Understanding Sleep and Sleep Cycles
High school students need about 8-10 hours of sleep per night to function optimally. 😴 Sleep cycles are stages your brain goes through during sleep, including REM (rapid eye movement) and non-REM sleep. Each cycle lasts about 90 minutes, with REM being crucial for cognitive functions like memory and learning. 🧠
Knowing your sleep cycles helps you understand why consistent sleep is important. Aim for 4-6 cycles per night, which equals about 6-9 hours of sleep. This foundational knowledge sets the stage for developing good sleep habits. 🛌
