I know someone with very light blue eyes that is very sensitive to light, especially in the morning, after waking up. How can this person have a healthy waking up light seeking routine and how can I encourage him to get to that?

Help him ease into morning daylight rather than forcing a sudden, uncomfortable exposure; keep the routine comfortable and repeatable.

• 1. Start dim and warm: Use gentle, low-level indoor light just after waking, then increase brightness as he feels comfortable. The available guidance supports avoiding light that feels painful, but does not specifically recommend warm-colored light as a morning step. 1
• 2. Introduce daylight gently: Open curtains or blinds in stages, or step outside and look toward the daylight without staring at the sun. He can look slightly away from the sun, and should stop short of painful brightness. Red lighting is discussed as a lower-impact option for evening light, not as a substitute for morning daylight. 2 3
• 3. Explain the purpose and make it easy: Morning light helps signal wakefulness and time the body’s daily rhythms; regular exposure is also associated with better daytime alertness and easier sleep later. Help him set up an easy route outdoors or adjust the blinds so daylight is convenient to get. 4 5
• 4. Keep it gradual and consistent: Any ambient daylight in the first hour after waking can help; the routine need not be perfect every day. The body’s clock integrates light exposure across multiple days, so encourage patience and small, sustainable adjustments rather than pressure. 6 7
