Ultradian Rhythm

Ultradian rhythms are regular cycles in our body that repeat multiple times a day, typically every 90 to 120 minutes. These rhythms influence processes like sleep stages, hormone release, heart rate, and alertness. For example, during sleep, your body goes through several sleep cycles, each lasting about 90 minutes, switching between different sleep stages. Recognizing these natural cycles can help optimize activities like work, rest, and sleep, as they reflect the body's biological clock working continuously throughout the day.
