Baby Breastfeeding Make Orgasm

Orgasm is usually associated with sexual activity, but many women report feeling the excitement when she was breastfeeding her baby. Some women even report the experience of orgasm during or after feeding.In a study conducted in nursing mothers, as much as 40.5 percent of participants reported having felt aroused several times during breast-feeding a baby. A total of 16.7 percent even reported sexual arousal often feel when breastfeeding her baby. 

And in more recent papers from some of the study, noted that 33-50 percent of mothers breast-feeding had an orgasm, even though 25 percent of those surveyed feel guilty. Guilt arises because women are usually considered inappropriate when a mother, stimulated by her own baby. Of course not all the mothers who breastfeed experience of sexual arousal. In fact there are many women who think that the experience as opposed to pleasure. 

What causes a nursing mother can orgasm? 

According to researchers this is caused by oxytocin, the hormone that stimulates milk expenditures and triggered by breast stimulation. 

The hormone oxytocin is also involved in other physiological processes, especially in uterine contractions during childbirth and during orgasm. This hormone is also thought responsible for the feeling of relaxation and experience orgasm without sexual stimulation, like an orgasm when you feel full.

Be Careful, Vitamin E Can Make Osteoporosis

Vitamin E is contained naturally in many foods such as vegetable oils, nuts and leafy vegetables. This vitamin is believed to be efficacious as an antioxidant, maintaining health and slowing the aging process. Unfortunately, a study found that vitamin E can lead to bone loss. 

Researchers led by Shu Takeda from Keio University in Tokyo, said the findings are a warning for people who take supplements of vitamin E. Takeda confirms that vitamin E can stimulate cells that cause bone loss or osteoporosis. 

Osteoporosis is a disease that causes thinning of bone tissue and loss of bone density over time so that the person is prone to fractures. The disease is common in older people, especially women. 

The researchers explained that maintaining a balance between bone-forming cells (osteoblasts) and bone destructive cells (osteoclasts) would make the bones stronger. Previous research suggests that vitamin E is beneficial for bone health. However, researchers from Japan discovered the contrary, vitamin E actually trigger the production of bone destructive cells. 

"A healthy bones consist of a dynamic network. To maintain this condition, the necessary balance between osteoblasts and osteoclasts. Understanding the competition of these cells is very important to understand how vitamin E affects bone health," said Dr. Robert Graham, an internist at Lenox Hill Hospital in New York City. 

Research published in the journal Nature Medicine found that vitamin E-deficient mice have higher bone mass because it has less bone damage. Meanwhile, healthy rats that were fed vitamin E with the same levels as found in human supplementation decreased bone mass by 20% within eight weeks. 

Takeda Research also shows that vitamin D can increase bone formation, but vitamin E is the opposite. However, further research is needed to better understand how vitamin E works in humans. 

"Before we started telling people to dispose of its vitamin E supplements, let me state that the results obtained from studies in rats and further research is needed to view the risks and benefits in humans," said Graham.

Less Sunlight Can Increase Risk of Stroke

It has long been known that exposure to sunlight is sufficient to nourish the body. New research shows that the amount of sun exposure may play a role in determining the risk of stroke. "We heard a lot about how the sun may be bad for the body, for example in terms of skin cancer. But in sun exposure studies indicate that there may be some positive outcomes associated with exposure to sunlight," says Leslie McClure, a professor of biostatistics at the University of Alabama , Birmingham. 

Prof. McClure and his colleagues will present their findings on February 6, 2012 meeting of the American Stroke Association in New Orleans. To explore the possible connection between the sun and stroke, researchers analyzed data collected from an ongoing study involving more than 30,000 black men and white women over the age of 45 years.

The research team focused on the approximately 16 500 participants, which none had a history of stroke or heart disease when they were enrolled in this study. The study took place between the years 2003-2007. All study participants underwent a physical examination. In addition, all study participants completed questionnaires about their medical history and where they had lived in the past. During follow-up for 5 years, some 351 of 16 500 had a stroke. 

The results showed that those who have a range of low sun exposure risk 1.6 times more likely to suffer a stroke than those getting more sun exposure.The research team also found evidence that those who live in areas with cold climates also showed a higher risk for stroke.

"We still do not know what causes sun exposure associated with risk of stroke. There are many hypotheses, but we really do not understand the mechanism," said Prof. McClure. Areas with exposure to sunlight may also have low vitamin D levels. Low levels of vitamin D have been associated with higher risk for stroke. Other studies also revealed that people who consume more vitamin D had 11 percent lower risk of stroke.
