Can We Protect Our Hearts by Sweating Out Excess Sodium?

Excess dietary sodium increases blood pressure during exercise, contributing to an increased risk of future cardiovascular disease. Nine in 10 adults exceed the recommended sodium intake. Dermal excretion through sweating represents a complementary pathway that can excrete sodium independently of the kidneys. This review synthesizes evidence that sweat-inducing interventions could facilitate meaningful sodium losses, representing a novel strategy to attenuate cardiovascular strain.
