No liquid runs uphill, and if you are using your hands , they are at or above heart level. Swinging helps get the blood circulating to your extremities again.

Why does a swinging pendulum lose energy once it is set into motion?

When a pendulum is released to fall, it changes from Potential energy to Kinetic Energy of a moving object. However, due to friction (ie: air resistance, and the pivot point) and gravity the pendulum's swing will slowly die down. A pendulum gets its kinetic energy from gravity on its fall its equilibrium position which is the lowest point to the ground it can fall, however, even in perfect conditions (a condition with no friction) it can never achieve a swing (amplitude) greater than or equal to its previous swing. Every swing that the pendulum makes, it gradually looses energy or else it would continue to swing for eternity without stopping. Extra: Using special metals that react little to temperature, finding a near mass-less rod to swing the bob (the weight) and placing the pendulum in a vacuum has yielded some very long lasting pendulums. While the pendulum will lose energy with every swing, under good conditions the amount of energy that the pendulum loses can be kept relatively small. Some of the best pendulum clocks can swing well over a million times.
