Once a French doctor I knew complained to me about Russian tourists, whose health he had to monitor on a cruise ship. Almost every day one of them experienced a hypertensive crisis! And pensioners from Europe, who also sailed on this ship, rested peacefully. The ship's doctor could not understand why Russians constantly have headaches and high blood pressure, while European tourists do not complain about such complaints? In fact, this is easy to explain - in European countries, citizens over 40 years of age undergo an annual medical examination, at their own discretion do not stop taking prescribed medications and do not prescribe new ones for themselves, follow a diet and do special gymnastics and therapeutic walking. That is, they do everything to prevent the development of cardiovascular diseases and their exacerbation. The same, unfortunately, cannot be said about our compatriots. Listening to the story of the ship's doctor about hypertensive crises among Russian tourists, I felt deeply offended for my fellow countrymen. Well, insurance medicine doesn’t work so effectively for us yet! This means that everyone must take care of themselves. How exactly? I talked about this in the book that I dedicated to cardiovascular health. The encyclopedia is a reissue of the books “120 to 80. A book about how to defeat hypertension, not reduce blood pressure” and “60 beats per minute. A book about how to help your heart regain strength and a healthy rhythm.” Attention! The information contained in the book cannot serve as a substitute for medical advice. You should consult with a specialist before taking any recommended actions.
