Just a short blurb today to share an interesting Huffington post article on the connection of blue light with melatonin secretion (the hormone that induces sleep) and thus postpartum depression (PPD). The title of the article is “The Connection Between Blue Light and Postpartum Depression” by Matt Berical.
I’ve always been fascinated in the biology behind PPD, in particular insomnia as a symptom, hence here I am popping onto my blog this July 4th weekend ever so quickly to blog. I had previously blogged about blue light in my post from 2 years ago titled “Sleep is So Important, Especially to the New Mom.” If insomnia is plaguing you on a antepartum (or prenatal) or postpartum (or postnatal) basis, or if you are an expectant mom who just wants to be in the know to reduce the chances of PPD hitting you from left field like it does for so many moms, then please read the Huffington Post article and my previous blog post.
I had not known what depression and insomnia were like before I was hit from left field with both, so I’m always happy when I see information made available to the public to educate people. An important word I’ve heard used before, just not in conjunction with something like PPD prevention, is prophylactic. It’s a synonym, after all, for preventive measure, which in the case of pregnancy prevention comes in the form of a condom and/or the pill, but in the context of PPD prevention comes in the form of knowledge of symptoms, where/how to get treatment, lining up adequate social/emotional/practical support, and if you want to avoid disruption of sleep, orange-tinted sunglasses that can be effective in blocking blue light. These sunglasses are recommended for anyone that has to either stay up late on a regular basis, like teenagers studying and being on computers (which emit blue light), to expectant moms who have difficulty sleeping due to having to get up in the middle of the night to go to the bathroom and new moms who have to wake up every 2-3 hours to feed their babies.
Whether it’s the anxiety that comes with new mom challenges or the hormonal fluctuations and decrease in serotonin and/or melatonin–both of which are hormones critical for sleep–sensitivity to circadian rhythm changes are further aggravated by exposure to blue light, a biological trigger to wake up, which means that repeated exposure to it during the night can mess with our circadian rhythms and melatonin production.
And hence, insomnia, which for me was my very first PPD symptom.
