The Finnish sauna is considered "the drug of the poor" and now researchers have demonstrated that the steam really very beneficial for health.
Scientists have discovered that the dry heat of the sauna is not only made to sweat but can extend life, reduce the risk of heart disease in middle-aged men up to 63%.
The Finnish sauna has started thousands of years ago. The first was digging holes in the ground and fill them with hot stones, then sprinkled water over them to create steam. It is said that each room has a steam sauna with a particular individual characteristics.
The study was conducted on 2,315 men from 42 to 60 years old from Eastern Finland and followed them for more than 21 years.
They have recorded 190 cases of sudden cardiac death, 281 cases of death due to coronary artery disease, 407 deaths from heart disease and 929 deaths from any cause.
However the regular saunas seem to be protected from heart problems.
Research shows that the risk of sudden cardiac death in 22% lower than those gassed 2-3 and 63% in those who gassed 4-7 times per week.
Similar results were also found for coronary artery disease, with the steam went 2-3 down 23% risk of death was reduced by 48% and 4-7.
The rate of death from heart disease decreased by 27% when they went 2-3 and steam saunas 50% when 4-7 times per week.
the steam under 11 minutes each time, the possibility of sudden cardiac death by the steam from 11-19 minutes less than 7% in the risk of the steam more than 19 minutes down 52%.
Previous studies have shown that steam can reduce blood pressure and stress hormones your help diabetes disease of the lung, and even against the common cold and certification anorexia.
Some athletes use steam to enhance their endurance by increasing the volume of oxygen, the number of erythrocytes and plasma volume. And the cold water plunge pool after the sauna can enhance the body's antioxidant and boost the immune system.

Health Benefits of Grape Seed
Phil Lampert, renowned food expert in the US, said: "The composition of grape seed useful is proanthocyanidin".
The study was conducted from 1950 showed that grape seeds have a wide range of health benefits, most notably as an antioxidant free radical reducing agent cum powerful, as well as the ability to reduce high blood pressure and cholesterol. As an antioxidant, proanthocyanidin proven 20 times more effective than vitamin C and 50 times more than vitamin E.
Proanthocyanidin also benefits the vascular system because they strengthen the walls of blood vessels. This helps reduce the risk of broken capillaries which can make us vulnerable to excessive bruising. Improving the integrity of blood vessels and helps to effectively pump blood vessels and relieve reflux, varicose veins and aneurysm
Also, according to experts, due to its anti-inflammatory, proanthocyanidin may be used to treat asthma, arthritis, injuries and swelling, and can reduce the severity of allergies.
Lampert Expert advice: eat grapes with seeds, or buy grape juice or grape seed oil 100% pure.

Effects of smoking to the cardiovascular system
While cardiovascular disease affecting young people is a fact, the doctors said that the cause is constantly smoking habits. And if you think that women are not threatened by the disease, think again because the majority of patients are young women. Work stress coupled with a sedentary lifestyle that women are losing their biological protection with heart disease.
The cardiologist said that nearly 12% of women of working age in the city of Pune (India) will be affected by heart disease at a young age in 2020, this figure one decade ago was 2.5%
Dr. Ajay Kale's Lokmanya Hospital Chinchwad (India) said that of the 500 patients (10% female) are being treated for heart disease in 2013, 50% of patients who smoke. Some young women start smoking to lose weight, because they believe that nicotine affects the appetite that we do not feel hungry, eat less and thus reduce weight.
By Rekha Aditya Birla Hospital Dubey, then 30% of the patients were taken to hospital for heart disease are smoking. Manoj Kadam - a regular smokers - are examples of young people working in an IT company. With busy schedules, sleeping and eating less often, Manoj was myocardial infarction at a young age unexpected
The study shows that pressure, curiosity is the most common reason for a person starts smoking. Most smokers said that they smoke regularly to relieve stress. However, a lot of them end up in a special care unit of the hospital for cardiovascular disease. The doctor also said that five years ago, the case is not known. But the number of young people admitted to hospital for cardiovascular disease and increasing smoking is the main risk factor. In the past few years, the hospitalization related to heart under age 40 increased by about 30-40% of which are heavy smokers.

