World Sleep Day is celebrated every year on the third Friday of March. In 2025, World Sleep Day falls on Friday, March 14.

What is the Importance of Sleep?

Sleep is a vital process during which our body and mind are renewed. Quality sleep strengthens our immune system, supports brain functions, and improves our mood. The main benefits of sleep are:

• Physical Renewal: The process during which muscles, organs, and cells repair themselves.
• Mental Rest: Improves learning, memory, and problem-solving abilities.
• Emotional Balance: Reduces stress levels and improves mood.
• Disease Prevention: Reduces the risk of diabetes, obesity, and heart disease.

Sleep should be in harmony with our body's biological rhythm, the circadian cycle. When this cycle is disrupted, health problems can arise.
