How time of day affects pain and exercise response
Part of Brain & nervous system clinical trials.
This study looks at how your body feels pain at different times of day and whether exercise changes that feeling. You would do simple pain tests and light exercise sessions, and the results may help understand how our internal clock affects pain.
