There’s a bit of a buzz around Jimmy Kimmel’s recent claim that North Americans are sleeping more than ever—a statement that certainly made me raise an eyebrow. From what I’ve observed, and according to the heavyweights in sleep research, the reality is quite the contrary. It appears that Americans are actually getting less sleep than before. Factors such as excessive screen time, constant access to technology, and long work hours are not only cutting into our sleep time but are also degrading the quality of our sleep.
Let’s dive into the insights of my favorite sleep expert, Matt Walker, who is a real authority on the science of sleep. He emphasizes the importance of both REM and non-REM sleep, including deep sleep, for maintaining our health.
Here’s a summary of Walker’s views and his QQRT (Quality, Quantity, Regularity, Timing) framework for sleep improvement:
Quality and Deep Sleep: Deep sleep, a vital non-REM stage, plays a crucial role in memory consolidation, cellular repair, and clearing metabolic waste from the brain. Walker points out that achieving high-quality deep sleep is essential for mood regulation and learning efficiency.
Quantity and REM Sleep: REM sleep is essential for emotional regulation, creativity, and problem-solving. Ensuring sufficient REM sleep is crucial as it supports mental and emotional well-being.
Regularity: Walker stresses the importance of keeping a regular sleep schedule to stabilize your body’s internal clock, which can significantly enhance both the quality and quantity of sleep, especially after sleep-deprived nights.
Timing: It’s advised to avoid drastic changes to your bedtime or waking hours, even after a poor night’s sleep. A consistent wake-up time aids more than extending sleep erratically, which might result in more time spent in lighter sleep stages rather than in deep or REM sleep.
On nights when sleep seems elusive, Walker recommends sticking to your regular schedule and making your bedroom conducive to sleep—think cool, dark, and quiet. Reducing caffeine and minimizing screen time before bed can also help enhance sleep quality and duration.
Furthermore, incorporating daily exercise can significantly benefit your sleep cycle. However, timing is crucial: while a morning jog or an afternoon spin class can improve your sleep, intense workouts close to bedtime might be disruptive.
Alternatively, a calm evening walk or some gentle yoga can help you wind down, setting the stage for a good night’s sleep.
