💡 Sleep Optimization Tips
Sleep Cycles
A complete sleep cycle lasts about 90 minutes. Waking up at the end of a cycle helps you feel more refreshed.
Consistency
Try to go to bed and wake up at the same time every day, even on weekends, to regulate your circadian rhythm.
Blue Light
Avoid screens 1-2 hours before bedtime. Blue light can interfere with melatonin production.
Temperature
Keep your bedroom cool (60-67°F / 15-19°C). A cooler environment promotes better sleep quality.
