Loosen Up Your Back, Hamstrings

This asymmetrical forward bend will stretch each side of your back and your hamstrings (backs of your thighs) separately. You may find that one leg or one side of your back is tighter than the other. Spend extra time stretching the tighter side.

1. Kneel on a padded surface. Bring your right foot in front of you. Bend your knee slightly and rest your right heel on the floor with your toes pointing up. Hinging at the hips, bend forward and balance on your fingertips. Lengthen your spine by reaching the crown of your head away from your tailbone. Slowly straighten your right knee. Hold this position for 10 to 20 seconds and repeat on the other side or move on to the next pose.

2. Keeping your lower body in the same position, shift your weight over your left hand. Place your left hand flat on the floor below your left shoulder. Once you feel stable, turn your upper body to the right and raise your right hand directly above your right shoulder. Focus on sliding your shoulder blades down away from your ears. Hold for 10 to 20 seconds, then turning toward the floor, bring your hand down. Repeat on other side.

Inversion Exercise


Kneel with your forearms and palms on the floor, shoulder‘s width apart. Spread your fingers. Straighten your legs and walk in until your heels are on the floor and your knees are straight.

Step 2:

Keep your head and shoulders lifted away from the floor. Slowly shift more weight to your right leg and begin to raise your left leg. Focus on keeping your hips and shoulders facing the floor. Pause for three breaths. Lower your leg and repeat on the other side.

Do three sets of the above exercise and take little rest.

Inversions take weight away from the legs and improve circulation. If done on a regular basis, they will enhance your concentration skills by bringing more blood flow to the brain. Use this simple inversion move to become familiar with the correct positioning.

Miracles of Vitamine ‘D’

[amazon_link asins=’B01E4JIODM,1514875535,B008S0LH6K,1500528137,B016X6MJGM,1491243821,0399594442,0060984368,B00DKF7XPW’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’e5482c5b-f7ab-11e7-96e8-25d473280400′]

US researchers have discovered that Vitamin D protects not just against rickets, osteomalacia and osteoporosis but also against heart diseases, cancer, diabetes and other ailments.


Medical researchers are homing in on a new wonder drug that can significantly reduce the risk of heart disease, cancer, diabetes and many other diseases — sunshine

A recent study found that men who are deficient in the “sunshine vitamin”, vitamin D, have more than double the normal risk of suffering a heart attack. Another study last week found that low levels of vitamin D increase the risk of diabetes, and a study last month linked deficiencies to an increased risk of dying from breast cancer.

The new findings join a growing body of evidence indicating that an adequate level of the vitamin, which most people can get from 20 daily minutes in the sun, is crucial to maintaining good health.

Not every scientist agrees, and there is controversy about what should be considered an adequate level of vitamin D in the blood. But sentiment gradually is shifting toward a higher intake.

“We don’t have a cause-and-effect relationship here yet,” said biochemist Hector DeLuca of the University of Wisconsin, in the US, to prove that higher doses of vitamin D prevent these diseases. DeLuca was the first to demonstrate how the vitamin interacts with the endocrine system, which manages the body’s hormonal balance.

But the links are so suggestive “that we have to pay attention to keeping blood levels up where they will protect,” he said. Until the protective effect is proved, he added, “what’s wrong with keeping an adequate level of vitamin D in the blood in case it is?”

Until recently, vitamin D was viewed primarily as a protective agent against diseases of the bone, such as rickets, osteomalacia and osteoporosis. Recommendations for the vitamin are based on preventing these disorders and call for a relatively small intake — a minimum of 400 international units (IUs) per day and perhaps twice that for elderly people, who don’t get outdoors much.

The vitamin is produced from natural precursors in the body by exposing skin to ultraviolet B in sunlight. Caucasian sunbathers can get 20,000 IUs in 20 minutes at noon in summer. But any additional exposure simply damages the skin.

Darker skinned people need three to five times the exposure to produce the same amount. Sunblock interferes with production by screening out ultraviolet light.

The primary sources of vitamin D in the diet are milk, which is fortified to yield about 100 IUs per glass, and oily fishes, which have a high content. To have an adequate intake, most people must take supplements or spend more time in the sun — a recommendation that dermatologists generally oppose because of the risk of skin cancer.

Current guidelines call for blood levels of about 30 nanograms per millilitre. By that definition, perhaps 10 per cent to 15 per cent of the white US population and 50 per cent of the black population is deficient in summer, with levels rising in winter when there is less sunlight.

Many researchers now say we should be striving for average blood levels of 50 to 60 nanograms per millilitre, at which level the bulk of the US population would be considered deficient.

