Physical health is defined as the condition of your body, taking into consideration everything from the absence of disease to fitness level.
Physical health is critical for overall well-being, and can be affected by:
- Lifestyle: diet, level of physical activity, and behaviour (for instance, smoking);
- Human biology: a person’s genetics and physiology may make it easier or harder to achieve good physical health;
- Environment: our surroundings and exposure to factors such as sunlight or toxic substances;
- Healthcare service: good healthcare can help prevent illness, as well as detect and treat illness.
