The Magic Number: Why 65°F (18°C) is Perfect for Sleep

Home » Sleep Science » Current Article
Your body needs to cool down to shut down. Thermal regulation is tightly linked to circadian rhythms. Studies show that the optimal ambient temperature for sleep is roughly 65°F (18.3°C). Too hot, and you block REM sleep. Too cold, and your body exerts energy to stay warm.

Scientific Verdict

Consistency is key. Whether you are using a new supplement, a breathing technique, or a gear upgrade, you typically need 3 to 7 days to see full results. Your brain needs time to learn the new association between this habit and sleep. Give it a week before you quit.

Final Thoughts

Experimentation is the only way to find what works for your unique biology. Start tonight, track your results in a sleep log, and adjust as needed. Sweet dreams.
