Over 80% of modern people use their upper chest for breathing at rest. It is easy to observe this phenomenon in public transport, restaurants, waiting rooms and many other places. Medical studies suggest that overwhelming majority of people with asthma, bronchitis, COPD, cystic fibrosis, terminal cancer, severe heart disease, and many other conditions are chest breathers.
At the same time, it is known that advance of many chronic diseases is always accompanied by lowered amount of oxygen in the brain and body cells. Furthermore, severely sick and acutely ill patients often require supplemental oxygen, regardless of the details of their chronic disease (heart disease, epilepsy seizures, respiratory disorders, neurological, hormonal, and so forth). Whatever their health condition, critically low brain and heart oxygen levels are most likely causes of possible deaths.
What are the health effects of thoracic breathing on oxygen transport? Oxygen delivery cascade is very sensitive to any abnormalities that can appear on the way from outer air to body cells. In health, as medical books suggest, we use mainly the diaphragm for breathing at rest: it does up to 80-90% of the work of breathing. Moreover, since the diaphragm stretches the whole lungs in the vertical direction, all alveoli in the lungs get fresh air supply and vital oxygen. Therefore, the diaphragm provides hemoglobin in the arterial blood with up to 98-99% of oxygen saturation.
Chest breathing means taking in air with your ribs and chest muscles. Obviously, chest breathing brings a lot of oxygen to upper portions of the lungs. What about the lower portions of the lungs? Are they important? Dr John West in his medical textbook Respiratory Physiology claims that the upper 7% of the human lung delivers 4 ml of oxygen every minute, while the lower 13% of the lung delivers in 60 ml of oxygen per minute.
Therefore, lower portions of the human lungs are about 6-7 times more effective in oxygen transport. This phenomenon is probably due to the effect of the gravitational force: more blood flows at the bottom of the lungs than at the top of the lungs. Chest breathing drastically reduces oxygenation of the blood.
Furthermore, chest breathing is a normal result of chronic hyperventilation. Consider the medical facts. People with normal breathing breathe very slowly and little: only about 10-12 breaths per minute with 500 ml for one breath. In contrast, chest breathing is larger and deeper: often more than 18 breaths per minute at rest with up to 700-900 ml for tidal volume in moderate heart disease, diabetes, bronchitis and other conditions.
For some poorly understood reasons, when we start to hyperventilate (chronic overbreathing), we breathe more with the chest muscles. Hence, it may look like a total paradox, but during large thoracic breathing (deep and fast), blood oxygen levels are reduced due to inhomogeneous gas exchange. In addition, this large breathing reduces CO2 levels in the arterial blood causing another health disaster that is called hypocapnia. (Low blood CO2 also contributes to reduced brain oxygenation due to vasoconstrictive effects.)
Therefore, it is normal that chest breathing can greatly contribute to hypoxemia (low levels of oxygen in the arterial blood) and the development of emphysema, asthma, bronchitis, cystic fibrosis, heart disease, diabetes, cancer tumor growth, and other pathologies.
Clinical experience of Soviet and Russian medical doctors practicing the Buteyko breathing technique suggests that people make a natural transition to diaphragmatic breathing when they slow down their automatic (unconscious) breathing back to the medical norm and their body oxygen levels is about 40 seconds.

The Dangers of Herbal Supplements
Many plants have curative properties so it's no wonder that herbal medicines have been used for hundreds of years. Before today, plant parts would be gathered and ground in a poultice to be administered to a person with an ailment. Now you can get herbal extracts in the form of syrups and capsules. There doesn't seem to be any harm in modernizing ancient natural medicine-but can we become sure that is entirely safe? The answer is that no, herbal supplements cannot be guaranteed to be safe for everybody. There are herbal products that will prove to be too strong for some people, while there are some that can trigger severe allergies. These are just some of the risks that we face when we take herbal supplements, because they aren't as tightly regulated as normal medicine and moreover, herbal supplements do not have to pass Food and Drug Administration standards in order to be released to the market. People don't need prescriptions for them, so it's very easy to get your hand on practically any herbal supplement that you want.
Herbal supplements fall under a category called dietary supplements. As such, the manufacturers are allowed to claim benefits from taking their products as long as it is backed by research and they place a tag on their products that the claims are not verified by the FDA. They are safe in the sense that the FDA is mandated to monitor the products' safety while on the market, but bar any serious complaints, they will continue to be sold in the market. In order to be sure about the safety of taking a product, talk to your doctor first before taking any herbal remedy. You may need to disclose lifestyle habits as well as existing medications that you are taking since some chemical interaction with herbal formulations may have dangerous health consequences.
All herbals must contain product information that includes a list of all the ingredients used for it. The best thing to do is to go through this list and take note especially of the active ingredients. If there is something that you do not know, ask your pharmacist or do some research on the ingredient before making your purchase. On the label you will also find the benefit claims for the particular herbal supplement. While the manufacturers must back their claims with research, the FDA does not require them to submit evidence of the research. So it is best to be a wise consumer and do your own investigative work on any herbal supplement that you intend on taking, as some unscrupulous suppliers may be exaggerating their claims or covering up risks for better marketing. It is always better to err on the side of caution. There are certain instances when people are advised against taking herbal remedies altogether or when they must absolutely seek the advice of their doctor before taking them. These are for people who are under prescription medication (and even some OTC medicines), women who are pregnant or currently breast feeding, people who are about to have surgery (some supplements may reduce the effectiveness of anesthesia) and for younger (than 18) or older (than 65) people.
If you do decide to take herbal supplements you should do so with care. First of all, you should follow the manufacturer's instructions and resist the urge to overdose. You should also check the expiration date to make sure that you are not taking expired medication. Also, it is better not to take herbal supplements that are made outside of the US, for safety reasons. Moreover, best to stick with proven and tested products with no history of serious complaints and avoid products that are still in their experimental phase.

