Want to feel younger than you are? Improve your sleep

Not getting enough sleep may cause you to feel older than you really are, according to recent studies. Sleep plays a causal role in how old individuals feel, researchers found. Health and mobility issues can also contribute to feeling older, but lack of sleep was a key factor. Insufficient sleep induces sleepiness, which reduces energy levels and motivation, limiting physical and social activity. Feeling younger has been associated with living longer, lower rates of dementia, less depression, and better overall health. Adequate sleep is essential for maintaining a youthful subjective age.
