Night Sweats.

[Big Guy]

Anyone deal with it and can it be Sleep Apnea associated? Saw in another post that someone mentioned waking up with a sweat soaked t-shirt. 

I've been dealing with it for quite a while. It's not terribly bad, but I wake up and have to push the bed covers down so I can cool down. A couple of months ago, I woke up with the worst case I have experienced. Not only was I covered in sweat, so were the sheets on the bed. 

I had to wake my wife up and tell her what was going on. I helped her change out the bedding and I took a shower. For the rest of the night, I did okay. 

I had a Catheter (Cardiac) Ablation performed on Sept. 19th. I did mention it to my doctor, but he didn't seem to be all that concerned. Since having had the Ablation, the occurrence of them has dropped a great deal. 

I was just curious if anyone on here deals with it, and if so, for how long, and what have you done to remedy it? 

That one night a while back, had me concerned. It was pretty severe.

Want to make a joke about "Sweating" the bed, but I legit did it a lot before I started using the cpap. I had not honestly considered the correlation until I saw that myself but I can't say I've experienced a case of it since I started.

I also get hot during the night and if I do not remove blankets as the bed warms up I will sweat. I have  read somewhere is that it can also be a age problem.

I sweat a couple times a night, not to a soaking state, but just HOT.  I am a post menopausal woman, but it feels "hot flash" like. I do associate it with the apnea, which for me, is not controlled quite yet (moving to an ASV machine, as I have complex apnea, with many central apneas and my current APAP is not working out). I understand sweating can be connected to apnea and the surges of adrenaline or from oxygen drops (hypoxia).

If you have not, please get some blood testing done as sweating at night can also be associated with blood disorders or leukemia... not saying you have that, but get it checked.

I've had quite a bit of lab testing done this summer, not specifically for Night Sweats, but for AFIB issues. Also, some MRI's and such for the same reason. 

I have a follow-up appointment coming up in early Feb. with our family doctor. I'll being it up with him and see what he has to say.

Other than environment and underlying medical issues, such as infections, disease, medicine, and supplements, there appears to be a link between OSA and night sweats. 

Nocturnal sweating--a common symptom of obstructive sleep apnoea: the Icelandic sleep apnoea cohort

Abstract

Objectives: To estimate the prevalence and characteristics of frequent nocturnal sweating in obstructive sleep apnoea (OSA) patients compared with the general population and evaluate the possible changes with positive airway pressure (PAP) treatment. Nocturnal sweating can be very bothersome to the patient and bed partner.

Design: Case-control and longitudinal cohort study.

Setting: Landspitali-The National University Hospital, Iceland.

Participants: The Icelandic Sleep Apnea Cohort consisted of 822 untreated patients with OSA, referred for treatment with PAP. Of these, 700 patients were also assessed at a 2-year follow-up. The control group consisted of 703 randomly selected subjects from the general population.

Intervention: PAP therapy in the OSA cohort.

Main outcome measures: Subjective reporting of nocturnal sweating on a frequency scale of 1-5: (1) never or very seldom, (2) less than once a week, (3) once to twice a week, (4) 3-5 times a week and (5) every night or almost every night. Full PAP treatment was defined objectively as the use for ≥4 h/day and ≥5 days/week.

Results: Frequent nocturnal sweating (≥3× a week) was reported by 30.6% of male and 33.3% of female OSA patients compared with 9.3% of men and 12.4% of women in the general population (p<0.001). This difference remained significant after adjustment for demographic factors. Nocturnal sweating was related to younger age, cardiovascular disease, hypertension, sleepiness and insomnia symptoms. The prevalence of frequent nocturnal sweating decreased with full PAP treatment (from 33.2% to 11.5%, p<0.003 compared with the change in non-users).

Conclusions: The prevalence of frequent nocturnal sweating was threefold higher in untreated OSA patients than in the general population and decreased to general population levels with successful PAP therapy. Practitioners should consider the possibility of OSA in their patients who complain of nocturnal sweating.

Sleep-related sweating in obstructive sleep apnoea: association with sleep stages and blood pressure

Abstract

The aim of this study was to investigate sleep-related sweating as a symptom of obstructive sleep apnoea (OSA). Fifteen otherwise healthy male non-smoking patients with untreated moderate-to-severe OSA underwent polysomnography, including measurements of skin and core body temperature and electrodermal activity (EDA) as an objective indicator of sweating. Evening and morning blood pressure was measured as well as catecholamines in nocturnal urine. All measurements were repeated after 3 months on successful continuous positive airway pressure (CPAP) treatment. The untreated OSA subjects had a mean (+/-SD) apnoea-hypopnoea index of 45.3 +/- 3.9 and a mean EDA index during sleep of 131.9 +/- 22.4 events per hour. Patients with higher EDA indices had higher systolic blood pressure in the evening and morning (P = 0.001 and 0.006) and lower rapid eye movement (REM) sleep percentage (P = 0.003). The EDA index decreased significantly to 78.5 +/- 17.7 in the patients on CPAP treatment (P = 0.04). The decrease correlated with lower evening systolic and diastolic blood pressure (P = 0.05 and 0.006) and an increase in REM% (P = 0.02). No relationship was observed between EDA and skin or core body temperature, or to catecholamine levels in urine. OSA patients who experience sleep-related sweating may have increased blood pressure and decreased REM sleep compared with other OSA patients. CPAP treatment appears to lower blood pressure and increase REM sleep to a higher extent in these patients compared with other OSA patients.

Interesting......thanks for posting that up.
