Shining a Light on Hope: How Light Therapy Can Help Perinatal Depression

Kim Berrio is a Registered Nurse in the final months of her Masters of Social Work placement. Here she shares some tips and information about light therapy.

Perinatal depression, a mood disorder that affects women during pregnancy and after childbirth, is a surprisingly common condition. Studies suggest that up to 20% of expectant and new mothers experience symptoms of depression. Traditional treatments for perinatal anxiety and depression, such as medication and therapy, can be helpful. In addition to these interventions, a promising adjunctive therapy can be applied to your routine: light therapy. Light therapy has been shown to be effective in treating seasonal affective disorder (SAD), a type of depression that occurs during the winter months. The research suggests that it may also be beneficial for perinatal depression, and can include benefits such as increased energy, facilitation of better sleep, reduction in symptoms of anxiety and in some cases, help provide pain relief. 

Why Light Therapy?

Light therapy is a safe, non-invasive, and home-based treatment that involves regular exposure to bright light. There are several reasons why light therapy may be a good option for women with perinatal depression:

Fewer side effects: the non-invasive nature of light therapy provides minimal side effects

Accessibility: light therapy can be done at home, most often in the morning hours; a great time to carve out some personal time spent with a cup of coffee or tea and a journal

Cost-effective: light therapy units are a one-time investment, making them a more cost-effective option 

How Does Light Therapy Work?

Light therapy is most beneficial when used in the early morning hours (6am-8am) for at least 30 minutes. The exact mechanisms by which light therapy works in perinatal depression are still being studied, but researchers believe it may have an impact on:

Serotonin levels: light exposure is thought to increase serotonin levels in the brain, which can improve mood and well-being

Circadian rhythms: light therapy can help regulate the body's natural sleep-wake cycle, which can be disrupted in women with perinatal depression

If you are struggling with perinatal depression, talk to a professional about whether light therapy might be a right option for you. With its ease of use, safety profile, and promising results, light therapy may be a ray of hope in your journey towards healing.
