Do you suffer from cybersickness It causes nausea while scrolling on phones

The rise of mobile phones has been blamed for a number of social ills, but your smart phone may also be making you physically sick as well. Scientists have identified a condition called “cybersickness”, which they say is the digital version of motion sickness. The phenomenon, which affects up to 80 percent of the population who own smartphones or tablets, leads to feelings of nausea and unsteadiness. It is caused by seeing fast motion on a screen and covers anything from a car chase in a film to scrolling through web pages on your phone. The more realistic the visual content is, the higher your chances of getting cybersickness. The condition was identified in a piece in the New York Times in which British and US experts said that it needed addressing. Cyriel Diels, a cognitive psychologist and human factors researcher at Coventry University’s centre for Mobility and Transport, said: “It’s a fundamental problem that’s kind of been swept under the carpet in the tech industry.” “It’s a natural response to an unnatural environment.” Motion sickness leaves sufferers feeling ill because they feel movement in your muscles and your inner ear but do not see it. The mismatch in digital sickness is the oppositeyou see movement on the screen but do not feel it. The effect is the same and the symptoms include a headache, wanting to throw up, confusion and the need to sit down. Often cybersickness manifests itself in a subtle way and sufferers put it down to stress or eyestrain.Steven Rauch, a professor of otolaryngology at Harvard Medical School, said: “Your sense of balance is different than other senses in that it has lots of inputs.” When those inputs don’t agree, that’s when you feel dizziness and nausea “Some studies that have been carried out into cybersickness found that women are more susceptible than men, the New York Times reported. Those who have Type A’ personalitiesmeaning they are confident and assertiveare more likely to suffer from cybersickness as well. Among those who have reported experiencing the condition have been video gamers who spend hours playing fast paced games. Cinema-goers have struggled with some scenes in action movies which have quick cuts and fast editingand virtual reality has made the problem even worse. Jonathan Weinstein, a professor at the Kanbar Institute for Film and Television at New York University’s Tisch School of the Arts, said: “The idea is to get audiences to feel like participants in the action rather than outside observers of the action. Engineers at Oculus VR, the virtual headset manufacturer, have admitted that digital motion sickness is one of their biggest problems.

In modern society, drugs are becoming a more and more serious problem in the world. The trade of drugs is widespread, which costs up to $800 billion every year.

As we all know, drugs do great harm to our health, not only causing people to die at an early age,but also directly contributing to the happening of crimes. As is shown on the chart above, 30% of the teenagers taking drugs are cheated into doing it, and 50% are driven by curiosity. Another 15% just seek excitements or try to get rid of their anxieties, and the rest try it for some other reasons.

In my opinion, in order to protect us students from drugs, we should be careful to make friends and stay away from those who always behave badly. Also, it's very important for us to lead a healthy lifestyle and hold positive attitudes towards life.

Can money buy happiness? Various people have various answers. Some people think that money is the source of happiness. With money, one can buy whatever he enjoys. With money, one can do whatever he likes. So, in their minds, money can bring comfort, security, and so on. Money, as they think, is the source of happiness.

But there are still a lot of others who think that money is the root of all evil. Money drives people to steal, to rob, and to break the law. A lot of people became criminals just because they were in search of money. And in the Western countries, there is nothing that can’t be bought by money. Many people lose their own lives when hunting it.

I think that money is essential to life and we cannot do without money. But even though money is necessary to life, it can’t buy happiness. Happiness is not something that can be measured by money. It is a state of mind. One can have plenty of money, with which he can buy whatever he wants, and at the same time he is not happy because he is never satisfied or he is troubled by various kinds of problems. Therefore, although money is necessary for a happy life, it can’t buy happiness.
