Study Links 'Poor Sleeper' Gene to Lifetime Insomnia, Reveals Potential Reversibility of DNA Methylation Changes for Heart Health and Brain Aging Prevention

A new study suggests that a 'poor sleeper' gene could predispose individuals to a lifetime of insomnia. Researchers are exploring the link between sleep quality and aging, focusing on DNA methylation changes and their potential reversibility to enhance life and healthspan. Another study indicates that daily exercise may counteract a sedentary lifestyle, while napping and brief intense activity are also associated with heart health and brain aging prevention.