Top 10 Healthy Foods for Preventing Heart Disease
The food you eat can affect your risk for heart disease, one of the top killers of American women and men, according to Womenshealth.gov. Heart disease can occur when plaque builds up in the arteries, causing them to narrow and restrict blood flow to your heart. Reading nutrition labels can help you select products low in saturated and trans fats, sodium, sugar, additives and cholesterol. Each food group contains many nutrient-rich choices, so you do not have to sacrifice flavor and variety to benefit from the best heart healthy foods.
Fish
The American Heart Association recommends eating at least two 3.5-ounce servings of fatty fish per week. Good choices include salmon, mackerel, trout, sardines, herring and albacore tuna. They are high in omega-3 fatty acids, which help lower the risk of heart disease and reduce blood pressure. These oily fish are a good source of selenium, an antioxidant-rich mineral that helps protect the body from heart disease, according to the Better Homes and Gardens website.
Lean Meats
Foods high in saturated and trans fats raise levels of LDL cholesterol, also known as “bad” cholesterol, which increases your risk for heart disease. Choose lean meats and cook without additional fats. Baking, grilling and broiling are healthy ways to prepare meat.
Poultry
Poultry, especially skinless chicken or turkey breast, is a better choice than fatty meats, which contribute to coronary artery disease. Broil, bake or grill white meat chicken and turkey, and whether you are eating at a restaurant or preparing meals at home, try to avoid foods that are fried or sautéed.
Grains
Unrefined grain products are heart-healthy.The fiber in unrefined whole grains can help lower “bad” LDL cholesterol. Whole-grain flours provide more vitamins than processed, milled white flour found in regular pasta and bread, so choose 100 percent whole-grain bread and whole-wheat pasta, natural brown rice and whole-grain breakfast cereals. Oatmeal is a filling, heart-healthy breakfast choice.
Nuts and Seeds
Almonds, walnuts and other nuts are rich in omega-3 fatty acids and fiber. A review in the July 16, 2013 issue of "BMC Medicine" explains that plant-derived foods and oils are rich in mono- and poly-unsaturated fats and may improve cholesterol levels and lower your risk of heart disease. Flaxseeds contain fiber and omega-3 and omega-6 fatty acids and can be added hot or cold cereals to provide a heart-healthy breakfast ingredient.
Vegetables
Increasing the amount of vegetables you consume adds fiber that can limit the absorption of cholesterol and may reduce your risk of heart disease. Dark leafy green vegetables, such as spinach, romaine lettuce and broccoli, provide iron, potassium, vitamin K and other vitamins and minerals. Carrots, sweet potatoes and squash contain vitamin A in the form of beta-carotene, an antioxidant, plus vitamin C, which offers protective heart benefits, according to the February 2010 issue of “STAR WELLNESS.” Vegetables also provide you with fiber that can limit the absorption of cholesterol.
Fruit
Fresh fruits such as apples, bananas, peaches, pears and plums are heart-healthy sources of fiber. Berries are full of vitamins and antioxidants that may lower your risk for heart disease. The vitamin C in fruits, such as oranges and tomatoes, may have protective heart benefits. Prunes are a good source of fiber and iron, and, if eaten regularly, may reduce “bad” LDL blood cholesterol.
Legumes
Legumes, such as pinto, black and kidney beans, chickpeas and lentils, are low-fat, high fiber protein sources . They are cholesterol-free, vitamin-rich and contain minerals, such as calcium. Tofu and other soy products -- edamame, veggie burgers, soy milk and tempeh -- are lean protein sources, and eating them for snacks or meals may lower LDL cholesterol and reduce your risk of cardiovascular disease.
Oils
Using unsaturated oils in food preparation may help reduce triglycerides, high fat levels in your blood that may increase your chances of developing coronary artery disease. Olive oil is full of monounsaturated fats and may help lower LDL blood cholesterol and decrease your risk of heart disease. Olive oil, flaxseed oil, canola and other unsaturated oils contain both omega-3 and omega-6 fatty acids.
Dairy
If you eat whole-fat dairy foods, such as yogurt, cheeses, creamy sauces and butter, or if you still drink whole or 2 percent milk, try to substitute fat-free, low-fat or reduced-fat dairy products. Whenever possible, choose nonfat or 1-percent milk, cottage cheese or yogurt and part-skim, low-fat or fat-free cheeses.

