All of you know all too well Raynaud's syndrome. You open the refrigerator door - and your hands are suddenly chilly. Or you notice the changes in the fingers, when they hit the keyboard. The blood vessels that go to the toes, are drastically reduced. (Sometimes also subjected to the action and toes.) Initially developed spasm. Blood flow to the affected area slows down, and from the lack of blood, rich in oxygen, it becomes pale and may even acquire a bluish tint. Sometimes, lack of blood, you feel a sense of numbness. When blood returns, the fingers turn red again. In advanced stages of the disease Raynaud's poor blood supply can weaken the fingers and prevent sensitivity. Cold is not the only culprit. It is strange but widespread disease can be the result of damage to the blood vessels of the vibration power equipment, such as power saws and pneumatic drills, and from increased sensitivity (hypersensitivity) to medications that affect blood vessels or connective tissue disorders. Other causes include nerve disorder. How can I protect myself from Raynaud's syndrome? Here's advice of American specialists.
Tempered to overcome the cold. Train your hands, so they warmed themselves in the cold with the help of adaptation according to the procedure developed by scientists from the US Army in Alaska. Choose a room with a normal, comfortable temperature and lower hands in a container of warm water for 3-5 minutes. Then go to a very cold room and then soak your hands in warm water for 10 minutes. Cold environment will cause the peripheral blood vessels to shrink, which is normal, but instead of the feeling of warm water, they will expand. Re-training of the blood vessels to expand, despite the cold, may allow you to resist the pressor reflex, even without hot water. The army experiments, this procedure was repeated daily for 3-6 times for 150 persons formed the experimental group. After 54 treatments the results were impressive: the hands in the cold were 2.5 ° C warmer than in the past.
Waving his hands to make it warm. And you can actually get your hands warm with the help of simple exercises, which came up with Dr. Donald McIntyre, a dermatologist from the state of Vermont. Imagine that you throw a tennis ball. Wave a hand down the back of the back, and then forward in front of him, and do it at a rate of 80 strokes per minute (it's not as fast as it sounds, try it). The effect of the windmill, which Dr. McIntyre modeled, as well as exercises for warming skiers, forcing the blood rushes to the fingers under the law of gravitational and centrifugal forces. This warming is good for the frozen fingers, regardless of the reasons for cooling.
Eat foods rich in iron. From lack of iron can change the metabolism of the thyroid gland, which regulates the body heat - as believed by scientists from the Research Center for Human Nutrition in North Dakota. They investigated the effect of iron contained in the diet, for 6 healthy women when they were in the cooling chamber. When the women took only a third of the recommended amount of iron for 80 days, they lost 29% more heat from the body than when were on iron rich diet for 114 days. Foods rich in iron include poultry, fish, lean meat, lentils, green leaf vegetables. Also it works well orange juice, because it increases the body's ability to absorb iron.
Eat hot, plentiful food. The very act of eating increases the core body temperature. This is called thermogenesis. So eat something before you go to throw fuel into the body. And eat something hot, to cheer up. Saucer hot oatmeal to a morning walk, soup or hot lunch will help keep warm hands and feet even in severe weather.
Drink more. Dehydration can impair cooling and frostbite by reducing blood volume. Avoid hypothermia by drinking plenty of fluids - hot soup, herbal tea or broth.
Beware of coffee. Coffee and other caffeine-containing products reduce blood vessels. If you have Raynaud's syndrome, probably, it is unlikely you will want to interfere with circulation.
Avoid drinking alcohol. Resist the temptation to have a drink and a hot toddy. Alcohol temporarily warm your hands and feet, but its adverse effects outweigh its benefits as a sogrevatelya hands and feet. Alcohol increases blood flow in the skin, giving an immediate feeling of heat, but this heat is soon lost in the air, reducing the internal body temperature. In other words, actually gets colder from alcohol. The danger is that by drinking excessive number and leaving a long time in the cold, you can get severe consequences, such as frostbite.
Dress warmly, to maintain internalbody temperature. To keep warm, you need to dress warmly. Yes, it's all clear, but many people pull the gloves and socks, without taking the same precautions to maintain core body temperature, which is much more important.
Choose a fabric that absorbs sweat. Cause cold hands and feet, even to a greater extent than the low temperature is sweating. Particularly sensitive hands and feet, but is on the palms, feet and armpits has the largest number in the body of the sweat glands. That is why from the thick wool socks and boots with inner lining of pure wool, which you bought to keep your feet warm, the feet may sweat and freeze.
It is better to wear socks mixed with cotton yarn than pure cotton socks. You want to wear socks that would have removed the sweat off his feet. Socks made of pure cotton can absorb moisture and cool your feet.
Make sure that the clothes free. None of you are wearing must not reap. Tight clothes: stockings, suspenders, belts, jeans or tight shoes can disrupt blood circulation, in addition, there is no insulating air layers.
Dress in layers. If you go out in the cold, the best way to warm up - a dress in layers. This helps trap heat and allows you as the temperature changes take off their clothes as onion peel. The inner layer should consist of one or several synthetic filaments, such as polypropylene, which absorbs the perspiration from the skin. Also suitable fabric of a mixture of synthetic fibers, silk or wool. The next layer is to isolate you, delaying body heat. The best option - a woolen shirt. Dress in watertight. Choose not impede breathing waterproof jacket or windbreaker, appropriate shoes or boots to keep their feet warm and dry.
Wear a hat. Another great part of your clothes, you can wear to warm his hands and feet - this hat. Head - place the greatest heat loss from the body. The blood vessels in the head are monitored cardiac activity, and not reduced, like vessels in the arms and legs. "If you want to keep your hands and feet warm, - says Dr. John Abruzzo, director of the rheumatology department, and professor of medicine at Thomas Jefferson University, - wear a hat: it is just as important as wearing gloves and socks."
