Your body when you Swim

Harvard medical school published a study which looked at over 40,000 men, aged 20-90 who were either runners, walkers, swimmers, and physically in active people. With an average length of 13 years of observation and in that time

  • 2% of swimmers passed away
  • 8% of runners passed away
  • 9% of walkers passed away
  • 11% of physically inactive people passed away

This study showed that swimmers are much healthier later on in life than the rest of the population and for women swimming just 30 mins a day can decrease coronary heart disease by 30 to 40 percent.

It also helps to increase HDL aka good Colestrol. Some studies have also shown that aerobic excercise can keep the cells in the lining of your arteries more flexible and healthier. Hence there is no question that swimming is an awesome form of fitness.

Body during swimming

What do you actually feel when you go into the water? Here are some main elements of the human body that gets impacted during swimming.

1. Blood

According to the America Heart Association, swimming is considered as Aerobic activity. Aerobic excercise enlarges the heart and it increases the blood flow through the entire boby. Because swimming is an excercise, the blood has to pump all the molecules into the body.

2. Heart

Since so much of blood has to be pumped into the body, that ties into how it impacts your heart because we know that after 2 mins your body goes into aerobic respiratory because your heart has to pump all the oxygenated blood through the body. So as you swim, your heart is circulating the blood which help your body to perform and achieve the required goals.

3. Skin

You must have seen that the skin color changes of swimmers. For example, some swimmers face turns red when the swim, that happens because your blood vessels are dilating and the brings the heat to the surface into the skin then some people turn red, as a result your skin is showing the effort that you’re putting in the water.

4.Muscles

There’s a reason why swimmers are considered to have best body and physiques in the world compared to any athlete, because swimming engages every single muscles in the water when it comes to your core stability, your upper body, your biceps, your hamstrings, your calves, everything is engaged when you swim.

When you’re swimming, you are micro tearing your muscles while swinging it. And the muscles requires 24-48 hrs to recover those muscles. That’s when sometimes you might feel sore.

5. Lungs

Swimming can actually help increase your lungs volume because in swimming different than other sports, you can’t actually breath whenever you want. It’s not like running when you have full access to oxygen.

In swimming you’re engaging your muscles and you’re not allowed to breathe necessarily at the time when your body might want it. So because you have to get used to this, you actually increase your Vo to max (maximum amount of oxygen body is able to use). So basically you are making your lungs more efficient at functioning.

6. Brain

The Brain loves swimming, because of all the extra blood flow moving through these endorphins that makes you more awake, alert and focus.

But this could happen in any type of sport but swimming is something really special because you’re sort of in your own world where the medium is 800 times more dense than air, which makes you feel free and relaxed.

Hence, from physical health to mental health, swimming is an incredible benefit human body and after reading this you must be thinking of trying swimming.

Organ Donation: Myths and facts

Every years, many thousands receives the gift of life, a life saving transplant of Heart, Kidney, Liver, Lungs, Pancreas and Interesting. And thousands more people receive Corneas and other tissues that restore sight and health. Organ transplantation is one of the medicals advances of our time.

How does it work?

It all starts when someone’s organ begins to fail and that person will need a transplant to survive. The steps are as folllow:-

  1. A through evaluation is conducted at a transplant centre and the person is a good candidate for transplant, he or she will be put into the National Transplant Waiting List.
  2. Once a person is on the waiting list, the wait for organ begins.
  3. A national system matches people on the waiting list with donors. That factors matching donors to recipient includes
    • Blood type
    • Body size
    • How sick the patient is
    • Distance from donor
    • Tissue type
    • Time on list

What isn’t taken into account, organs are never matched based on

  • Race
  • Gender
  • Income
  • Celebrity
  • Social status

There is no telling how long the wait will take. Infact, some people don’t receive an organ in time, because the Waiting List is really long and there aren’t enough donors available. That’s why an average of 20 people on the Waiting List died each day. Imagine how many could we save if we all were donors.

Becoming a donors

Most of organs transplant comes a deceived donors. For example, a person comes to the hospital with a life threatening brain injury, such as from an accident, stroke, our lack of oxygen. The doctors work hard to save them patients life but sometimes nothing can be done. There’s a complete, irreversible loss of brain function. The patient is clinically and legally dead.

Thats when being a donor can turn a time of loss into a time of hope. Because machines have blood containing and oxygen flowing into the organs, they can be passed along. One person can give life to as many as eight people through organ donation, and enhance the lives of fifty people or more with eye and tissue donation. But now minutes matter, matches must be found and transplants must happen quickly.

