A healthy person has a balanced of substances that maintain the tone of the vascular wall and keep it in a healthy state. But for people with a cardiovascular pathology, this balance is disturbed – vasoconstrictor substances are produced in excess and the production of vasodilator substances are lessened. Since adaptability is reduced, any stress, including climatic, causes unpleasant changes in the body of such patients resulting in high blood pressure, headaches and dizziness. Those with coronary heart disease may have more frequent attacks of retrosternal pains.

Summer heat


The best environmental temperature for the human body is 72°F (22 ºC). This temperature is recommended to be maintained in the room where a person sleeps. Sudden temperature changes are particularly dangerous for the health. At first the reserve forces of the body to help the heart work, but the resources are not limitless. That is why prolonged heat may worsen how a person with a weak heart and weather sensitivity feels. When it is very hot outside, people with heart problems experience an increase in heart rate and blood pressure, their peripheral vessels dilate, legs swell and the risk of blood clots becomes higher which leads to increased risk of stroke.

Here are some tips that could help you survive extreme summer heat:


  • Give up alcohol and coffee. Any alcoholic beverage, including beer, may promote rapid development of coronary vasospasm.
  • If you have any cardiac disease,do not stop taking the medicines prescribed by your cardiologist even if you think you feel better. Keep your sphygmomanometer close at hand so you can monitor your blood pressure.
  • Replenish the loss of fluid. Carefully choose what to drink – you need ‘right’ electrolytes; your preference should be fresh juices, green tea and water. If you like mineral water, then choose the one that contains minimum sodium salts. Give up sodas and do not have too many icy drinks and ice-cream.
  • Reconsider your diet – eat less meat and animal fats and more vegetables and dairy products. You should not overeat; the main rule is to have small and light meals.
  • When it’s too hot outside, doctors recommend staying in an air-conditioned room (or at least in a room with a fan) for as long as possible as well as avoiding the sun and excessive physical activity. However, in order to avoid hypothermia one should not sit, let alone sleep, under the air conditioner. Sudden temperature changes are very stressful for the vessels and the heart. When going outside, a person with a healthy heart can quickly adapt, but someone with heart problems may face heart rhythm disturbance and even develop heart failure.

Bitter winter frost


When it is frosty outside, the body may become too cold due to increased emission of heat. The combination of low temperatures, high humidity and high wind speed is particularly dangerous. Moreover, due to the body’s reflex mechanisms the feeling of cold occurs not only in the area of its influence but also in seemingly far body parts. For example, if your feet are frozen, then you will inevitably feel that your nose is frozen too and the feeling of cold will appear in your throat leading to the development of acute respiratory infections.

If a person notices any unpleasant vascular responses when going outside into frosty air, it is recommended to limit the time spent outside. It is even more important for those who have angina pectoris. In winter, there has been a sharp increase in the number of cases of preinfarction angina, hypertensive crisis and cold angina attacks. Frosty air may cause spasm of the arteries supplying blood to the heart - the vessels contract, blood circulation worsens and that leads to the formation of blood clots.

 Recommendations that help avoid the negative effects of the cold weather are as follows:

  • You should not go out from the warmth of indoors into the outside cold quickly – contrasting changes in temperature may cause vasospasm. It is better to stand for some time near the front door before you go out.
  • It is important to breathe through the nose – the air gets warmer while passing through the nose and throat which reduces the risk of a cold angina attack.
  • Do not forget to take the preparations prescribed by your doctor.
  • People suffering from high blood pressure are recommended to take valerian or motherwort tinctures in the morning and before going to bed and to thoroughly control their blood pressure.
  • People with ischemic heart disease should see a doctor to adjust their treatment.It is particularly important for those who take beta-blockers. Such medications may cause vasospasm of the extremities and cold weather is fraught with frostbite.
  • Those who have low blood pressure can start their day with physical exercise to stimulate blood circulation. Dark chocolate can also tone the body; carry it with you and occasionally eat several pieces.

What can you do if there is a sudden change in the weather?

  • Limit motor activity;
  • Avoid additional emotional and physical activity;
  • Control your blood pressure and  do not ever forget to take the medications prescribed by your doctor;
  • Do not overeat and do not eat too much salt;
  • Before going to bed, walk in the fresh air for at least 1 hour;
  • Take an anti-anxiety medication;
  • Never forget to take vitamins C and B;
  • In the case of an increase in blood pressure, massage your neck and thoracic spine.



When people discover something is good for them, they seem to think that the more of that “good” thing the better. As Paracelsus has said “All things are poison and nothing (is) without poison; only the dose makes that a thing is no poison.” The same goes for exercise. Regular, moderate exercise is extremely beneficial for a person’s health. However, when we delve into the realm of competitive sports, our thinking makes a 180 degree turn.

