CHICAGO – Daylight Saving Time begins on Sunday, moving our clocks forward by one hour. This shift can disrupt our sleep patterns because of changes in light exposure. Light plays a big role in when we feel awake or sleepy. With the change, mornings become darker while evenings get brighter, making it harder for some people to fall asleep at their usual time. This can lead to feeling tired and may increase the risk of accidents. To adjust, try to keep a consistent bedtime, and make your bedroom comfortable and dark.
