While a proper blood pressure reading requires a sphygmomanometer (blood pressure cuff), there are some indirect ways to estimate blood pressure without equipment. These methods often involve observing symptoms like dizziness or fatigue, which can be associated with high or low blood pressure. However, these are unreliable and should not replace a proper medical evaluation. If you suspect you have blood pressure issues, it is crucial to consult with a healthcare professional for accurate diagnosis and management.
