A study published in PLOS One says short breaks help workers have more energy and feel less tired.
The development is based on neurophysiological changes - the brain at some point stops processing stress and information properly, adaptation to constantly influencing factors gradually decreases, symptoms of professional burnout develop.
Change in feelings: depression, gallows humor, feelings of failure, guilt, bitterness, irritability, feeling nitpicky.
Changes in thinking: decreased concentration, rigidity, suspicion, incredulity, victim mentality, callousness.
Changes in health: sleep disturbance, fatigue, decreased immunity.
This is a long protracted process that matures and accumulates over time, taking a person out of working condition for a long time.
If chronic work-related stress lasts more than 3-6 months, it indicates emotional burnout.
