Yes, sleeping in a cool room can help manage a fever by regulating body temperature and preventing overheating, but the room should be a comfortable temperature, not too cold. The goal is comfort, not to actively force the body's temperature down rapidly, which can be counterproductive.
Keep the Room Cool
Maintaining a comfortable room temperature is crucial when you have a fever. It is essential to keep the room cool, but not too cold, to promote a more comfortable environment for rest and recovery. Use fans or adjust the thermostat to achieve a suitable temperature.

Your bedroom should be like a cave — dark and cool. When you are ready to turn in for the night, switch the lights completely off. It may even help to sleep on dark sheets. The room temperature should be somewhere in the 60s for restful slumber.
Many people like sleeping in a cool room, but don't make it so cold that you wake up shivering in the middle of the night. When you're feeling sick, you might want to consider raising the temperature a little, rather than letting the thermostat drop. Just don't forget to change it back when you're feeling better.
To get rid of a fever fast, use over-the-counter fever reducers like acetaminophen or ibuprofen, stay very hydrated with water and broths, get plenty of rest, and wear light clothing; use lukewarm sponging for comfort but avoid cold baths or alcohol as they can trap heat. See a doctor for severe symptoms like confusion or extreme fatigue.
Avoid taking cold baths or showers. Skin reacts to the cold by constricting its blood vessels, which will trap body heat. The cold may also cause shivering, which can generate more heat. Make sure you have plenty of rest, including bed rest.
As a general rule, your child should not go to school if they have: A fever over 100.4° Fahrenheit (F) or 38° Celsius (C) – Your child can return to school after they've been fever-free for 24 hours without antipyretics. Antipyretics are medicines that treat or prevent fever.
Researchers have found that cold air can inflame the lungs and inhibit circulation, which can be challenging for people with asthma and chronic obstructive pulmonary disease (COPD). 12. Keeping your room too cold can even inhibit your body's ability to fight a cold or flu.

A fever's danger zone generally starts around 104°F (40°C) for adults and can become a medical emergency above 105.8°F (41°C), requiring immediate attention, especially if accompanied by confusion, severe headache, stiff neck, trouble breathing, seizures, or drowsiness; for infants, any fever in a baby under 3 months is a concern, with 100.4°F (38°C) needing a doctor visit.

Myth: Taking a warm or cold bath brings a fever down quickly. Reality: False. People often do everything they can to try to lower a fever, to no avail. You should never take a shower or a warm or cold bath, which would cause a sudden change in temperature that prompts the body to recover its thermal balance.
To break a fever quickly, use over-the-counter fever reducers like acetaminophen or ibuprofen, stay hydrated by drinking water, rest, and use light clothing and cool (not cold) sponging for comfort; however, remember fevers are your body's defense, so focus on comfort and hydration while letting your immune system work, and consult a doctor if the fever is high or persistent.

It might be hard to believe, but it's true — you don't need to treat every fever. “A temperature of 100 to 102 degrees Fahrenheit is considered a low-grade fever,” says Dr. Giacomini. “It might feel uncomfortable, but it's actually a good sign that your body is working hard to fight off the infection.”
