Azizi A. Seixas, the associate director of the Center for Translational Sleep and Circadian Sciences at the University of Miami Miller School of Medicine, said chronic sleep deprivation has long-term consequences for your health, including higher risks of heart disease, Type 2 diabetes, obesity, Alzheimer’s and Parkinson’s disease.

The shift to daylight time causes sleep loss only once a year. But in the short term, he said, individuals can experience “impaired cognitive function,” weakened immune systems and disrupted circadian rhythms.
