🛏️ Your bedroom has its own little climate.
When we think about temperature and sleep, most of us think about the thermostat.
But there are actually several layers to consider:
🌡️ Room temperature — the air around you
🛏️ Sleep-surface temperature — your mattress, sheets, blankets and everything immediately surrounding your body
🔥 Core body temperature — which naturally follows a circadian rhythm and declines as we prepare for sleep
These interact.
Your bedding and mattress create a small microclimate around your body, and the materials, construction and airflow can influence how heat and moisture move away from you. This is one reason two people can sleep in the exact same bedroom and have completely different experiences of temperature.
Here are some tips to keep you cool and comfortable:
✔️ A comfortably cool bedroom
✔️ Good airflow
✔️ Bedding, sleepwear and a mattress that don't trap excessive heat
✔️ Enough—but not too much—covering
✔️ Paying attention to other factors in your environment that may influence sleep - eg. noise, light
Because good sleep isn't about following one perfect formula.
It's about creating an environment that supports what your body is already trying to do.
