Ano ba ang Evil Eye? Understanding ‘Usog’ and How Filipinos Protect Themselves
From Manila to Singapore, the ‘usog’ or ‘bati’ belief travels with us. Here’s what it actually is, what the traditional protections are, and — just as important — when the symptoms need a doctor, not a prayer.

Every Filipino has heard it at least once. *"Baka nausog ka"* from lola when you suddenly get chills. *"Puwera usog"* whispered by a tita the moment she sees your newborn. A cousin pulling a baby back from a crowded market because *"baka may bati"*. For many Filipino families, the fear of the evil eye isn’t a cartoon superstition — it’s a quiet, everyday habit that gets passed down without anyone needing to explain it.
This is a plain-language primer. What *usog* and *bati* are, where the belief comes from, what the traditional protections look like, and — the part most *titas* won’t tell you — when the "evil eye" is actually something a doctor needs to look at.
Ano nga ba ang evil eye?
In Filipino folk belief, the *evil eye* — called usog, bati, or in some regions mata — is the idea that a person with a "strong look" or sudden admiration can transfer illness or discomfort to another person, especially a baby, a pregnant woman, or sometimes even an adult. It doesn’t have to be malicious. In most Filipino accounts, the person casting usog doesn’t even mean to — it’s their energy, their stare, or a stranger’s burst of affection toward a cute baby that supposedly does it.
The belief isn’t uniquely Filipino. You’ll find cousins of it across Mediterranean, Middle Eastern, Latin American, and South Asian cultures — *mal de ojo* in Mexico, *nazar* in Turkey and India, *mati* in Greece. Wherever it appears, the core idea is the same: certain kinds of looking or attention can carry weight.
Kailan siya tumatama
Here’s the classic setup every Filipino family has seen:
A stranger or relative looks at a baby, says *"Ang cute naman ng bata,"* and leaves.
Hours later, the baby is fussy, colicky, running a low fever, or won’t feed.
A tita or lola takes one look and says: *"May bati."*
Older children and adults can get usog too, traditionally showing up as:
Sudden stomach pain or cramps
Chills, fatigue, or an unexplained low fever
Vomiting after a new encounter
General malaise that came on "out of nowhere"
In traditional belief, the giveaway is timing. The symptoms start shortly after contact with a specific person — the *nagka-bati* — and they’re said to clear up once the "eye" is lifted.
Paano nga ba mag-protect
If you grew up Filipino, you’ve seen these:
"Pwera usog" said out loud (or under the breath) when a stranger praises a baby. It’s not a curse on the stranger — it’s a verbal shield.
Finger-cross on the forehead with saliva. The person who (maybe) gave usog wets their finger and makes a small cross on the baby’s forehead. It sounds odd to outsiders; for many Filipinos, it’s just what you do.
A red string or beaded bracelet on the baby, sometimes with a small religious medal or *anting-anting*, meant to ward off negative energy.
The sign of the cross before leaving the house or entering a crowd, especially with a baby or a pregnant woman.
Herbs and smoke rituals — *tawas* (alum), dried herbs, or blessed oil from certain provinces. In some families, a *manghihilot* is called if the symptoms don’t pass.
Avoiding crowded wet markets or busy malls with very young babies, especially in their first weeks.
These practices are doing something real for the family, even if it’s not what folk belief says it does. They create a deliberate moment of care around a vulnerable child. They mark the transition from outside world to safe home. They give a family a shared ritual when they feel powerless.
What doctors would actually say
Let’s be honest about this part, because it matters.

Most symptoms blamed on *bati* — a fussy baby after a busy day, a low fever, colic, mild stomach upset — have real medical explanations. Overstimulation, teething, gas, an early viral infection, a missed nap, a warm room. Babies especially have a small tolerance for noise, crowds, and irregular feeds; a crowded visit really can leave them cranky without any supernatural mechanism needed.
That doesn’t mean the belief is silly. People have noticed for centuries that babies get unsettled after heavy social exposure — the belief is an *explanation* built around a real pattern. The belief is wrong about the cause but often right that something is going on.
When to stop ritualising and see a doctor
The part no well-meaning tita will ever tell you: if your baby — or any loved one — shows any of these, go to a GP or polyclinic now. Don’t wait for *bati* rituals to "work first."
Red flags that need medical attention:
Fever of 38°C or higher in an infant under 3 months — always, no exceptions.
Fever that doesn’t break within 24–48 hours at any age.
Poor feeding, or refusal of breast or bottle for more than a feeding cycle.
Lethargy — unusually sleepy, hard to wake, floppy.
Fast or laboured breathing, or chest pulling in with each breath.
Persistent vomiting or signs of dehydration (sunken fontanelle, few wet diapers, dry mouth).
A rash that doesn’t fade when pressed, or any rash with fever.
In Singapore you have clear options: a neighbourhood polyclinic for low-cost primary care, the 24-hour children’s emergency at KK Women’s and Children’s Hospital, or any private GP.

Paano ito na-navigate sa Singapore
Two practical notes specific to life here.
Multicultural crowds mean more strangers giving your baby attention. In Singapore you’ll have Chinese aunties cooing, Indian uncles smiling, Western expat neighbours reaching for your baby’s hand. If you grew up with *usog* thinking, this can feel like constant low-grade exposure. Most Filipino parents here land in a practical middle ground: quietly say "pwera usog" to themselves, keep a red bracelet on the baby, and don’t bother explaining the belief to the non-Filipino well-wisher. You get to hold your culture without making it anyone else’s problem.
Trust your instincts, but not over medicine. If an elder in the family insists on ritual before clinic, it’s fine to do both — make the sign of the cross, whisper the prayer, tie the bracelet, *and* take the baby to the doctor anyway. One doesn’t cancel the other. The protective ritual can comfort your family. The doctor treats the cause.
A final note
Belief and medicine aren’t enemies. Filipinos have held onto *usog* for a reason — it reflects a community instinct that children are precious and that the world outside the home is full of things that can affect them. It’s a cultural shield built over generations.
Use the shield. Whisper the words. Tie the red bracelet. And when the fever won’t break or the baby won’t feed, take them to a doctor. That’s not a betrayal of the tradition — it’s what generations of Filipino *nanay* have always done: combine what the heart knows with what the body needs.
