Choosing the Right Keyboard and Mouse Wrist Pad

Computer work has become the backbone of most of our daily lives. But with its rise in the workplace, there has been a concurrent increase in injuries associated with repetitive computer work, such as carpal tunnel syndrome and repetitive strain injury. Incorrect usage of a keyboard or a mouse can be the culprit, since unnatural keyboard positions exert stress on the muscles, tendons and ligaments in the hands and wrists. An unsupported wrist can be the cause of wrist fatigue, and if your wrist is resting in the incorrect position, extensive typing, can pose a threat.
Ergonomic equipment can help to minimize the risks of injury during extended computer work. If you are a frequent computer user, it might be worth investing in an ergonomic mouse pad or keyboard.
When looking for an ergonomic mouse pad, there are some key features to take into consideration. Look for a mouse pad that allows you to maintain your natural hand position. It needs to imitate the position the wrist has when at rest, by providing an angled surface. Also, make sure the mouse pad has a non-slip grip to ensure it remains in place under normal movement. Purchasing an ergonomic mouse pad and choosing one made from soft material or filled with a soft gel can help to remove the pressure from the tendons and nerves. Hard materials cause compression and pressure on the tendons and nerves in the wrist, and can lead to pain and discomfort. Most importantly, check that the pad is comfortable, offering a good position for your wrist at rest and good freedom of movement while working.
When it comes to keyboards, a wrist rest is a good investment, since it's designed to give your wrists a break after typing for long periods of time. If you're typing incorrectly, it helps to alleviate the pain associated with repetitive strain injury or carpal tunnel syndrome. A good wrist rest helps to keep your wrists off the edge of the hard desk and can also help to prevent incorrect posture during typing. Before buying a wrist rest, make sure you know the height and width of your keyboard. There are many styles available on the market, and it's important to find the wrist rest comfortable for you. It needs to be the same height and width of your keyboard and it's key to find a wrist rest that conforms to the shape of your wrist. When placing the wrist rest against the edge of the keyboard, there shouldn't be a gap between the two. Adjust the position so that the wrist rest is set at the edge of the desk.

Do Thin People Need Exercise?

Many people believe that exercise is something only fat people should do, and a lot of people exercise with the sole goal of losing weight. So why should thin people exercise if they are already at the ideal dress size and optimal weight?
Even though exercise helps a great deal with weight loss, it also improves our health in many other ways such as reducing the risk of heart disease, lowering cholesterol levels and reducing high blood pressure. Even though these conditions are associated with obesity health risks, thin and sedentary people shouldn't assume they are risk-free. Lean exercisers have good levels of LDL cholesterol, the heart clogging variety, as youíd expect. However their thin but inactive counterparts were found to have the same levels of LDL seen in obese people! In fact, an overweight exerciser is actually more likely to be comparable to a thin exerciser rather than an inactive thin person in terms of cholesterol levels. Having high cholesterol and a risk of heart disease is more about how much exercise you get, rather than what your body mass index is. A study [1] found that lean exercisers were fitter and had a reduced chance of developing cardiovascular diseases compared to those who don't exercise. Exercise is essential for a healthy heart ñ no matter your weight.
Exercise is also helps protect against viruses and disease. In the short term, regular cardiovascular activity can help to boost the immune system, and in turn makes you less susceptible to viruses such as the common cold, influenza and helps to protect against any kind of infection. In the long term, regular exercise makes the body overall healthier, by lowering the risk of serious diseases such as strokes, heart disease, high blood pressure and cholesterol, diabetes and even cancer.
Being thin and being healthy and strong are not a given. Just as there are overweight people who are in good health (the type who exercise), there are many thin people who are far from healthy. Those who work out can run and walk faster and longer distances, and on the whole, have greater endurance.
Exercise is also a great energy boost. It can help to burn away fatigue and raise energy levels. People who work out more often find they sleep better and are more refreshed during the day. If you're suffering from mental disorders such as depression or anxiety, exercising allows you to disconnect and alleviate stress and relax the mind. Endorphins are released after exercise, which are helpful in battling depression.
Finally, physical activity does keep the pounds off. Most thin people who are sedentary have a fast metabolism, and in some cases this is for life, but for many of us as we age, our metabolisms will slow down and we will inevitably gain weight. So it is in everyone's best interest to get in the habit of working out and keep those pounds off!

Can Chiropractic Improve Golf Performance?

