After a long day, you’re ready to fall into your bed. You let out a huge breath of relief and then thought, “What a long and tiring day.” I’m just ready to fall asleep.’

After falling asleep in bed, you begin to feel the twists and turns begin. Then, when you’re still asleep, you take off your blanket and move towards the opposite side. It helps for a while. Things begin to get warmer and warmer, and you start to get up more. Then you get covered in sweat, uncomfortable, and sticky.


The question arises why do i get hot when i sleep? Let’s try to discuss it.

What Is the Real Cause of Feeling hot when i Sleep?

Being hot at night is common and usually has an easy fix. But some have night sweats. Night sweats are excessive sweating that occurs in the body throughout the night. These hot flashes occur at night and aren’t related to the temperature of the room you are sleeping in.

The Reason for Your Insufficient Sleep

Although there’s nothing you can do to change the natural events that happen to your body, some changes to your lifestyle can help you control your body’s temperature. Your sleeping environment can significantly influence your body temperature, which can cause your body to wake up when you’re too hot or cold. Here are some points to think about if you’re constantly awake with an elevated body temperature during the night:

1. Medication

A wide array of drugs could increase your body temperature or even disrupt your body’s ability to regulate the temperature.

Commonly used medicines that can affect thermoregulation include:

  • Anticholinergics
  • Beta-lactam antibiotics
  • Carbamazepine
  • Diabetes medication
  • DiureticsTrusted Source
  • Medications for hormone therapy
  • Methyldopa
  • Painkillers such as Acetaminophen (Tylenol) and aspirin
  • Phenytoin
  • Procainamide
  • Psychotropics
  • Quinidine
  • SSRI (or tricyclic) antidepressants
  • Steroids like cortisone and prednisone
  • Drugs

2. You Play Sports or Work Often

There are many benefits of living an active and athletic lifestyle: you’ll have a healthy, strong body and plenty of energy, and in general, you may feel in a great mood. One downside? You’re likely to become hot at night because your body works hard to repair muscles while you’re sleeping.

  1. This is especially the case if you recently increased your exercise routine. To help support this intensity, the thyroid gland produces additional hormones that could temporarily alter the body’s ability to regulate temperatures while you’re sleeping.
  2. Are you under-fueling or not getting the proper nutrients? This can result in lower blood sugar levels or hypoglycemia. This can cause more severe night sweats.

3. Food

If we’ve consumed a lot of spicy or heavy food before going to bed, our metabolism is trying to process it. This can cause our body temperature to increase. It’s best to have more substantial meals at lunchtime and light dinners.

4. Maintain A Warm Cover

While warm and cozy beds and sheets are ideal in the winter, the warmer months require changes in bedding. For people who sleep hot, it doesn’t matter what season it is, and they’ll need bedding and pillows to keep them cool and assist them in their sleep at night.

  1. Removing blankets and sheets and wearing fewer clothes in bed will help reduce layers and make your sleep space less suffocating.
  2. It is also essential to consider the type of material you are surrounded by. You are switching from synthetic to natural fabrics like cotton, and linen has been a comfort source.

5. You Should Alter Your Sleeping Position More Often

It’s perfectly normal and even encourages them to move around some during the night. It helps prevent soreness caused by sleeping too long in a single position, aids in keeping air flowing throughout your body, and stops specific areas from accumulating sweat. Healthy adults typically go through 20–30 positions per night.

6. If You Suffer From A Sweating Disorder

Although it’s scarce, there is a chance that you could have hyperhidrosis, the condition where the body’s sweat glands are overly active due to unknown causes.

Advice for people suffering from hyperhidrosis

  • Make sure you purchase high-quality deodorants that are of high-quality. Also, keep in mind that deodorants do not decrease sweating.
  • Take into consideration your clothes. Opt for loose-fitting clothing that is more breathable. For instance, ones with an open knit or loose weave, constructed of thin fabrics, with quick-drying or moisture-wicking properties, or with mesh ventilation panels.
  • Avoid heavy footwear and tightly-fitting socks if you sweat off your feet; select shoes with little to no synthetic materials and socks with moisture-wicking properties.

