A recent study published in the BMC Public Health suggests higher light exposure at night and poor sleep quality are associated with poorer mental health outcomes during the second and third trimesters of pregnancy.
For a long time, researchers have known that sleep has a complex relationship with psychological wellbeing, one that other factors can mediate. Increased exposure to artificial light at night affects our circadian rhythms and melatonin production, affecting sleep quality and, thus, mental health.
Due to the biological, hormonal, and other life changes during pregnancy, pregnant women are particularly vulnerable to higher levels of depression and stress. Still, the role of light in mediating these effects has not been well-studied. Therefore, knowing more about the links between light exposure, sleep quality, and mental wellbeing during pregnancy is particularly important.
In the present study, researchers in Malaysia and Japan collected detailed data on light exposure, sleep quality, and mental health from pregnant women. The women who participated in the study were aged between 20 and 48 years and were in their first pregnancy. They did not have conditions such as gestational diabetes, hypertension, or anemia, which could also affect their outcomes.
The article explores the potential benefits of reducing light exposure during pregnancy in improving both sleep quality and mental health. Research suggests that minimizing exposure to artificial light, especially during the night, can positively impact the sleep patterns of pregnant individuals. Sleep disturbances during pregnancy are common and can affect mental well-being.
The piece elaborates on how reduced light exposure, particularly at night, can influence the production of melatonin, a hormone essential for regulating sleep. Enhancing melatonin levels by minimizing light exposure might improve sleep quality, subsequently positively affecting mental health.
The article advocates for expectant mothers to adopt habits that limit exposure to artificial light, especially in the evening, to potentially alleviate sleep issues and support mental wellness during this critical period.
