Circadian Health Glossary
Dormancy
Dormancy in nature is when plants lay dormant during harsh winters, conserving energy to bloom in spring. Animals hibernate, slowing their metabolic processes only to emerge revitalized. This natural cycle is a blueprint for human behavior, signaling that periods of rest are not just natural but necessary for growth and renewal.
To bring this into the human context, we must understand that periods of rest aren’t simply a lack of activity; they are active and inextricably linked to our cognitive and physical peak. The circadian rhythm, our internal body clock, oscillates between periods of activity and rest, regulating everything from our performance to our emotional well-being. Understanding and honoring these rhythms could hold the key to sustainable high performance and well-being.
Types of Dormancy
There are three distinct types of dormancy:
-
Seed Dormancy prevents seeds from germinating prematurely, ensuring they germinate only when conditions are favorable for seedling survival.
-
Bud Dormancy in plants allows them to survive harsh winters by keeping their buds protected until spring arrives.
-
Diapause is a state of dormancy observed in some insects and invertebrates, triggered by changes in day length or temperature.
Physiological Changes Caused by Dormancy
-
Reduced metabolic rate: This conserves energy and minimizes resource utilization.
-
Changes in hormone levels: Specific hormones may be produced to promote dormancy and inhibit growth processes.
-
Increased stress tolerance: Physiological adaptations may enhance the organism’s ability to withstand harsh conditions.
