Lowen noted that when people do not want to experience certain emotions, they tighten certain muscles.[19] For example, when someone does not want to cry, they can tighten the jaws, which suppresses tears. Stress and anger tighten the muscles along the spine and thighs, which can manifest itself in pain in those body parts, if the stress was prolonged. According to Lowen, some tensions become chronic: the muscular block always activated, regardless of the circumstances.
