10 Hours Before Sleep: Avoid Caffeine

The rule suggests avoiding coffee, tea and other caffeinated drinks around 10 hours before bedtime. Caffeine can remain active in the body for several hours and may affect the ability to fall asleep, especially for people who are sensitive to it.

3 Hours Before Sleep: Finish Heavy Meals And Alcohol

The next step recommends avoiding heavy meals and alcohol about three hours before sleeping. Eating too close to bedtime may cause digestive discomfort and disturb sleep quality.

2 Hours Before Sleep: Stop Work

The rule advises ending professional work or mentally stressful activities two hours before going to bed. This gives the brain time to relax and move away from work-related thoughts.

1 Hour Before Sleep: Avoid Screens

The “1” stands for stopping screen usage including smartphones, laptops and tablets about one hour before sleeping. Blue light from screens may interfere with the body’s natural sleep cycle by affecting melatonin production, the hormone responsible for sleep regulation.

Maintaining a fixed sleep schedule, reducing caffeine intake, limiting screen exposure and creating a relaxing bedtime routine are often suggested by sleep experts for improving sleep quality.