PGA golfers Tiger Woods and Padraig Harrington have used chiropractic services for years in order to improve and maintain their golfing performance. Their successes suggest a benefit of chiropractic care, but itís hard to know if itís because of the care or because they are world-class athletes. Can chiropractic care help the average golfer improve their performance as well?
The very nature of the game of golf suggests a good match for players with chiropractic care. Golfing can involve considerable strain on the spine. Golfers need to move from a standing position quickly to club head speeds, requiring good posture, balance, and the ability to rotate the spine properly. Poor posture can create exaggerated or flattened spinal curves that can seriously affect swing performance. In fact, Tom Ward, PGA Golf Instructor, says, ìOver 50% of all golfers will experience some sort of pain due to poor posture and the problems that arise from loss of proper curves in the spine.î[1]
By working with your spinal range of motion, chiropractic care can help correct golf injuries, maintain performance, and improve the posture needed to perform a good golf swing. When the chiropractor aligns all the vertebrae, the spine can move better. An individualized treatment plan including chiropractic adjustments, specific rehabilitation exercises and muscle techniques may make a significant difference in your overall performance and enjoyment of the sport.
Recent research confirms that chiropractic care can indeed lead to improved golf performance. A recent study published in the Journal of Chiropractic Medicine demonstrated that the combination of chiropractic care and stretching are associated with greater improvements in golfers swing when compared to stretching alone.[2]
Two groups of golfers participated in the study. One group received a program of stretching only, and the second received both stretching and spinal manipulation. The stretching program was the same for both groups, and both groups had similar average ages, handicaps, and initial swings. All 43 participants initially performed three full swing maneuvers, and the average distances were recorded. Over a 4-week period, all participants hit 3 balls before and after treatment.
After 4 weeks, the stretching only group showed no improvement in swing performance. However the stretching and manipulation group did improve their swing performance and there was greater driving distance right after treatment each week. So it appears that yes, chiropractic care can help not only top golfers such as Woods and Harrington, but it can help you improve your golf game too.

C-Reactive Protein 101

With frequent news coverage of late, C-Reactive protein is a term that has been bandied about in the media ñ but what is it exactly? Produced in the liver, C-Reactive protein, or CRP, is a protein that is released into the bloodstream as a response to inflammation in the body. High levels of CRP are a cause for alarm, since its presence can be linked to inflammation possibly arising from infection, lupus, tuberculosis, heart attack risk, burns and even cancer [1].
CRP is believed to play a significant role in the bodyís early defense mechanism against infections [2], where its physiological role is to bind with a compound present on the surface of dead and dying cells, and even some bacteria, known as phosphocholine. It then activates the complement system, a part of the immune system called the ìinnate immune system,î via the C1Q complex [3].
The usefulness of the C-reactive protein is its ability to determine the progress of a disease, and it can also be used to assess whether a treatment for diseases associated with inflammation are working or not. In order to measure the levels of CRP in the blood, first a blood sample from the patient must be collected and analyzed. The levels of CRP in healthy individuals are negligible and will not show up in the test. For sufferers of diseases associated with inflammation, the test will show various levels of CRP in the blood. The measurement of CRP in the bloodstream not only can also help to determine whether someone is at risk of heart disease, but also assesses the severity of the risk [2].
Studies have found that patients who have raised basal levels of C-Reactive proteins are at an increased risk from diabetes, hypertension and cardiovascular diseases [4][5]. There is also a strong correlation between the lipid responses to low fat and high-polyunsaturated fat diets and CRP levels [6].
Some organs in the body are at an increased risk from cancer when they become chronically inflamed, and such inflammation may be highlighted by the presence of CRP in the body. In one study [7] samples were collected from sufferers of colon cancer and a control group, the average levels of CRP in those with colon cancer measured 2.69mg/l, whereas those in the control group had a mean value of 1.97mg/l. With significant difference between the two groups, this supports previous studies that connect the intake of anti-inflammatory medication with the lowering of colon cancer risks [8].
While the measurement of CRP cannot pinpoint the exact location of the inflammation in the body, it can be used to monitor and detect the presence of diseases associated with inflammation, and can monitor whether medication is effective on inflammatory diseases being treated.

Chiropractic Care for Triathlon Performance and Recovery

A triathlon is an athletic event incorporating back-to-back running, cycling and swimming. Triathlons exert great strain on the body, which may challenge athletes on both physical and mental levels. The extreme training a triathlete must endure can put the body under great cumulative stress, and itís not uncommon for the athletes to suffer from a broad range of injuries and overuse stresses.
There are numerous worldwide triathlon events, such as Ironman, Half-Ironman, Olympic and Spring. The majority of these events advocate the use of chiropractic care to aid not only in treating injuries, but also to improve performance. Chiropractic care offers the possibility of enhanced finishing times and a greater likelihood of triathletes finishing events.
Chiropractic treatment is a practice that focuses on the neuromuscular skeletal system and its use optimizes biomechanics. For these reasons, chiropractic care is ideal for athletes looking to treat or prevent injuries.
One type of chiropractic treatment used by many triathletes is the ìActive Release Technique,î which is a form of soft tissue treatment based on an advanced movement massage system. It is very effective in locating and treating the cause of soft tissue conditions. Active Release Techniques are used in most of the large name triathlons. Many triathletes suffer from injuries attributed to repetitive strain and stress, since excessive training can result in muscle restrictions due to adhesion formation. Before treatment takes place, a biomechanical analysis of the athlete is conducted to determine the exact location of restrictions in the body along the kinetic chain. Active Release Techniques focus on specific tissues that have become restricted physically, and are then manipulated back into their original texture, tension and position. Once the soft tissues are repositioned, specific exercises are then carried out in order to aid the recovery of damaged tissues. Unlike most treatments, treating the injured triathlete with chiropractic care does not require extended rest periods before improvements are seen. It is very common that injured athletes who receive the Active Release Technique show signs of improvement in just a few sessions. For those who are looking to invest only in preventive treatment, improvement in performance is also achieved in the span of a few sessions.
A possible reason that chiropractic care prior to an event can result in performance enhancement may be that spinal adjustments improve the bodyís maximal oxygen consumption ability. Since prevention is easier than treatment of an injury, many professional athletes invest in preventive and performance enhancing chiropractic treatment.