7. Facing The Inevitable: Flashes & Hormonal Imbalances

Female hormones are frequently responsible in the matter of the regulation of temperature. Studies have revealed that women’s body temperatures tend to rise in the days preceding their menstrual period. Although the menstrual cycle generally isn’t a pleasurable period, with mood shifts and stomach cramps, the additional problems women trigger due to increased body temperature can cause disturbed sleep patterns. Before their monthly menstrual cycle, women feel hotter under the sheets.

In reality, hormone fluctuations affect women of all ages, not only their child-bearing years. Women who are going through menopausal or perimenopausal may experience hot flashes. The blood rushes through these blood vessels, which causes the skin to heat up and flush.

8. Infection

Suppose you’ve checked off each of these possibilities and are trying to figure out why you’re sweaty while sleeping. In that case, it could be because the body is trying to alert you to something wrong if your body is fighting an illness or infection and your temperature rises.

9. Levels Of Psychological Distress

Stress can increase the likelihood that people sweat because the body’s stress response is activated (with the fluctuation in the body’s temperature, heart rate, etc.). It’s normal for people to feel a physiological reaction to the terror of their nightmare, particularly when they’ve had nightmares.

10. Your Bed’s Room Temperature Room 

A dip in temperature can aid your body in preparing to sleep. A relaxed and comfortable room could be helpful. Make sure you have layers available to ensure that should you wake feeling cold later in the night, you can cover yourself with a blanket.

11. The Mattress’s Ability To Regulate Temperature

Certain mattresses can make controlling body temperature more complex than with other types by trapping warmth between the body and the bed. Your body’s heat is transferred to the foam to warm it and conform to the shape of the body. While this could make your mattress more comfortable, this heat can reflect off of your body and cause excessive heat.

12. The choice of comforters and bedding 

A non-breathable fabric (such as polyester) can cause more problems with high body temperatures when you sleep since the body heat will be locked in the cover, and there is no escape route.

  • Choose comfortable wool bedding which will aid your body temperature control and lessen the possibility of nighttime awakenings due to excessive heat.
  • If you choose bedding that keeps you cool while warm and warm when cold, you’ll find yourself less affected by fluctuations in temperature during the night.

Do you have a pet who is comfortable sleeping in your bedroom? The fewer people in your bedroom that can heat the room, the more comfortable! Your cat’s or dog’s heat could make it more challenging to get you to cool down to the ideal temperature for the most restful sleeping.

10. You Are Able To Sleep On The Floor

If you’re sleeping alone and still feeling hot, an alternative is to sleep on your floor. It could be more comfortable than sleeping in a taller bed frame since warmer air rises. If you’re not comfortable sleeping on the floor, it is possible to put your bed on the ground or on an elevated bed frame that is a bit lower than the floor.

11. Affirm your sleep by using a Fan or Dehumidifier

The reduction in humidity and the increased airflow in your bedroom could aid in more restful sleep, particularly in summer, when even the most slumbering sleepers might be sweaty when they wake up. A dehumidifier is a great way to keep humidity levels within 30% to 50%, while a fan can help circulate air throughout the space.

12. Enjoy a Hot Bath

Enjoy a hot bath for at least an hour before going to bed. This can raise your body’s temperature initially; however, do you remember the part where you must leave the tub? This is when your body cools down, and you are prepared for bed.

13. Wear Comfortable Pajamas

The clothing you wear to bed can affect your body temperature and your sleeping comfort. You can benefit from breathable and lighter clothes that absorb moisture, like your bedding. They can improve comfort and reduce heat through the body’s natural process of controlling temperature through sweat.

Heavy materials, like flannel fabric, aren’t ideal for those experiencing the hot summer months. Instead, go for lighter and looser clothes that don’t restrict airflow around your skin.

14. You can sleep with an ice Pack or Damp Compress.

The cooling of certain parts of the body can help reduce your temperature overall. For example, wrap an ice cube in a towel or apply an icy, moist compress on the pulse points on your body, such as your wrists, ankles, and elbows. Try freezing the gel mask and then sleep in it with your face.

15. Test for Fever

Check your temperature. If you notice a fever, you could be suffering from an infection. Drink plenty of fluids and relax at your home. A bathing sponge using lukewarm or warm water could aid in relieving symptoms of fever. There are medications to reduce fever on the market.
