As the temperatures drop, many of us find ourselves wondering if sleeping in a cold room can make us sick. While it’s common knowledge that extreme cold can be detrimental to our health, the relationship between a chilly bedroom and illness is more complex than you might think. In this article, we’ll delve into the science behind sleeping in a cold room and explore the potential risks and benefits of catching some Z’s in a cooler environment.
The Science of Sleep and Temperature
Before we dive into the potential health effects of sleeping in a cold room, it’s essential to understand how our bodies regulate temperature during sleep. When we sleep, our body temperature naturally drops, and our metabolism slows down. This process is controlled by our hypothalamus, which acts as our internal thermostat.
During the night, our body temperature can drop by as much as 1-2°C (1.8-3.6°F), with the lowest temperature typically occurring during the rapid eye movement (REM) stage of sleep. This natural temperature drop is essential for our body to conserve energy and repair itself.
How Cold is Too Cold?
While a cooler bedroom can be beneficial for sleep, there is a limit to how cold is too cold. The ideal bedroom temperature for sleep is between 16-18°C (60-64°F), according to the National Sleep Foundation. Sleeping in a room that’s too cold can disrupt our natural sleep patterns and make us feel uncomfortable.
In fact, a study published in the journal Sleep found that a bedroom temperature below 12°C (54°F) can lead to poor sleep quality and reduced sleep duration. On the other hand, a bedroom temperature above 24°C (75°F) can also disrupt sleep and lead to insomnia.
The Potential Risks of Sleeping in a Cold Room
While sleeping in a cold room may not directly cause illness, it can increase our susceptibility to certain health problems. Here are some potential risks to consider:
Respiratory Issues
Cold air can dry out our respiratory tract, making us more prone to respiratory issues like bronchitis, asthma, and chronic obstructive pulmonary disease (COPD). When our airways are dry, they become more inflamed, which can exacerbate existing respiratory conditions.
Immune System Suppression
Prolonged exposure to cold temperatures can weaken our immune system, making us more vulnerable to illness. When our body is cold, it diverts blood flow from our extremities to our core, which can reduce the circulation of white blood cells and make us more susceptible to infection.
Raynaud’s Disease and Poor Circulation
Sleeping in a cold room can also exacerbate conditions like Raynaud’s disease, which affects blood flow to the fingers and toes. When our body is cold, the blood vessels constrict, reducing blood flow to our extremities. This can lead to numbness, tingling, and pain in our fingers and toes.
Muscle and Joint Pain
Cold temperatures can also cause muscle and joint pain, particularly for people with conditions like arthritis. When our muscles are cold, they become stiffer, which can lead to pain and discomfort.
The Potential Benefits of Sleeping in a Cold Room
While there are potential risks associated with sleeping in a cold room, there are also some benefits to consider:
Improved Sleep Quality
Sleeping in a cold room can improve sleep quality by increasing the production of melatonin, the hormone responsible for regulating our sleep-wake cycle. A study published in the journal Sleep found that a bedroom temperature of 16°C (60°F) can improve sleep quality and reduce sleep fragmentation.
Increased Brown Fat
Exposure to cold temperatures can also increase the production of brown fat, a type of fat that’s highly metabolically active. Brown fat can help us lose weight and improve our insulin sensitivity.
Reduced Inflammation
Cold temperatures can also reduce inflammation, which is associated with various chronic diseases like heart disease, diabetes, and cancer. A study published in the journal Nature Communications found that cold exposure can reduce inflammation by activating certain cellular pathways.
Who’s at Risk?
While anyone can be affected by sleeping in a cold room, certain individuals are more susceptible to the potential risks:
The Elderly
Older adults are more prone to hypothermia, which can be life-threatening. As we age, our bodies become less efficient at regulating temperature, making us more vulnerable to cold temperatures.
Young Children
Young children are also at risk of hypothermia, particularly if they’re not dressed warmly enough for bed. Children under the age of 6 months are especially vulnerable, as they have a higher surface-to-volume ratio and lose heat more quickly.
People with Chronic Health Conditions
Individuals with chronic health conditions like diabetes, heart disease, and respiratory disease are more susceptible to the potential risks of sleeping in a cold room. These conditions can impair our body’s ability to regulate temperature, making us more vulnerable to cold temperatures.
Conclusion
Sleeping in a cold room can have both positive and negative effects on our health. While it can improve sleep quality and increase the production of brown fat, it can also increase our susceptibility to respiratory issues, immune system suppression, and muscle and joint pain.
To stay safe and healthy, it’s essential to find a comfortable bedroom temperature that works for you. The ideal temperature range is between 16-18°C (60-64°F), but this can vary depending on individual preferences and health conditions.
By understanding the science behind sleep and temperature, we can make informed decisions about our bedroom environment and stay healthy and comfortable throughout the night.

Can sleeping in a cold room really make you sick?
Sleeping in a cold room can potentially weaken your immune system, making you more susceptible to illness. When your body is exposed to cold temperatures, it diverts blood flow from your extremities to your core to maintain its internal temperature. This can lead to a decrease in the production of white blood cells, which are vital for fighting off infections. Additionally, a cold environment can cause your body to release stress hormones, such as cortisol, which can further suppress your immune system.
However, it’s essential to note that sleeping in a cold room alone is unlikely to cause illness. Other factors, such as poor air quality, inadequate sleep, and pre-existing health conditions, can contribute to the development of sickness. To minimize the risks, ensure your bedroom is well-ventilated, and maintain a comfortable sleeping temperature between 60°F and 67°F (15.5°C and 19.4°C).
