Your day at work really starts the night before. If you sleep well, then you'll be well-rested for the busy day ahead. If you sleep poorly, you'll feel the repercussions for the rest of the day. We've all been there.
Of course there are many things to do to help with getting a good night's rest — no gadgets before bed, no caffeine in the afternoon, a serene sleeping space, a cozy bed — there is something to be said for temperature too. According to sleep.org the ideal sleeping temperature is between 60 and 67 degrees Fahrenheit for optimal sleep.
When you're trying to fall asleep, or starting to fall asleep, your body temperature decreases and the 60-67 degree window can help make that happen. If your room is much warmer or much colder than the temperatures proposed above, it's possible that you'll be in for a restless night.
Of course, these are optimal numbers and not requirements. But if you're feeling like your daytime hours aren't living up to their potential, maybe it's your thermostat that needs a little finagling. Otherwise you might find yourself nodding out in the next day's climate-controlled meeting. Like we said, a great day's work really begins the night before.
