Popular issues are often surrounded by half-truths and completely false statements. Unfortunately, medicine is no exception. The information regarding health problems is overflowing with false and outdated information. As a result, even some doctors who are not up-to-date, may harbor some false opinions.

In this article, we will unveil some of the popular myths and half-truths regarding the circulatory system in order to ensure that our readers know what is good for the heart and what is not.



There is a common misconception that salt can cause heart problems, namely hypertension. This myth is so wide-spread due to the fact that doctors themselves believed it to be true until recent research has revealed that there is no correlation between the salt intake and the development of hypertension.


Some people who travel quite often have to go through time and climate zones and feel no ill effects. Others, to the contrary, even when they are lying on the sofa at home, can feel the slightest changes in the atmospheric temperature and pressure which results in feeling unwell and tired. Such sensibility to changes of weather conditions is called ‘weather sensitivity’ or ‘meteosensitivity’.

Weather-sensitive people, or, as they are often called, human ‘barometers’, are mostly those who suffer from joint diseases or cardiovascular disorders, those who often work long hours, those who have not enough rest and overwork themselves. Such groups of people include patients with the heart, brain or lower extremities atherosclerosis, patients with respiratory or musculoskeletal diseases, highly allergic individuals and those who have neurasthenia. So there is no doubt that weather does affect human health. There is even a certain field of science called biometeorology which studies the interactions between living organisms and the processes happening in the atmosphere.


Diabetes is major problem worldwide but especially in the United States. The number of people with diabetes is rapidly growing, although the rate at which this is happening has slightly decreased. The National Diabetes Statistics Report (released on June 10, 2014) has shown that the annual incidence of diabetes has decreased from 1.9 million of new diagnoses per year in 2010 to 1.7 million in 2012.

Nevertheless, the percentage of people affected by diabetes in the United States in 2012 was 9.3%, while the percentage of people with pre-diabetes was 27.5%. This is a huge number, considering how this condition damages a person’s health, even with the necessary treatment. Naturally, the circulatory system is one of the first things that is greatly damaged by elevated levels of sugar in the blood stream.


It is a well-known fact that women tend to live longer than men1. We may ask what is the reason for this? Of course there are many factors at play. One of the main reasons for the longevity of women is something that makes women uniquely women. That 'something' is estrogen, the main female hormone. There is actually a whole group of estrogens, which include:  estrone, estradiol, and estriol. Estradiol is the predominant estrogen that circulates within the bloodstream during a woman's reproductive years;  estrone is the main estrogen in women experiencing menopause;  estriol is the estrogen present during pregnancy.


Life in a big city is hectic with everyone hurrying somewhere, always being late and getting stressed due to the lack of time. This causes people to sleep much less than the necessary 8 hours a day which leads to a number of health risks.

A lot of articles online claim that lack of sleep causes various cardiovascular diseases. But is this true? And if it is true, why does this happen?

benefits of coffeeAt times, we all feel sleepy, tired, and devoid of energy - right after getting up in the morning, in the midst of all-night studying for the exam, or during an especially stressful day at work.  A cup of coffee or an energy drink seems like a great way to boost that energy level. And that’s what most people do – they drink coffee and energy drinks to keep them awake and alert and then those drinks become a part of their lifestyle. In fact, coffee has become one of the most popular drinks in the world and an irreplaceable part of the day and daily routine. Some people drink a single cup to wake up in the morning, while others drink cup after cup all day and their daily consumption could be as much as five or six cups.  It is not surprising that people have started to worry that drinking coffee and energy drinks may be dangerous for the heart.  The debate over whether coffee and energy drinks are safe has been raging for years. Here are both sides of the story.


The term “varicose veins” most commonly refers to the veins in the lower extremities because such veins mostly develop in legs, but actually they can occur elsewhere. According to the statistics, varicose veins affect about 55% of women and 45% of men. About 50% of the patients suffering from this condition have inherited it. If both of your parents have varicose veins, then your chances of developing this condition are close to 90%. In the case of one parent affected, the chances of a daughter are about 60%, and those of a son – 25%.




Factors that influence the development of this predisposition:

    • Lifestyle. The risk group includes people with occupations that require them to stand or sit long hours, like hairdressers, drivers, software engineers, etc.
    • Clothing. Vascular spiders may appear at any age. Those people who prefer tight jeans are at a greater risk because tight clothes form a kind of a venous tourniquet – the arterial blood can pass easily, but is much harder for the venous blood to return.
    • Pregnancy. Varicose veins appear as a result of hormonal changes, decrease in collagen level and increase in intra-abdominal pressure.

How to recognize the disease?

red-heart-computer-mdnMost young and middle-aged people nowadays are working in offices equipped with computers and laptops. These people spend a tremendous amount of time on their computers. And many people have either a laptop or a PC, or even both, at home. So once they leave work, they come home and relax in front of the monitor – watching movies, listening to music or just socializing via Facebook or other social networks.

The average citizen of any developed country spends up to 10 hours per day on the computer. And it’s the body and internal organs that have to pay for such lifestyle. For example, sitting too long at a computer can provoke the development of various cardiac problems.  


What is the driving force behind our lives? Certainly, exercise is one of the things that come to mind. Not only does it allow us to lose weight and stay fit, but it also has numerous other health benefits. Cardio exercises and weight training are two major groups of exercises, which develop your body in different ways. The main focus of weight training is building strength, building muscle mass and shedding a few calories in the process. Cardio on the other hand is the preferred method if you wish to lose weight and build your endurance. Both types of exercises are very important and should be used in conjunction. However, this article’s main focus will be cardio exercises.

So, what exactly is cardio?

Cardiovascular training, otherwise referred to as aerobic training, is exercise that raises one’s heart rate and improves blood circulation. Some of the most common forms of cardiovascular exercise are power walking, jogging, swimming, cycling, and many others.

Heart disease is not just one condition but a combination of several different conditions that negatively impact the heart. Most heart diseases are referred to as cardiovascular diseases. These involve blocked or narrowed arteries that often lead to heart attacks or stroke. However, there are other heart conditions which are also be referred to as heart disease  and which negatively impact the heart - rhythm, myocardium, valves, and other parts of the heart.

STREPTOCOCCUS-PNEUMONIAEBacterial pneumonia is an infection that affects one or both of the lungs. It creates an inflammation of the alveoli (the lung's air sacks) and causes them to fill up with cellular debris, pus, and fluid. This makes it more difficult for the body to turn oxygen into carbon dioxide. The most common symptoms of bacterial pneumonia are pain while breathing and breathlessness. Bacterial pneumonia can be mild or very serious. A severe case of bacterial pneumonia can even cause respiratory failure and death. Unfortunately, those are not the only risks and dangers that bacterial pneumonia creates. Recent studies have shown that bacterial pneumonia can do serious damage to the heart.
