It's this yellow bar on your hp that regens your hp automaticly when you receive some damage.

Constitution is a secondary health regeneration system which activates outside of combat. It is represented by a yellow overlay on your health bar. Whenever Constitution activates, your Constitution pool will be drained as your health rapidly refills. If you run out of Constitution, you will no longer rapidly regenerate health outside of combat. To exit combat, you must avoid dealing or taking damage for 2.5 seconds.

Constitution can be restored in various ways:

• Gaining a level
  
• Picking up Vital Essence or Food Rations from a fallen enemy or a Journeyman’s Pack
  
• Looting an Untouched Meal
  
• Dying
  
• Speaking to the Cook in Devil’s Crossing (once per game session)
