🎯 Learning Objectives
By the end of this lesson, learners will be able to:
✅ Understand how sunlight affects jaundice
✅ Learn safe timing, position, and precautions for sun exposure
✅ Know the risks and limits of using sunlight as treatment
☀️ Why Use Sunlight?
Sunlight contains blue light (wavelength 460–490 nm), which helps break down bilirubin in the baby’s skin — similar to hospital phototherapy. In settings where hospitals or phototherapy devices are unavailable, controlled sunlight exposure can help reduce mild jaundice.
✅ Safe Sunlight Use: The Right Way
| Element | Safe Practice |
|---|---|
| Timing | Expose baby between 7:30 am and 9:30 am or 4:30 pm to 5:30 pm (cool sunlight) |
| Duration | 5–10 minutes per session, 2–3 times per day |
| Position | Undress baby to diaper or nappy; expose chest and legs while covering eyes |
| Surface | Place baby on a clean, flat surface (bed, mat, mother’s lap) near a window or outside in shade |
| Eye Protection | Cover baby’s eyes gently with a clean cloth or small hat to prevent damage |
| Supervision | Always supervise closely — never leave baby alone in the sun! |
⚠️ Dangers of Improper Sun Exposure
| Risk | What Happens |
|---|---|
| Overheating / Dehydration | Baby may become too hot, sweat excessively, or stop feeding |
| Sunburn | Delicate newborn skin can burn quickly, especially in harsh sunlight |
| Eye Damage | Bright UV rays can harm baby’s retina if eyes are not protected |
| Insect Exposure | Outdoor sunning without nets or covers may expose baby to mosquito bites |
🔴 Avoid midday sun (10 am to 4 pm) – too harsh for newborn skin.
🔴 Never leave baby in a closed car or under direct glass for sun exposure.
🚫 Common Myths vs. Truths
| Myth | Truth |
|---|---|
| “Sunlight is enough — no need for hospital.” | Mild jaundice may improve, but moderate to severe jaundice needs phototherapy or transfusion. |
| “More sun = better.” | Too much sun can burn or harm your baby. Use moderate, supervised exposure only. |
| “Cover baby with palm oil first.” | This may overheat the skin or block light. It’s not recommended. |
🌍 Real-Life African Example
In northern Nigeria, a mother noticed yellow eyes on Day 3. The CHW advised gentle morning sun and breastfeeding while arranging for a bilirubin test. Early intervention meant no hospital stay was needed.
🍼 Breastfeeding + Sunlight = Best Combo
-
Sunlight helps the skin
-
Breastfeeding helps the liver and gut
-
Together, they help the baby clear bilirubin naturally
💧Caution: No glucose water or herbs—just frequent breastmilk feeds!
🧠 Key Messages for CHWs & Parents:
-
Use sunlight only as a temporary aid — not a replacement for medical care
-
Never expose babies under harsh sun or for long periods
-
Always combine with early medical testing or CHW check-up
