Tracy looks at the morning's headlines. Students murdered in Nottingham... civilians killed in Ukraine... horrible! She quickly searches for the Positive News website, and sighs with relief. Volunteers saving migrants from the sea... Iceland protecting whales... thank goodness not everything is doom and gloom!

According to a new report by Oxford University's ReutersA major worldwide news agency. Institute, Tracy is typical of many people today. Researchers found that the proportion of those very or extremely interested in the news has dropped from 63% to 48% since 2017. The figure for the UK is even lower: 43%.

The survey, which covers 46 countries, found that young people's interest had plunged even more. In Ireland, the number of 18-to-24-year-olds with a strong interest has fallen from 53% to 28% since 2016.

On top of that, 36% of people said they sometimes or often avoided the news - up from 29% in 2017. One woman is quoted as saying: "Turning my back on news is the only way I feel I can cope sometimes."

In all, 55% were keen to see more positive news stories.

Psychologists are calling this state of mind "headline stress disorder". One, Dr Tal Ben-Shahar, says: "While I don't recommend burying our heads in the sand and ignoring what is going on around us, we should certainly limit our consumption of bad news and expose ourselves to uplifting content."

This could take either of two forms. First, there are the feelgood stories about people doing kind or funny things, or cute videos of animals. Secondly, there is "constructive journalism" which focuses on answers to difficult problems.

Good news helps us emotionally, physically and mentally, says Dr Ben-Shahar: "It can contribute in a meaningful way to a happier and healthier life."

Yes: Depressing headlines give a misleading view of the world. Most of what happens today will be decent, brave and uplifting. Experts say positive news can increase happiness and emotional resilience.

No: News is by definition what is extraordinary, so it is only right that sensational stories - which are often alarming - dominate the headlines. We need to know the worst to appreciate the best.

Or... People need more than peace of mind - they need excitement to stimulate them. The news provides that in abundance: just think of the current political battles in Britain and the US.
