Biomedical researcher Marta González-Freire emphasizes the importance of protecting the sleep phase occurring between 10 PM and midnight. She explains that consistently going to bed after midnight results in missing this crucial restorative period. González-Freire, holding degrees in Exercise Science, Physiology, and Genetics, currently investigates the biological mechanisms behind aging at the Instituto de Investigación Sanitaria de las Illes Balears (IdISBa). Her research focuses on understanding *why* we age, with sleep being a key component. Disrupting the natural sleep cycle, particularly by delaying bedtime, can negatively affect health and potentially accelerate the aging process. Further study is being conducted to elaborate on these impacts and promote optimal sleep habits. González-Freire's expertise bridges exercise physiology with cellular and genetic biology, giving a holistic approach to aging.
