Reduce or pause when recovery worsens, and stop immediately for chest symptoms, faintness, confusion, uncontrolled breathing, loss of coordination or other distress.<\/p>\n<p>A weekly number copied from another user hides the variables that create the actual cold load. Two sessions at a moderate, measured condition are not equivalent to two longer sessions in colder water, and a person who tolerated a session once has not proven that a daily schedule is appropriate.
