As the winter months approach, many of us crank up the thermostat to stay cozy and warm in our homes. But what happens when we’re not so lucky? Perhaps you’re a college student stuck in a dorm with a faulty heating system, or a homeowner dealing with a broken furnace on a frigid night. Whatever the reason, sleeping in a cold room can be uncomfortable, to say the least. But can it actually make you sick?
The Science Behind Cold Sleep
Before we dive into the potential health risks, let’s explore how our bodies respond to cold temperatures during sleep. When we sleep, our body’s natural thermoregulation processes are slightly altered. Our core body temperature drops, and our circulation slows down. This is a normal and necessary process, as it helps us conserve energy and recover from the day’s activities.
However, when the room temperature is too low, our body has to work harder to maintain its internal temperature. This can lead to a range of physiological responses, including:
- Increased heart rate: As your body tries to generate heat, your heart beats faster to pump more blood to your extremities.
- Constricted blood vessels: To conserve heat, your blood vessels constrict, reducing blood flow to your skin and extremities.
- Increased respiration: You may breathe more rapidly to take in oxygen, which helps your body generate energy and heat.
These responses can be stressful on the body, especially for extended periods. Now, let’s explore the potential health risks of sleeping in a cold room.
The Risks Of Sleeping In A Cold Room
While sleeping in a cold room might not be the most comfortable experience, it can also lead to several health issues, especially for vulnerable individuals.
Respiratory Issues
Cold air can exacerbate respiratory conditions like asthma, bronchitis, and chronic obstructive pulmonary disease (COPD). When you breathe in cold air, your airways constrict, making it harder to breathe. This can trigger or worsen respiratory symptoms, such as:
- Coughing: As your body tries to clear out mucus and irritants from your airways.
- Wheezing: As your airways constrict, making it harder to breathe.
- Shortness of breath: As your lungs struggle to take in enough oxygen.
Cardiovascular Concerns
Sleeping in a cold room can also put extra strain on your cardiovascular system. The increased heart rate and blood pressure can lead to:
- Cardiac arrhythmias: Irregular heartbeats, which can be a concern for people with pre-existing heart conditions.
- Hypertension: Elevated blood pressure, which can increase the risk of heart disease, stroke, and kidney disease.
- Raynaud’s phenomenon: A condition where the blood vessels constrict excessively in response to cold temperatures, leading to discolored fingers and toes.
Immune System Suppression
Chronic exposure to cold temperatures can weaken your immune system, making you more susceptible to illnesses. This is because:
- Cold stress: Activates the release of stress hormones, like cortisol, which can suppress the immune system.
- Inflammation: Cold temperatures can cause inflammation in the body, which can further impair immune function.
Other Health Risks
Sleeping in a cold room can also lead to:
- Muscle aches and pains: As your muscles contract to conserve heat, leading to stiffness and discomfort.
- Fatigue: As your body expends energy to stay warm, leaving you feeling tired and sluggish.
- Mood disturbances: Cold temperatures can affect your mood, leading to irritability, anxiety, and depression.
Who’s Most At Risk?
While anyone can experience health issues from sleeping in a cold room, some individuals are more vulnerable than others. These include:
- The elderly: As we age, our bodies become less efficient at regulating temperature, making us more susceptible to cold-related illnesses.
- Young children: Children’s bodies are still developing, and they may have a harder time regulating their body temperature.
- People with pre-existing medical conditions: Those with respiratory, cardiovascular, or immune system disorders may be more sensitive to the effects of cold temperatures.
- Pregnant women: Pregnant women may be more susceptible to cold-related health issues due to changes in their circulation and immune system.
Tips For Staying Healthy In A Cold Room
While it’s not always possible to control the temperature of your sleeping environment, there are steps you can take to minimize the risks:
- Dress warmly: Wear warm socks, gloves, and layers to bed to conserve body heat.
- Use blankets and bedding: Pile on the blankets and use a warm comforter to trap warm air close to your body.
- Invest in a warm sleeping bag: Look for a sleeping bag with a good insulation rating to keep you warm throughout the night.
- Stay active: Engage in gentle exercises, like stretching or yoga, to get your blood flowing before bed.
- Use a humidifier: Dry air can make your respiratory system more susceptible to cold temperatures. A humidifier can help maintain a healthy moisture level in the air.
Conclusion
Sleeping in a cold room can be uncomfortable, and it may even pose health risks, especially for vulnerable individuals. While it’s not always possible to control the temperature of our sleeping environment, taking steps to stay warm and cozy can go a long way in minimizing the risks. By understanding how our bodies respond to cold temperatures and taking proactive steps to stay healthy, we can sleep better, even in the chilliest of rooms.

| Above 60°F (15°C) | Comfortable sleeping temperature, normal physiological responses |
Note: The temperature ranges mentioned above are approximate and can vary depending on individual factors, such as age, health, and physical activity.
Can Sleeping In A Cold Room Make Me Sick?
Sleeping in a cold room can make you sick, but it’s not the cold room itself that’s the problem. Rather, it’s the impact that the cold temperature has on your body and your immune system. When you’re sleeping, your body’s natural defenses are lowered, making you more susceptible to illness. Cold temperatures can also cause your blood vessels to constrict, which can reduce blood flow to your nose, throat, and lungs, making you more prone to respiratory infections.
Additionally, sleeping in a cold room can also disrupt your body’s natural sleep patterns. When you’re cold, you’re more likely to wake up during the night, which can disrupt your sleep cycle and make you feel tired and groggy in the morning. This can weaken your immune system, making you more susceptible to illness. So, while sleeping in a cold room itself won’t make you sick, it can increase your risk of getting sick by weakening your immune system and disrupting your sleep.
What Is The Optimal Sleeping Temperature?
The optimal sleeping temperature varies from person to person, but the general consensus is that a cooler room is better for sleep. The National Sleep Foundation recommends keeping your bedroom at a temperature between 60°F and 67°F (15.5°C and 19.4°C) for optimal sleep. A cooler room can help you fall asleep faster and improve the quality of your sleep. A temperature range of 62°F to 65°F (16.7°C and 18.3°C) is often cited as the ideal sleeping temperature, as it allows for a comfortable sleeping environment and can help improve the quality of your sleep.
However, it’s important to note that the optimal sleeping temperature can vary from person to person.
