This unconventional type of portrait of a sleeping woman was created by the famous Dutch artist, Rembrandt (1606-1669). The drawing is both affectionate and yet not a precise likeness of the sitter. She can only be recognised in generalised terms as Hendrickje Stoffels (about 1626-63), wife of the artist.
The study is drawn entirely with the brush in brown wash with some white bodycolour, which is experimental for Rembrandt who mostly used pen or chalk in his drawings. This technique is also most appealing to the modern eye, and reminds us of oriental drawings and calligraphy made with the brush.
With the tip of the brush and only a few broad strokes Rembrandt has rapidly and skilfully outlined the body of the sleeping woman. He also used the white of the paper to create not just her form but also the atmosphere surrounding her.
Some women who have trouble sleeping may use over-the-counter sleep aids such as melatonin. Others use prescription medications to help them sleep, which may help when used for a short time. But these are not a cure for sleep disturbances, such as insomnia, and should not be used long term.
The researchers cautioned that their study evaluated sleep position only up to 30 weeks of pregnancy and does not provide information on whether back or right-side sleeping in late pregnancy could increase the risk of birth or pregnancy complications.
Many physicians advise pregnant women to sleep on their left side. Previous studies have linked back and right-side sleeping with a higher risk of stillbirth, reduced fetal growth, low birth weight, and preeclampsia, a life-threatening high blood pressure disorder that affects the mother. Researchers have hypothesized that, with these sleep positions, the increasing weight of the uterus during pregnancy could compress the aorta (the central artery conveying blood to the upper and lower abdomen) and the inferior vena cava (the central vein returning blood from the lower abdomen to the heart).
The researchers concluded that sleeping position during early and mid pregnancy does not appear to affect the risk of complications. They added that the findings may help to reassure pregnant women, particularly those who have difficulty sleeping on their left side and those who have trouble controlling their position while asleep.
The scientists used weight, height, waist and hip circumference, and body mass index measurements taken at baseline, as well as self-reported information on weight at baseline and follow-up five years later. Using this information, the scientists were able to study obesity and weight gain in women exposed to artificial light at night with women who reported sleeping in dark rooms.
"Although poor sleep by itself was associated with obesity and weight gain, it did not explain the associations between exposure to artificial light while sleeping and weight," said corresponding author Dale Sandler, Ph.D., chief of the Epidemiology Branch at the National Institute of Environmental Health Sciences (NIEHS), part of NIH.

Looking toward the West Bench of Yountville, snug upon the Mayacamas mountain range, the distinct profile of a woman at rest on her side framed by distinctive foothills explains the name of this meticulously farmed vineyard. There are multiple clones of Cabernet Sauvignon planted in small blocks across 50 acres here, including several favorites of winemaker Harry Hansen, who often selects blocks with Clone 2, known for small clusters and small, intensely flavored berries with a history in Napa and Sonoma dating to the 1880s, aromatic Clone 22 and Clone 30, with local roots in the Stags Leap District from the See Ranch.
As a woman nears menopause, her hormone levels fluctuate dramatically, causing night sweats and hot flashes, which can wake the brain during sleep. In addition, lower levels of progesterone make some women irritable and less able to relax.
Currently, only a limited number of studies are available on this topic. More research is needed to be certain whether or not there is an association between stillbirths and sleeping positions up to 30 weeks of pregnancy.
After that, you may have heard that studies link sleeping the whole night on your back to stillbirth. Before you get too worried, understand that the studies are small and there may be other factors like sleep apnea at play.
Plus, there are other issues with sleeping on your back. This position may contribute to back pain, hemorrhoids, digestive issues, and poor circulation. It may also make you feel lightheaded or dizzy.
