Energy is a Core Character Stat in DayZ. High Energy and Water levels allow you to regenerate blood faster and avoid starvation. It's also one of the 4 stats that contribute to the survivor's Immune system strength.

Overview[ | ]

Energy is vital for the long-term maintenance of a character. Maintaining a healthy energy intake keeps blood regeneration rates high. A player starts with 600 energy and may hold a maximum of 5000. There are a total of 5 different HUD icons that indicate how much energy your character currently has.

* The amount of damage varies, because the health is always regenerating simultaneously with it. So the effective damage rate depends on the survivor's blood stat's level.

Losing Energy[ | ]

As in real life, energy is constantly required due to a character's metabolic system. Therefore, similar to Water, it is one of the few character stats that will not remain constant.

Player Actions[ | ]

Lost through varying degrees of exertion, a Survivor's energy levels are affected by their activeness, as seen below.

Player Action Energy Loss*
per second
Energy Loss*
per minute
Idle 0.01 - 0.02 0.60 - 1.20
Walking 0.10 - 0.20 6.00 - 12.00
Jogging 0.30 - 0.60 18.00 - 36.00
Sprinting 0.60 - 1.20 36.00 - 72.00

* The loss rate depends on the current energy level of the Survivor. At 100% energy level, loss is the highest, and at >0%, the lowest. Meaning that you expend twice as much calories when you're full, compared to being just above zero energy.

Effects[ | ]

Starvation[ | ]

Starvation occurs as a result of a low energy level. At less than 300 energy, the Health stat start sdropping. This continues until the character dies of starvation or replenishes their energy above this threshold.

Blood regeneration[ | ]

 Main Article: Blood

A Survivor's energy level affects how quickly they can regenerate lost blood. The water and energy levels act as multipliers to a final blood recovery rate as seen below.

Blood Regen*

0.075 4.5 300 - 599 200 - 399

0.150 9 600+ 200-399
0.300 18 600+ 600+

* Values are approximate and depend on several factors.

Recovery[ | ]

The survivor can replenish their Energy by eating food and drinking soda cans.
