We lose an hour every spring and gain one in the fall, but our biology doesn’t change as quickly as the clock. In this episode, Sarah and Crystal explore how daylight saving time affects circadian rhythms, hormonal timing, mood regulation, and cognitive performance. They discuss why even a one-hour shift can disrupt sleep architecture, increase irritability and fatigue, and temporarily affect decision-making and emotional regulation.

The conversation also touches on sleep disorders discussed in the DSM-5-TR, including insomnia, sleep apnea, circadian rhythm sleep-wake disorders, hypersomnolence, and narcolepsy, while clarifying how these conditions actually present compared to common media portrayals.

The episode closes with practical, research-based strategies that may help the body adjust more smoothly to time changes, including light exposure timing, consistent sleep routines, and behavioral strategies that support circadian stability.
