Why women take sexy selfies –Researchers

Women take sexy selfies to compete with other women and climb the social ladder in economically unequal environments, new research from an Australian university has found.

A study, published Monday in the Proceedings of the National Academy of Sciences journal, found women took sexy selfies in environments with greater economic inequality, rather than where they might be oppressed because of their gender.

The researchers analysed more than 68,000 sexualized self-portrait photographs, or “selfies,” posted on social media platforms Instagram and Twitter across 113 countries.

They also looked at where in the world the most selfies were taken.

The researchers found the association between sexy-selfie prevalence and income inequality was directly related, with greater sexualisation in environments where incomes are unequal and people are preoccupied with relative social standing.

“We found no association with gender oppression,” the study said.

“It’s all about how women are competing and why they’re competing,” said the study’s lead author, Khandis Blake from University of New South Wales.

She said women are “more likely to invest time and effort into posting sexy selfies online in places where economic inequality is rising, and not in places where men hold more societal power and gender inequality is rife.”

“Selfie” was the Oxford Dictionaries’ word of the year in 2013.

In recent years, especially since the advent of smartphones and social media platforms, the images have become a ubiquitous symbol of the perceived self-obsessiveness of the younger generation.

Researchers in the past have found women take more selfies than men.

The PNAS researchers said income inequality increases competitiveness and status anxiety amongst people at all levels of the social hierarchy, making them sensitive to where they sit on the social ladder and wanting them to do better than others.

“That income inequality is a big predictor of sexy selfies suggests that sexy selfies are a marker of social climbing among women that tracks economic incentives in the local environment,” Blake said.

“Rightly or wrongly, in today’s environment, looking sexy can generate large returns, economically, socially, and personally.”

The researchers found the same pattern of “income inequality” spending in other real world experiences in physical appearance-enhancing areas, like beauty salons and fashion.

“So, when a young woman adjusts her bikini provocatively with her phone at the ready, don’t think of her as vacuous or as a victim,” Blake said.

“Think of her as a strategic player in a complex social and evolutionary game. She’s out to maximize her lot in life, just like everyone.”

North Korean leader Kim Jong-un has tested new ‘high-tech’ weapon in message to the US despite having an agreement with President Trump to denuclearized in the international summit, in June.



North Korea state media is yet to identify the kind of weapon that was launch.

Effects of Hot baths on inflammation, glucose metabolism

Published

on

According to new research, a hot bath could have effects that extend way beyond mental relaxation. According to the authors, regular hot baths might reduce inflammation and improve metabolism.

Over recent years, hot baths, saunas, and other so-called passive heating therapies have received growing attention from scientists.

Scientists now believe they offer some potential benefits, including improved vascular function and sleep.

Because hot baths are low cost and unlikely to cause significant side effects, understanding any benefits that a hot bath might have could be a quick win for medical science.



Recently, researchers set out to understand whether hot bath immersion could have an impact on metabolic disorders, such as diabetes.

 Almost 20 years ago, a paper concluded that hot water immersion of individuals with type 2 diabetes enhanced insulin sensitivity. However, it is still unclear how this might occur.

In the most recent study, the researchers dug a little deeper into the mechanisms at work. They theorized that the influence of a hot bath over glucose metabolism might revolve around the inflammatory response.

Inflammation and insulin resistance

There is some evidence that chronic, low-level inflammation increases insulin resistance. In other words, inflammation reduces a cell’s ability to respond to insulin, potentially contributing to the development of diabetes.

Conversely, exercise has been shown to reduce inflammation and improve insulin sensitivity — meaning that the body has better control over glucose levels.

Although doctors often recommend exercise to reduce the risk of developing metabolic disorders, not everyone can exercise — perhaps due to health conditions or physical capacity. It is, therefore, essential to find alternative ways to improve insulin sensitivity for these people.

Exercise, as with other physical stressors, sparks a brief inflammatory response, followed by a more extended anti-inflammatory response. The researchers wanted to see if a different type of physical stressor — a hot bath — might have a similar effect on the immune system.

For this study, the researchers investigated the impact of a hot bath on overweight, mostly sedentary men. The findings were published recently in the Journal of Applied Physiology.

Hot bath intervention

Each participant immersed themselves in a water bath set at 102°F (39°C) for 1 hour. Scientists took blood just before and after the bath, and then 2 hours later.

Also, the researchers charted the participants’ blood pressure, body temperature, and heart rate every 15 minutes.

 Over the following 2 weeks, the participants had a further 10 hot water immersions.

The researchers found that a single hot water immersion caused a spike of interleukin — a marker of inflammation. Similarly, there was an increase in nitric oxide (NO) production.

The spike in NO is important because it causes blood vessels to relax, lowering blood pressure. NO also improves glucose intake into tissues, and scientists think it has anti-inflammatory properties.



As expected, the 2-week intervention saw a reduction in fasting blood sugar and inflammation. In the same way that exercise influences inflammation, the researchers saw an initial increase followed by a long-term decrease in inflammation.

The researchers also write that it “might have implications for improving metabolic health in populations unable to meet the current physical activity recommendations.”

It is important to note that the people who took part in the study did report some discomfort. This was either due to the length of time that they were required to stay in the bath or the high temperature. Future research might investigate whether shorter periods or lower temperatures might have similar benefits.

Of course, hot baths alone cannot treat metabolic disorders, but they may be a simple, cost-effective intervention that can run alongside other treatments.
