Hotel staff try their best to ensure every guest is comfortable. This includes everything from food to furniture. Unfortunately, one area that’s tough to please everyone is room temperature—some people like cold and some people like warm. That’s why most hotels have thermostats in the rooms, allowing guests to crank the heat up or down to their liking.

Depending on the hotel, you may or may not have control over the thermostat. Some hotels disable the functions and ask that you contact front desk to request a change in temperature. If you’d rather do it yourself, though, you can try a well-known hack for bypassing thermostat administrative locks:

• Hold down the “display” button and press “off”;
• Continue holding “display”, but release “off” before pressing the “up” arrow;
• Release all buttons, then try to change the temperature again.

Not every thermostat uses the aforesaid buttons, so you may find this trick only partially effective. Regardless, your best bet is usually just to request a little extra warm or cold air instead of tinkering.

Colder Rooms Optimal for Sleep

If you can tweak the thermostat, consider dropping the temperature for nighttime. As your body prepares for sleep, the temperature it regulates lowers a little bit. In warm environments, it has a harder time doing this, so for most people, cool temperatures induce a better sleep—particularly during the rapid eye movement (REM) stage.

While people’s sleeping preferences vary, the best temperature for sleep is between 65 and 72 degrees Fahrenheit. The more athletic you are, the more likely you will find yourself near the bottom of the range.

However, if the hotel room does not allow for temperatures to fall so low, then you’ll need to strip back the blankets or rethink your choice in pajama. You can always open a window to create a breeze for keeping your body temperature lower, too.
