Why Deep Sleep Matters More Than Hours Slept

We often fixate on the number 8—eight hours of sleep, the so-called gold standard. But quality trumps quantity every time. If you’re waking up groggy after 9 hours in bed, you might be missing out on deep, restorative NREM Stage 3 sleep.

What is Deep Sleep?

Deep sleep, or slow-wave sleep, is the stage where your body does its heavy lifting. It's when your brain cleanses itself of toxins, your muscles repair and grow, and your immune system strengthens. During this phase, your heart rate and breathing slow to their lowest levels.

Signs You're Not Getting Enough

• Feeling groggy upon waking (sleep inertia)
• Craving high-calorie foods
• Frequent illness
• Difficulty consolidating memories

How to Optimize Deep Sleep

1. Cool Down Your Room

Your body temperature needs to drop to initiate deep sleep. Aim for a bedroom temperature between 60-67°F (15-19°C).

2. The Right Mattress Matters

Pressure points can pull you out of deep sleep into lighter stages. A mattress that properly contours to your body, like our Hybrid Collection, ensures uninterrupted rest.

3. Consistent Timing

Going to bed at the same time every night regulates your circadian rhythm, helping your body anticipate sleep and transition through cycles more efficiently.

"Sleep is the single most effective thing we can do to reset our brain and body health each day."

Prioritizing deep sleep isn't just about feeling rested—it's about long-term health. Start with small changes tonight, and your body will thank you tomorrow.
