Circadian rhythms are the internal biological clocks of our bodies that regulate various processes such as sleep, body temperature, metabolism, and more. Circadian rhythms can also impact mood and mental health.

Research indicates* that disruptions to these rhythms can lead to various diseases and health problems, such as:нарушение сна

• Sleep disorders
• Weight gain
• Reduced immunity

Light, especially its spectrum, is one of the main factors influencing circadian rhythms. When the photoreceptors in our eyes detect sunlight, our brain receives a signal that it is morning and time to wake up. Exposure to light in the morning hours helps suppress melatonin* production and stimulates wakefulness and activity. In darkness, our bodies begin to prepare for sleep.

Smart lights can automatically mimic the changes in brightness and color temperature of natural light throughout the day. For example, they can emulate morning sunlight with high brightness and cooler color temperature, helping to stimulate wakefulness and suppress melatonin production, and automatically switch to warmer and dimmer light in the evening, promoting relaxation and preparation for sleep.

Smart lights can integrate with other smart devices such as fitness trackers or smart sensors to automatically adjust lighting based on a person’s activity level. For example, they can increase the brightness of the light during the day if decreased activity is detected to maintain alertness.

Smart lights can be set to operate on a specific schedule, helping to establish regular lighting cycles throughout the day and night. This helps stabilize circadian rhythms and improve sleep quality.
