25 minutes are all you need to stay healthy

25 minutes are all you need to stay healthy


A research has revealed something all of us know but choose to ignore -- it doesn't take a lot to stay fit.
Researchers have said that older people who undertake at least 25 minutes of moderate or vigorous exercise everyday need fewer prescriptions and are less likely to be admitted to hospital in an emergency.

The findings reinforce the need for exercise programmes to help older people stay active. It could also reduce reliance on NHS services and potentially lead to cost savings.
In the first study of its kind looking at this age group, researchers from the University of Bristol looked at data from 213 people whose average age was 78.
Those who carried out less than 25 minutes of moderate to vigorous physical activity per day -- such as walking quickly, cycling or swimming -- received 50 per cent more prescriptions over the following four to five years than those who were more active.
The study also found that being physically active reduced the risk of unplanned hospital admissions.
Those who were in the most active third of the sample were on average achieving 39 minutes of moderate-to-vigorous activity and were at half the risk of emergency hospital admissions than those in the low active group.
Researchers measured physical activity using accelerometers -- small gadgets that monitor all movement throughout the day -- alongside elements of physical function including balance, leg strength and walking gait.
The findings have been published in the journal PLOS ONE.

Too Much Porn Can Shrink Brain: Study

Too Much Porn Can Shrink Brain: Study




Watching sexually explicit videos regularly may cause the brain to shrink and work less effectively , a new study has claimed. The study suggests that the brains of heavy porn users show signs of degradation and shrinkage. 

Porn

Researchers at the Max Planck Institute for Human Development in Berlin found that men who watch a lot of porn tend to have a smaller striatum, an area of the brain "linked to rewards and motivation." They also found that the connection between the striatum and the prefrontal cortex — the part of the brain associated with behaviour and decision making — degraded with increased porn watching, 'The Telegraph' reported. 

They also found that the connection between the striatum and the prefrontal cortex - the part of the brain associated with behaviour and decision making degraded with increased porn watching, 'The Telegraph' reported.
Although the study suggests that porn causes the brain to shrink, researchers cautioned it could be that people with smaller brains are more attracted to porn.

Pornography consumption was associated with neural structure, task-related activation, and functional resting-state connectivity.
Gray matter volume of the brain as measured by voxel-based morphometry and resting state functional connectivity was measured on magnetic resonance imaging scans.
"We found a significant negative association between reported pornography hours per week and gray matter volume in the right caudate as well as with functional activity during a sexual cue–reactivity paradigm in the left putamen," researchers wrote in the journal JAMA Psychiatry.
"Functional connectivity of the right caudate to the left dorsolateral prefrontal cortex was negatively associated with hours of pornography consumption," they said.

For the study, sixty-four healthy male adults with a broad range of pornography consumption reported hours of pornography consumption per week. "We found a significant negative association between reported pornography hours per week and gray matter volume in the right caudate," researchers said.

Heavy porn consumption may shrink your brain


Watching porn may not only lead to divorce but can also reduce your brain size.
German researchers have found less gray matter in brains of men who consumed sexually explicit material heavily.
"Our findings suggest that gray matter volume of the right caudate of the striatum (a subcortical part of the forebrain) is smaller with higher pornography use," said the study.
To analyse the impact of porn on brain, researchers questioned 64 men aged 21-45 about their porn-watching habits and scanned their brains with MRI technology.
"The results show that the brain region activated when people view sexual stimuli is less active in men who watch a lot of pornography," explained lead author Simone Kohn from the Max Planck Institute for Human Development in Berlin.
It is the first link between porn consumption and reductions in brain size and brain activity in response to sexual stimuli.
"It is not clear from the findings whether watching porn leads to brain changes or whether people born with certain brain types watch more porn," Kohn noted.
The study was published in the journal JAMA Psychiatry.


