Sleep quality is just as important as the number of hours you sleep. Light, sound, air quality, temperature, and what you eat before bed all affect your sleep quality.

As you fall asleep, your core body temperature naturally drops by 2–3 degrees. Keeping your bedroom between 60–67°F can support this natural cooling process, making it easier to fall asleep and stay in a deep sleep.

Dim the lights 2–3 hours before bed, avoid blue light and LED lights in the evening, and eliminate small light sources in the bedroom. These simple changes can help improve sleep quality.

Snacking before bed can spike blood sugar and contribute to blood sugar fluctuations throughout the night, making it harder to get restorative sleep.

The benefits of deep sleep include better memory, improved brain waste removal, increased growth hormone, stronger immune function, and more stable blood sugar, all of which can help you stop waking up feeling tired.
