Fallout 4 Healing tip

To heal yourself in Fallout, carry plenty of Stimpacks, consume food, and damage-reducing chems. Often, you can gain meat by killing wild animals in the open areas. However, these creatures have the downside of radiation. Rads or radiation lowers your overall max health, shrinking the possible total and weakening you.  Rad Away or a doctor in Diamond City can remove this, but it’s costly and difficult during the story quest.

Purified water, however, provides a decent amount of health without radiation.  These can be crafted at settlements with Water Purifies, giving you a flood of consumable healing without the Rads. Moreover, keep stimpaks on you for combat situations where you need a burst heal. Consider taking the Medic perk in the intelligence tree for increased healing.
