What is the Importance of Sleep?

Sleep is a vital process during which our bodies and minds are renewed. Quality sleep strengthens our immune system, supports brain functions, and improves our mood. The primary benefits of sleep are as follows:

• Physical Renewal: It is the process during which muscles, organs, and cells repair themselves.
• Mental Rest: It improves learning, memory, and problem-solving abilities.
