Sleep, a vital contributor to cognitive function and memory consolidation, holds the key to unlocking successful learning experiences but is often overlooked in the hustle and bustle of preparations to go back to school.

Research published in the Journal of Clinical Sleep Medicine has illuminated the strong link between sleep — not just the quality, but the timing — and enhanced memory retention, cognitive performance, and overall learning capacity. 

As students embark on a new academic year, prioritizing sufficient and restorative sleep should be at the forefront of their back-to-school checklist.

“Sleep helps you process your experiences from the day. It helps filter out irrelevant details and solidifies important concepts, ensuring that students are better equipped to grasp complex subjects and perform well in their studies,” explains Lana Walsh, sleep and insomnia expert.

Sleep is not just a mere state of rest; it’s a complex process that plays a critical role in memory consolidation. During sleep, the brain engages in a range of activities that optimize learning, including information sorting, memory strengthening, and emotional processing. Proper sleep allows the brain to organize and store new information acquired throughout the day, making it readily accessible for future recall and application.

“Research has shown that learning abilities decline by as much as 40 per cent when students aren’t getting enough regular sleep,” Walsh said.

In today’s fast-paced world, sleep is often compromised for students due to a multitude of distractions and responsibilities. Late-night study sessions, screen time, part-time jobs, and irregular sleep patterns can lead to sleep deprivation, which has been linked to impaired cognitive function, reduced attention span, and decreased ability to retain information.

Tips for quality sleep and better cognitive function

Parents and students are encouraged to create a sleep-friendly environment that supports healthy sleep habits. Tips for promoting quality sleep include:

  • Regular Exercise: Engaging in 30 minutes of physical activity every other day improves sleep latency (time to go to sleep) and quality.
  • Consistent sleep schedule: Encourage students to establish a regular sleep schedule by going to bed and waking up at the same time every day, even on weekends.
  • Technology detox: Limit screen time before bedtime, as the blue light emitted by devices can interfere with the body’s natural sleep-wake cycle.
  • Create a relaxing bedtime routine: Engage in calming activities before bed, such as reading, listening to soothing music, or practicing relaxation techniques like meditation.
  • Optimize sleep environment: Ensure that the sleeping area is comfortable, cool, dark, and quiet, promoting uninterrupted rest.
  • Balanced lifestyle: Encourage a healthy balance of physical activity, a nutritious diet, and stress-reduction techniques to further support quality sleep.

As students gear up for the new school year, it’s essential to recognize that a well-rested mind is a receptive and efficient one.
