Night Sweats

Night Sweats are also known as Nocturnal Hyperhidrosis, which generally involves excessive sweating during sleep. People who suffer from this condition usually wake up in the middle of the night to find both their sleepwear and sheets drenched, regardless of their bedroom’s temperature.

Sweating excessively during sleep may, or may not, be associated with excessive perspiration during the day. Flushing, which is a warmth and redness of the face or trunk, can be very difficult to distinguish from night sweats and may therefore be accordingly attributed wrongly as such.

What Are The Symptoms?

• Shaking and chills;
• Fever;
• Hot flashes;
• Mood changes;
• Unexplained weight loss.

Sometimes excessive nighttime sweating do not involve any obvious signs and are neither caused by any specific underlying medical conditions. In this case, the condition is called Idiotpathic Hyperhidrosis, which simply occurs occasionally (but chronically) and is more of an annoyance than an alarming sign.

What Are The Causes Of This Affliction?

Night Sweats are usually innocuous; however, sometimes they can be a symptom of underlying illnesses and can occur for the following reasons:

• Sleep apnoea;
• Menopause and perimenopause;
• Hypoglycaemia (low blood sugar);
• Alcohol or drug abuse, especially heroine;
• Cancer, particularly lymphomia and leukaemia;
• Medication such as antidepressants or aspirin;
• Hormone disorders such as an overactive thyroid gland;
• Infections such as tuberculosis and HIV;
• GORD (gastro-oesophageal reflux disease);
• Rarely, neurologic conditions such as autonomic dysreflexia.

All these conditions will display other symptoms accordingly and can only be diagnosed by your GP. Please do not use this page to self-diagnose your condition and seek professional medical advice at all times.
