How does drinking coffee affect the level of hemoglobin in the blood — does it raise or lower it?
Heart and vascular health, proper functioning of blood flow, blood circulation processes and sufficient hemoglobin levels are indispensable conditions for a full life.
All processes occurring in the body directly depend on the state of the cardiovascular system. The condition of the heart valve and the walls of blood vessels determines the possibility of a normal and sufficient blood supply to human organs, systems, tissues and limbs.
By determining the level of hemoglobin, in turn, it is diagnosed to what extent the chemical composition of the blood allows oxygen to saturate organs, tissues and body systems.
The state of the cardiovascular and circulatory systems, hemoglobin levels are influenced by many factors, among which two groups should be distinguished:
- External (ecology, stress);
- Internal (nutrition, water consumption, presence or absence of bad habits, regular exercise, breathing, genetic conditioning).
The impact of external factors for the most part does not depend on the will of a person. Internal factors turn out to be almost completely controlled and regulated.
Currently, there is still debate about the effects of coffee on the circulatory system.
Consider how a coffee drink affects the cardiovascular system and the level of hemoglobin in the blood. Does he raise his level or, conversely, lower it?

How does the drink affect hemoglobin?
The main charm of coffee, which determined its popularity, is giving the body energy. The redistribution of energy in the human body is caused by a special fermentation of coffee, through which the process of assimilation of iron by the body slows down.
According to one study, mothers who regularly consume coffee had a slightly lower iron concentration in breast milk compared to those who abstained from taking coffee. This contributed to a decrease in hemoglobin in newborns and increased the risk of anemia. It was concluded that coffee really "leaches" iron from the body.
Meanwhile, iron deficiency in the body is one of the main causes of low hemoglobin levels. This is the stable relationship between coffee consumption and hemoglobin levels in the blood &8212; with coffee consumption, it decreases .
Prolonged iron deficiency exacerbates the situation of an anemia sufferer (a condition corresponding to low hemoglobin levels in the blood).
The development of this condition can lead to undesirable problems such as:
- Deterioration of hair and nails;
- Weak potency in men and menstrual disorders in women;
- Pallor of the skin, puffiness;
- Deterioration of the skin condition;
- Fatigue , accompanied by shortness of breath and fainting;
- Anorexia.
Is it possible to drink it with low hemoglobin? It should be noted that although a reduced hemoglobin level may not be associated with a lack of iron, nevertheless, coffee consumption, one way or another, it aggravates the condition . So, given the mechanism of coffee's effect on the body, it is better for people suffering from a low hemoglobin content in the blood to give it up.
At the same time, there are other mechanisms effects of coffee on the cardiovascular system and blood, some of which should be classified as positive, others as negative.
How else does coffee affect the body?
As for the negative effects, except for the detrimental effect on the hemoglobin content in the blood, coffee can stimulate the following processes :
- Prolonged pressure increase;
- Excessive stimulation of the nervous system during abuse;
- Leaching of calcium, magnesium and potassium from the body;
- The development of varicose veins.
On the other hand, coffee, provided it is consumed correctly and moderately, can have the following effects on the body positive actions:
- Improvement of the patient's condition during attacks of hypertension;
- Improvement of blood circulation ;
- Stimulation of the endocrine and digestive systems;
- Performance improvement by stimulating the central nervous system;
- Replenishing the deficiency of a certain group of nutrients.
In addition, according to the results of clinical studies, the consumption of natural black coffee without sugar can stop the development of substandard formations and increase hemoglobin levels.
Daily allowance and rules of use
The difference between a drug and a poison is in dosage. Therefore, even with good indicators of hemoglobin levels in the blood, caffeine lovers should exercise restraint and caution. Do not forget about the consumption rate and the distribution of this rate throughout the day.
Experts recommend drinking no more than 3 cups natural black coffee without sugar during the day, and give preference to drinks such as espresso and ristretto.
Their advantage over Americano, cappuccino, etc., is due to the chemical properties of caffeine. Caffeine is distributed throughout the entire volume of the drink without taking into account the strength. In other words, ristretto, despite the fact that it is the strongest of the traditional coffee drinks, will affect the body milder than its more voluminous and seemingly gentle counterparts.
To avoid sleep problems, it is not recommended to drink coffee after 6 p.m. Besides, you should not drink coffee on an empty stomach. Read also, what can replace coffee for cheerfulness .

Conclusion
Thus, although an invigorating drink reduces hemoglobin levels by blocking iron absorption, moderate and responsible consumption of this traditional drink in the absence of direct contraindications can still bring very tangible benefits.
In addition to moderate coffee consumption, in order to restore and maintain the health of the cardiovascular and circulatory systems, it is important to give up bad habits, not be influenced by stress, put food in order, saturating it with useful products. First of all, we are talking about lean meat, fish, olive and linseed oils, fruits, berries, herbs and vegetables, green tea.
