Night Sweating: 5 Causes To Consider

Even if it does not correspond to a serious illness, if you are sweating too often at night for no reason, it is better to check your bedding (mattress & pillows) and consult a specialist for tests.

Night sweating is normal only when the temperature or atmospheric pressure is high. If these factors are not present, it is an abnormal symptom, which must be analyzed.

Too much perspiration is a very common ailment. Sometimes it is the period of a cold or a small infection. This can also be a very recurrent effect during menopause.

However, in any case, it is necessary to have a good diagnosis. The International Society of Hyperhidrosis has conducted studies to better understand this problem.

Although, not everyone who perspires during the night does not suffer from the hyperhidrosis. It is a very common problem of primary attention consultations. This is often due to insomnia or even stress, and this anxiety accumulated because we can’t achieve a night of restful sleep.

In other cases, there are underlying diseases of relative gravity that need to be treated. In this article, we explain 5 causes of night sweating symptom.

1- Night Sweating and Side Effects of Some Medications:

Excess perspiration at night can be the consequence of the side effects of some drugs.

The Department of Psychiatry at the University Of Pennsylvania (USA), it has been shown that many treatments for anxiety and depression trigger an increase in night sweating.

However, this does not happen in all patients. Only between 14% and 20% show an excessive increase in perspiration during the night (pajamas and sheets finish soaked).

Similarly, excessive drug use to treat pain or inflammation may also cause this side effect.

So, do not hesitate to consult a doctor about any symptoms or side effects related to specific medications that you should take for your illness.

2- Night Sweating – Hyperthyroidism

This is, without a doubt, the most common cause of night sweating. It is clear that hyperthyroidism has other obvious symptoms such as fatigue, weight gain, capillary fragility, and such common temperature disorders.

It should be known that when the thyroid gland suffers from an impairment linked to the hormone thyroxin, our metabolism becomes unbalanced. One of the main consequences is intolerance to heat and excessive perspiration.

Similarly, we also notice palpitations when we are in bed, ringing in the ears and insomniac episodes.

3- Night Sweating – Hyperthyroidism

We told at the beginning of this article that night sweating is an indicator of some types of more serious diseases.

Lymphomas are one example. It is cancer that starts in lymphocytes, which are an indispensable part of the immune system.

The lymphatic system or the spleen can be affected by this type of disease, where night sweatings are usual.

In general, the main indicator experienced by patients with these lymphomas is inflammation of an armpit or groin ganglion.

However, you should know that this is a type of cancer that responds well to treatment and has a high life expectancy.


4- Night Sweating – Hypoglycemia

Night sweating is also a common symptom of hypoglycemia.

Patients with type 1 diabetes, for example, often suffer from episodes of excessive sweating at night, because they suffer from imbalances in their glucose levels. If that happens, it’s for a very specific reason. The pancreas does not produce enough insulin. As a result, perspiration is created to balance this internal alteration.

5- Night Sweating – Gastric Reflux or Poor Digestion

It must have happened to you already. You eat in excess or something that makes you sick. One moment of the night, you wake up with a general feeling of discomfort and completely soaked in sweat.

It is a way our body responds to an imbalance, threat or interior alteration.

Similarly, it should be known that the disease of gastric reflux is also related to this symptom.

Also, note that the exhaustion, the pain in the chest and the problems to breathe are too. If you suffer from this regularly, consult a specialist.

Once the disease is diagnosed, with good treatment, you will gain in quality of life.


To conclude, never normalize this type of symptoms. Sweating at night, if it is not hot, is not normal.

Consult your doctor and explain how you feel and what happens to you. Always use quality Mattress and Coldest Pillows.
