INTRODUCTION "Cardiovascular drift" (CV drift) is a phenomenon whereby some CV responses begin a continuous time-dependent change, or "drift," after 10 min of prolonged moderate-intensity exercise (e.g., 50-75% Vo 2 max) in a neutral or warm environment ().As displayed in Figure 1A, it is characterized by a progressive decline in stroke volume (SV) and pulmonary and systemic . 3.1.1.2 Cardiovascular system. 7582. . Cardiovascular physiologists suggest that cardiac drift is connected to an increase in core temperature and body water losses. Hydration has many important functions for health, including the regulation of body temperature and blood pressure, cleaning the body and removing it of stored toxins, supporting immune function, aiding digestion and ensuring transportation of oxygen and nutrients around the body. A combination of an increased heart rate and blood viscosity puts greater strain on the heart, resulting in our heart working harder at a given intensity, potentially resulting in early fatigue. Secondly, feeling thirsty is an indicator that you are already dehydrated. 2006 Jul;77(7):687-94.
