When a newborn arrives, every parent wants to ensure their little one is healthy, comfortable, and safe. Sometimes, however, babies are born with a common condition known as neonatal jaundice. This condition gives their skin and eyes a yellowish tint due to high levels of bilirubin in the blood. While it can be alarming to see, it’s usually not dangerous if treated properly. One of the most common and effective treatments for jaundice in newborns is phototherapy.
But many parents ask the big question: Is phototherapy safe for newborn babies? Let’s break it down in detail.
What Is Phototherapy?
Phototherapy is a medical treatment that uses special blue or white light to reduce bilirubin levels in a baby’s blood. The light helps break down bilirubin in the skin so the body can process and eliminate it more easily through urine and stool.
How It Works:
- The baby is placed under a phototherapy lamp or on a special phototherapy blanket.
- The eyes are covered with protective shields to prevent damage from the light.
- The baby’s skin absorbs the light, which changes bilirubin into a form that can be excreted naturally.
Phototherapy has been used safely for decades and is considered the gold standard for treating newborn jaundice.
Why Do Newborns Need Phototherapy?
Most babies have some degree of jaundice in their first week of life. This is because their immature liver is not yet efficient at removing bilirubin.
Phototherapy is recommended when:
- Bilirubin levels are higher than normal.
- There is a risk of bilirubin crossing into the brain, causing kernicterus (a rare but serious complication).
- The baby is premature or has other health conditions.
By lowering bilirubin levels, phototherapy prevents complications and keeps the baby healthy.
Is Phototherapy Safe for Newborn Babies?
The short answer is yes—phototherapy is generally very safe for newborns when used under medical supervision. It is a non-invasive, painless treatment and has helped millions of babies worldwide.
Safety Features of Phototherapy:
- Non-invasive: No needles or drugs involved.
- Controlled exposure: Babies are monitored closely in the hospital.
- Protective measures: Eye shields prevent light damage to the eyes.
- Quick results: Most babies respond within 24–48 hours.
Possible Side Effects of Phototherapy
While phototherapy is safe, like any treatment, it may have mild and temporary side effects. Parents should be aware of these:
- Skin changes
- Some babies may develop a mild rash or dryness.
- The skin may appear bronzed (bronze baby syndrome), but this goes away after treatment.
- Dehydration
- Phototherapy can increase fluid loss, so babies need adequate feeding during treatment.
- Phototherapy can increase fluid loss, so babies need adequate feeding during treatment.
- Eye irritation
- If eye shields are not properly placed, there’s a small risk of irritation.
- If eye shields are not properly placed, there’s a small risk of irritation.
- Interruption of bonding
- Since babies spend time under the light, skin-to-skin contact may be reduced.
These side effects are usually temporary and resolve after therapy ends.
How Long Does Phototherapy Last?
The duration of phototherapy depends on bilirubin levels and the baby’s overall health.
- Mild jaundice: May require only 12–24 hours.
- Moderate to severe jaundice: May need 2–3 days of continuous therapy.
- Very high bilirubin levels: Sometimes require intensive phototherapy or additional treatments such as exchange transfusion (rare).
Doctors monitor bilirubin levels with regular blood tests to decide when therapy can be stopped.
How to Care for a Baby Undergoing Phototherapy
Parents often feel anxious about leaving their baby under the lights. Here are some tips to ensure comfort and safety:
- Keep up with feeding – Breastfeed or formula feed frequently to prevent dehydration and help flush out bilirubin.
- Monitor diapers – Frequent urination and bowel movements are signs that the bilirubin is leaving the body.
- Stay close – Parents can visit often, soothe the baby, and provide comfort between therapy sessions.
- Check skin – Watch for any rashes or dryness and inform the healthcare team.
- Don’t worry about sleep patterns – Babies may sleep more under phototherapy; this is normal.
When to Seek Medical Help
Even after phototherapy, some babies may need further monitoring. Parents should contact a doctor if:
- The baby’s skin looks increasingly yellow.
- Feeding becomes difficult or the baby is excessively sleepy.
- The baby has fewer wet diapers or bowel movements.
- There are signs of dehydration (dry mouth, sunken eyes, lethargy).
Alternatives to Phototherapy
In most cases, phototherapy alone works well. However, if bilirubin levels are dangerously high or do not improve, doctors may suggest:
- Exchange transfusion: Replacing some of the baby’s blood with donor blood to quickly lower bilirubin.
- Intravenous immunoglobulin (IVIg): Used if jaundice is due to blood group incompatibility.
- Enhanced feeding support: Sometimes, simply ensuring proper feeding can help mild cases.
Benefits of Phototherapy
- Proven effectiveness for jaundice.
- Quick improvement in bilirubin levels.
- Reduces the risk of kernicterus and brain damage.
- Safe, simple, and widely available.
Conclusion
So, is phototherapy safe for newborn babies? Absolutely. It is one of the safest, most effective, and most widely used treatments for neonatal jaundice. While mild side effects like skin changes or dehydration can occur, these are temporary and easily managed.
As a parent, seeing your baby under bright lights can be overwhelming, but remember that phototherapy prevents serious complications and helps your baby recover quickly. With proper care, monitoring, and feeding, your newborn will be back to their healthy, glowing self in no time.

Frequently Asked Questions (FAQs)
1. Is phototherapy painful for newborns?
No. Phototherapy is painless. Babies may be fussy due to being unclothed, but the treatment itself doesn’t hurt.
2. Can I breastfeed my baby during phototherapy?
Yes! In fact, frequent breastfeeding is encouraged to help flush out bilirubin.
3. Are there any long-term side effects of phototherapy?
No. Phototherapy is safe and does not cause long-term problems in babies.
4. Will my baby need phototherapy again?
In most cases, no. Once bilirubin levels normalize, they usually stay stable. Rarely, jaundice can return, but this is uncommon.
5. Can phototherapy be done at home?
In some cases, yes. Home phototherapy units are available under strict medical supervision, especially for mild jaundice.
