Thanks for prompting me on total sleep hours. My original intent was to learn about "dream" sleep. If we classify total sleep hours, there are four stages. A couple of my colleagues work on sleep research to create commercial products for ITC Hotels, and the way I understand sleep from them is summarized below. | Thanks for prompting me on total sleep hours.

REM (dream sleep) is the last stage of sleep. Dreams are not medically useless; they serve several important functions tied to brain health and emotional well-being. However, a longer duration of REM is not ideal (say, >30 minutes), because it would reduce N3 (deep sleep) duration, where tissue repair and immune boosting occur. If the body does not "restore" fully, damage continues and can even lead to internal inflammation. | REM (dream sleep) is the last stage of sleep.

Thanks for prompting me on total sleep hours. My original intent was to learn about "dream" sleep. If we classify total sleep hours, there are four stages. A couple of my colleagues work on sleep research to create commercial products for ITC Hotels, and the way I understand sleep from them is summarized below.