Physiologic studies suggest that sleep restriction has metabolic effects that predispose to weight gain. The authors investigated the association between self-reported usual sleep duration and subsequent weight gain in the Nurses' Health Study. The 68,183 women who reported habitual sleep duration in 1986 were followed for 16 years. In analyses adjusted for age and body mass index, women sleeping 5 hours or less gained 1.14 kg (95% confidence interval (CI): 0.49, 1.79) more than did those sleeping 7 hours over 16 years, and women sleeping 6 hours gained 0.71 kg (95% CI: 0.41, 1.00) more. The relative risks of a 15-kg weight gain were 1.32 (95% CI: 1.19, 1.47) and 1.12 (95% CI: 1.06, 1.19) for those sleeping 5 and 6 hours, respectively. The relative risks for incident obesity (body mass index: >30 kg/m(2)) were 1.15 (95% CI: 1.04, 1.26) and 1.06 (95% CI: 1.01, 1.11). These associations remained significant after inclusion of important covariates and were not affected by adjustment for physical activity or dietary consumption. These data suggest that short sleep duration is associated with a modest increase in future weight gain and incident obesity. Further research is needed to understand the mechanisms by which sleep duration may affect weight.
Data analyses revealed that women with sleeping difficulties had higher BMIs, lower physical activity, and poorer diets, on average. Researchers also found that those who struggled with sleep were likelier to smoke and drink alcohol and have previously gone through menopause.
During the first trimester, it is safe for a woman to sleep in whatever position she feels comfortable in, whether this is on her back, side, or stomach. Any combination of the above positions is also fine.
As a woman reaches the second and third trimesters, it is ideal to sleep on the left side. Being in this position maximizes blood flow to the uterus without putting pressure on the liver. Women who experience hip or back pain during pregnancy may find that placing a pillow or two between the knees or bending the knees during sleep can help provide relief.
Many pregnant women worry that sleeping on their stomach will harm the developing fetus. However, the uterus protects the fetus well, and there is no reason to avoid sleeping on the stomach during the first trimester.
However, this study looked at the position in which a woman fell asleep rather than the position she moved into during sleep. There is little evidence that accidentally rolling onto the back during pregnancy will cause lasting harm. As a result, not all experts agree with the advice to avoid sleeping on the back.
A 2018 University of Utah interview with three high risk pregnancy specialists emphasizes that one study linking back sleeping to stillbirth did not control for other factors. The specialists also note that even in women who sleep on their backs, the risk of stillbirth remains low.
"You can't walk while black. With Ahmaud, you can't jog while black. Driving while black," Crump said during a news conference. "But Breonna Taylor was sleeping while black in the sanctity of her own home."
Police responded to the Virginia Beach Oceanfront around 3:30 a.m. Saturday after getting a call that a lifeguard stand had fallen on the woman. The woman, identified as 28-year-old Chelsea Moles, was pronounced dead at the scene, according to Virginia Beach police.
To ensure that you will be warm when you sleep (especially when the ground is colder), it is essential to know how well your sleeping mat resists heat loss into the ground. This resistance is known as an R-Value. A laboratory-tested R-Value is the only way to measure resistance to heat loss. Sea to Summit has always provided independent lab-tested R-Values for its sleeping mats. Since January 2020 we have used the industry standard ASTM F3340-18 test to provide R-Values for our mats. There are other factors which will determine how well a sleeping mat will insulate; but the standardized ASTM R-Value test means that you can compare resistance to heat loss in sleeping pads across different brands.
Yes! The supplied stuff sack features an integrated Airstream Pump which will quickly and easily inflate the sleeping pad. This means no hard work and dizziness for you, and practically no condensation moisture inside the pad.
Yes. This sleeping pad features two types of insulation to prevent radiant and convective heat loss. The tested R-Value of 3.5 and the lack of internal air movement means minimal loss of warmth, making this pad great for 3-season use.
A recent study looked at how animal-assisted activities impacted depressive symptoms in humans. They found that people who performed activities or therapy with dogs reported fewer depressive symptoms.
If simply interacting with a dog can treat depression, imagine what sleeping next to one can do! Their presence helps us relax and increases our flow of oxytocin, the love chemical. This essentially makes your dog a living antidepressant!
Building on the fact that sleeping with dogs increases the flow of oxytocin, this also has a profound impact on how deeply we sleep. Sleeping with your dog, and the chemicals that accompany the experience, promote theta brainwaves, which are known to occur during the REM stage of sleep.
Studies have shown that when dogs are with their owners their heartbeats sync up. This is further evidence of the calming effects the presence of a dog can have on the human brain. So, next time you are sleeping near your dog, imagine your hearts beating in unison while you experience the deepest, most rejuvenating sleep.
