Hospitals are typically kept at colder temperatures for several reasons. Firstly, cold temperatures help slow down bacterial and viral growth, reducing the risk of infections in critical areas such as operating rooms and ICUs. Additionally, cooler temperatures prevent condensation, which can lead to cross-contamination and provide a breeding ground for microbes. Furthermore, maintaining cool temperatures helps keep hospital staff comfortable, especially those constantly moving or wearing protective gear. It also aids in preserving medications, blood, and tissues, extending their shelf life. While patient comfort is a priority, hospitals aim to balance this with the health benefits of cooler temperatures, providing blankets, socks, and heated spaces when needed.

What You'll Learn
To slow bacteria growth and limit the spread of viruses
Hospitals are kept at colder temperatures to slow bacteria growth and limit the spread of viruses. Warmer air can carry more moisture, leading to condensation when it comes into contact with cooler surfaces. This condensation can pick up bacteria and viruses, and as it moves from surface to surface, it spreads them too. By keeping the hospital cold, condensation is prevented, and with it, the spread of bacteria and viruses.
Cooler temperatures also slow the degradation process of medications, blood, and tissues for transplants and transfusions, ensuring their longevity. This is similar to the practice of refrigeration in the food industry to prevent bacterial growth.
The Centers for Disease Control and Prevention (CDC) recommends keeping operating rooms and clean workrooms cooler at around 68-73°F (20-23°C) to maintain sterility. Hospitals follow these recommendations to keep their facilities safe and efficient.
Additionally, cooler temperatures help hospital staff stay comfortable, especially those constantly moving or wearing protective gear. It is easier to warm patients up with blankets and extra layers than to cool them down in a heated environment.

To prevent condensation and maintain sterility
Hospitals are typically kept at colder temperatures to prevent condensation and maintain sterility. Warmer air can carry more moisture, which can lead to condensation when it comes into contact with cooler surfaces. This condensation can cause a build-up of bacteria and viruses, which can spread to surfaces, open wounds, and operating equipment, increasing the risk of infection.
Cooler temperatures in hospitals help to reduce humidity and control condensation. This is especially important in laboratories, where medical testing equipment must be kept at colder temperatures to function properly and provide accurate results. By maintaining optimal temperature and humidity levels, hospitals can inhibit the growth of harmful bacteria and viruses, reducing the risk of potential infections in critical areas such as operating rooms and ICUs.
Additionally, cold temperatures can slow down the degradation process of medications, blood, and tissues for transplants and transfusions, ensuring their longevity and effectiveness. Cooler hospital rooms can also reduce medical symptoms for some patients, such as those with fevers or burns, providing a soothing and relaxing environment.
While hospitals prioritize patient care and comfort, the cooler temperatures are a deliberate decision to maintain sterility and prevent the spread of infections. This balance between patient comfort and health and safety requirements can be challenging, but hospitals typically provide blankets, socks, and heated spaces to ensure patients remain comfortable and warm.

To improve patient comfort and sleep
Hospitals are kept at cooler temperatures for a variety of reasons, and while this may not always be comfortable for patients, there are ways to improve their comfort and sleep. Firstly, it is important to note that hospitals are kept cold to prevent bacterial and viral growth, as these thrive in warmer environments. Operating rooms are usually the coldest areas to minimise the risk of infection. Cooler temperatures also help hospital staff stay comfortable as they are constantly moving, and it prevents them from sweating, which increases safety and cleanliness.
It is easier to warm up patients than to cool them down, and temperatures of 60-67°F (15-19°C) are ideal for a good night's rest. Hospitals are aware of this and provide the necessary items to ensure patients can relax and heal. It is important to encourage open communication between patients and caregivers so that any adjustments can be made to enhance patient comfort.

To preserve blood, tissues, medications and medical equipment
Hospitals are kept at lower temperatures for several reasons, one of which is to preserve blood, tissues, medications, and medical equipment.
Cool temperatures slow down the degradation process, prolonging the shelf life of medications and other medical supplies. Heat can cause ingredients in medicines to degrade and lose their effectiveness. By regulating temperature and humidity levels, hospitals ensure the efficacy and functionality of blood and medication storage areas.
Additionally, cold temperatures help prevent bacterial and viral growth. Bacteria and viruses thrive in warm environments, so hospitals combat this by maintaining cooler temperatures, similar to how food safety practices in the food industry rely on refrigeration to keep food fresh and bacteria-free.
Cooler temperatures also help reduce humidity and condensation, which can lead to the spread of contamination on sterilized surfaces, open wounds, and operating equipment. This is especially important in laboratory settings, where specific temperature and humidity requirements must be met for certain equipment to function properly and provide accurate results.
Overall, maintaining cooler temperatures in hospitals is a critical aspect of preserving blood, tissues, medications, and medical equipment, ensuring their longevity and safety for patient use.

To keep hospital staff cool and comfortable
Hospitals are kept at cooler temperatures to ensure the comfort of hospital staff. Hospitals are busy places, with staff constantly on the move, often wearing protective gear, and working long shifts. Cooler temperatures ensure that hospital staff do not feel too hot and prevent them from sweating, which could compromise safety and sterility.
Cooler temperatures also help hospital staff stay focused on their work. This is particularly important in intensive care units and operating rooms, which are usually the coldest areas in a hospital. The Centers for Disease Control and Prevention recommends keeping operating rooms and clean workrooms cooler at around 68–73 °F (20–23 °C).
Cooler temperatures also help hospital staff by making it easier to warm patients up and keep them comfortable. Patients with a fever or burn typically feel more comfortable in a cool room. Hospitals keep lots of blankets, socks, and gloves on hand to help patients stay warm.
While hospitals aim to keep staff and patients comfortable, it can be challenging to find a temperature that suits everyone. Some hospitals have individual thermostats in patient rooms, but when two patients share a room, one may be cold while the other is hot. New technology can help control the temperature for an entire hospital, allowing facility management directors to set the right temperature for patients, medical staff, and visitors.
