Infections

Night sweats are mostly associated with an infection like tuberculosis. However, there are bacterial infections like endocarditis or inflammation of the heart valves, abscesses, and osteomyelitis or swelling in the bones could cause excessive sweating. And also, night sweats are as well a symptom of HIV infection.

Idiopathic Hyperhidrosis

This one is a condition wherein the body produces too much sweat chronically without any identifiable cause.

Medications

If you are taking some medicines, then it could lead to night sweats. One of the common types of drug which could lead to night sweats is antidepressant medications. Some other psychiatric drugs would have also been associated with excessive sweating. If you are taking medicines to lower fever like acetaminophen and aspirin, then sweating is also possible.

Hormone Disorders

Flushing or sweating could be seen with various hormone disorders such as hyperthyroidism, carcinoid syndrome, and pheochromocytoma.

Hypoglycemia

Indeed, low blood sugar could be a reason for sweating. Those who are taking oral diabetes medications or insulin might have hypoglycemia at night which is also accompanied by sweating.

Neurologic Conditions

Increased sweating and night sweats might also be due to some neurologic conditions such as autonomic dysreflexia, stroke, post-traumatic syringomyelia and autonomic neuropathy.

These are the causes of excessive sweating or night sweats as you sleep at night. Beware of these causes for you to answer the query “why do I sweat so much when I sleep?”

For some other factors in lifestyle which might lead to night sweats include the following:

  • If you will do an exercise before you go to bed, night sweating is possible. Exercise would increase the temperature of the body and will make you warm. So, in that case, high level of blood circulation could cause drenching night sweats. It could be avoided if you will do an exercise in the evening or the morning instead. You need to avoid doing specific activities before going to bed.
  • The body could be warm through eating something that has warm efficacy or those hot beverages. You should avoid the idea of eating dry fruits such as dried figs and nuts that could warm the body creating heat leading to night sweating.
  • Of course, eating spicy items once you are about to sleep could increase the blood flow and could also be a cause of gastro-esophageal reflux momentarily resulting in excessive sweating. That’s why you have to beware of eating spicy food items.
  • High thermostat setting and unavailability of proper air could make the room very warm as well. With that, high temp could lead to drenching night sweats resulting in an uncomfortable night. You might also be having too many bedclothes. You should also avoid wearing socks or too many sweaters as you sleep at night.
  • And finally, though this sounds funny, horrific dreams and nightmares are also the reasons behind sweating so much as you sleep.

You should at least know these factors in order not to conclude anything about your excessive sweating during your sleep at night.

How to Treat Night Sweats

Well, we also need to discuss the treatment necessary for night sweats. And this treatment depends on the underlying causes like adjusting medications, correcting hormone irregularities and also attending to some contributing factors.

Once there is no direct or determined cause of this excessive sweating, the treatment might consist of both management and prevention methods. Some of these include:

  • Avoiding over bundling or utilizing a heavy comforter
  • Applying a clinical strength antiperspirant to some parts of the body which are most susceptible like your underarms, back, hairline, chest, feet, hands or groin

  • Come on right after the menopause symptoms have been absent for almost months to years

Tips on How to Deal with Night Sweats Properly

But of course, there are specific ways on how to stop night sweats, so you could sleep cool, stay dry and wake up in the morning not needing a shower immediately.

Eliminate Triggers

Whatever the causes may be, there are some things which could be done in finding relief to night sweats. First things first! If you just experience night sweat out of the blue, its best to see a doctor to rule out anything serious.

If not, how will you sleep dry and cool at night? You should know that night sweats could be triggered by some specific stimuli. For those with night sweats, you should avoid the following as you prepare to sleep:

  • Don’t wear restrictive or tight pajamas
  • Don’t smoke or even inhaling secondhand smoke
  • Don’t use massive sheets or blankets on the bed
  • Don’t eat spicy food around 4 hours before going to sleep
  • Don’t drink alcohol or caffeine at about 8 hours before bedtime
  • Keep the stress under control
  • Keep the temperature of your room at 65 F

These are some of the triggers that you should avoid for you to stop night sweats continuously.

Control What Touches the Skin

Sleeping on performance fabrics is considered as one of the best ways to stop excessive sweating and stay dry and cool as you sleep at night. If you think that cotton is the best fabric to consider in keeping cool since it breathes, you are probably wrong! In fact, it is the worst fabric that you could sleep in once you are suffering from night sweats.

Why do I say so? Well, cotton fabrics do not breathe or wick the moisture away. Once cotton gets wet, it would stick to the body. And nobody would want the gross feeling of the wet sheets or pajamas that stick to places wherein the sun doesn’t shine. So, better not choose cotton.

You must use pajamas that are made for night sweats. Use those pajamas which offer a moisture wicking smart fabric that draws the humidity and heat away from the body and will keep you fresh. And you can combine the said pajamas with some temperature regulating sheets.

Make Over Your Bed

Mattresses and pillow could mean the difference between being comfortable and cool and sticky and hot. Mattresses are considered as a big-ticket item and sometimes being sweaty and hot might not be enough reason for you to buy a new one. At least, consider buying mattresses that are made for hot sleepers.

If you do not buy a new mattress, some options could be considered like cooling your mattress off using a cooling mattress pad, keeping a cool head utilizing a pillow pad, using a bed fan to stay cool and using only sheets that are made for night sweats.

Use Essential Oils

For a natural way of relieving night sweats, you can use cooling essential oils and massage them into your skin. Some options are peppermint, clary sage and geranium oil. You only need to mix a few drops along with a high-quality carrier oil then massage yourself before going to bed and when night sweats happen.

Establish Cool Habits

You should avoid exercising or even doing difficult things before six to eight hours before going to bed. It is best to begin eating a healthier diet in order to minimize sweating, and you must also develop a nightly meditation routine as for reducing daily stress as well.

Final Thoughts

Again, why do I sweat so much when I sleep is a question that needs to be answered. And good to know, I have provided you the reasons behind the said condition. You should bear in mind that night sweats aren’t a serious issue all the time. In some cases, it is a common phenomenon which a person might experience at least once a month or even a year.

Nevertheless, persistent night sweats might also be a matter of concern. There might be different reasons behind it and should be treated based on the advice of the doctor. Bear in mind that you must not start any treatment by relying on the symptoms and the stated conditions. Instead, consultation along with an experienced doctor is needed.
