Temperature plays a crucial role in our sleep quality. Research suggests that a cooler room temperature between 60-67°F (15-19°C) creates the most conducive environment for optimal sleep. When it's too hot or too cold, it disrupts our natural sleep cycle and can cause restlessness, frequent awakenings, and difficulty falling asleep. The body's core temperature naturally drops during sleep, and a cooler room aids this process. Additionally, cooler temperatures help regulate melatonin production, the hormone responsible for inducing sleep. On the other hand, excessively warm temperatures can lead to sweating, dehydration, and discomfort, making it harder to fall and stay asleep. It's important to find the right balance and adjust room temperature according to personal comfort preferences to create an ideal sleep environment.
