Free everyday life tip: Cool the room to 18 °C (step 4 of 11 from "Sleep Better Tonight Without Supplements").
Your body temperature needs to drop by about 1 °C to initiate sleep. A cool room helps this happen faster. Set your thermostat to 18 °C (65 °F) or open a window if the outside temperature is lower. If you do not have air conditioning, a fan pointed at the bed creates airflow that helps your body shed heat.
Sleeping in a warm room (above 22 °C) does not just make you uncomfortable — it measurably reduces deep sleep and increases nighttime wake-ups. If your partner prefers warmth, compromise: cool room, warm blankets. You can always add a layer, but you cannot cool a hot room with willpower. A fan, a cracked window, or a lower thermostat setting costs less than a supplement subscription.
Pro tip: If you tend to overheat, try sleeping with one foot outside the blanket. Your feet are efficient heat radiators and this small trick drops your perceived temperature noticeably.
