Brief Guide To Airguns
Ever since paintballing has caught the attention of people, the popularity of air guns has increased phenomenally. Now you have many types of air guns on the market. That is the reason why you should be sure which air gun would be most appropriate for you when you go to buy one.
Airguns work by using compressed air or other type of gas to propel pellets, bb’s, and similar kinds of ammunition. Most airguns are low-powered for safety reasons, but there are more high-powered airguns that have been used for military and hunting events. High-powered airguns are used in the Olympic sharpshooting events. These high-powered airguns have the advantage of being extremely accurate, but are not usually the best type of airguns for normal airgun activities.
The most commonly used air gun is the multi-stroke, more commonly known as pump up. In order to propel the pellet from the barrel of the air gun the pump-up guns need several “pumps”. These guns are lightweight and relatively smaller. They have moderate power and don’t retreat back much. However, the drawback of these guns is that they require a lot of time and energy to hit the target and they don’t have a great accuracy. A multi-stroke gun might not be the best option for those looking for a gun with a high accuracy.
On the other hand, single-stroke air guns deliver a high degree of accuracy. They only need a single pump to get the proper amount of air. These air guns are also more consistent than the pump-up variety. Plus, there is no problem of recoil with single-stroke air guns. But, single-stroke air guns don’t provide a lot of power. That is why the hunters don’t prefer to use them. On the other hand, there are many people who feel the high accuracy of single-stroke air guns makes up for the lack of power.
There is also an option of purchsing pre-charged air guns, which have high accuracy and high power. The pre-charged air guns need a minimal effort to get the air as they are derived from the scuba tank. The scuba tanks are equipped with a special hose having a pressure gauge in order to supply the compressed air. The pre-charged air guns are more suited for hunting purposes as some of them yield multiple shots. Thus, a combination of all these factors make the pre-charged air gun the perfect choice for a host of air gun activities. However, even these guns suffer a little from the problem of recoiling.

Blood Pressure Facts

High blood pressure is a major risk factor for coronary heart disease, stroke, heart failure, peripheral vascular disease and renal failure. High blood pressure is more likely to develop among people who are overweight or physically inactive, or have high dietary salt intakes. Hypertension is one of the most frequently managed problems in general practice worldwide.

The heart pumps blood around the body through the blood vessels. Blood pressure is the amount of force exerted on the artery walls by the pumping blood. High blood pressure (hypertension) means the blood is pumping with more force than normal through arteries. This added stress upon the arteries could possibly accelerate the distribution of arteries with fatty plaques (atherosclerosis).

Other risk factors for atherosclerosis include cigarette smoking and high blood cholesterol. Atherosclerosis contributes too many heart illnesses, such as heart attack and stroke. Hypertension is a common disorder of the circulatory system, affecting around one in seven people.

Hypertension usually produces no symptoms. This means most people don’t even realize they have it. Experts recommend that everyone should have their blood pressure checked regularly.

When the heart contracts the blood inside the left ventricle, is forced into the aorta and arteries. The blood then enters small vessels with muscular walls, called arterioles. The tone within the muscular walls of the arterioles determines how relaxed or constricted they are. If narrowed, they resist flow.

Reduced flow of blood is detected in the brain, the kidneys and elsewhere. Nerve reflexes are stimulated and hormones are then produced. The heart is induced to beat more forcefully so that the blood pressure is maintained at a higher level, to overcome the restricted flow through the arterioles. The achievement of good flow (now at high pressure) eases possible problems for function of the brain and kidneys. These adjustments happen normally. There are some people that the adjustments become fixed and high blood pressure persists. These people have developed hypertension.

Often, steroids or anabolic steroids are used to regulate the bodily functions or to treat a handful of grave medical conditions. They are also used as performance enhancers, but it should be remembered that there are a number of negative effects of steroids on human body. Steroid users often experience the negative effects of steroids in one form or the other.

There are many negative effects of steroids; some of the negative effects of steroids are that they damage kidneys and liver, which can cause detrimental effects on body. Some male abusers form breasts because of the use of steroids. Due to the increase in testosterone amount inside the body, steroids can cause serious acne problems, which are skin related negative effects of steroids. The negative effects of steroids are also seen in teenagers abusing steroids.

According to a survey, steroids are maltreated by people of all ages. Lots of high school jocks are turning to other alternatives to help their aptitude. Several athletes are addressing some form of performance enhancing drugs. The reports showed that 5% of male high school jocks have used steroids and 2% women use them.

The opinion poll and survey made on what children between the ages of 9 to 13 that covered both children that have and haven’t used steroids, revealed that 47 percent of drug users alleged steroids make muscular tissue stronger and bigger. 43 percent of them that haven’t used steroids said they also believed the drugs made muscles bigger. Only a few have reported the negative effects of steroids.

The negative effects of steroids can cause severe health troubles. Some severer or lasting negative effects of steroids include early hair loss, headache, dizziness, mood swings (anger, depression and aggression), hallucinations, intense feelings of distrust or terror, sleeping troubles, vomiting and nausea, trembling, high level of blood pressure, pain in joints, yellow fever, liver ulcer, urinary problems, shortening of the final adult height, increased risk of developing heart disease, stroke etc.

