Nutrition: Not only does eating affect our bodies, but our minds as well. The central nervous system, the brain and the spinal cord use the nutrition we ingest to operate properly. The brain uses about 20% of our blood sugar and neurotransmitters in the brain are made up from dietary substances. Exercise: The most important type of exercise that people need for health and well-being is regular aerobic exercise – or high intensity, long-duration activities that increase both heart rate and oxygen intake. Cardiovascular and respiratory fitness are particularly valuable to psychological well-being because they increase the amount of oxygen reaching the brain, enhancing thinking and neurological functioning. As well, many studies have tied regular exercise to improvements in self-concept, self-esteem and well-being, as well as a reduction in depression. Employee fitness programs have resulted in reduced absenteeism, increased job satisfaction and lower healthcare costs. Related Links Health Psychology |
