Compare calculators
Both calculators run independently — change the inputs on either side to compare results.
Sleep Efficiency Calculator
Calculate your sleep efficiency percentage — the ratio of actual sleep to time spent in bed — adjusted for night wakings and how long it takes you to fall asleep. Use it to assess whether poor sleep quality, not just duration, is the issue.
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.
