All South African citizens are by now aware of the global pandemic caused by the COVID-19 virus. Our president, Cyril Ramaphosa, placed the entire country in a state of lockdown to limit the spread of the virus in South Africa. Schools, tertiary institutions, churches, and numerous businesses (which do not provide essential services) had to close. The lockdown aims to ensure that citizens stay at home, isolate themselves from others, and that those who can work from home should do so. The consequence and reality, however, is physical and social isolation, which of course also means that many people are currently alone and lonely.

Working from home
There are several benefits to working from home; for example, you can manage your own time, work in comfortable clothes, and you can work undisturbed and with less interruptions. Although the lockdown – and thus social isolation – will only last for (maybe) 21 days, there are psychological disadvantages associated with social isolation. Many people could soon become discouraged and demotivated because of the time away from others due to social isolation. Social isolation is the absence of social interaction, contact, and relationships with loved ones, colleagues, strangers, and even society as a whole. Humans, by nature, are social beings who strive towards social interaction with others, and social interaction is essential for people's well-being and survival. Although it is also natural to occasionally seek alone time, the effect of social isolation can have negative consequences for the emotional well-being of individuals.

Consequences of social isolation
Studies have shown that long-term social isolation has dire consequences for people's physical and mental health, such as increased risk of premature death and higher tendencies towards depression. Still, social isolation – even for a few weeks – can also have a negative psychological impact on people's lives. Social isolation can lead to feelings of despair and loneliness, depression, anxiety, substance abuse, and sleep difficulties. Furthermore, in times of social isolation, individuals tend to exhibit more forms of unhealthy behavior than usual, such as smoking and drinking more alcohol. Feelings of loneliness tend to worsen when individuals are isolated with people with whom they do not have a close relationship and, therefore, loneliness becomes a more significant struggle during times of social isolation. This can turn into a vicious cycle, leading to more loneliness and depression if not dealt with. During these isolation periods, individuals may even become complacent, and consequently do not have goals and routines.

Social isolation will, however, affect people differently. More extroverted people will long for social engagement with others and might feel as if they want to climb the walls. They will just want to go shopping and spend time with others. More introverted individuals may enjoy this alone time and spend time taking long baths and reading books. However, everyone will start to experience social isolation negatively at some point. Families will, for example, not be used to these extended periods together, and this may lead to increased conflict between family members. Individuals with big homes can spend time in their gardens and exercise on their lawns, but what about those individuals living in overcrowded flats or informal accommodations. Such individuals may be more inclined to experience depression, anxiety, and loneliness. Individuals with drinking and smoking habits may become more dependent on these substances during the lockdown. Also keep in mind those individuals who have small children who are now home for several weeks and need to be kept busy and entertained by their parents. Parents are not used to being responsible for keeping their children busy productively.

Socializing through social media
People might still be fine and feel good now, but we have not yet reached the halfway point of the lockdown, and how will individuals cope if the lockdown is extended. There is, of course, hope. It is important to remember that although people are currently isolated, they can still attempt to be social by using various forms of social media. Recent studies have shown that individuals may experience less loneliness when interacting with others through various forms of social media. Accordingly, individuals need to make more contact with others and reach out to those that they have not heard from in a while. Social interaction is crucial, as many of us need social interaction to cope with daily challenges. However, also beware of negative content or fake news. Social interaction via the internet might not fulfil everyone’s needs as with interpersonal communication and interaction, but it still allows us to experience a sense of congregation and community.

Stay positive
The reality is, however, that many people also do not have access to the internet and social media, and therefore cannot communicate with others. It then becomes essential that people should continue with certain routines in their lives and to not just sit in front of the television. People still have to set goals (even smaller goals) for themselves and try to achieve them. Everyone should try to change their perspective by trying to stay positive. People need to attempt any form of exercise and keep their minds occupied with books or brain games. Fortunately, when it comes to children, most schools have provided parents with study material to keep their children busy educationally. Alternatively, parents should create some form of structure and routine for their children during the lockdown. Families can play board games and create their own fun activities. Children should also be allowed to engage with their friends via social media if they become lonely. And parents should allow their children to share their worries and concerns openly. Individuals need to be prepared, because when this mandatory period of isolation ends, everyone will have to resume their normal activities.

Get help
If not addressed, these experiences of overwhelming loneliness, sadness or lack of meaning may continue long after the lockdown has ended. Individuals who experience depression and loneliness after the lockdown should reach out to others, try to eat healthy foods, do fun things, and exercise more. Such individuals should also consider contacting mental healthcare professionals for assistance. They can also visit the South African Depression and Anxiety Group's website or Facebook page for help.

Social distancing is vital at this stage, but as South African citizens, we must remember that we are not going through this alone. We are isolated from others, but together we are all fighting the same battle against COVID-19.

Since his appointment as the South African Research Chairs Initiative (SARChI) Chair, there has been a sharp increase in the number of papers and publications by Prof Hendrik Swart, Senior Professor in the Department of Physics at the University of the Free State (UFS). From January this year, he has already published 78 articles. Some of the journals that has published his work, includes:

• Nanotechnology (impact of 3.67)
• Dalton Transactions (impact of 4.097)
• Sensors and Actuators B: Chemical (impact 3.84)

“My biggest success, however, is the powerful group of researchers we have built over the years. Staff, postdocs and students – without them it would have been impossible. I am therefore much indebted to my groups on both the Bloemfontein and Qwaqwa Campuses.

“The good apparatus we acquired via a sponsorship from the National Research Foundation and Sasol is also one of the main reasons for this. The financial support I get from the university’s research office is of course also a contributing factor,” he says.

For the past 20 years, Prof Swart has been conducting research on any substance that glows. “I only adjust the focus to fit in with current trends,” he says.

Prof Swart believes that his research will make a contribution to the fundamental knowledge about phosphors, as well as to the training of good students for the academic and industrial world on the outside. For the man on the street, his research translates into better, brighter lights that use less energy.

His more recent research focuses on the development of nano-phosphors for light-emitting diodes (LEDS) and organic light-emitting diodes (OLED).

Prof Swart has presented papers on his research not only nationally, but all over the world – including countries in Europe and the East. Some of the most recent papers presented by him and his colleagues/postgraduate students include:

• Applications of AES, XPS and TOF SIMS to phosphor materials at die 15th European Conference on Applications of Surface and Interface Analysis 2013 in Forte Village Resort, Sardinia, Italy.
• Luminescent properties of phosphor nano thin films at the first International Symposium on Nanoparticles/Nanomaterials and Applications in Caparica (Lisbon, Portugal), where he was an invited speaker.
• Role of surface and deep-level defects on the emission of nano metal oxides at the 2014 NanoAfrica international conference, Vanderbijlpark, South Africa, where he delivered the keynote address.
• PHI systems and their modifications at KOVSIES at the PHI European User Meeting in Ismaning (Munich), Germany, where he was invited to speak.

Prof Swart also delivered the keynote address at the SETCOR International Conference on Smart Materials and Surfaces in Bangkok, Thailand. His lecture was titled, ‘Role of surface and deep-level defects on the emission and degradation of phosphor materials’.
