Yahoo Health • • health
Key Points:
- Morning light exposure is crucial for regulating the body's circadian clock, helping people feel more awake during the day and sleep better at night, with outdoor light providing significantly higher brightness than indoor lighting.
- Experts recommend getting morning light within an hour of waking, ideally for 30 minutes to an hour, either by going outside or sitting close to and facing a bright window to maximize light exposure to the eyes.
- If natural light is unavailable, using a bright indoor lamp of at least 3,000 lumens or a light-therapy box can be effective alternatives to simulate morning light and support circadian rhythms.
- Consistency in timing and duration of morning light exposure is important for resetting the body clock, and benefits may take a few weeks to become noticeable in sleep patterns.
- To enhance sleep quality, it is also advised to dim lights about two hours before bedtime, creating a strong contrast between bright mornings and dark evenings to optimize circadian rhythm alignment.
