What is the suggested lux range for perinatal bright light therapy effectiveness?

The suggested lux range for effective perinatal bright light therapy is generally around 7000 to 10,000 lux. This range has been identified in various studies and clinical guidelines as effective in treating symptoms related to mood disorders, particularly during the perinatal period. Bright light therapy has gained traction as a non-invasive treatment to help regulate circadian rhythms and improve mood, especially in cases of seasonal affective disorder and postpartum depression.

While treatments above 10,000 lux exist, they are typically used for more severe cases or specific symptoms, and may not be necessary for all patients. Additionally, too high of a lux level can lead to discomfort or other side effects, making the mid-range of 7000 to 10,000 lux the most recommended for therapeutic use. This range balances efficacy with patient comfort and safety, ensuring that light exposure is sufficient to elicit a positive therapeutic effect without overwhelming the individual.
