A sleep cycle is a series of stages that our body goes through during sleep. Each cycle typically lasts around 90 minutes and includes both REM (rapid eye movement) and non-REM sleep. These cycles repeat throughout the night, with the first cycle typically being shorter and containing less REM sleep than subsequent cycles.

Optimizing your sleep cycle can lead to better rest, improved mood and cognitive function, and a reduced risk of health problems such as obesity, diabetes, and heart disease. It can also help you feel more alert and energized during the day.

There are several ways to optimize your sleep cycle, including:

• Stick to a regular sleep schedule, even on weekends
• Avoid caffeine, alcohol, and nicotine before bedtime
• Create a relaxing bedtime routine
• Keep your bedroom cool, dark, and quiet
• Limit screen time before bed
• Exercise regularly, but not too close to bedtime

The ideal amount of sleep varies depending on age and individual needs, but most adults need 7-9 hours per night. It’s important to listen to your body and get enough sleep to feel rested and alert during the day.

If you’re still having trouble sleeping despite making lifestyle changes, it may be helpful to speak with a healthcare provider. They can rule out any underlying health conditions and provide guidance on other strategies for improving your sleep.
