Sleep plays a vital role in keeping the brain and body healthy. As people age, sleep often becomes lighter and more fragmented, which can increase stress, weaken the immune system, and speed up cellular aging. Poor sleep has also been linked to higher levels of inflammation and shorter telomeres, the protective caps on our DNA that shorten as we age. Contemplative practices like meditation can help reduce stress and inflammation and improve sleep, but their effects are often modest, in part because they are practiced while awake. Dream Yoga, a centuries-old Tibetan Buddhist practice, takes a different approach by cultivating awareness during sleep and dreams. In this state, known as lucid dreaming, practitioners can recognize that they are dreaming and work with their experiences in real time. This project will test whether an eight-week Dream Yoga–inspired program can improve biological markers of stress and aging. We will compare it to an active health program in a randomized trial. Participants will use home-based sleep monitors, virtual reality training, and simple finger-prick blood samples to measure changes in inflammation and telomere activity. This innovative study explores whether sleep itself can be transformed into a time for healing, resilience, and healthy aging.
