“He’s just a cute happy boy, I couldn’t have asked for anything more,” she said.

But her journey to motherhood was anything but easy. Alvarado experienced two miscarriages, and when she got pregnant with Milo, she was diagnosed with perinatal depression.

Alvarado took part in a clinical trial at Northwell Health testing a treatment called “bright light therapy.” For 30 minutes every morning, Alvarado exposed herself to a light nicknamed “sun in a box” to help reset her circadian rhythm.

“That sleep and wake cycle is disrupted in women who are depressed in pregnancy and it’s by retraining, resetting the clock to where it should be that it is to relieve the symptoms of depression,” said Dr. Kristina Deligiannidis, an associate professor at The Feinstein Institutes for Medical Research.

Dr. Deligiannidis said having a variety of treatment options for perinatal depression is critical.

“Some women, they may want to engage in individual or group talk therapies. Other women may choose antidepressants. We want to provide also noninvasive treatments that are very low risk for both mom and for her baby.”

Alvarado said she noticed a “huge difference” with the light therapy.

“It really gets you to wake up, it’s like going outside and going for a walk because you’re shocked by like the sunlight.”

Combined with antidepressants and traditional therapy, Alvarado said the difference was night and day.

“I can’t even recognize the person I was when I was pregnant,” she said. Alvarado said better sleep helped her function better, so she could focus on her mental health and on being a mom.
