What is a common contraindication for massage in clients with hypertension?

Clients with hypertension often experience elevated blood pressure levels, which can pose risks during massage. Avoiding techniques that increase blood flow too rapidly is important because such increases can potentially lead to a spike in blood pressure, putting the client at risk for complications. Techniques that promote relaxation and those that are gentle can help manage blood pressure effectively.

In contrast, the other options do not appropriately address the safety concerns associated with clients who have hypertension. Requiring clients to sit upright may not be relevant or necessary for all individuals with hypertension. Moderate pressure being always safe doesn't account for the variability in individual responses to massage, as different clients may react differently to pressure levels. Lastly, suggesting that hot stone treatments are required does not consider the individual's specific needs or health conditions, and the use of heat can sometimes exacerbate hypertension in certain clients. Therefore, the emphasis on avoiding rapid increases in blood flow is essential for ensuring safety in this population.
