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

UFS on energy-saving mode
2009-09-15

The University of the Free State (UFS) has undertaken several measures to reduce energy consumption on the Main Campus in Bloemfontein.

“Part of Eskom’s strategy is that all the main universities must reduce their electricity consumption. Because the university is the second biggest user of electricity in Bloemfontein we have to cut our consumption according to the new energy policy,” said Prof. Niel Viljoen, Chief Director of Operations at the UFS.

“Electricity is also expensive and if we look at global warming and everybody’s responsibility, I think we all have a moral obligation to save energy,” said Prof. Viljoen.

“The energy crisis of January 2008 and beyond, with its load-shedding limitations, was a major driver for the government to introduce the Power Conservation Scheme,” said Mr Anton Calitz, the UFS’s electrical engineer.

The measures put in place by the UFS include amongst others:

The introduction of a solar water-heating system in the residences, which is a first of its kind in Bloemfontein.
An investigation is also being launched into alternatives and the effective heating of rooms in the residences.

Feasibility studies are currently being conducted to determine whether energy saving can be achieved with radiation panels.

Energy-saving lights have been installed in the following buildings: the Architecture Building, Genmin Lectorium, Geology lecture halls, Winkie Direko Building, George du Toit Building, Sasol Library, Francois Retief Building, as well as in the residences. This measure has resulted in massive energy saving.

Energy meters for the Library, Computer Laboratory Building, François Retief Building and Steyn Substation are being planned as the first phase.

Real-time metering will result in every UFS computer user being aware of power consumption on the campus.

New lift motors and control systems that reduce energy consumption have been installed at the Agriculture and the George du Toit Buildings.

In the Computer Laboratory Building the temperature adjusting point for the venues is set at 22 °C and, in the case of new projects, green guidelines are applied.

It is expected that the government and local authorities will bring more pressure to bear on the UFS to save energy. Applications for increased capacity will possibly be linked to energy-saving targets.

This trend will continue until 2014 when additional power stations will be put into operation.

“Our aim is to save 10% on energy consumption,” said Prof. Viljoen.

“Heavy financial penalties will be imposed if a 10% saving is not achieved,” added Mr Calitz.

On average, our energy consumption per day this year is 128,964 kWh as compared to last year’s 119,752 kWh.
