Southern Cross Healthy Sleep Advice

The ideal sleep temperature recommended by health experts, including Southern Cross, is between 15°C and 19°C . This slightly cool environment helps your core body temperature naturally drop as you sleep, which promotes deeper, more restorative rest.

The Science of Cooler Sleep

While every individual has a unique “sweet spot,” most experts suggest keeping your bedroom thermostat set around 18°C for the best nighttime sleep.

• Circadian Rhythm: Your body’s internal temperature drops significantly during the night. If your bedroom is too warm, your body has to work harder to shed heat, which can pull you out of deep sleep cycles and into light, restless sleep.
• Ventilation: A well-ventilated room also ensures that your skin temperature stays comfortable without requiring you to sit in cold drafts.

“Somewhere between 17-19 degrees celsius is ideal”.
