Aerobic Exercise

Aerobic exercises refer to those physical exercises that we like to do most. They are not so tough to do. But it is only that we can do them for a long duration. The term aerobic is used to refer to oxygen because the energy is generated out of this exercise with the utilization of oxygen.

For example, running or walking is done for a long duration but we do not generally put a lot of effort to do them. Swimming and bicycling also come into this category. Now one can understand what is an aerobic exercise. The intensity of the exercise is moderate and done for a long duration.

Then what are the benefits of this type of exercise? It reduces the blood pressure and most important for adults and older people. Our muscles used for respiration get strength and improve our respiratory abilities. Reduce troubles associated with lungs. Easy breathing and pumping of the blood by heart becomes efficient. Red blood cells also increase as the oxygen is needed for this exercise.

Anaerobic exercise

Anaerobic exercise unlike aerobic exercise does not involve use of oxygen to generate energy. This type of exercises are used to develop muscles so that the person can do great in short duration and high intensity activities.

Aerobic exercises are generally running, walking, bicycling and swimming. These are done for longer durations of time with less effort compared with an anaerobic exercise. Oxygen is used up to produce energy in aerobic exercises. This has many long term health benefits.

Unlike aerobic exercise anaerobic exercises are not performed for long term benefits but for short intense bursts of energy needed by muscles for performing wonderful feats. Many athletes and bodybuilders resort to this type of exercises.

Strength training

Strength training is for doing physical exercises and has many health benefits. It involves use of heavy weights to oppose gravity or using elastic forces. This has several health benefits apart from increasing the size and strength of muscles.

Strength training is done initially by lifting as much weight as possible by a person. Then the muscles respond to grow larger and stronger. As the person repeats the process the muscles grow larger and he/she need to steadily increase the weights also. This is how the process expands muscles gain size and strength.

Strength training reduces the potential for injuries to the body. It improves cardiac functioning and thus reduces the chances of a heart attack. Bone, muscles and ligament get strength and grow over time. Cholesterol level also increases.

Food Flavor is Causing Lung Disease

The California food flavoring workers were found to have an obstructive lung disease. This was a rare and life-threatening lung disease. This disease was also known as popcorn workers lung. It slowly eliminates lung capacity and necessitates a transplant.

Artificial butter flavoring called diacetyle, which is used in microwave popcorn flavoring plants is linked with this disease. Many flavoring manufacturers have paid hundreds of million dollars for workers affected with this disease. Now the politicians and workers are on their way to ban this chemical. One death was also confirmed because of this.

Tea Antioxidants Found to Reduce the Risk of Skin Cancer

Skin cancer risk was observed to be less in those who take regular tea by researchers. EGCG, a tea oxidant is shown to reduce burning on ultraviolet exposed skin. However it is also found that those who have already had skin burns in the past, did not have the lower risk of skin cancer.

But it doesn’t mean that one can go and expose to sun all the time. Extreme exposures are not covered. The tea antioxidant might be just limiting the skin damage caused by moderate exposure and not extreme exposures.

Another tip for memory boost

A new study conducted on medical students revealed that memory can be boosted up by 10 percent. This is achieved by those students who did move their eyes from side to side in the morning. It is similar to other exercise we do in the morning.

The doctors explain this by saying that the two hemispheres of brain interact with each other when eyes are moved from side to side.

Also revealed in the study is the reduction in false memory by15 percent. False memory means remembering misleading things which are not real but imagined memories.

HIV-Test Mandatory Before Marriage?

Wondering this is for real or fake? Now the government is going to decide to make the HIV-Test mandatory before marriage so as stop spreading HIV further.

It is the Karnataka Government in India was examining the proposal of Health Minister. It is well known by now that many unsuspecting women have married men with HIV positive. This is terrible.

But what remains is that the whole world follows a policy of non-disclosure of blood test results (or HIV results) to anybody including the subject. If the test is made mandatory then it creates another problem in the society. How is the bride or bridegroom going to decide to cancel the engagement if the result is HIV positive? It can lead to chaos in the society.

Work-At-Home is Risky for Health

Often we can see that those who work at home do not use proper ergonomic guidelines and thus land in many injuries. One such deadly illness is the problem of blood clot formation in legs. It generally happens when a person sits for long hours without stretching. Flight travels and non-ergonomic work environment often lead to these problems.