Is High-Fructose Corn Syrup That Bad?

High fructose corn syrup is a popular ingredient in sodas, fruit flavored drinks and most processed foods. It has become a staple alternative to cane sugar in many foods and beverages, but is it safe? There has been much controversy and debate over the health effects from long-term usage of high-fructose corn syrup. So far, research has yielded mixed results about its adverse consequences.
High consumption of added sugar in any form can lead to numerous health problems, including weight gain, dental cavities, poor nutrition and increased risks of heart attacks. While the health concerns of excess sugar consumption may seem obvious, what about the specific case of high-fructose corn syrup? Should we go out of our way to exclude it from our diet, even in moderate consumption?
High-fructose corn syrup and cane sugar are not biochemically identical ñ cane sugar is a naturally occurring ingredient, whereas high-fructose corn syrup is an industrial product, and is processed differently by the body than naturally occurring sugar [1]. Sometimes high-fructose corn syrup is produced from genetically modified corn [2].
A study at Princeton University [3] found that rats from two test groups, one that consumed high-fructose corn syrup and another standard table sugar, yielded different results in the ratsí obesity -- even with the same caloric intake. The group of rats that consumed high-fructose corn syrup experienced abnormal weight gain ñ particularly in the abdominal region ñ and also elevated triglyceride levels. Along with high quantities of HDL, otherwise known as bad cholesterol, high triglyceride levels can cause arterial blockage and may increase the risk of heart disease, hypertension and even strokes.
Consumption of high-fructose corn syrup increases the risk of developing Type 2 diabetes [4]. An increased risk of diabetes was observed from the metabolic profile in the study of rats that were given sugar-sweetened beverages, exhibiting impaired glucose and insulin homeostasis.
Long-term liver damage has been cited as a side effect to consuming high-fructose corn syrup [5]. This is particularly risky to individuals who live a sedentary lifestyle. Excess consumption can also result in a fatty liver [6].
One indirect health concern pertaining to high-fructose corn syrup is the contamination of mercury [7]. Mercury cell chlor-alkali products are used in the manufacturing of high-fructose corn syrup, which may leave a trace of the toxic heavy metal in its products, which can be up to 0.5micrograms/g of corn syrup. When you consider the average consumption of corn syrup as being around 50g per day, this could lead to a dangerous build up of the heavy metal in the bodyís system.

Chiropractic Care for Allergies

When most of us sneeze, we put it down to a cold or even allergies, and our first thoughts are to pop an antihistamine pill ñ not to call a chiropractor! But did you know that a chiropractor could help you overcome your allergy problems? Most people associate chiropractors with back and neck issues, and while itís true that chiropractors can help with such health conditions, they can also help the body achieve optimum health by ensuring the spine is correctly aligned.
A study from the University of California [1] found that signals from the nervous system may influence the function of the immune system. While our immune system is there to fight against viruses, disease and infection, and helps to keep the body performing at its peak, it also works to dispel foreign contaminants that enter the body. When we sneeze because of an allergy, itís because our body detects the presence of a foreign object in the system, such as dust, mites, pollen, etc. and it produces chemicals to neutralize and expel the allergens. These chemicals are known as histamines. In the case of allergies, the immune system overreacts to the presence of the allergens in the body.
A chiropractor may help by removing the nerve interference from compressions in the spine, and as a result the immune system is able to function optimally once more.
Most traditional treatments for allergies, such as antihistamines, only deal with managing the symptoms and donít eliminate the cause. The safety of anti-allergy medication is under debate, the long-term use of antihistamines or combined with other medication may cause cancer. A study conducted in lab rats with brand name anti-allergy medication found that cancerous tumors in the rats grew much father with the intake of antihistamines [2].
A chiropractor treats the patient by releasing the stresses on the patientís nervous system, which as a result causes the immune system to work more effectively and as a consequence allergies are thereby reduced. Patients with misaligned spinal vertebra may have pinched nerves, which apply pressure and stress the system. Once the trapped nerve is released, the nervous system in general is free from stress and the body can then work more effectively to neutralize the allergy-causing chemicals found in the body.
Spinal health is as beneficial to the body as is good nutrition. A chiropractor can help the body to achieve optimal health and can help to improve the quality of life.
