Both calculators run independently — change the inputs on either side to compare results.
Shift Work Sleep Calculator
Plan your sleep window around rotating or night shifts by accounting for shift times, commute, and adjustment buffers. Use it when your schedule changes to find the exact bedtime that protects your minimum sleep hours.
Sleep Temperature Optimizer
Recommends an ideal bedroom temperature in °F for better sleep quality based on season, sleepwear, and bedding weight. Use it when setting your thermostat before bed.
Optimal Room Temperature
65 °F
62-66°F, like the example's 63°F, sits squarely in the 60-67°F sleep-science sweet spot that aids the core temperature drop for deeper sleep.
Bands center on the sleep-research optimum of 60-67°F (about 65°F), the range that supports the core-body-temperature drop needed to fall and stay asleep.
