Exploring the Correlation between Insomnia and Iron Deficiency: Implications and Insights

Iron-deficiency Anaemia constitutes a significant public health burden in rural settings, particularly within low- and middleincome countries (LMICs). It is characterized by erythrocyte (red blood cell) deficiency or low haemoglobin concentration; this condition can lead to severe morbidity, especially impacting vulnerable populations like children and pregnant women. Anaemia, manifested by depleted haemoglobin levels, is associated with a variety of clinical presentations including fatigue and asthenia, which can disrupt sleep architecture. Delineating the established association between Anaemia and sleep disturbances has the potential to inform the development of comprehensive interventions aimed at improving overall health outcomes in rural populations. Numerous recent studies examining genome-wide associations have indicated that there may be genetic similarities between Anaemia and Insomnia. So, an increased risk of insomnia in adults was found to be substantially correlated with Anaemia.
