The protagonist can sometimes receive temporary statuses that influence some of his/her parameters. Statuses are divided into positive (e.g. picture 1) and negative (like in picture 2). Positive statues include "Well Fed" which is triggered after consuming a large quanitity of food and drink in a short timespan. This status provides temporary regeneration of Health points and enhances the speed of Stamina points restoration.
Negative statuses are more common, unfortunately. The most popular one is Exhausted which is caused by depleteing the Stamina bar. It prevents you from running and decreases the strength and speed of melee attacks. Apart from that, you can also suffer negative statuses connected to, for example, high radiation. It's a good idea to frequently launch TranScribe and check the Status bookmark. You can then search the inventory for items that could help you get rid of negative statues or wait until they are automatically removed.
