Night sweating or Nocturnal hyperhidrosis is the condition in which an individual suffers from the episodes of sweating during night that soak the nightclothes and bedding irrespective of the surrounding temperature.
The true night sweats refer to the severe hot flashes that occur during night and can drench the bed sheets and sleepwear, the condition which is not the result of an overheated environment.
Excessive night time sweating may or may not be linked to the excessive sweating during the day time. The facial warmth and redness is quite difficult to differentiate from the night sweats and therefore may be wrongly attributed. The sweating at night is often associated with some underlying cause.
The excessive night sweating is usually harmless however sometimes it can be a symptom of some underlying diseases. There can be following reasons for the nocturnal hyperhidrosis;
- Medications causing night sweats
- Intake of antidepressants
- Taking drugs for regulating hormones
- Drugs that decrease the sugar level in your blood
- Medical conditions that cause excessive night time sweating
Medical conditions causing excessive night sweats include the following;
- Sleep disorders
- Autonomic neuropathy
There are different symptoms that may occur in association with underlying cause of the night sweating. For instance;
- Along with night sweats fever can also develop as a result of cancers and infections.
- Sometimes chills and shaking can also accompany it.
- Unexplained weight loss can also occur along with cancers or lymphomas.
- The menopausal transition can be accompanied by menopause symptoms like dryness of vagina, hot flushes in day time and changes in mood.
- Night sweats can be a result of the coordinated side effects of medications taken.
- Certain conditions that accelerate sweating in general can also result in sweating at some other hours of the day.
Sometimes, there are not clear signs of night time sweating and is not even a cause of any particular underlying medical conditions. If this is the case, it is referred to as Idiopathic Hyperhidrosis that occurs occasionally yet chronically and is more than just an annoyance.