4 effects of yoga on heart
Yoga is a great way to maintain the balance of the body, but the new study suggests that regular yoga practice can bring you much more about other health benefits. Here are 4 ways that yoga can help your cardiovascular health.
Yoga helps relieve stress
When you encounter a stressful situation, your brain secretes adrenaline to help you either fight or flee the threat. This makes your heart beat faster and blood pressure rises. Although this reaction can help you protect yourself when faced with a threat, to live in a state of constant stress can wreak havoc on your cardiovascular system. According to the Association of Cardiovascular and Stroke, the most susceptible to stress are at risk for heart disease than those who calmer.
Yoga can help by calming response to your stress. Experts said Yago can prevent and treat several diseases, including heart disease, by improving the imbalances related to stress in the nervous system.
Yoga helps reduce inflammation
Inflammation is the body's way of reacting to trauma and adverse situations, including stress. But inflammation is the nature of most diseases, including heart disease.
Learning to relax with yoga may help reduce inflammation-related stress. A recent study showed that when women do yoga regularly exposed to a stress factor, they are less inflamed than the beginner set.
Yoga can reduce blood pressure
According to the Association of Cardiovascular and Stroke, long-term high blood pressure can weaken the heart and blood vessels affected, leading to the formation of plaque and stenosis or occlusion of blood. It is the leading cause of heart attack and stroke.
But unhealthy eating and lack of exercise are the main risk factors, but stress has also been linked to high blood pressure. Yoga is a way of antihypertensive effect because it has the ability to soothe the stress response of the body.
Advanced Yoga physical activity
According to the Association of Cardiovascular and Stroke, the passive risk of heart disease than double those who exercise regularly. Yoga improves strength and toughness, which is very important for cardiovascular health.
Research shows that people who practice yoga are also capable of maintaining an exercise routine better. A study in 2012 had registered for the passively participate in a yoga class twice / week for 10 weeks. The researchers found that participation in yoga class this dramatically increases the ability of the participants in the study will continue to engage in physical activity later.

The Internet is making your child has high blood pressure?
Since the Internet emerged, our lives have changed significantly. While older generations encountered many difficulties in the use of smartphones, tablets, social media and applications over the younger generation probably will not know what to do if one day the Internet to disappear.
This affects how your health?
According to the latest research, spending more than two hours a day sitting in front of a screen - any public display - increases the risk of hypertension by 30% ... in both adults and children.
Spending less than an hour for physical activity also increases the risk of increased blood pressure by 50%.
These results come from a two-year study on 5221 children from eight European countries (Spain, Germany, Hungary, Italy, Cyprus, Estonia, Sweden and Belgium) in age from 2 to 10 at the start of the study. After two years of research, more than 10% of children diagnosed with high blood pressure.
The child in a state of passive than 2 hours / day have the ability to have high blood pressure higher than 30%, while those who do not spend at least 1 hour / day for physical activity are at risk for high blood pressure more than 50%. It is important for high blood pressure at an early age also significantly affect the blood pressure to rise higher in adulthood.
According to the researchers, the solution is simple: time limit screen time at 2 hours / day and ensure that your children spend at least 1 hour / day for physical activity.

Women under 60 with diabetes have a higher risk of cardiovascular
DCC results from the research from Johns Hopkins University of Medicine published in the journal Diabetes Care showed that the risk of coronary heart disease will be much higher for women who are young and middle-aged type 2 diabetes (common in overweight people)
Generally women under 60 years of age at risk for coronary disease than men blinds at the same age. But for women with diabetes in this age group, the risk of heart disease was 4 times.
Dr. Rita Rastogi Kalyani, who led the study, said the findings, we need to work harder to prevent cardiovascular disease for women with diabetes are under the age of 60. The study also showed that that women with diabetes at any age regardless of risk of coronary heart disease is high. On the other hand, less diabetes affect cardiovascular risk in men.
The researchers analyzed data from 10,000 participants in three large studies. None of the participants had a history of cardiovascular disease. All 3 studies were obtained sex differences were similar to keep the incidence of diabetes and cardiovascular risk.
The study adds evidence that gender differences exist when considering the risk of cardiovascular disease caused by diabetes. Interestingly, in both men and women, these findings are not related to differences in obesity and cardiovascular risk factors such as high blood pressure, cholesterol and smoking.

How to Get Omega-3 Fatty Acids Without Eating Fish
Omega-3 fatty acids are an essential part of balanced nutrition, helping to keep the heart functioning properly, lowering cholesterol, regulating blood pressure and even reducing inflammation due to injury and arthritis. While fish is the best source of omega-3, it is not the only source--good news for vegetarians and those who don't love fish.
Things You''ll need
Flaxseed (oil, seeds and/or capsules)
Nuts and seeds
Soy
Green leafy vegetables
Fish oil capsules
Instructions
- 1Choose the second leading source of omega-3 fatty acids, flaxseed. While flaxseed oil is better than seeds, both are great sources. Oil and seeds can be sprinkled on salads, added to your favorite recipes, blended in smoothies or juice or taken in supplement form.
- 2Eat more nuts and seeds, natural sources of omega-3. While nuts and seeds are generally high in fat and calories and should not be relied upon as your only source of essential fatty acids, the occasional crunchy snack or salad addition will help to boost your intake of omega-3 without eating fish. While most nuts and seeds contain omega-3, walnuts are at the top of the list.
- 3Add more soy to your diet, another great source of omega-3. Tofu can be prepared just as you would chicken or mixed into casseroles. Soy can be purchased in a variety of forms, such as milk, cheese, meat alternatives and even ice cream.
- 4Include more green leafy vegetables in your diet, including kale, broccoli, cabbage and even seaweed. All green leafy vegetables contain at least small amounts of omega-3 fatty acids, so including them in your daily diet will most definitely help you reach your daily goal.
- 5Get fish oil without eating fish by taking omega-3 from fish in supplement form. However, it is recommended that you do not take more than 2.5g each day, as fish often contains heavy metals which can build up in the body. If you require more than 2.5g daily, consider flaxseed oil supplements or other dietary methods.

