Early Perimenopause
Cycles start to shift. Sleep and mood move first.
Early perimenopause typically begins in the late 30s to mid-40s. Cycles may become irregular, and subtle hormonal changes can cause mood shifts, sleep disruption, and fatigue. Most women don't yet experience hot flashes but notice changes in energy and cycle regularity.

What the research says
Evidence for early perimenopause
Early Perimenopause Symptoms Can Appear Before Hot Flashes
In this cross-sectional analysis of Australian women without vasomotor symptoms, early perimenopause was defined by a menstrual-cycle variation of at least 7 days, and its symptom profile differed little from the late reproductive stage with changed flow. The findings indicate that changed flow alone is not a clear marker of transition onset and cannot establish that a particular symptom was caused by menopause.
Bresolin S, Islam RM, Bond M, Davis SR. Symptom profiles in the late reproductive stage, earlier premenopause and early perimenopause in the absence of vasomotor symptoms: a cross-sectional study. BMJ Sex Reprod Health. 2026;52(3):192-199. doi:10.1136/bmjsrh-2025-203075. PMID: 41813093.
Exercise May Ease Depression During Perimenopause
A meta-analysis of 21 randomized trials involving 1,398 Chinese perimenopausal women found that exercise interventions reduced depressive symptoms versus control conditions. Because results varied substantially between studies and publication bias was possible, the review cannot identify an optimal exercise prescription.

Herbal Supplement Improves Sleep and Mood in Postmenopausal Women
A 28-day randomized, double-blind, placebo-controlled trial of 140 peri- and postmenopausal women found that Khapregesic® (Khaya senegalensis) supplementation significantly improved psychological symptoms, fatigue, and sleep disturbances compared to placebo in the postmenopausal subgroup. While no overall group effect was detected across the full cohort, the subgroup findings suggest this herbal preparation may offer targeted benefits for early perimenopause-related mood and sleep disruption.