Organ Procurement organization

The hospital contracts an Organ Procurement Organization (OPO), it manages the recovery process. The OPO checks the state of organ donor registry, if the person is already registered as a donor they inform the family, if not they’ll ask the family to authorise donation.

A medical examination is taken place. They check the medical and social history and the person is eligible to be an organ donor, the computer begins to search on the National Waiting List for well matched patients The best matched patients are contracted by the transplant team. This is the call that every person on the Waiting List was waiting for.

The Transplant

A surgical team recovers the organs, then Corneas and other tissues. The organs are sent to the transplant hospital where patients and transplant teams are waiting and the life saving transplant takes place. It will take health living and medication to keep the organ working well in its new home.

You too could make the decision today, sign up on your state registry as an organ, eye and tissues donor, any age is the right age, Young or old, any day is the right day to sign up as a donor. You can register through your drivers license or you can register online. Remember to tell your family so that they can support your wishes. More than 1r5 million people have already registered, and we all need to save kore lives. So let’s share the gift of life.

Blood Harvest.

So we all know about horse shoe crabs those infamous hideous looking gentle and harmless organism sometimes termed as the living fossil because of their presence on our planet since millions and millions of years. So blood harvest happens on the blood of a horse shoe crab which has a striking baby blue colored blood due to presence of copper rich haemocyanin agents(like we have iron rich haemoglobin).The marvelous thing about horseshoe crab blood, though, isn’t the color. It’s a chemical found only in the amoebocytes of its blood cells that can detect mere traces of bacterial presence and trap them in inescapable clots. To take advantage of this biological idiosyncrasy, pharmaceutical companies burst the cells that contain the chemical, called coagulogen. Then, they can use the coagulogen to detect contamination in any solution that might come into contact with blood. If there are dangerous bacterial endotoxins in the liquid—even at a concentration of one part per trillion—the horseshoe crab blood extract will go to work, turning the solution into what scientist Fred Bang, who co-discovered the substance, called a “gel.”

“This gel immobilized the bacteria but did not kill them,” Bang wrote in the 1956 paper announcing the substance. “The gel or clot was stable and tough and remained so for several weeks at room temperature.”If there is no bacterial contamination, then the coagulation does not occur, and the solution can be considered free of bacteria. It’s a simple, nearly instantaneous test that goes by the name of the LAL, or Limulus amebocyte lysate, test (after the species name of the crab, Limulus polyphemus).The LAL testreplaced the rather horrifying prospect of possibly contaminated substances being tested on “large colonies of rabbits.” Pharma companies didn’t like the rabbit process, either, because it was slow and expensive.

The only problem is that the companies need a large supply of the blood of live crabs. Horseshoe crabs live on the seafloor, near the shore. When they want to mate, they swim into very shallow water, and horseshoe crab collectors wade along, snatching the crabs out of their habitat. The biomedical collectors are not the first to make use of the crabs’ bodies. As far back as colonial times, “cancerine fertilizer” was used to enrich fields. In the 20th century, though, this became an organized industry around the Delaware Bay. The crabs were steamed and then ground into meal for the fields. Others were fed to hogs. Millions of crabs were harvested.

After the biomedical horseshoe crab collectors get them back to a lab, they pierce the tissue around the animals’ hearts and drain up to 30 percent of the animals’ blood. The LAL is extracted from the blood, and can go for $15,000 per quart. Only five companies bleed the crabs: Associates of Cape Cod, Lonza, Wako Chemicals, Charles River Endosafe, and Limuli Labs .The horseshoe crabs are returned to the ocean a great distance from where they were initially picked up to avoid rebleeding animals. The whole process takes between 24 and 72 hours.The industry says that not that many of the animals die. Between 10 and 30 percent of the bled animals, according to varying estimates, actually die. We can imagine that it’s like us giving blood. The crabs get some apple juice and animal crackers and are fine soon thereafter.But some people have noticed problems. In the regions where horseshoe crabs are harvested in large numbers for biomedical purposes

Horseshoe crabs are an ancient animal, more than half a billion years old. They have their own ways of doing things, a fact we’ve been exploiting for decades.Our own species evolved a thousand times more recently, coming into our current anatomical form a couple hundred thousand years ago. Let’s hope we don’t wipe horseshoe crabs out after we finish cloning their ancient chemical wisdom.
