A Review on Screen Time and Endocrine Rhythms: Unraveling Hormonal Imbalance in Digital Lifestyles

Author(s) Dr. Y. Shanti Prabha, Ms. Nikkula Bhavana

Abstract Modern lifestyles have been transformed by the quick spread of digital technology based on screens, but this has also brought about hitherto unheard-of difficulties for maintaining physiological homeostasis, especially with regard to circadian and endocrine cycles. This review examines the growing body of research showing that excessive screen time and artificial light exposure, particularly in the evening, alter endogenous hormone cycles that control metabolism, sleep, stress response, and reproductive health. Digital gadgets' artificial light inhibits melatonin secretion, which delays the onset of sleep and changes the architecture of sleep. Additionally, by changing the dynamics of leptin, ghrelin, and insulin, screen-induced circadian misalignment raises the risk of obesity, insulin resistance, and type 2 diabetes by contributing to metabolic disorders. Chronic screen time and sedentary behaviour have been linked to changes in reproductive hormones, such as luteinizing hormone (LH), follicle-stimulating hormone (FSH), oestrogen, and testosterone, which have a negative impact on menstrual cycles and fertility. In the context of our increasingly digitalised environment, it is essential to comprehend these connections in order to create measures to prevent endocrine disruption.
Keywords Screen time; Hormonal imbalance; Melatonin suppression; Digital lifestyle; Endocrine disruption; Leptin and ghrelin.