There a very long list of negative effects of steroids. The women that use steroids run the risk of male pattern baldness. Several negative effects of steroids are even worse. Some people fall into comas after injecting the drugs, some may even die from the injections. The negative effects of steroids can also raise the risk of developing cardiovascular disease and often results in hyperinsulinism and diminished glucose tolerance, changes in lipoprotein fraction, increased triglyceride levels, increased concentration of several clotting factors, hypertension and changes in myocardium.

Cool Down with Hot Summer First-Aid

Cool Down with Hot Summer First-Aid

When the temperature tops 90 and the soles of your shoes sizzle on the sidewalk, cold therapy is a necessity for summer first-aid. Whether it is ice from your freezer, a bag of frozen vegetables or a convenient commercial cold pack, ice therapy has many more uses than treating bumps and bruises.
Here are five summer first-aid tips for cold therapy:
Chill heat-related illnesses.
During the hot summer months, heat exhaustion and heat stroke can be a problem. Symptoms of exhaustion can include dizziness, weakness, a feeling of nausea, excessive sweating and a shallow, quick pulse. With more serious heat stroke, the skin is hot and dry, and mental confusion can occur along with a loss of consciousness. Cold packs can be used to keep the body cool in excessive temperatures, helping to prevent heat exhaustion. Many athletes cool down after a summer event with an icy cold pack on the back of their necks. If symptoms are present, ice packs along with hydration can be used to lower the body temperature to a safe level. Always seek medical attention in the case of heat stroke as this condition can be sudden and deadly.
Ice bug bites.
Let’s face it, insect bites are a nuisance, causing swelling, itching and sometimes pain. Icing a bite immediately will keep the bug poison from spreading to other parts of the body, reduce swelling and inflammation, and numb the area, lessening the need to itch. Use ice therapy on mosquito, bee, spider, fire ant and centipede bites. If an allergic reaction happens or it is a serious bite, such as from the poisonous Brown Recluse Spider, immediately seek medical help.
Keep pets cool.
Even pets can suffer in the summer heat. Keeping them cool can be tricky. An ice pack wrapped in a towel or beneath a thin blanket might do the trick if they decide to snooze on top of it. Ice cubes are a cool treat that some animals enjoy. There are also commercial products made specifically for horses to ice their legs down after a ride. Special caution should be taken to never use a product containing toxins or one that might easily break, endangering a pet if they decide it would be more fun to play with the ice pack than lay on it.
Cool a Burn.
Getting too much sun or being careless around an outside grill can result in summer burns. For minor first degree burns caused by brief contact with a hot object, water or steam, and sunburn, cool the skin by first holding it under running water, then apply a cold pack to numb the pain. If blistering occurs (second or third degree burns) seek medical help.
Cold treatment for night sweats.
Hot summer evenings can mean intense night sweats for menopausal women. A great natural approach to cooling off when awakened by a wave of heat is to tuck a cold pack into the pillowcase so that it lies at the crook of the neck. Within a few minutes, the heat wave will subside, allowing for a restful night’s sleep.
Make sure you have at least one or two cold packs in your freezer for summer first-aid. Chill out and be prepared!

Common Causes Of Stress Incontinence

Incontinence can be caused by several medical problems which includes diabetes or weak pelvic muscles. For women, drying and thinning of the skin in the vaginal area or the urethra causes incontinence especially after menopause. For men, the enlarging of the prostate gland or some prostate surgeries may be the main cause of incontinence. Although incontinence can affect both genders it mostly affects women.

If the pelvic muscles are weakened, a person will be prone to incontinence. This has been the cause of incontinence for many people. There are also some medicines that may cause or trigger incontinence. Consult with your doctor before taking any over-the-counter medicines. Certain medications and antibiotics can cause unwanted side effects such as incontinence.

The build-up of stool in the bowel may also affect a person thus causing incontinence. If a person is unable to move around freely, he may experience incontinence. A simple urinary tract infection may lead to incontinence. Also those people who have high calcium levels and problems such as diabetes are candidates for incontinence.

It is mostly adults who experience incontinence. This occurs when the bladder contractions have overcome the muscles that are forming a ring around the urethra in order to keep it closed. Defects in the nerves of the brain might lead to incontinence developing. These nerves control the bladder activity and if they are not functioning properly there is a knock on effect to other areas in the body. This situation can be caused by a stroke, Parkinson’s disease, or from other conditions that damage the brain.

If the bladder is irritated, it might cause spasms which are not normal. This happens frequently with bladder stones, bladder cancer, and tract infections. This can also be caused by the blockages and tumors found in the colon which pushes it up through the bladder.

If the normal reflexes are lost, the motion of emptying the bladder could be impaired. This can be experienced by those who are experiencing problems with the nerves that lead through the bladder. Also from the damages due to the tumors and spinal cord that presses on the nerves. The loss of the normal voiding reflex can be affected.

The most frequent situation in older adults is unrestrained contractions of the bladder that build up without other serious fundamental illness or cause.

It is important to understand the causes of incontinence so that you can identify them and try to avoid them. Incontinence may be quite difficult to cure so the proper actions should be practiced. Since women are more prone to incontinence, they should be especially watchful for the first signs of incontinence.
