Understanding Sleep Quality and Quantity
Quality sleep requires a balance of both quantity and specific characteristics such as timing and intensity. Duration is straightforward, generally measured by how many hours a person sleeps, but simply achieving a specific duration doesn't guarantee quality. It is crucial for individuals to consider their sleep timing, as the body's natural circadian rhythms dictate optimal periods for restorative sleep. Achieving good quality sleep also means that it's essential to have sufficient uninterrupted sleep and not wake frequently, as frequent awakenings can affect overall restfulness.
