I have meet people who agree and disagree that you gain a small amount of total health from healing damage. As new player I thought I could play for free, and spent a lot of time on Thule trying to sweat the mobs there, and standing around while I regenerated health. I was standing doing nothing and gained a point of health. So next time I was close to getting a point of health, I died repeatedly by climbing rocks and jumping off, so no skill gain. It took a number of deaths, but I did go up another point in total Health. But it appears to be a tiny amount, so I have tried to calculate it after about a year of play. Here are the relevant skills I have and their contribution to total Health. If a skill that contributes to Health is not listed, I don’t have it yet Skill________________________Health at____________________My skill Agility______________________40__________________________47 Intelligence_________________80__________________________48 Psyche_____________________80__________________________39 Strength___________________20__________________________40 Combat reflexes_____________1600________________________1361 Handgun___________________1600________________________1330 Melee Combat_______________533.3_______________________1046 Rifle_______________________1600________________________1368 Weap.

So for most players the Health Gain for healing would be barely noticeable. So yes it seems some total health is gained from healing damage, but the amount is so small as to not matter to most players.