Reduced Blood Flow: An Overview
Unless there is an existing medical disorder in a younger person, blood circulation is normally more of a concern for older adults. Many factors can be at work in reduced movement, but it does look to happen with advancing age. However, there really is little reason for that to necessarily be a predicament. Behavior and means are obtainable to increase the movement when needed. Prevailing medicine and other areas have discovered many lifestyle behaviors that can impact circulation.
The advantages of consuming enough water are well acknowledged to most of us. Our bodies are more or less 75% water which is marvelous and that has significant implications. For efficient operation of our bodies, we must be certain to supply the appropriate things. Some specialists used to suggest a daily water ration of eight ounces, which is looked at as obsolete today. One thing we have read very frequently, though, is that you should in no way allow yourself to feel thirsty. Moderate dehydration has already begun as soon as we experience the sensation of thirst. Also, do not depend on non-water beverages as your primary source of water. Consume water throughout the day. Make sure that it is free from impurities.
Numerous U.S. residents maintain active lifestyles, but there's been a major general trend toward sedentary living. But it is much more widespread for older adults to embark on settling into a inactive life. This is never a good idea for general health. But it's mostly poor for the blood circulation. This shouldn't come as a shock. After all, your muscular tissues are just accomplishing more effort when you're body is in motion. The act of expanding as well as contracting your muscle groups, and increasing heart rate, will robotically get the blood moving more. Take a hike. It will get your blood moving better each time.
There are several bad behaviors that eventually hurt your overall level of blood flow. One culprit, which has numerous harmful effects on health, is a bad diet. High-quality food, proper sources of energy, result in a very well-tuned metabolism. You could obtain energy from fats and sugars, but you will not be getting all the natural vitamins and minerals desired by your body. To better your blood circulation, be sure to incorporate all those factors -- get enough water, enough nutrients, and enough exercise.
If there's oodles of tension in your life, believe it or not, this could also lower your blood flow. If you stay in a continuous state of tension, the stress hormones produced in the body can actually damage the body itself. Among the effects of stress is constraint of your cardiovascular system. The stress hormones your body releases into the blood in fact create this outcome. This method will moreover cause your blood pressure to climb and your blood to clot more easily.

Treating Leg And Ankle Pain
If you are an athlete or are involved in heavy physical activities all the time, one of the things you would usually suffer from is leg or ankle pain. The pain may be a result of conditions such as a strained calf muscle, tendonitis or shin splints. Whatever the reason, you can be sure that the injury can affect your life greatly especially when the condition is ignored. With the help of basic treatment, you will be able to ease or even get rid of the pain.
Total rest is perhaps the best way to treat any kind of bodily pain regardless of its cause. When you rest, you give the injured part of your body (in this case the leg or the ankles) the time to heal and recover. Along with rest, hot or cold compressions are also recommended. While the coldness of the ice prevents further swelling by reducing blood flow to the injured area, a warm compress right after can help ease the veins and muscles, promoting healing and fast recovery.
Taking anti-inflammatory drugs also work effectively to reduce pain and inflammation on the affected area. Common anti-inflammatory medications may include Naproxen, ibuprofen and the well-known aspirin. Using these kinds of medication along with proper rest and ice treatment is a suggested technique to treat leg and ankle injuries. Using topical cream to help alleviate the pain may also be an effective idea.
A more natural way of treating leg and ankle injuries is through stretching. Stretching exercises can help relax tensed joints and muscles. This is usually used when there is a desire to engage in physical activity again after the doctor has given approval. Simple exercises such as light walking or cycling are good examples of light exercises you can try when recovering from a leg or ankle injury.
The period set for recovery from leg or ankle injury usually depends on the degree of the severity of the pain. It can also depend on how you are improving in your treatment or therapy. That means, the more dedicated you are in improving your condition, the faster you are going to recover from the pain or injury.
You never know whether a pain in the leg or the ankle is simply pure pain due to a minor injury or a more serious one that requires further treatment. In case the pain you are experiencing extends to more than four days, you would need to consult your doctor and find out the underlying cause for such condition.
