias and seizures).

Have frequent headaches? Should be considered whether they are caused by excessive consumption or irregular consumption of caffeine and to consider cessation of coffee consumption.
