White Tea Facts and health benefits

Many people who want to lose weight and improve their overall health in general have been turning to tea to help them be healthier and prevent many different types of diseases. The health benefits of tea have been proven time and time again, and people have used it for centuries to help them live longer and stay healthy.

There are many different types of tea, from white tea to black tea to green tea. One of the rarest types of tea is white tea, which is found only in China and is actually harvested from the same plants that green and black tea come from as well.

White tea is harvested from the leaves before the buds have completely blossomed; this makes it so the tea is as close to its natural state as possible and goes through less processing than other types of tea. Where black and green tea have both been cured and oxidized, white tea has not.

White tea provides the body and the mind with a number of benefits, many of which are more powerful than green or black teas. Some of the facts about white tea, especially in relation to green and black teas, are:

• Higher anti viral properties. White tea provides more antiviral properties than both green tea and black tea, as a result of its minimal processing.

• More amino acids. Because it is harvested from buds and leaves that are much younger than when black and green tea are harvested, it also has more amino acids.

• More antibacterial abilities. White tea also contains a stronger concentration of antibacterial qualities than do green or black tea. High levels of catechin and gallic acid are also beneficial to the body.

• Higher antioxidant capabilities. Most teas contain antioxidants that are good at cleansing the body of toxins that accumulate throughout the years as a result of pollutants in the air, undigested particles of food, and waste build up. The high levels of antioxidants found in white tea are better at flushing out these toxins, leaving you healthier and more energized.

• Greater cancer fighting abilities. Certain types of teas have been shown to help fight harmful cancer cells and build up cancer-fighting cells within the body. White tea contains the most properties of the various types of tea to help ward off certain types of cancer.

• Greater effect on stress levels. The higher levels of amino acids found in white tea have a better effect on stress levels than black and green teas as well. These acids contain more properties that enhance the mood and lower the stress levels.

Because it is rare, white tea is frequently more expensive than black, green, and other types of tea. However, the health benefits you will receive from drinking white tea are worth it!

One way to get enough white tea is to try White Tea with Acai, which combines the power of white tea with the super fruit Acai berry to give you even more powerful health benefits.

Number of adolescents with HIV jumps by one-third: UN

Geneva:  The number of adolescents infected by the HIV virus has jumped by one third over the past decade, the United Nation’s health agency said on Monday, blaming gaps in care programs.

“More than 2 million adolescents between the ages of 10 and 19 years are living with HIV,” marking a 33 per cent rise since 2001, the World Health Organization said.

“Many do not receive the care and support that they need to stay in good health and prevent transmission. In addition, millions more adolescents are at risk of infection,” it warned.

In the world’s most AIDS-affected region, sub-Saharan Africa, the majority of adolescents with the virus are girls who have had unprotected sex, sometimes under duress.

In addition, many of those born with the virus or infected at birth in sub-Saharan Africa are becoming adolescents.

In Asia, meanwhile, young drug-users were the worst affected.

The WHO said that the failure to provide proper adolescent-focused programs had also resulted in a 50-per cent increase in reported AIDS-related deaths in the age group from 2005 to 2012.

In 2005, 70,000 adolescents died of AIDS. Seven years later, the figure was 104,000.

That contrasted starkly with the 30-per cent decline in the general population, the WHO underlined.

The year 2005 marked the high point of global AIDS deaths, which hit 2.3 million. Last year, the toll was 1.6 million.

“Adolescent girls, young men who have sex with men, those who inject drugs or are subject to sexual coercion and abuse are at highest risk,” said Craig McClure, head of HIV programs at UN children’s agency UNICEF.

“They face many barriers, including harsh laws, inequalities, stigma and discrimination which prevent them from accessing services that could test, prevent, and treat HIV,” McClure added.

“About one-seventh of all new HIV infections occur during adolescence. Unless the barriers are removed, the dream of an AIDS-free generation will never be realised,” he insisted.

The data was issued as the WHO released its first adolescent-specific care guidelines ahead of World AIDS Day on December 1.

“Adolescents face difficult and often confusing emotional and social pressures as they grow from children into adults,” said Gottfried Hirnschall, head of the WHO’s HIV/AIDS Department.

“Adolescents need health services and support, tailored to their needs. They are less likely than adults to be tested for HIV and often need more support than adults to help them maintain care and to stick to treatment,” he added.

Among the measures needed, the WHO said, is an end to the requirement for parental permission to have an HIV test.

In sub-Saharan Africa, it is estimated that in the 15-24 age bracket, only 10 percent of young men and 15 percent of young women know their HIV status.

