Arina Engelbrecht from Organisational Development and Employee Well-being believes physical activity has a number of benefits for one’s health, including stress relief.
Being physically active plays a big role in preventing the development of mental-health problems and in improving the quality of life of people experiencing mental-health problems.
Treatment for depression
Physical activity can be an alternative treatment for depression. It can be used as a stand-alone treatment or in combination with medication and/or psychological therapy. It promotes all kinds of changes in the brain, including neural growth, reduced inflammation, and new activity patterns are formed that promote feelings of calm and well-being. It releases endorphins – powerful chemicals in the brain that energise your spirit and make you feel good.
Physical activity can be very effective in relieving stress. Research in adults has found that physically active individuals tend to have lower stress levels compared to individuals who are less active. It also leads to improved sleep. When a person sleeps better and feels more rested, overall quality of life improves. They cope better with daily life stressors.
Reduce Alzheimer's risk
Regular physical activity can reduce your risk of developing Alzheimer's disease by up to 50%. It can also slow down further deterioration in those who have already started to develop cognitive problems. It stimulates the brain’s ability to maintain old connections as well as to make new ones.
A study asked people to rate their mood immediately after periods of physical activity (e.g. going for a walk/run, cycling, doing housework) and periods of inactivity (e.g. reading a book or watching television). Researchers found that participants felt more content, more awake, and calmer after being physically active compared to after periods of inactivity.
In conclusion, people who are physically active feel a sense of well-being, feel more energetic throughout the day, sleep better at night, have sharper memories, and feel more relaxed and positive about themselves and their lives.
“Being physically active not only changes your body, it changes your mind,
attitude, and your mood.” – Arina Engelbrecht
#Women'sMonth: Lack of HIV education still affects children

“Despite all the advances in the management and prevention of HIV, children still become infected every day, often due to lack of education and access to health care.” This is according to Dr Nickie Goedhals, Senior Lecturer and Pathologist in Medical Microbiology and Virology at the University of the Free State (UFS).
Study published in UK medical Journal
A case study she was part of and published in the UK medical journal The Lancet in 2012, demonstrates the transmission of HIV to a child through surrogate breastfeeding. This study is one of the many highlights in the young researcher’s career. She received her first rating from the National Research Foundation (NRF) in 2017 for the work she has done in Medical Virology over the past eight years.
According to the above-mentioned study, only about 1% of infants in South Africa are being breastfed by a surrogate. However, results from a study in the Free State showed that shared breastfeeding by a non-biological caregiver was the most important factor associated with HIV infection in discordant mother-child pairs. Therefore, continued education about the risk of HIV transmission is needed.
Dr Goedhals is also continuing with research on HIV by looking at HIV drug resistance. She is in the process of starting new projects focusing on HIV infection and drug resistance in infants.
PSP helped with NRF-rating
She says, although her NRF Y2-rating is the starting point of a research career, it shows that she is heading in the right direction, and it “gives access to research funds through the NRF for future projects.” Other important research she conducted was on Crimean-Congo haemorrhagic fever – the study for her PhD.
The Prestige Scholars Programme (PSP) at the UFS is the reason that she applied for the rating. “With all the service delivery, teaching, and administrative responsibilities of academic medicine, it is easy to lose focus. The PSP has really helped to create a focused and stimulating environment for research.” According to her, the PSP also provides access to a network of peers and senior staff at the UFS, as well as exposure to national and international experts.
