What is Sleep and Why is it Important?
Sleep is a natural, recurring state of rest that allows the body and mind to repair, restore, and rejuvenate. During sleep, our brain cycles through different stages, including REM (Rapid Eye Movement) and non-REM sleep, each with distinct functions vital for various biological processes.
The Importance of Sleep lies in its ability to help regulate mood, memory, immune function, metabolism, and even cardiovascular health. Without adequate sleep, these systems cannot function optimally, leading to short-term impairments and long-term health complications.

The Science Behind Sleep: Understanding Sleep Cycles
Sleep occurs in cycles, typically lasting 90 minutes, and includes the following stages:

- Stage 2: Heart rate slows, and body temperature drops.
- Stage 3 (Deep Sleep): Critical for physical restoration and immune system function.
- REM Sleep: Involves dreaming and is crucial for cognitive functions like memory and learning.
Each cycle is essential. Skipping or shortening these stages can negatively impact overall well-being.
