#CALIFORNIA SWING SHIFT SCHEDULE TRIAL#
While working that shift, we did a 12 month trial of the 12 hour rotation. I worked another modified schedule that I liked best, which was a combination of both 8 hour and 12 hour shifts. The 8 hour rotation is usually referred to as 'Southern Swing', and it is the hardest of them all.

As “increased exhaustion and fatigue levels” mount, a shift worker’s physical activity levels are bound to decline, they suggested, further upsetting their metabolism. The researchers also point out that shift work is wearing, and that hardly bodes well for a worker’s exercise schedule. We are offering full-time seasonal positions, on work schedules that vary based on location and may include day, mid-day, and swing shifts. And the study may explain why, despite evidence suggesting that night workers eat no more than those on a “normal” sleep-wake schedule, they more often struggle with obesity. Contact Representative (Customer Service Representative) Internal Revenue Service 4.0. Even if the reversal of night and day activities is occasional, burning 50 to 60 calories a day fewer (without adjusting one’s diet accordingly) every once in awhile is a formula for weight gain. The study lacked a control group, and it lasted only six days, which hardly allows researchers to predict how a worker will adapt to a schedule that consistently upends sleep-wake cycles or to one that does so inconsistently.īut it does suggest that even a brief “circadian misalignment” puts the metabolism into a lower gear. And the “thermic effect” of a late-night dinner - the revving that signals the body has taken on a new infusion of fuel - was significantly more muted than their baseline response to an end-of-day dinner. Despite reduced levels of the “satiety hormone” leptin on days 2 and 3, subjects reported lower levels of hunger.
The lower energy expenditure came both during daytime sleep and during night-time wakefulness: their sleep was more fragmented and their energy expenditure at night, when they were awake but their bodies were accustomed to sleeping, remained suppressed.Īs their upside-down schedules entered days 2 and 3, their bodies became more efficient at using fat, but less efficient at using carbohydrates and protein.
