Human Performance
It is not only a matter of being physically tired, but can also affect decision-
making, responsiveness and communication, which are necessary for safety.
Chronic exhaustion is far more serious than acute exhaustion, as the cause is

Chronic exhaustion requires a thorough and customized treatment plan. It is
about finding the balance between medical treatment, lifestyle changes and
psychological support.
