How does exercise impact mental health?
Sources:
Exercise has multiple effects on mental health, as discussed in various episodes of the . Some key points mentioned by include:
- Exercise can increase blood flow to the brain and positively impact brain function 1.
- Resistance training releases hormones from bones, like osteocalcin, which support the health of existing neurons 1.
- The improvement in blood flow and cardiovascular fitness from exercise is suspected to indirectly enhance neurogenesis in the hippocampal dentate gyrus, a key area for memory 2.
- Acute effects of exercise include enhanced mood, improved prefrontal function, increased reaction time, and sustained attention, with benefits that can last up to 2 hours post-exercise 3.
- Regular exercise, particularly aerobic, causes the release of neurochemicals like dopamine, serotonin, noradrenaline, and brain-derived neurotrophic factor (Bdnf), which promotes the growth of new brain cells in the hippocampus and can help delay the onset of dementia 4.
- The power of mindset can influence the physiological outcomes of exercise, suggesting that believing in the benefits of exercise can lead to actual health improvements 5.
Overall, exercise contributes substantially to both brain health and mental health by promoting brain function, enhancing cognitive abilities, and fostering emotional well-being.
