These days I've been waking up with a bit of energy, and bathe for just two minutes in a tub of hot or warm water. Five minutes later, exhaustion sets in and gets worse and worse, til I can barely hold a pencil. The equation is roughly two minutes in the bathtub, three or four hours lying down, too tired to move or think. Part of me wonders if I'm just going through a very fatigued phase and am connecting the bath to exhaustion that would kick in soon after getting up anyway. Has anyone else found that immersion in warm or hot water brings on the depths of fatigue?
