The 'enormous sacrifice' of shift work can lead to significantly earlier deaths, a senior exec at wearable firm Whoop says

• People in professions where they have to work night shifts are more likely to develop health issues.
• That's according to Whoop's vice president of performance science Kristen Holmes. 
• Holmes explained that night shifts disrupt a person's circadian rhythm and can cause poor mental health.

People who work night shifts may experience disruption to their quality of life and are also at risk of dying as much as 15 years sooner than those who have a more natural work pattern, according to a senior executive at fitness tracker company Whoop.
