Understanding Body Temperature
Your body’s natural hormones, such as melatonin, cortisol, and growth hormone, play a significant role in regulating your core temperature.
Melatonin, for example, is released by your brain in response to darkness and helps to lower your core temperature, which can make you feel drowsy and ready for sleep. Cortisol, on the other hand, is released in response to stress and can raise your core temperature, making it harder to fall asleep.
When you sleep, your core temperature drops, which helps to initiate and maintain sleep. If your room is too warm, it can interfere with this natural process and make it harder for you to fall asleep and stay asleep.
According to the Cleveland Clinic, the ideal temperature for sleep is between 60 and 67 degrees Fahrenheit (15 and 19 degrees Celsius). This temperature range helps to promote the natural drop in your core temperature and can improve the quality of your sleep.

Role of Room Temperature
The temperature of your room plays a crucial role in determining the quality of your sleep. If your room is too hot or too cold, it can disrupt your sleep and leave you feeling tired and groggy in the morning.
The ideal temperature for sleep varies from person to person, but generally, a temperature between 60-67°F (15.6-19.4°C) is recommended for most sleepers. This range is considered to be the sweet spot for promoting restful sleep, as it helps your body to regulate its internal temperature and maintain a comfortable sleeping environment.
If your bedroom temperature is too high, it can cause discomfort and restlessness, making it difficult to fall asleep. On the other hand, if it is too cold, it can cause shivering and discomfort, leading to a poor night’s sleep.
To maintain a comfortable temperature in your bedroom, you can use a thermostat to adjust the temperature as needed. You can also consider insulating your room to prevent heat loss during the night and improving ventilation to allow for proper air circulation.
Sunlight can also affect the temperature of your room. If your room receives a lot of sunlight during the day, it may become too hot, especially during the summer months. You can use blackout curtains or blinds to block out sunlight and keep your room cool.
Impact of Age and Gender
Your age and gender can also play a role in the temperature of your room at night. Hormonal changes, such as those experienced during menopause, can cause hot flashes and night sweats, leading to a feeling of warmth. In contrast, as you age, your body may become less efficient at regulating temperature, causing you to feel colder at night.
According to a study published in the Sleep journal, women tend to experience more sleep disturbances than men, including difficulty falling asleep and staying asleep. Women also tend to have a higher body temperature during the luteal phase of their menstrual cycle, which can make it more difficult to sleep comfortably.
In addition to gender, age also plays a role in how your body responds to temperature changes. As you age, your body’s ability to regulate temperature decreases, making you more susceptible to feeling cold. This can be exacerbated by factors such as poor circulation, which can make it more difficult for your body to distribute heat evenly.
To combat these issues, it’s important to create a sleep environment that is conducive to your individual needs. This may involve adjusting the temperature of your room, using a fan or air conditioner to circulate air, or investing in bedding that is designed to regulate temperature.
Here is a table summarizing the effects of age and gender on sleep and temperature regulation:
| Age | Gender | Effects |
|---|---|---|
| Younger | Male | More efficient temperature regulation |
| Younger | Female | Higher body temperature during luteal phase of menstrual cycle |
| Older | Male | Decreased temperature regulation, more susceptible to feeling cold |
| Older | Female | Hormonal changes can cause hot flashes and night sweats, decreased temperature regulation |
Medical Conditions Affecting Temperature
There are several medical conditions that can affect your body’s temperature regulation and cause you to feel hot or cold at different times of the day. Here are some of the most common conditions:
Hyperthyroidism
Hyperthyroidism is a condition where your thyroid gland produces too much thyroid hormone. This can cause your body’s metabolism to speed up, leading to an increase in body temperature and excessive sweating.
Other symptoms of hyperthyroidism include weight loss, fatigue, and rapid heartbeat. If you suspect you have hyperthyroidism, it’s important to see a doctor for a proper diagnosis and treatment.
Obstructive Sleep Apnea
Obstructive sleep apnea is a sleep disorder where your breathing is interrupted during sleep. This can cause you to wake up frequently during the night, leading to poor sleep quality and daytime fatigue.
It can also cause you to feel hot and sweaty during the night due to the effort your body is making to breathe. Treatment for obstructive sleep apnea may include lifestyle changes, such as losing weight or quitting smoking, or using a continuous positive airway pressure (CPAP) machine.
