Sitting has been called the new smoking for its supposed Public health risks, especially for people with sitting down office jobs. Over the past 15 years or so sitting has been connected with heart disease and diabetes (糖尿病). But is sitting really that risky?
In our latest study we examined if not only the total amount of sitting, but different types of sitting, were connected with developing type 2 diabetes. We wanted to see if there was any difference among sitting watching TV, sitting at work, or sitting at home but not watching TV.
We studied sitting habits of 4. 811 middle-aged people, who didn't have diabetes or heart problems at the start of the study. Over the next 13 years, 402 people developed diabetes. Once we considered obesity (AE RF), Physical activity, and other things that may develop type 2 diabetes, neither total sitting time, sitting at work nor sitting at home but not watching TV were connected with developing diabetes. We found only a weak connection with the time spent sitting watching TV and an increased risk of developing diabetes.
This is different from the results of five older TV studies that showed a stronger connection. But hardly any of the included studies mentioned obesity, a major cause of diabetes.
For people who are physically inactive, though, the story's different. Two recent studies show the total time spent sitting a day is connected with developing diabetes, but only in people who are physically inactive or both physically inactive and obese.
That's not the whole story. At least two things determine if sitting is a risk factor in its own right: the type and situation of sitting.
For example, sitting down at work isn't strongly connected with long-term health risks, Perhaps that's because higher position jobs needs more sitting, and higher socioeconomic (社会经济) position is connected with a lower risk of disease. It's a different case for sitting watching TV, the type of sitting most possibly connected with long-term health risks. People who watch a lot of TV tend to (a) be of lower socioeconomic positions, unemployed, have poorer mental (精神上的) health, eat unhealthy foods and face more unhealthy food advertising.
Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.
{#blank#}1{#/blank#} Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.
For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. {#blank#}2{#/blank#}
Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.
{#blank#}3{#/blank#} They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “{#blank#}4{#/blank#} Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”
Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. {#blank#}5{#/blank#}
