Cold Night Sweats: A Sign of Low Body O2
Night sweats (or sleep hyperhidrosism or cold night sweats) are defined as periods of nighttime sweating that makes your nightclothes or bedding wet even in conditions of normal thermoregulation.
One of the most common causes of night sweats in women over 40 is the hormonal changes related to menopause and perimenopause. There are many medical conditions that can cause night sweats in men and women. They range from infections and hypoglycemia and to HIV/AIDS and cancer.
Many medical drugs and even supplements (antidepressants, antipyrectics, hormones, hypoglycemic agents, tamoxifen, nitroglycerine, niacin, and Viagra) exacerbate or even trigger problems with night sweats.
Key causes of night sweats
However, in the overwhelming majority of cases the key underlying cause of night sweats is low body oxygenation due to positive static electricity of the human body, mouth breathing, supine sleep, chest breathing and hyperventilation. All these factors lead to low tissue O2 concentrations and promote chronic inflammation, immunosuppression, dysregulation of hormonal changes, and many other pathological effects.
The image on the left shows the effects of overbreathing in a person who breathes more than the medical norm. A similar picture takes place during night sweats due to heavy and fast breathing.
The Table below explains why night sweats are very common in modern people (both men and women), but were very rare during the first decades of the 20th century.
Nearly all cases of night sweats occur in people who have less than 20 seconds for the body-oxygen test, while the norm is about 40 seconds. (Dr. Buteyko's norm is 60 s.) Night sweats become severe, when the body-O2 content is less than 10 seconds or more than 4 fold below the norm.
How to stop night sweats
There are various methods and techniques that immediately lead to nearly double
reduction in intensity and severity of night sweats. Thus, you can stop night
sweats using the following techniques:
- Grounding your body for normalization of its electrical properties (Earthing)
- By preventing of mouth breathing
- By preventing of supine sleep
- Simple breathing exercise to reduce severity of night sweats (the same exercise is used to stop cramps and muscle spasms).
However, in order to stop night sweats completely, one needs to get up to 25-35 seconds for the morning body-oxygen-test results. For example, people with cancer do not experience night sweats when they get about 20-25 s for their body-oxygen test (with daily CPs even higher). However, menopausal hot flashes require up to 35 s for the morning body O2 in order to disappear. This project may take some weeks or months. The details are provided on pages of this site. Thousands of people eliminated or stopped their night sweats completely using the Buteyko breathing method, and other techniques provided here.