Using too much caffeine can cause a heart attack?
Caffeine helps increase your alertness and ability to concentrate, but excessive use can lead to some unwanted side effects. In addition to coffee and tea, caffeine usually in black cocoa, milk chocolate and additives in soft drinks, energy drinks and coffee ice cream. Slightly addictive nature of caffeine can lead to headaches when people were accustomed to abrupt dose reduction or discontinuation.
Using caffeine to stimulate neural activity of body, brain and blood vessels leading to contraction and increases the heart rate. The impact is mild or severe depending on the amount of caffeine you consume and your sensitivity to this matter. Due to faster heartbeat and blood flow is increased to push the narrowed blood vessels, so your blood pressure temporarily increased when drinking beverages containing caffeine.
The average caffeine content of the doctor recommended that the 200-300 / day. Absorption on 600mg caffeine / day would probably not enough to cause a heart attack, but combined with rapid heartbeat and feeling the pounding in his chest will make you at risk for the disease. The anxiety and restlessness increased by using too much caffeine also makes the symptoms worse.
The abuse of caffeine combined with eating habits unhealthy, high blood pressure and smoking can lead to cardiovascular disease. When the heart does not work effectively due to abnormal heart rhythms or body fatigue, blood may accumulate in the heart leads to the formation of blood clots, stroke, or myocardial infarction. Caffeine content in the average user may not be harmful, but if you are suffering from heart disease or abnormal heart condition, please note the use offline.

Your blood type may put you at risk for heart disease
People whose blood type is A, B or AB have an increased risk of heart disease and shorter life spans than people who have type O blood, according to a new study.
But that doesn't mean people with blood types other than O should be overly concerned, because heart disease risk and life span are influenced by multiple factors, including exercise and overall health, experts said.
In the study, researchers followed about 50,000 middle-age and elderly people in northeastern Iran for an average of seven years. They found that people with non-O blood types were 9 percent more likely to die during the study for any health-related reason, and 15 percent more likely to die from cardiovascular disease, compared with people with blood type O. [Beyond Vegetables and Exercise: 5 Surprising Ways to Be Heart Healthy]
"It was very interesting to me to find out that people with certain blood groups — non-O blood groups — have a higher risk of dying of certain diseases," said the study's lead investigator, Dr. Arash Etemadi, an epidemiologist at the U.S. National Institutes of Health.
The researchers also examined whether people's blood type may be linked with their risk of gastric cancer, which has a relatively high incidence rate among the people living in northeastern Iran. They found that people with non-O blood types had a 55 percent increased risk of gastric cancer compared with people with type O blood, according to the study, published online today (Jan. 14) in the journal BMC Medicine.
The association between blood type and people's disease risk and life span held even when the researchers accounted for other factors, including age, sex, smoking, socioeconomic status and ethnicity.
Previous studies have shown that people with non-O blood types may be at higher risk of certain cancers and cardiovascular disease, but it was less clear whether blood type is linked with life span, Etemadi told Live Science.
About 11,000 people in the study provided information about their blood's biochemistry, including their cholesterol levels, glucose levels and blood pressure. But only certain metrics stood out — for example, the people with type A blood tended to have higher levels of total cholesterol and LDL cholesterol, also known as the "bad" cholesterol.
It's possible that higher cholesterol levels could partly explain the increased mortality risk. People with non-O blood types also have an increased tendency to form blood clots, and this higher coagulation might lead to more heart problems, Etemadi said.
Moreover, the gene that is responsible for blood type is on the same chromosome as some of the genes responsible for controlling blood cholesterol, Etemadi said.
But it's unlikely that the cholesterol link is solely responsible for the difference in people's life span, he said. "We think that it's a mixture of both causes that contribute to this increased mortality," Etemadi said.
Although people with non-O blood types may have these increased risks, they should "absolutely not" be concerned that their blood type is the determining factor in their health, said Dr. Massimo Franchini, director of hematology and transfusion medicine at the Carlo Poma Hospital in Italy, who was not involved with the study.
"Belonging to a non-O blood type represents only a risk factor (among many others), and actually, there are many and many millions of people worldwide with non-O blood type that do not have, and will never develop, any of these diseases," said Franchini, who wrote a commentary on the study that was also published in the journal. "Thus, in my opinion, a healthy lifestyle still remains the main factor able to influence the health status of an individual."