Without ergonomic guidelines one will get a lot of other problems. All are listed under the category – repetitive stress injury. In a previous blog, I talked about the necessity of ergonomics for work-at-home.

Woman’s anger

Now those women who cannot control anger and who are more ill-tempered than others can blame that on their genes. A study reveals that hypertension is related to genes and this makes them more vulnerable to diseases.

How is a woman’s anger is related to the genes? Researchers found that a gene helps produce serotonin, a brain chemical that regulates emotions and moods, which is linked with lower aggression and anger in humans and animals. An alteration in the promoter region of the a specific receptor gene is said to found in the aggressive and angry women.

Chocolates Can Save Us from Cancer, Heart Disease and Strokes

Recent study says that a particular chemical compound called Epicatechin found in cocoa beans is as important to medicine as penicillin or anesthesia. Even when people become prone to attack and they take cocoa they are less likely to die.

It is said that the chemical compound Epicatechin improves health by relaxing blood vessels and improving circulation. Also one suffering from dementia, impotence, and pre-eclampsia, a life-threatening complication of pregnancy, can benefit from these cocoa chocolates.

In a previous blog I had written about the same cocoa benefiting memory.

Cell phone calls do not interfere with medical equipment in Hospitals

Cellular phone calls are discovered not to interfere with medical facilities in hospitals. This dispels the long-held notion that they are unsafe to use in hospitals. But other technological devices like CD players and anti-theft devices fitted in stores can affect the functioning of patient care equipment.

For example implanted heart devices can malfunction in the presence of CD players and anti-theft devices installed in stores. Perhaps the store employees must learn to move away those people having troubles.

I think this could be because of the frequency of operation of the device and also voltage. For cellular phones, they operate at very high frequencies like Gigahertz while CD players operate at lesser frequencies in the range of few Kilohertz. The medical equipment in hospitals and patient care equipment also operate at low frequencies. Indeed they are designed for a specific person and not for communication. So the frequency and the sphere of influence are limited. So is the case with CD players.

Can chocolates benefit brain and improve memory?

Do you eat chocolates? I used to eat. I stopped eating chocolates after coming to know that it is not a health food. It can even affect out teeth. I think most of the people knew these things about chocolates. As I was crawling through the web I found an interesting news. Many students generally eat chocolates and other stuff while working night-outs just before the exam.

A recent study says that the chocolates benefit the brain and memory. They stimulate the flow of blood to the brain and thus benefit the functioning of brain. I had just found it on Google news.

Some say that the effect of chocolates in stimulating or creating alertness is distinct from the stimulating effect of caffeine on the brain. Some other say that the chocolates are nevertheless unhealthy food.

I am confused whether to eat chocolates or not. I am thinking that the artificial stimulation whether it is from chocolate or caffeine must be having some side-effect. Unless needed in emergency or highly profitable business I decided not to take them. Also being a youngster makes me feel like take good care of my future health.

Children Born with Blindness Could be Protected Through Proper Diet of Mother

The children’s eyes are vulnerable for damage because of the vessel growth in the eye. Children who are at risk for vision loss could be protected through proper diet.

The children get their diet from mother. So the diet of mother is essential for controlling the damaging vessel growth in the eyes of the children. A study revealed that the omega-3 fatty acids have beneficial effects on the eyes. Currently this study is done in mice. The Children’s Hospital at Boston has plans to test it on children.

There are three reasons for blindness. One is the abnormal vessel growth in the eyes of premature babies. The others are adult diabetic retinopathy and wet age-related macular degeneration. The retina is affected when a child is affected with retinopathy. Thousands of children are affected with retinopathy every year. The retina, which sends visual signals to the brain, is an essential part for a functioning eye. The disease begins with the loss of blood vessels in the retina. Because of this the retina starts growing new vessels to avoid the deficiency of oxygen to it. These may grow abnormally, and overabundant. They malfunction and lead to blindness.

The only solution that is found for this is the omega-3 fatty acids containing DHA and EPA acids. These are present very less in the children. There is also omega-6 fatty acid which actually increases the vessel growth. Hence a balanced ratio of these two acids needs to be maintained through diet. The research found that many children have lesser omega-3 fatty acids compared to omega-6 acids. Hence fish-oil supplements are required in the diet of the child. As this problem occurs especially in premature infants the diet of mother needs to be enriched with fish-oil supplements.
