Study claims football fans experience a dangerous levels of stress

If you're a football fan, read this
Football is undoubtedly one of the most loved and popular games around the world. This sport is enjoyed immensely by people across age groups and one can easily get a rough idea about their level of craziness during the Football World Cup or EPL (English Premier League) season. If you have ever got stuck between a Manchester United and Liverpool fan, you will know about the level of dedication and loyalty towards their team.

But a recent study has revealed that this devotion of football fans towards the game might put them at a greater risk of heart attacks due to high-stress levels. 

The study
As per the study carried out by the researchers of the Oxford University, devoted football players experience intense levels of stress while watching their favourite team during a tournament, which can put them at the risk of a heart attack.

The researchers conducted this study during the 2014 Football World Cup when Brazil faced a historic defeat by Germany in the semi-final. For the study, the researchers tested the saliva of Brazilian fans and found that the level of cortisol (stress-related hormones) spiked to a dangerous level during the 7-1 home defeat in the semi-final.

The sudden rise in the stress level can put unnecessary stress on the heart, which can increase your blood pressure and can lead to a heart attack.

Surprisingly, the researchers found no difference in the stress level between men and women. 

The reason
The real reason behind the rise in the stress level is due to the intense involvement of fans in the game. They develop a strong sense of being one with their team, which causes a great impact on their psychology. The ups and downs during a match can also lead to high blood pressure, while prolonged exposure is linked to immune system damage.

The bottom line
Your devotion towards a game is normal, but it is important to understand that it is 'just a game' and winning and losing is a part of the game. Do not let the feeling of defeat fluster you as it can be dangerous for your health. Try to stay calm in all the situations.

Media multitasking may increase obesity risk:

Do you keep switching between digital devices like smartphone, tablet and PC? Beware. A study has linked media multitasking to obesity.

The study showed that mindless switching between digital devices could be associated with increased susceptibility to food temptations and lack of self-control, which may cause weight gain.

“Increased exposure to phones, tablets and other portable devices has been one of the most significant changes to our environments in the past few decades, and this occurred during a period in which obesity rates also climbed in many places,” said lead author of the study.

The research, included 132 participants aged 18-23 years.

The team measured proactive behaviours of compulsive or inappropriate phone use (like feeling the urge to check phone for messages, while talking to someone) as well as passive behaviours like media-related distractions that interfere with your work.

The findings showed those with higher scores were associated with higher body mass index (BMI) and greater body fat percentage.

The participants underwent an fMRI scan during which researchers measured brain activity, while people were shown a series of appetising but fattening foods’ images.

When media multitaskers saw pictures of food, the part of the brain dealing with food temptation became more active, said researchers.

The author said it was important to establish such links given the rising obesity and prevalence of multimedia use.

Watching television for more than three to four hours a day is linked to eight leading causes of death, including cancer, heart disease and diabetes, in the U.S., researchers say.

Previous studies had reported a relationship between TV viewing and an elevated risk of death from cancer and cardiovascular disease. In this study, researchers at the National Cancer Institute in the U.S. looked at more than 2,21,000 individuals in the 50-71 age group who were free of chronic disease at study entry. They confirmed the association with higher mortality risk from cancer and heart disease.

In addition, they identified new associations with higher risk of death from most of the leading causes of death in the U.S., such as diabetes, influenza/pneumonia, Parkinson’s disease and liver disease.

“We know that television viewing is the most prevalent leisure-time sedentary behaviour and our working hypothesis is that it is an indicator of overall physical inactivity,” said lead investigator Sarah K. Keadle from the U.S. National Cancer Institute.

“In this context, our results fit within a growing body of research indicating that too much sitting can have many different adverse health effects,” Ms. Keadle said.

The study found that compared to those who watched less than one hour of TV a day, individuals who reported watching three to four hours were 15 per cent more likely to die from any cause.

Those who watched seven or more hours were 47 per cent more likely to die over the study period. Risk began to increase at three to four hours for most causes they examined. — PTI

Watching activity video may boost your brain power

Watching video of simple tasks before carrying them out may boost the brain’s structure, or plasticity, and increase motor skills, according to a new study.

Brain plasticity is the brain’s ability to flex and adapt, allowing for better learning. The brain loses plasticity as it ages.

For the study, 36 right-handed healthy adults participated in 40-minute training sessions five times a week for two weeks. Half the group watched videos of a specific task, such as writing with a pen, cutting with scissors or handling coins, then were asked to complete the task themselves.The other half watched videos of landscapes and then were asked to complete the same tasks.

At the start of the study and again two weeks later, the groups were tested for strength and hand skills, and also underwent 3-D MRI brain scans. Scientists looked at brain volume changes in both groups.

The study found that the group who completed the training along with watching the activity videos had 11 times greater improvement of motor skill abilities, mainly in terms of strength, compared to those who watched the landscape videos.

“Our study lends credence to the idea that even as an adult, your brain is able to better learn skills just by watching the activity take place. With a dramatic increase of videos available through mobile phones, computers, and other newer technology, this topic should be the focus of more research,” said study author Paolo Preziosa, with San Raffaele Hospital in Milan, Italy.

“The results might also contribute to reducing disability and improving quality of those who are impaired or who are undergoing physical rehabilitation,” Preziosa said. The study will be presented at the American Academy of Neurology’s Annual Meeting in Philadelphia.
