Nocturnal blood pressure (BP) shows the highest predictive power for cardiovascular events. However, there is a poor reproducibility of personalized dipping patterns in single individuals. We hypothesize that changes in body position during sleep cause variations in hydrostatic pressure,leading to incorrect BP values and dipping classifications.

This narrative review highlights the challenges associated with conventional (cuff-based) BP measurement and potential solutions. This work covers each method of cuff-based BP measurement, as well as cuffless alternatives, but is primarily focused on ambulatory BP monitoring.

- Orthostatic dysregulation can happen when people return to normal gravity after being in microgravity, which is common in space travel; external peripheral skin cooling (PSC) has been proposed as a potential solution to this issue.
- A study called "Coolspin" was conducted with 18 healthy male volunteers, testing PSC while subjected to increased gravitational forces (up to +4g) in a centrifuge, measuring various cardiovascular parameters.
- The results showed that PSC did not significantly improve cardiovascular stability or hemodynamic activity during +Gz, suggesting that the cooling method used may not have been adequate or the subjects' responses to cooling were low, indicating a need for further research.