Not only do professional athletes go through exhaustive training regimens, they also, quite frequently, resort to doping. The time when it was possible to win without doping is long gone. Now it’s all about who gets caught. For example, in strength training, even if a person has amazing genetics and doesn’t use drugs, he will have no chance of winning when going further than a regional competition.

The risks for developing a cardiovascular disease differ depending on various factors, including a person's job and place of work. Researchers have found the risk of heart diseases may also depend on the industry sector in which a person works.

There are 2 main groups of occupations that are harmful for the heart.

pilot 2If your occupation falls into any of these two groups, you should take increased care of your heart and vessels in order to avoid the negative influence your job has on your heart and to prevent serious health problems. 

The 1st group includes occupations that combine:

  • Low physical activity;
  • Situations in which one needs to quickly evaluate a situation and make crucial decisions;
  • Responsibility for a large number of people;
  • 24-hour shift schedule and night shifts.

The-Heart-of-the-Matter 2

As you live your life, you gradually begin to realize how important it is to keep healthy. Some people realize it too late, when they are affected by a disease. It should be easy to realize early on. All you have to do is look around and see how poor health hinders a person’s life. Notice an overweight man at a bus stop wheezing and trying to stand up to catch the bus. He is not just overweight; the wheezing and shortness of breath with overweight people is usually caused by heart problems – one of the most common and debilitating problems a modern person can face.

The overabundance of food and the lack of movement have done their job and now more than 70% of people in the United States are either overweight or obese, with half of them having some sort of heart problem. However, even people who are not overweight can suffer the same fate. This can either be caused by poor genes which promote the development of atherosclerosis, or by some other heart-damaging disease.


There is a logical answer to this question – if your heart hurts, then it is no longer healthy. But in reality, other conditions may be revealed. People who complain to doctors about pains in the heart may often are given an unclear diagnosis – cardialgia or false angina. This term, unless there is strong indication of angina pectoris, usually applies to all types of pain localized to the left of the sternum or anywhere in the left half of the chest.

 Human psychology is such that it demands an explanation for any disease a person may suspect having. Knowing perfectly well that the heart is located in the left side of the chest and having only vague understanding of what else could hurt in that area, most people would think that it’s the heart that hurts. This situation is facilitated by the fact that the overall level of common medical knowledge is limited to believing the most dangerous diseases are those of the heart.

Sedentary Lifestyle – the main cause of heart disease

People that are inactive, do not participate in any active sports, do not go to the gym, and barely move at all, are at a very large risk of becoming fat. Unless you have a very fast metabolism, which can slow down as you age, you will eventually grow fat, unless you burn off those extra calories. And, as you might know, this is the main risk factor for heart disease, including hypertension, angina pectoris, and heart attack.

yoga for hypertensionUncontrolled hypertension, is undoubtedly, a major threat to public health worldwide based upon the amount of evidence available. Likewise, there is an abundant amount of evidence-based knowledge available on how to prevent this costly disease. Yet there has been a widely acknowledged failure achieving adequate prevention and treatment in our society. There are many contributing factors explaining this failure. One obstacle in the prevention of hypertension is that it is a disease that typically has few, if any, symptoms. An obstacle in the treatment of hypertension is patient adherence.

heart health and alcohol

Is there any truth behind these claims and what will be the result if you actually drink small amounts of alcohol every day.

How does alcohol affect our cardiovascular system?

A great number of studies have concluded that moderate consumption of alcohol (1 drink per day) actually has a number of positive effects on the cardiovascular system. 1

healthy heart foods

What is troubling you could be more about what you shouldn’t eat, since you will receive little or no benefit from eating the foods mentioned on this list if you do not correct your diet first.

Obesity and heart

It cannot be stressed enough how important being slim is in order to have a healthy heart and to live a longer, more fulfilling life. In the past, the main cause of death was disease and starvation. Now the tables have turned and the main killer is the obesity.

The percentage of people that suffer from obesity is growing with each passing year. In this article we would like to tell you about this serious problem and address the following issues:

  • Why are we, as a nation, getting fatter?
  • How does obesity affect the heart?


Green tea: processing and bioactive compounds

Tea or Camellia sinensis is the most popular beverage in the world and is considered healthy due to the presence of antioxidants and other bioactive molecules with known benefits to the human body. Green tea is obtained when the harvested tea leaves are withered and heated either using steam (Japanese method) or by firing in a pan (Chinese method). This process halts oxidation of the leaves and helps in retaining the green color and delicate fresh aroma.

Interaction of bioactive compounds in the human body

Both, black and green tea contain small amounts of xanthine alkaloids as well as caffeine (1 -5%). Green tea also contains high amounts of phenolic substances or tannins (5 - 27%), which contain catechin (flavonol) and gallic acid, but the concentration of these compounds is higher in green teas when compared to black teas.
