Good sleep is not only about hours. It relies on three key components: length, depth, and consistency.
Length means getting sufficient complete sleep. “For many adults, that is normally 7–9 hours per evening. Sleeping considerably lower than this may progressively construct sleep debt and have an effect on long-term well being, even should you really feel purposeful the subsequent day,” mentioned Dr Makhija.
Depth pertains to sleep high quality, particularly if the physique is getting sufficient deep sleep and REM sleep, that are very important levels within the sleep cycle. “Deep sleep aids bodily restore, immune function, and hormone regulation.
