Deep sleep topic Deep sleep is the stage when the human body sleeps the deepest and most soundly. At this time, you cannot hear any noise outside and it is difficult to be awakened by others. When you wake up, you will feel refreshed. At this moment, hormones in the human body are being secreted in large quantities, immune cells and various damaged cells (especially brain cells) are repairing, fatigue is recovering, energy is being stored, the digestive system is busy absorbing nutrients, and waste is being excreted in large quantities. Deep sleep is the guarantee for children to grow taller and develop their intelligence; for young people to be energetic; for middle-aged people to be strong; and for the elderly to be healthy and live longer.
