The lockdown, more particularly the alcohol sales ban and economic uncertainty, has dampened the spirits of many South Africans and has affected happiness levels in the country, according to a study by professors at the University of Johannesburg (UJ) and Auckland University of Technology.UJ Professor Talita Greyling and Auckland University's Dr Stephanie Rossouw based the findings of their study, South Africa's Happiness Index, on Twitter posts and analysis of the emotions of South Africans.They found that, the number of Covid-19 cases in South Africa initially reduced happiness levels.READ | 'You've been very good to me' - cheers, tears as Cape Town coronavirus patient is dischargedHowever, levels picked up, possibly because of South Africa's low number of deaths, as people's concerns about the severity of the virus started to ease.What's making us sad?Measures reduced during the lockdown to curb the spread of the virus have also dampened the spirits of South Africans, particularly their inability to move about freely, concerns about the loss of income and the future of livelihoods as well as the ban on alcohol and cigarettes sales.READ | Council for Medical Schemes chairperson dies of Covid-19 complicationsShopaholics out there are also no longer finding joy in buying goods as they once used to."This is a concern: remember that sales drive an economy, if people no longer derive pleasure out of buying, it is a sign that we are moving into unexplored territory, where conventional economic theory no longer holds. "The fact that sales are no longer related to happiness might be due to the concern about future incomes, or maybe the fact that only essential goods can be bought, from which less pleasure is derived, or maybe the experience itself, standing in endless queues to buy essential products," the study indicated.South Africa beyond Covid-19 | We reassessed our hierarchy of needs, and survival always outweighs the rest.
