With that in mind, experienced shiftworkers recommend that you…
Advice #1 - You will need to approach sleep differently. Before shiftwork, chances are sleep was most likely something you just did at night. However, as a shiftworker you will be introduced to the challenges of trying to sleep during the day and possibly also to the challenge of having a rotating bedtime.
The beginning of Daylight Savings Time has left many of us feeling a bit fatigued. The 6:30 AM alarm instead feels like a 5:30 AM alarm, and even after a few days, lingering fatigue still seems to exist.
Why is it so difficult to adjust to the time change?
Our internal 24-hour clock – known as our circadian rhythm – doesn’t adjust to daylight savings time – even in the weeks following the time change.1 While the 1-hour time change seems minor, the repercussions of this change are dramatic.
Various studies have found that the beginning of daylight savings time is associated with:
- Increased risk of heart attack 2
- Increased rate of traffic accidents 3
- Greater risk of workplace injuries 4
- Reduced workplace productivity 5
The beginning of daylight savings time reminds us that our circadian rhythms are heavily dependent on our sleep and wakefulness schedules to regulate our alertness, immune response, activity levels, and hormone secretion patterns – along with many other functions.
Imagine if you had to make drastic changes to your sleep schedule every week. This is the reality of millions of shift workers, athletes, and traveling professionals – many of whom are left with feelings of chronic fatigue due these schedule shifts.
Erratic sleep schedules not only result in fatigue – but can lead to metabolic disturbances and other major health problems. While travel sometimes necessitates dramatic, abrupt changes in our circadian rhythm, shift work doesn’t.
Twenty-four hour operations can implement schedules that better complement circadian physiology – based on the rotational direction of schedules, speed of rotation, and pattern of rotation. To learn more about this – download our FREE white paper on biocompatible shift scheduling.
