Bad habits are good for health!
We’ve heard lots about bad habits and their negative influence on our organism. But can bad habits be ever useful for us? Yes, researchers say. Sometimes, when doing bad things we actually do good things for ourselves. Here are some examples when negative goes pretty close with the positive.
Anger – good for your blood pressure!
Anger is bad as it can cause the rise of blood pressure but at the same time expression of emotions can let off a head of steam and blood pressure will drop.
Researchers from the Carnegie Mellon University in Pittsburgh have revealed that people who respond to high-stress situations with some righteous anger have lower blood pressure and secrete less cortisol, the stress hormone, than people who respond with fear or hide their feelings inside.
When you demonstrate anger and let off steam you release the stress you’ve accumulated and as a result you develop the feelings of control and optimism. However, when you keep everything to yourself the level of stress hormone rises and you might get a heart disease.
Video games contribute to obesity but boost metabolism as well.
When sitting all day playing video games you can soon become too fat as almost no movements are made during the playing session. But at the same time there is a positive effect as well. The games might help you lose weight.
Scientists at the University of Miami tested 21 boys while those were playing Tekken 3, a mock martial arts contest, on a Sony PlayStation. As the study showed during the game the boys’ heart rates speeded up and they tended to use more energy and breathe more quickly. Of course video games cannot substitute sports but they are more useful that just watching TV.
Swearing eases pain!
Swearing is really bad for people who surround you, but it is good for you as it eases pain.
Scientists at Keele University found volunteers could withstand pain for longer when they use filthy words rather than non-offensive ones.
In the study 64 students had to put their hands in a tub with ice-cold water. They were allowed to use any bad words they liked. The task was then repeated using non-offensive words. As a result volunteers when swore were able to keep their hands submerged for an average 40 seconds longer than when they used normal words. Besides, when the students were questioned about perceived pain they admitted it was lower.
In the volunteers who swore, we also found they had an elevated heart rate, so it could be that swearing increased their aggression levels. Increased aggression has been shown to reduce people’s sensitivity to pain,’ said Dr Richard Stephens, a lecturer in psychology who conducted the research.
Stress improves learning skills and memory
Long-term stress is dangerous for us as it makes us weaker and more prone to various infections. However, a short stressful situation can have quite an opposite effect. We have energy and cognitive skills improved in the result.
All this happens thanks to cortisol, the hormone produced when we’re stressed. It affects the part of the brain which controls learning and emotion. Acute stress increases transmission of glutamate, the substance that passes messages in the brain – and improves working memory.
Zhen Yan, professor of physiology and biophysics, comments:
Stress hormones have both protective and damaging effects on the body. This is why we need stress to perform better, but don’t want to be stressed out.’
And it was rats that helped to discover this ability of our brains. Rats were trained to complete a maze, then half were put through a 20-minute forced swim – that was acute stress. They were then put through the maze again. Scientists revealed that the stressed rats made significantly fewer mistakes when they went through the maze compared to the non-stressed rats.
Housework is hazardous.
Housework can be hazardous. Cleaning and using various types of detergents, especially for pregnant women can lead to the development of allergies and asthma.
A survey that was carried out at Bristol and Brunel Universities revealed that women who used a lot of household cleaning products during pregnancy or shortly after delivering are at a great risk to bring their children to asthma.
The study examined 13,000 children from before birth. The results show that early life exposure to such chemicals is linked to a 41 per cent increase in a child’s chances of developing asthma by the age of seven. The chemicals in these products are supposed to have irritated the child’s airways.
Fidgeting helps lose weight.
Yes, it is irritating and looks terrible but it helps to lose weight. U.S. researchers from the Mayo Clinic have found that people who always seem to be moving are more likely to be slim. The extra motion we all hate in people, that is tapping, twitching, stretching or yawning, burns extra 350 calories a day, or between 10 to 30lb a year.
Endocrinologist James Levine of the Mayo Clinic, who led the research, says:
There are absolutely staggering differences in the amount of fidgeting between people who are lean and people who are obese. The amount of this low-grade activity is so substantial it could account for obesity quite easily.’
So, those who love doing bad things mentioned above can feel relieved as your bad habits can be justified now! Scientists, a big thank you!
