Why Do I Get So Hot While I Sleep?

While you could be getting hot simply because of the temperature of your environment, there are numerous other reasons you may be overheating during your sleeping hours. 

Sharing Your Bed

The human body generates heat, which is an essential function as it helps to keep us alive. But sleeping next to someone who is also generating heat can lead to some pretty uncomfortable and sweltering nights.

Sleep Apnea

If you are sweating excessively at night, it could be a sign of Obstructive Sleep Apnea (OSA). If you are experiencing chronic night sweats in conjunction with other symptoms such as snoring, choking, gasping and frequent bathroom visits, it may be time to visit a doctor.

Anxiety can affect sleep in many different ways, often leading to insomnia. Intrusive thoughts and overthinking caused by stress can lead to night sweats, creating an uncomfortable night’s sleep. 

Night Sweats

Night sweats can be caused by a variety of conditions, including bacterial infections, infectious diseases, cancer, anxiety, neurological conditions and OSA. They can also be caused by hormone imbalances, and they certainly affect your temperature at night and your overall quality of sleep. 

Fluctuating Blood Sugar Levels

Fluctuations in blood sugar levels can heavily impact your sleep, and those that have low blood sugar levels during the night often struggle with night sweats.

Illnesses or other Health Complications

Illnesses and other health complications can also have an impact on your temperature during the night, which can affect sleep. 

Cold or Flu

Viral illnesses such as the cold and flu often cause night sweats because of an increased body temperature. This is only temporary and should go away as you recover from the illness. You can also take anti-fever medications to increase your comfort levels during this time.

People with Type 2 diabetes often experience night sweats because of low blood glucose levels caused by insulin intake. If you experience this on a frequent basis, you should consult with your doctor as it could indicate an imbalance of the medication. 


Hyperthyroidism can cause people to sweat across their whole body. This often occurs during the night, which can create an uncomfortable night’s sleep.

Menopause or other Hormonal Changes

Changes in estrogen and progesterone during menopause can cause fluctuations in body temperature at any time of the day or night. This can be particularly disruptive to sleep, but Cognitive Behavioral Therapy for menopausal women may decrease sleep disturbances. 


Certain medications can affect body temperature or perceived body temperature, which can make you feel hot or sweaty during the night.  

Why Is It Important to Stay Cool at Night While Sleeping?

You might not actually feel bothered by your temperature at night, but it’s still an important aspect of getting a good night’s sleep. This is how staying cool at night can positively affect your sleep. 

How Does Staying Cool Affect Sleep?

Studies indicate that sleeping in a warm environment lowers the amount of REM sleep that your body is able to get. Experts advise that the best temperature to sleep in is between 60 – 67 F.

Are There Any Potential Health Risks to Continuously Sleeping Hot?

Sleeping in high temperatures can affect the amount of deep sleep you get during the night as well as lower the amount of time you’re able to stay asleep. Over time, this could cause an accumulation of sleep debt.

10 Tips to Stay Cool While Sleeping

Looking to stay cool for a peaceful night of sleep? Here are our top 10 tips. 

#1. Keep Your Bedroom Dark During the Day

If your curtains are open all day, your room can heat up significantly, leaving you feeling uncomfortably warm at night. If you are going to be out of your bedroom during the day, use blackout curtains to keep the light out and prevent your room from heating up. 

#2. Add a Fan

Fans can increase airflow and cool down your room quite nicely. But if you would like a device that specifically cools down your bed, consider getting a BedJet Climate Comfort System.

#3. Lower Your Thermostat

Lowering your thermostat closer to bedtime can help you to get a higher quality of sleep. The ideal bedtime temperature is between 60 – 67 F. 

#4. Wear Breathable Clothing

Staying comfortable during the night is essential to getting a good night’s sleep, and what you wear to bed can greatly affect your comfort levels. Try wearing breathable clothes like Cozy Earth Loungewear or Brooklinen Loungewear. If you’d prefer to go with the coolest option, then it might be time to try sleeping naked

#5. Sleep Barefoot

While it’s not bad to sleep with your socks on in certain circumstances, it could inhibit circulation and make you overheat. If you already struggle with staying cool during the night, it might be time to hit the sack barefoot. 

#6. Stay Hydrated

Dehydration can dysregulate your body temperature at night, causing you to feel either too hot or too cold. Ensure that you drink enough water during the day.

#7. Avoid Certain Food and Drinks before Bed

The consumption of alcohol, caffeine and spicy food can cause night sweats and disrupt your thermoregulatory system. If you are looking for a drink to consume close to bedtime, it’s best to stick to herbal teas or anti-energy drinks.  

#8. Take a Warm Bath before Bed

Taking a warm bath before bed helps lower your core temperature, which acts as a circadian sleep signal and makes you feel tired. 

#9. Try an Ice Pack or Cold, Wet Towel

Placing an ice pack or a cold, damp cloth against your skin during the night can help to keep you cool. 

#10. Adjust Your Medications (With Your Physician’s Approval)

If you take medications that interfere with your thermoregulatory system, it might be time to speak to your doctor about adjusting your intake. It’s important to note that this should be done under the guidance of a qualified medical professional.
