Understanding Temperature’s Effect on Sleep

1. Regulates Your Sleep Comfort

Temperature plays a key role in how comfortable you feel while sleeping. Your body naturally cools down at night to prepare for rest, dropping by a few degrees. A bedroom that’s too hot or cold can stop this process, making sleep harder. The ideal temperature helps you fall asleep faster and stay asleep longer.

• A bedroom temperature of 16–20°C helps your body cool down, promoting deeper and more restful sleep.
• Extreme temperatures above 24°C can reduce your deep sleep by 15%, making you wake up feeling tired.

2. Impacts Sleep Quality and Health

An unsuitable sleep environment temperature can lower your sleep quality and affect your health. You might wake up often, feel restless, or struggle to reach restorative sleep stages. Over time, this can increase stress and weaken your immune system. Keeping the right temperature supports better sleep and overall wellbeing.

• High temperatures increase wakefulness, leading to fragmented sleep and less time in deep sleep stages.
• Poor sleep from temperature issues raises your risk of stress-related health problems over time.

3. Common Temperature Challenges for Sleep

Various temperature challenges can disrupt your sleep, often without you noticing their impact. Hot summer nights, cold winter bedrooms, or inconsistent heating can cause issues. Even small fluctuations from a thermostat can affect sensitive sleepers. Recognising these challenges helps you create a better sleep environment.

• Hot nights above 26°C disturbs sleep for 25% of people, causing more awakenings and lighter sleep.
• Cold bedrooms below 12°C make it harder to fall asleep, delaying sleep onset by 15 minutes on average.

4. Tips to Optimise Temperature for Better Sleep

You can improve your sleep by managing your bedroom temperature effectively. Set your thermostat to a cool, comfortable range and use breathable bedding to stay relaxed. Dress in light, moisture-wicking sleepwear to avoid overheating at night. These steps help you sleep more deeply and wake up refreshed.

• Setting your bedroom to 18°C can improve sleep quality, helping you feel more rested daily.
• Breathable bedding like cotton reduces overheating, helping you maintain a stable body temperature through the night.
