• Perimenopausal women's psychological symptom severity is 1.5x higher than premenopausal women (psychological domain score 7.3 vs 4.8), per a global digital study using Flo Health data, published in Menopause (the Journal of the Menopause Society), July 2026.
• Every individual psychological symptom measured was elevated during perimenopause compared with premenopause – not just a few headline symptoms.
• The study is one of the first to compare psychological symptoms across the transition at global scale using app-based longitudinal data.
• The 1.5x severity finding is population-level evidence that worsening mood in perimenopause is a measured phenomenon, not a character flaw or 'all in your head.'
