Question: what is the ideal temperature for sleeping in celsius?
Answer: Your body heat peaks in the evening and then drops to its lowest levels when you're asleep, so a cool 16-18°C (60-65°F) is thought to be an ideal temperature in a bedroom. Temperatures over 24°C (71°F) are likely to cause restlessness, while a cold room of about 12°C (53°F) will make it difficult to drop off.