Infection
Infections can cause your body temperature to rise as your immune system fights off the invading bacteria or virus. Common symptoms of infection include fever, chills, fatigue, and body aches.
If you suspect you have an infection, it’s important to see a doctor for proper diagnosis and treatment, which may include antibiotics or antiviral medication.
Low Blood Sugar
Low blood sugar, or hypoglycemia, can cause you to feel cold and clammy, as well as shaky and lightheaded. This is because your body is not getting enough glucose to fuel its activities.
Low blood sugar can be caused by a variety of factors, including not eating enough, taking too much insulin or other diabetes medication, or exercising more than usual. If you have diabetes, it’s important to monitor your blood sugar levels regularly and seek medical attention if you experience symptoms of low blood sugar.
HIV
HIV can affect your body’s ability to regulate its temperature, leading to fever, chills, and night sweats. Other symptoms of HIV may include fatigue, weight loss, and swollen lymph nodes. If you suspect you have HIV, it’s important to get tested and seek medical treatment as soon as possible.
Lupus
Lupus is an autoimmune disease that can cause a wide range of symptoms, including fever, fatigue, joint pain, and skin rash. It can also affect your body’s temperature regulation, causing you to feel hot or cold at different times of the day. Treatment for lupus may include medication to manage symptoms and reduce inflammation.
Hyperhidrosis
Hyperhidrosis is a condition where you sweat excessively, often without any obvious cause. This can cause you to feel hot and uncomfortable, especially at night. Treatment for hyperhidrosis may include prescription antiperspirants, medication, or surgery to remove sweat glands.
If you are experiencing symptoms of any of these conditions, it’s important to see a doctor for proper diagnosis and treatment. By addressing the underlying medical condition, you can improve your body’s temperature regulation and enjoy a better night’s sleep.
Sleep Stages and Temperature
The temperature of your room can affect your sleep quality and the different stages of sleep you experience throughout the night. During the first stage of sleep, you are in a light sleep and can be easily awakened. If your room is too warm, you may experience increased wakefulness and decreased slow-wave sleep, which is the stage in which you get the most rest.
As you progress into deeper sleep stages, your body temperature drops. In the third stage of sleep, also known as slow-wave sleep, your body is in its deepest sleep. During this stage, your body temperature is at its lowest point, and you may experience shivering or goosebumps if your room is too cold.
In the final stage of sleep, rapid eye movement (REM) sleep, your brain activity increases, and you may experience vivid dreams. During this stage, your body temperature is slightly warmer than during slow-wave sleep, but still lower than when you are awake.
To optimize your sleep quality, it is recommended to keep your room cool, between 60 and 67 degrees Fahrenheit (15.5 to 19.5 degrees Celsius). This temperature range can work in tandem with your body’s natural temperature fluctuations during sleep, signaling to your body that bedtime is approaching.
Table: Sleep Stages and Temperature
| Sleep Stage | Description | Body Temperature |
|---|---|---|
| Stage 1 | Light sleep, easily awakened | N/A |
| Stage 2 | Deeper sleep, body temperature drops | N/A |
| Stage 3 | Deepest sleep, body temperature at its lowest point | Colder |
| REM Sleep | Brain activity increases, vivid dreams, slightly warmer than slow-wave sleep | Warmer |
In summary, the temperature of your room can affect your sleep quality and the different stages of sleep you experience throughout the night. Keeping your room cool within the recommended temperature range can help optimize your sleep quality and promote restorative, slow-wave sleep stages.
External Factors
There are several external factors that can contribute to your room feeling hot at night and cold in the morning. Here are a few possible culprits and what you can do to mitigate their effects:
Room Temperature and Humidity
If your room feels too warm at night, it may be because the temperature is too high. According to a 2012 research review, exposure to heat can interfere with your body’s natural cooling mechanisms, making it harder to fall asleep and stay asleep. Ideally, your bedroom should be between 60 and 67 degrees Fahrenheit for optimal sleep.
Humidity can also play a role in how hot or cold your room feels. High humidity can make the air feel warmer and more oppressive, while low humidity can make it feel cooler and more refreshing. Consider using a humidifier or dehumidifier to maintain a comfortable level of humidity in your bedroom.
Bedding and Blankets
The type of bedding and blankets you use can also affect how hot or cold you feel at night. If your blankets are too heavy or thick, they can trap heat and make you feel overheated. Consider using lighter blankets or sheets made from breathable materials like cotton or bamboo.
