Understanding Circadian Rhythms

The human circadian rhythm typically spans about 24 hours, although some individuals may have rhythms ranging from 24.1 to 25 hours. These internal clocks help regulate sleep and wakefulness, aligning with the external day-night cycle. When there's a disruption, such as during travel or significant lifestyle changes like having a baby, these rhythms can become out of sync, leading to feelings similar to jet lag. The misalignment can then negatively impact cognitive functions, memory, and overall health.