In other regions, although data are scarce, access to HIV testing and counseling by vulnerable adolescents is consistently reported as being very low, the WHO said.

Malaria, jaundice claim 20 lives in Arunachal in a week

Diseases like malaria and jaundice have claimed 20 lives since last week in Longding district of Arunachal Pradesh, an official report said today.

“This is not the first time when such an epidemic has broken out in Wancho area. In the past, too many such epidemics have been reported.

The reason may be due to the unhygienic way of living and lack of proper health-care facilities,” the report said.

“Though medicines have been rushed they are hardly adequate,” it said. When contacted, Parliamentary Secretary for Information and Public Relation Department, Thangwang Wangham, said that the situation is alarming as every day new cases are being reported.

Wangham, who is the local MLA, said though health workers were in the field there was no tangible respite. The MLA, who is camping at Longding to monitor the situation, has appealed the state government to send relief and more medicines.

Honey bees can be trained to detect cancer

Dezeen_Susana_Soares_Bees_Design_2

Portuguese designer Susana Soares has developed a device for detecting cancer and other serious diseases using trained bees

The bees are placed in a glass chamber into which the patient exhales; the bees fly into a smaller secondary chamber if they detect cancer.

“Trained bees only rush into the smaller chamber if they can detect the odour on the patient’s breath that they have been trained to target,” explained Soares, who presented her Bee’s project at Dutch Design Week in Eindhoven last month.

Scientists have found that honey bees – Apis mellifera – have an extraordinary sense of smell that is more acute than that of a sniffer dog and can detect airborne molecules in the parts-per-trillion range.

Bees can be trained to detect specific chemical odours, including the biomarkers associated with diseases such as tuberculosis, lung, skin and pancreatic cancer.

Bees have also been trained to detect explosives and a company called Insectinl is training “sniffer bees” to work in counter-terrorist operations.

“The bees can be trained within 10 minutes,” explains Soares. “Training simply consists of exposing the bees to a specific odour and then feeding them with a solution of water and sugar, therefore they associate that odour with a food reward.”

Once trained, the bees will remember the odour for their entire lives, provided they are always rewarded with sugar. Bees live for six weeks on average.

“There’s plenty of interest in the project especially from charities and further applications as a cost effective early detection of illness, specifically in developing countries,” Soares said.

Bee’s explores how we might co-habit with natural biological systems and use their potential to increase our perceptive abilities.Dezeen_Susana_Soares_Bees_Design_3

The objects facilitate bees’ odour detection abilities in human breath. Bees can be trained within 10 minutes using Pavlov’s reflex to target a wide range of natural and man-made chemicals and odours, including the biomarkers associated with certain diseases.

The aim of the project is to develop upon current technological research by using design to translate the outcome into systems and objects that people can understand and use, engendering significant adjustments in their lives and mind set.

How it works

The glass objects have two enclosures: a smaller chamber that serves as the diagnosis space and a bigger chamber where previously trained bees are kept for the short period of time necessary for them to detect general health. People exhale into the smaller chamber and the bees rush into it if they detect on the breath the odour that they where trained to target.

What can bees detect?

Scientific research demonstrated that bees can diagnose accurately at an early stage a vast variety of diseases, such as: tuberculosis, lung and skin cancer, and diabetes.

Precise object

The outer curved tube helps bees avoid from flying accidentally into the interior diagnosis chamber, making for a more precise result. The tubes connected to the small chamber create condensation, so that exhalation is visible.

Detecting chemicals in the axilla

Apocrine glands are known to contain pheromones that retain information about a person’s health that bee’s antennae can identify.

The bee clinic

These diagnostic tools would be part of system that uses bees as a biosensor.

The systems implies:
– A bee centre: a structure that facilitates the technologic potential of bees. Within the centre is a bee farm, a training centre, a research lab and a health care centre.

– Training centre: courses can be taken on bee training where bees are collected and trained by bee trainers. These are specialists that learn bee training techniques to be used in a large scope of applications, including diagnosing diseases.

– BEE clinic: bees are used at the clinic for screening tests. These insects are very accurate in early medical diagnosis through detection on a person’s breath. Bees are a sustainable and valuable resource. After performing the  diagnose in the clinic they are released, returning to their beehive.

Bee training

Bees can be easily trained using Pavlov’s reflex to target a wide range of natural and man-made chemicals odours including the biomarkers associated with certain diseases. The training consists in baffling the bees with a specific odour and feeding them with a solution of water and sugar, therefore they associate that odour with a food reward

South India’s first IVF baby in Kerala government hospital

State-owned S.A.T. Hospital here created a record of sorts when it became the first government sector hospital in south India to have test tube babies.

