If you wake up sweating or constantly kick off the covers, you're a hot sleeper. The good news: temperature is one of the most evidence-backed factors for sleep quality, and there are proven solutions.
Your body temperature naturally drops 1-2°F as you fall asleep. This decline is a signal to your circadian rhythm that it's time for rest. When your environment is too warm, this natural process is disrupted.
Unlike many sleep interventions, temperature control has consistent, replicable research backing. This makes cooling products some of the most reliable investments for sleep improvement.
We recommend this order based on effectiveness and cost-efficiency:
Set AC to 65-68°F. This is free (beyond energy costs) and the most effective intervention.
Water-cooled systems like Eight Sleep offer precise temperature control at the body level.
Phase-change materials and gel-infused foams can help, though less effective than active cooling.
Linen or bamboo sheets, lightweight blankets. Simple but meaningful improvements.
Loose, breathable clothing. Avoid heavy meals and alcohol before bed (they raise body temp).

Counterintuitively, warming your skin causes blood vessel dilation, which actually helps your core cool down faster.
Your feet and hands are temperature regulators. Exposing them helps dump excess heat efficiently.
Alcohol disrupts thermoregulation and causes night sweats. Limit intake 3+ hours before sleep.
Moving air increases evaporative cooling from your skin. A ceiling or standing fan can help significantly.
