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 Luyt says young researchers should not allow circumstances to determine their future

Young researchers, who spend their life at a disadvantaged and rural campus like the University of the Free State’s Qwaqwa Campus, should not be deterred from achieving their dreams.
This is the view of Prof Riaan Luyt, former Assistant Dean in the Faculty of Natural and Agricultural Sciences, who achieved his B-rating by the National Research Foundation (NRF) late in 2015. This was by far the highest-ever rating on the Qwaqwa Campus.
“When I moved to the Qwaqwa Campus many years ago, having had the opportunity to do a post-doctoral fellowship in Polymer Science at the Leeds University in the United Kingdom, I was determined to get the Department of Chemistry off the ground, and to embark on serious research,” said Prof Luyt, who is now the Affiliated Professor in the Department of Chemistry and Research Associate Professor at the Centre for Advanced Materials, based at Qatar University.
“It was through sheer determination that I managed to obtain enough funds to equip a decent research laboratory. There were many obstacles over the years, but I managed to attract more and more postgraduate students and published more,” he said.
At first, Prof Luyt was not successful with his NRF-rating applications.
“My first couple of attempts to get rated produced no success. I was then awarded a C3-rating, which was later followed by C2 and then C1,” he added. “Getting a B-rating is the highlight of my research career. It shows that it can be done. Young researchers should not allow their past or present circumstances, or their work environment to stand on their way,” said Prof Luyt, who has supervised 38 master’s and doctoral students as well as 11 postdoctoral fellows. He has also published 185 papers in international and accredited journals.
Although abroad, Prof Luyt will continue to supervise eight postgraduate students at the Qwaqwa Campus.