Watching pornography could be shrink parts of the brain linked to reward and motivation.This is according to a German study that found men who watched a lot of porn tended to be lazier. The results provide the first direct link between pornography and a lack of motivation following sexual stimulation

(7)Eating seven+ portions of fruits and veggies daily cuts your risk of death nearly in half


Your momma always told you to eat your veggies. Little did you know that she was so very right. Science has now backed up our mothers’ claims that eating fruits and veggies is good for us. In fact, according to this unique study, eating seven or more servings of fruits and veggies can reduce your risk of death in general by 42%.
Now I said the study was unique. What makes it so?
This is the first study to link fruit and vegetable consumption with all-cause, cancer and heart disease deaths in a nationally-representative population, the first to quantify health benefits per-portion, and the first to identify the types of fruit and vegetable with the most benefit.
Ok, so this seems legit, right? What are the actual findings? What if you only eat a few servings, not seven? The study is thorough:
Compared to eating less than one portion of fruit and vegetables, the risk of death by any cause is reduced by 14% by eating one to three portions, 29% for three to five portions, 36% for five to seven portions and 42% for seven or more.
But don’t rush off to the store yet. There’s more. If you want benefits, you’ve got to eat the good stuff. Canned and frozen fruit actually increases your risk of death by 17%. The study is a bit sloppy here, so it’s hard to tell what actually causes in the increase––is it just canned fruit, perhaps because of the sugar? Or is it the fault of overall poor health of populations who eat those fruits? While we may not know, the overall point is clear: Go eat fruit and veggies!

(Reuters) - A group of 53 leading scientists has warned the World Health Organization not to classify e-cigarettes as tobaccoproducts, arguing that doing so would jeopardize a major opportunity to slash disease and deaths caused by smoking.
The UN agency, which is currently assessing its position on the matter, has previously indicated it would favor applying similar restrictions to all nicotine-containing products.
In an open letter to WHO Director General Margaret Chan, the scientists from Europe, North America, Asia and Australia argued that low-risk products like e-cigarettes were "part of the solution" in the fight against smoking, not part of the problem.
"These products could be among the most significant health innovations of the 21st century – perhaps saving hundreds of millions of lives. The urge to control and suppress them astobacco products should be resisted," the experts wrote.
Leaked documents from a meeting last November suggest the WHO views e-cigarettes as a "threat" and wants them classified the same way as regular tobacco products under the Framework Convention on Tobacco Control (FCTC). (link.reuters.com/muq69v)
That has set alarm bells ringing among a number of medical experts - and in the booming e-cigarette industry. A total of 178 countries are parties to the international convention and are obliged to implement its measures, with the United States the one notable non-signatory.
A move to classify e-cigarettes alongside regular cigarettes would push countries into taking similar tough measures to restrict demand, including raising taxes, banning advertising, introducing health warnings and curbing use in public places.
Uptake of electronic cigarettes, which use battery-powered cartridges to produce a nicotine-laced inhalable vapor, has rocketed in the last two years and analysts estimate the industry had worldwide sales of some $3 billion in 2013.
But the devices are controversial. Because they are so new there is a lack of long-term scientific evidence to support their safety and some fear they could be "gateway" products to nicotine addiction and tobacco smoking - though the scientists said they were "unaware of any credible evidence that supports this conjecture".
In response to the scientists' letter, Penny Woods, chief executive of the British Lung Foundation, said: "The overall impact of e-cigarette use on public health is currently unclear. While they could prove to be an important tool to help people stop smoking, the unregulated status of e-cigarettes is problematic."
BIG TOBACCO BACKS SCIENTISTS
For tobacco companies seeking to offset the decline in traditional smoking, investment in e-cigarettes was an obvious choice and all the major players now have a presence, prompting Big Tobacco to line up behind scientists on this occasion.
Kingsley Wheaton, director of corporate and regulatory affairs at British American Tobacco, said classifying e-cigarettes as tobacco products would mean smokers find it harder to access a less risky alternative.
In a declaration of interests, none of the scientists said they had received funding from tobacco companies. However, some have carried out research on e-cigarettes or acted as consultants for drug companies making other smoking cessation products, includingGlaxoSmithKlineJohnson & Johnson and Pfizer.
The Geneva-based WHO said its position on e-cigarettes was still in flux ahead of a key meeting on the FCTC scheduled for October 13-18 in Moscow, where proposed regulations will be discussed.
"At this point the only thing I can say is that we are elaborating these regulations and they will soon be available to you," Armando Peruga, program manager for the WHO's Tobacco Free Initiative told reporters this week.
Gerry Stimson, emeritus professor at Imperial College London and one of the organizers of the letter to Chan, told Reuters that the WHO's position was "bizarre" and its stance on e-cigarettes was harsher than that of regulators in Europe and the United States.
"We want to make sufficient noise now before things get too set in stone," he said.
