Coffee is the most common drink in the world. Many people without a cup of drinking simply cannot start working, because the drink is invigorating and energizing. Use is not limited to morning intake, most continue to drink it throughout the day. Today, its beneficial properties are known to prevent many diseases. Early experiments revealed a negative effect on normal pressure and the cardiovascular system. Consumers interested in the question of whether coffee raises or lowers blood pressure?
Recent experiments have highlighted the positive and negative aspects of the drink. The type of its influence depends on the individual reaction of the organism.
Sometimes he is able to lower blood pressure, may exercise the same effect as an energetic - gives strength and helps to wake up, and in some situations has a completely different effect - people become lethargic, they want to sleep.
As a drink affects the pressure, no one will guarantee, because the research on this topic should be prolonged, not short-term.
When drinking, you can observe the following effects:
- a person without diseases, changes in pressure will not feel;
- hypertension can be a factor in high blood pressure. hemorrhage will be the decisive consequence;
- only a small part of consumers (20%) feel a drop in pressure;
- regular use provokes the body's adaptation to the effects of the drink.
From the experiment, we can conclude that coffee, with reasonable use, does not affect the intracranial pressure.
If you drink large doses, an excess of caffeine will affect all body systems. A one-time drink increases the pressure. The hypertensive effect will be short - only up to one and a half hours. The duration of this action is different for each, it depends on the features. Indicators can increase by 8 values, just because of a cup of drink. Hypertension is not able to manifest itself in healthy people under its action. The body is not able to respond to increased levels of caffeine, due to adaptation to its intake.
How does coffee pressure?
Consumers are actively interested in - is it possible to drink coffee with elevated pressure? First you need to understand how the substance affects the human body. Caffeine is found in many foods, but in tea and coffee it is more pronounced. Despite the pathway into the blood, the pressure rises in any situation. This is due to active stimulation of the CNS. When feeling tired, it is used very often. It stimulates brain activity, so it is drunk to activate mental work. Due to vascular spasm, the pressure rises.
Adenosine is a substance synthesized by the brain to reduce human activity by the end of the day. It gives the ability to rest and sleep normally. Healthy sleep is restorative, after a hard day. The presence of a substance makes it impossible to stay awake for several days without rest. Caffeine also suppresses this substance, because of this, a person cannot fall asleep normally, adrenaline rises in the blood. For the same reason, pressure numbers increase significantly.
Recent studies prove that if you regularly drink black coffee, the pressure value will be above the norm, if it was previously within it. Most cases are associated with a tendency to hypertension. In a healthy person, the indicators will rise rather slowly. It has been proven that it is precisely three cups of drink that can enhance it.
Regarding the decline in indicators, there are data - only 20% of people feel the reduction in pressure after drinking a drink.
According to modern research, coffee and communication pressure do not have. The body quickly adapts to it, regardless of the amount used. If he does not respond to an increase in the amount of caffeine, then the pressure remains unchanged, but it has been proven that drink lovers are more likely to experience hypertension.
Due to the individual characteristics of the organism, there is no unambiguous reaction to coffee. This is influenced by many factors - the ability of the central nervous system, genetic propensity and the presence of other diseases.
There is a definite answer to the question of whether it is possible to drink coffee with elevated pressure.
With hypertension, it is desirable to refuse coffee. If it is possible to reduce consumption to one cup, the fact is that such an innocent drink can be harmful.
To leave fatigue, you need to drink natural coffee, it has great advantages than instant coffee. Moreover, it is perceived by the vessels much better and the reaction to it will be calmer.
To prevent the drink from harm, you need to follow these tips:
- in case of hypertension, the amount of drink consumed should not exceed two cups, then it will not bring harm;
- it can be used by healthy or low-pressure people;
- at night it is advisable not to drink a cup, especially for people with insomnia, the optimal time for coffee is morning and lunch, as a last resort, you can drink after dinner;
- if the body is tired, then the coffee will not help him, you can replace it with a good rest, because the drink will only increase the load on tired organs and systems.
There are situations where hypertensive patients should not take coffee. In such cases, an ambiguous reaction occurs, and well-being can deteriorate sharply.
It is forbidden to drink coffee in such cases:
- if the person is in a stuffy room;
- under the influence of the hot sun;
- in the period "before" and "after" physical exertion;
- in a stressful situation;
- after hypertensive crisis.
This is more true for coffee consumers, who rarely drink it.
Many hypotonics ask: does coffee reduce or increase blood pressure? A low arterial indicator causes a cup of drink to drink. This, in their opinion, solves the problem.
One cup can only increase it for a couple of hours, so they resort to several batches in the hope of a steady increase in performance.
For people with low blood pressure, this dosage is very risky, because under the influence of substances, the heartbeat is greatly accelerated. At this rate, you can cause tachycardia, and then other diseases of the cardiovascular system.
Given the rapid addiction of the body, a few cups, soon, will be missed to increase.
After that, we can draw one conclusion - coffee for the treatment of hypotension is absolutely not suitable. Its action increases the performance only for a few hours, after which there is a need for an additive. Use it in this state can be, but a little.
The recommended dose for coffee lovers is two cups per day. This number will not cause any pathological changes.
An increased amount can lead to pathological changes in the cardiovascular system. If you feel unwell, you should see a doctor.
It can not be argued that regular intake of coffee will not affect the body.
It is one thing if the quantity is within the limits of a reasonable one, and another when the person is abusing the drink. Sometimes people are able to exceed the maximum allowable dose by several dozen times.
From overuse of coffee, there are cases of overdose.
If a person has used it in large quantities, can expect the state:
- increased irritability;
- visual impairment, increases the likelihood of developing diabetic retinopathy;
- muscle tremors;
- muscle stretching;
- involuntary muscle contraction;
- rapid breathing;
- rapid breathing;
- pain in the abdomen.
This is not a complete list of pathological phenomena of overdose.
The slightest manifestations should be the reason for seeking medical attention. Increased consumption of coffee can accelerate the development of heart disease with regular use.
Coffee has a diuretic effect, is able to load the kidneys and cause mild dehydration. The body reacts to adrenaline with heartbeats, vascular spasms, etc. It is especially important for coffee lovers to undergo regular checkups. If a person consumes a large amount of drink, he must pass the examination.
You need to be careful about coffee for people with type 2 diabetes. There are myths about the effect of the drink on the body.
Some of them are unjustified, since the experts have refuted their veracity:
- The color of the tooth enamel changes from coffee. This is a lie, because enamel is not influenced by coffee.
- Coffee increases the pressure. The body has an individual reaction to caffeine, so it can not be argued.
It should be remembered who can not drink coffee.
During pregnancy, excessive leaching of calcium damages the fetus. It is forbidden to use the drink to people with ailments from the gastrointestinal tract. In such circumstances, it can provoke an ulcer, pancreatitis, gastritis, increased blood pressure, dizziness, vomiting, nausea and severe headaches, tinnitus and impaired cognitive processes.