S.A.T. Hospital is the women’s and children’s wing of the Thiruvananthapuram Medical College Hospital.

Head of the fertility clinic Sheela Balakrishnan told reporters the couple who underwent IVF treatment became proud parents of twins, a boy and a girl, at 5.30 a.m. Friday.

“We thus became the fifth government hospital in the country and the first one in south India to be successful. We are expecting another test tube baby next week and then there are five more in various stages,” said Balakrishnan.

In vitro fertilization (IVF) is a process by which an egg is fertilized by sperm outside the body.

IVF is a major treatment for infertility when other methods of assisted reproductive technology have failed.

The process involves monitoring and stimulating a woman’s ovulatory process, removing ovum or ova (egg or eggs) from the woman’s ovaries and letting sperm fertilize them in a fluid medium in a laboratory.

The fertilized egg (zygote) cultured for two-six days in a growth medium and is then transferred to the patient’s uterus with the intention of establishing a successful pregnancy.

Balakrishnan went on to add that since this form of medical procedure is an expensive one, “we operate on a no-profit no-loss basis and the entire cost for couples comes to around Rs.1 lakh”.

In the private sector, the total expense for IVF treatment can touch up to Rs.10 lakh.

The IVF third stage clinic has been in operation for nearly two years.

Children’s cardiovascular fitness declining worldwide

Many kids don’t run as far or fast as their parents did, according to research presented at the American Heart Association’s Scientific Sessions 2013.

The decline in running fitness may indicate worse health in adulthood, the researchers said.

“If a young person is generally unfit now, then they are more likely to develop conditions like heart disease later in life,” said Grant Tomkinson, Ph.D., lead author of the study and senior lecturer in the University of South Australia’s School of Health Sciences.

“Young people can be fit in different ways. They can be strong like a weightlifter, or flexible like a gymnast, or skillful like a tennis player. But not all of these types of fitness relate well to health. The most important type of fitness for good health is cardiovascular fitness, which is the ability to exercise vigorously for a long time, like running multiple laps around an oval track.”

Researchers analyzed 50 studies on running fitness between 1964 and 2010 that involved more than 25 million kids, ages 9 to 17, in 28 countries. They gauged cardiovascular endurance by how far kids could run in a set time or how long it took to run a set distance. Tests typically lasted five to 15 minutes or covered a half-mile to two miles.

Cardiovascular endurance declined significantly within the 46 years, the researchers found. Average changes were similar between boys and girls, younger and older kids, and across different regions, although they varied country to country.

The study is the first to show that kids’ cardiovascular fitness has declined around the globe since about 1975:

In the United States, kids’ cardiovascular endurance fell an average 6 percent per decade between 1970 and 2000.

Across nations, endurance has declined consistently by about 5 percent every decade.

Kids today are roughly 15 percent less fit from a cardiovascular standpoint than their parents were as youngsters.

In a mile run, kids today are about a minute and a half slower than their peers 30 years ago.

Declines in cardiovascular endurance performance are probably caused by social, behavioral, physical, psychosocial and physiological factors, Tomkinson said.

Country-by-country fitness findings are mirrored in measurements of overweight/obesity and body fat, suggesting one factor may cause the other. “In fact, about 30 percent to 60 percent of the declines in endurance running performance can be explained by increases in fat mass,” Tomkinson said.

Kids should engage in at least 60 minutes of daily activities that use the body’s big muscles, such as running, swimming or cycling, he said.

“We need to help to inspire children and youth to develop fitness habits that will keep them healthy now and into the future,” Tomkinson said. “They need to choose a range of physical activities they like or think they might like to try, and they need to get moving.”

More walking tied to lower stroke risk among men

Older men who spend several hours walking each day are less likely to have a stroke than their peers who rarely walk, a new study suggests. And walking pace didn’t seem to matter.

Researchers said few studies have looked specifically at how both walking speed and walking time or distance is linked to stroke risk.

“Stroke is a major cause of death and disability and it is important to find ways to prevent it, especially in older people who are at high stroke risk,” Barbara J. Jefferis told Reuters Health in an email. She led the research at University College London in the UK.

“Our study suggests that maintaining an active lifestyle, specifically by spending more time on all forms of walking, could be an important part of stroke prevention strategies in older people,” Jefferis said.

She and her coauthors analyzed data from men enrolled in a long-term British heart study.

The men entered the study in 1978 to 1980. In 1998 to 2000, when they were in their 60s and 70s, they filled out surveys about how often they were physically active.