Most researchers in the field take supplements of at least 1,500 IUs per day. Most recommend taking no more than 4,000 IUs because of potential toxicity.

Experts attribute the vitamin D deficiency, in part, to modern lifestyles. Video games and computers have brought children indoors, minimising their exposure to sunlight. Fear of cancer and increasing use of sunblock also might have contributed.

In the new analysis, Dr Edward Giovannucci of the Harvard School of Public Health and his colleagues studied 18,225 men enrolled in the Health Professionals Follow-Up study, a subgroup of a much larger ongoing study. The men submitted blood samples when they enrolled in the study, mostly in 1993 to 1995, and the samples were stored.

In 10 years of follow up, the team identified 454 men who had a nonfatal or fatal heart attack. They matched these men with about 900 other study members who did not have an attack, then measured vitamin D levels at study entry.

They reported in the current issue of the Archives of Internal Medicine that men with blood levels below 15 nanograms per millilitre had two and a half times the risk of having an attack or dying. When they controlled for all other possible factors, such as hypertension, obesity and high lipid levels, the risk was still twice as high as it was for the controls.

Men with levels between 15 and 29 nanograms per millilitre also had an increased risk. Unfortunately, Giovannucci said, there were not enough men in the group with levels above 35 nanograms per millilitre to determine whether higher levels are more protective.

The findings are “not out of left field”, he said. Many epidemiological studies have found a lower rate of heart attacks at higher latitudes, at lower altitudes and in winter — all of which correlates to decreased exposure to sunshine.

“They certainly have made the link between diabetes and cardiovascular disease,” said Dr Mason Weiss, a cardiologist at Centinela Hospital Medical Centre in Inglewood, California, who was not involved in the study. “Now the research must be on what the mechanism is.”

Giovannucci speculated that several mechanisms could be responsible for the observation. Previous studies have suggested that low vitamin D levels lead to a build-up of calcium in atherosclerotic plaques on the walls of arteries, increasing the risk of heart attacks.

It also could affect blood pressure or the functioning of heart muscles, making them more susceptible to arrhythmia.

“We obviously need to understand the mechanism better,” Giovannucci said. “But that requires randomised trials, which is a big undertaking.”

Weiss joined the chorus of researchers calling for changes in federal guidelines to reflect the new data.

“The next time they review the daily requirements, they should look at all these articles,” he said. Increasing the recommended intake of vitamin D “could have a significant health benefit,” he said, and would be a very cost-effective change.

Kids of smoking parents have more nicotine

[amazon_link asins=’B00VH95OMM,B0799K8VNV,B000NHSALG,B07CWJRC57,B07B4YFXYM,1939267838,B075GPM75V,B071LP3HGK,B06XSGXLJC’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’28113b36-8e17-11e8-91b7-7950fa699f44′]

A new study has found that children, who have at least one smoker parent, have 5.5 times higher levels of cotinine, a byproduct of nicotine, in their urine.


The study, published online ahead of print in Archives of Disease in Childhood, showed that having a smoker mother had the prime independent effect on cotinine in the urine – quadrupling it. Having a smoking father doubled the amount of cotinine, one of chemicals produced when the body breaks down nicotine from inhaled smoke to get rid of it.

The study was led by researchers from the University of Leicester Medical School and was done in collaboration with Warwick University.

Sleeping with parents and lower temperature rooms were also linked to increased amounts of cotinine.

Cotinine was measured in 104 urine samples taken from 12-week old infants. Seventy one of the babies had at least one parent that smoked and the parents of the other 33 were non-smokers.

“Babies affected by smoke tend to come from poorer homes, which may have smaller rooms and inadequate heating. Higher cotinine levels in colder times of year may be a reflection of the other key factors which influence exposure to passive smoking, such as poorer ventilation or a greater tendency for parents to smoke indoors in winter,” the authors said.

Sleeping with a parent is a know risk factor for cot death and the authors suggest that one reason for this could be breathing of, or contact with clothing or other objects contaminated with, smoke particles during sleep.

Nearly 40 percent of under-fives are believed to be exposed to tobacco smoke at home, and smoke may be responsible for up to 6,000 deaths per year in the US alone in young children.

“Babies and children are routinely exposed to cigarette smoking by their caretakers in their homes, without the legislative protection available to adults in public places,” the authors said.

But they admitted that there are realistic difficulties in preventing smoking in private homes because it relies on parents or caretakers being educated about the harmful effects of passive smoking on their children and then acting on that knowledge.
