Shift work disorder
Working the night shift? Yup, that’s wrecking your sleep cycle! It should come as no surprise that during the night shift, when your internal clock is saying you should be asleep, you feel excessively tired, fatigued and less alert. That’s also why you might have difficulty falling and staying asleep during the day, when your body’s sleep-wake rhythm demands you be awake. One trick to help? Begin altering your sleep schedule three days in advance of a shift change. On the third day prior to the shift change and each subsequent day, postpone your bedtime and wake time by one to two hours compared to the previous day. By the time you begin the new shift, your circadian sleep-wake rhythm will be reoriented.