The new analysis includes 2,995 men who had not had a stroke or heart disease at the time of that survey. Researchers followed them for another 11 years.

More than half of the men walked an hour or less each day. About one in six reported walking more than two hours per day.

During the follow-up period, 195 of the men had a stroke. The researchers found that the more time men spent walking, the lower their risk of stroke.

Men who walked four to seven hours each week were 11 percent less likely to have a stroke than men who walked for three hours per week or less. But that difference could have been due to chance, Jefferis and her colleagues reported in the journal Stroke.

A stronger finding was that men who walked the most – for more than three hours each day – had a two-thirds lower risk of stroke than those who spent the least time walking.

Walking pace was also tied to stroke risk, such that average-pace or brisk walkers had a 38 percent lower risk of stroke than slow walkers. But distance walked explained that finding: men who walked at an average or brisk pace also walked further than their slower peers, according to the study.

The findings don’t prove walking prevents strokes. But they could not be explained by factors known to increase a person’s risk of stroke, like age, blood pressure and cholesterol. More recently identified markers of stroke, such as proteins associated with inflammation; blood clotting or heart muscle damage also weren’t behind the link.

“What we found was that all of these factors explained only a small amount of the relationship between time spent walking and onset of stroke,” Jefferis said. “This suggests that there may be other factors operating which explain why walking protects against stroke.”

Her team’s study was funded by the National Institute for Health Research and the British Heart Foundation.

Although it only included men, Jefferis said other research has suggested walking is good for women, too.

For instance, a team of Spanish researchers reported late last year that women who walked briskly for at least three and a half hours per week had a lower risk of stroke than inactive women

According to the Centers for Disease Control and Prevention (CDC), close to 800,000 people in the U.S. have a stroke every year, and strokes are the most common cause of serious long-term disability.

“Getting into the habit of walking every day for at least an hour could protect against stroke,” Jefferis said. That can include walking that is done while running errands, walking for leisure in a park or just walking around indoors.

Both the World Health Organization and CDC recommend adults get at least two and a half hours of moderate exercise each week.

Exercise can help kids stave off negative effects of maternal obesity

Researchers have found that off springs whose mothers were fed a high-fat diet during pregnancy and nursing were able to stave off some of the detrimental health effects of obesity by exercising during their adolescence.

It was found that even though the rat offspring weighed the same as their sedentary counterparts, the exercising rats had fewer fat deposits and their brains were better able to respond to a hormone known to suppress the appetite, long after they stopped running on their exercise wheels.

Because mammals (including rats and humans) share much of their biology, the findings suggest that childhood exercise might help mitigate some of the risks that human children of obese parents are biologically primed to follow in their parents’ footsteps and to develop diabetes and other obesity-related disorders.

“Just three weeks of exercise early in life had a persistent effect on the satiety centres of the brains of these rat pups,” study’s lead author Kellie L. K. Tamashiro, Ph.D., an associate professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine, said. “If we can find a way to take advantage of th

at phenomenon in humans that would be great, because preventing obesity is probably going to be much easier to do than reversing it.”

Tamashiro and her colleagues fed pregnant rats a high-fat diet and continued that diet while they were nursing their pups. The animals were weaned on a healthier, standard low-fat diet and at four weeks of age, the equivalent of rodent early adolescence, some were given free access to running wheels in their cages, while the others remained sedentary.

To determine the impact of the exercise on appetite, at 14 weeks of age, the rats’ brains were injected with the appetite-suppressing hormone leptin. Those that had exercised weeks before ate less, while the sedentary rats showed no differences in their appetites.

The study is published in the American Journal of Physiology

Four tips to stay warm this winter

The chill of winters has set in and staying warm has become a priority. We have some pointers here to beat the cold and enjoy this season:

Dress smart

Wear multiple layers of light and warm clothes as it will keep your body heat insulated. Choose clothes made of wool, cotton or fleeced synthetic fibres.

Keep your extremities covered as they are the first parts of your body to lose circulation in cold temperatures. Wear a scarf, mitten and woollen cap when you are heading out.

Eat right

Eat at regular intervals as the burning of food will keep your body warm. Include lots of food items which are rich in protein.

Take hot drinks often to maintain your body temperature.

Move your body

Physical activity helps generate heat and fight cold. Engage in your daily exercise and chores to stimulate blood circulation and also prevent joints and muscles from stiffening.

Use hot water bottle

Stay warm with a hot water bottle. You will find hot water bottles in any department store or you can make one yourself by filling a glass bottle with hot water and wrapping it with a towel.
