Specifically, the 80/20 rule suggests that 80% of your sleep quality is determined by 20% of your sleep habits. For example, the following sleep habits are considered the most important for good sleep quality:
Consistent sleep schedule: Going to bed and waking up at the same time every day, including weekends.
Sleep environment: Creating a comfortable sleep environment that is cool, dark, and quiet.
Relaxation before bed: Winding down before bed with relaxing activities, such as reading, meditation, or taking a warm bath.
Avoiding stimulants: Avoiding caffeine, nicotine, and alcohol in the hours leading up to bedtime.
Limiting screen time: Avoiding screens, such as phones, tablets, and TVs, for at least an hour before bedtime.
