CNN —Not getting enough sleep may cause you to feel five to 10 years older than you really are, according to two new studies. A lack of energy and motivation can certainly contribute to feeling older while limiting a person’s ability to remain physically and socially active, both of which contribute to feeling young, Balter said. For every night of poor sleep during that time, people reported feeling about a quarter of a year older than their chronological age. “These findings support that sleep, a vital biological phenomenon, might hold the key to feeling young,” Balter and her colleagues wrote in the study. “If you suspect that your sleep deprivation is due to a sleep disorder such as insomnia or sleep apnea, it’s crucial to seek evaluation and treatment from a healthcare professional,” he said.
