Worry about life, body, health: obstacle for Arahataphala?

Is worry about life, body health, e.g. householding, status-maintaining, obstacles for Arahataphala? Is this in accordance with what the Teacher taught? And why is such an obstacle? Would one believing no former, no next life (deny rebirth), not hold either strong on kaya (Sakkaya), worry about life and health, or falls into ideas of "abounding life will be Nibbana, end of suffering"?
