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

Microbiologist Dr Adepemi Ogundeji has uncovered a new use for an old medicine that can potentially save lives and money. Under the guidance of her study leader, Dr Olihile Sebolai, Dr Ogundeji set out to fight a fungal disease caused by Cryptococcus neoformans. Drs Ogundeji and Sebolai are from the University of the Free State Department of Microbial, Biochemical and Food Biotechnology.
Dr Ogundeji is passionate about education. “My aim will always be to transfer knowledge and skills in the microbiology field,” she said. “Dr Ogundeji’s study is celebrated in that it found a new purpose for existing medicines. An advantage of repositioning old medicines is by-passing clinical trials, which sometimes take 20 years, and the safety of such medicines is already known,” Dr Sebolai, explained.
Cryptococcus infections are difficult to control and often lead to brain inflammation. In layman’s terms: “Your brain is on fire”. People with HIV/Aids are especially vulnerable, surviving only about three months without treatment. Such patients may present with a Cryptococcus-emergent psychosis, and some with an out-of-control inflammatory condition when initiated on ARVs.
Dr Ogundeji found that the clinically recommended dosage of aspirin (anti-inflammatory medicine), and quetiapine (anti-psychotic medicine) is sufficient to control the infection. Her exceptional work was readily published in some of the foremost journals in her field, namely, Antimicrobial Agents and Chemotherapy and Frontiers in Microbiology
