Hospitals are kept at colder temperatures for a multitude of reasons. Firstly, cold temperatures slow down bacterial growth and limit the spread of viruses and diseases, creating a sterile environment. Secondly, cooler temperatures help hospital staff stay comfortable and focused as they work, preventing heat exhaustion and excessive sweating. Thirdly, cold temperatures help preserve blood, medications, tissues, and vaccines. Additionally, cool temperatures ensure medical equipment stays functional and accurate, especially in labs and MRI rooms. Lastly, hospitals maintain cooler temperatures to help patients with fevers and burns find relief and prevent sweating and excessive bleeding after surgery.

What You'll Learn
Prevent bacterial growth
Hospitals are kept cold to prevent bacterial growth. Bacteria thrive in warm and humid environments, so hospitals use cold temperatures to slow down bacterial and viral growth, thereby reducing the risk of infection. This is similar to how refrigeration is used in the food industry to prevent harmful bacteria from growing on food items.
Cooler temperatures also help to prevent condensation from forming on walls, surfaces, and medical equipment. Condensation and humidity can lead to the growth of bacteria and fungi. By keeping the hospital's air conditioning running, warm, damp air is cycled out, helping to keep the hospital clean and sterile.
In addition to preventing bacterial growth, cold temperatures help to offset the heat generated by medical equipment, ensuring they stay functional and do not malfunction. Certain rooms, such as operating rooms, MRI rooms, and labs, are kept cooler to prevent the equipment from overheating.
While hospitals prioritize patient care and safety through temperature regulation, they also provide measures to ensure patient comfort. Hospitals typically offer warm blankets, heated IV fluids, socks, gloves, and heating pads to patients who may feel too cold.

Keep staff from overheating
Hospitals are kept cold to prevent staff from overheating. Doctors, nurses, and other hospital staff are constantly moving between rooms and buildings, wearing scrubs, masks, and personal protective equipment (PPE). This can cause them to overheat and sweat, so the hospital's cold temperatures ensure they stay comfortable and clean. The cold also helps staff stay alert and composed, especially in operating rooms, where bright lights and machinery generate additional heat.
Cooler temperatures help both the hospital and equipment operate more efficiently. In warmer environments, condensation can form on walls and medical equipment, leading to bacterial and fungal growth. By keeping the hospital cold, the air conditioning helps cycle out warm, damp air, preventing condensation and the growth of bacteria and mould.
While patient comfort is a priority, hospitals must balance this with health and safety concerns. Blankets, heating pads, and controlled warm air can be provided to ensure patients remain comfortable and do not get too cold.
Additionally, cooler temperatures are beneficial for certain patients, such as those recovering from burns or suffering from fevers, as the cool air can provide relief.

Avoid humidity
Hospitals are kept cold to avoid humidity and condensation. Humidity and condensation can cause bacterial and fungal growth, which increases the risk of infection. By keeping the hospital cold, condensation is prevented from forming on walls, surfaces, and medical equipment.
Cool air holds less moisture than warm air, which helps reduce humidity and condensation in hospitals. This is especially important in lab environments, where equipment must be kept at colder temperatures to function properly and provide accurate results.
The Centers for Disease Control and Prevention (CDC) recommends that patient rooms in healthcare facilities be kept around 24°C (75°F). However, this temperature may vary depending on the specific needs of the patient. For example, warmer temperatures are usually preferred in hospital patient rooms and delivery rooms to provide greater comfort for patients.
To maintain patient comfort in colder hospital rooms, healthcare facilities provide blankets, socks, heating pads, and controlled warm air. These measures ensure that patients remain comfortable and warm during their stay.

Ensure machines stay functional
Hospitals are typically kept cold to ensure machines stay functional. Medical equipment, such as MRI machines, generates a lot of heat when used. By maintaining a cold temperature in the hospital, the heat generated by the equipment is offset, preventing malfunctions and keeping them in good condition.
Cooler temperatures are also beneficial for the functionality of other hospital machinery and technology. For instance, diagnostic imaging equipment used in catheterization laboratories and cameras employed in endoscopy units require a colder environment to operate effectively.
Furthermore, cold temperatures in hospitals help maintain the efficacy and functionality of blood and medication storage areas. Many medications and vaccines are stored in cool temperatures to prevent the ingredients from degrading and losing their effectiveness.
Additionally, hospitals with older infrastructure may face challenges in temperature control due to outdated heating, cooling, and ventilation systems. However, new technology, such as remote temperature monitoring systems, allows facility managers to set the right temperatures for patients, staff, and visitors throughout the hospital.
While patient comfort is a priority, hospitals strive to balance this with the need to maintain optimal temperatures for the proper functioning of medical equipment and the overall safety of patients and staff.

Help patients with fevers and burns
Hospitals are kept cool to help patients with fevers and burns. Cooler temperatures help patients with fevers and burns find relief. Patients with these conditions often feel hot, so hospitals keep their rooms cool to soothe and relax them. Cool air also prevents patients from sweating and getting wounds dirty, which lowers the risk of infection.
Cool temperatures also reduce blood flow by constricting blood vessels, which helps surgery patients heal. Hospitals are also kept cool to prevent bacteria growth, as bacteria thrive in warm temperatures. The cold temperature also helps to keep hospital staff alert and comfortable, especially those in operating rooms, as they are constantly moving and may overheat.
While hospitals are kept cool, they are also well-equipped with blankets, socks, gloves, heating pads, and controlled warm air to ensure that patients remain comfortable and do not get too cold. Warmer temperatures are recommended in areas that require greater degrees of patient comfort, such as patient rooms and delivery rooms.
