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

Prof Felicity Burt is from the Division of Virology in the Faculty of Health Sciences at the University of the Free State (UFS), as well as the National Health Laboratory Services (NHLS). She currently holds an NRF-DST South African Research Chair in vector-borne and zoonotic diseases. Professor Burt and her research group investigate arboviruses and zoonotic viruses.
Prof Burt’s research primarily focuses on host immune responses to arboviral infections specifically characterising humoral and cellular immune responses in patients with infections such as Crimean-Congo haemorrhagic fever (CCHF) virus and Sindbis virus; epitope discovery for development of diagnostic tools; development of molecular and serological assays for surveillance purposes; virus discovery; and the development of vaccines.
Raising awareness of these viruses, defining associated diseases, and developing tools for surveillance programmes will contribute to understanding these pathogens as well as the public health implications.
Leads research group in papilloma viruses
Arboviruses cause outbreaks of disease in South Africa annually. Outbreaks are usually associated with heavy rainfall favouring the breeding of mosquitos, but these viruses also have the capacity to spread and become endemic in new areas where competent vectors are present.
In addition, she is leading a research group that investigates human papilloma viruses (HPV) associated with head and neck cancers and recurrent laryngeal papilloma.
The focus of this research group is to ascertain the genotypes of HPV causing these diseases, identification of novel biomarkers for early detection, and complete genome sequencing for molecular characterisation of HPV isolates.
