Which strategy is effective for creating a sleep-friendly environment?

Creating a sleep-friendly environment plays a crucial role in achieving quality rest, and maintaining a dark and cool bedroom is particularly effective for this purpose. Darkness stimulates the production of melatonin, a hormone that helps to regulate sleep-wake cycles. When the room is dark, it signals to your body that it's time to wind down and prepare for sleep.

Additionally, a cooler room temperature is conducive to sleep because the body's internal temperature naturally drops during sleep. A cooler environment helps facilitate this natural cooling process, which can enhance comfort and promote deeper sleep.

This combination of darkness and a cooler temperature is widely supported by sleep research, indicating that both factors significantly improve the quality of sleep, making it easier to fall asleep and stay asleep throughout the night.
