Is Bedroom Temperature worth prioritizing?

Sleep onset and maintenance are physiologically coupled to a decline in core body temperature and a rise in distal (hand/foot) skin temperature, a mechanism laid out in detail across several reviews of sleep thermoregulation and linked to insomnia, restless legs syndrome, and other sleep disorders when disrupted. Weighing that against the numbers, Bedroom Temperature is not a priority based on current data — the evidence is only emerging (38/100), and its estimated impact (30/100) is on the lower end too.
