Shift work significantly disrupts the circadian clock, leading to a mismatch in sleep patterns and hormonal rhythms, with only a small percentage of long-term night shift workers adapting fully. This disruption can result in shift work disorder, characterized by insomnia, excessive sleepiness, and increased irritability, while also raising the risk of serious health issues such as various cancers and chronic diseases by 20 to 35%. The implications of working night shifts extend far beyond fatigue, affecting overall well-being and workplace safety.
