I would like to tell about a healthy way of life and its advantages for man.A healthy way of life is very fashionable nowadays. But it is not only popular; it is also useful for our organism!People, who lead a healthy way of life, follow some rules: go in for sports, temper, eat healthy food, keep to a day regimen and walk frequently in the open air.Perhaps, sport occupies the most important place in a healthy way of life. You can do exercises in the morning  and you can practice various sports.The most important thing is to choose for you something real. You should really start something.Tempering also takes an important place in maintaining the vital tonus. It includes dousing with cold water, a contrast shower, rubbing with snow  and other procedures. Tempering supports the vascular tone.We shouldn’t forget about healthy eating either. Proteins, fats and carbohydrates should be balanced. Proteins are the«bricks» that make up the body's cells. Your body needs fats that reserve energy and calories. Carbohydrates are the main supplier of energy for life. Dietary fibers stimulate good digestion, protect the organism from dietary carcinogens and help to prevent many diseases. That’s why it is not recommended to limit you in products, which contain proteins, fats, and carbohydrates. But it is necessary to limit yourself in sweets, salt, spicy and fried foods, and also strong carbonated drinks.It is also important to keep to a day regimen. We should go to bed and get up at approximately the same time.And, of course, it is necessary to spend more time outdoors, whether it is winter or summer.Bad habits and a healthy lifestyle are incompatible.So, if we follow a healthy way of life, we will live a long and beautiful life. Take my advice.
