How to Treat Normal Headaches — and Catch the Red Flag Ones Before It’s Too Late

We’ve all had headaches. Sometimes they come after a long, hot day or when we haven’t had enough water or sleep. Most of the time, they go away with rest, a glass of water, or a painkiller. But some headaches can be a sign of something more serious. Knowing when to worry can make a big difference, and that’s where the SNOOPP rule helps.

What Makes a Headache a Red Flag?

A red flag headache means your pain might be caused by another health problem in your body—something beyond stress or dehydration. These are called secondary headaches. The SNOOPP trick helps us remember the warning signs to watch out for. Each letter stands for something that might mean the headache isn’t ordinary.

(S) Systemic Signs and Symptoms

If you have a headache along with other body problems like fever, chills, weight loss, or muscle pain, it’s time to take note. These signs can happen when your body is fighting something more serious, like an infection, cancer, or problems with blood vessels. For example, infections such as meningitis or inflammation in the brain can start with a headache that feels different from the usual kind.

(N) Neurologic Symptoms

If your headache comes with numbness, weakness, confusion, or changes in vision, it could point to a problem in your brain or nerves. Sometimes people feel dizzy, find it hard to talk, or even notice their face drooping on one side. These are signs that should never be ignored. They could mean a stroke, tumor, or another brain condition.

(O) Onset, How It Starts

Did your headache come on slowly, or did it hit suddenly like a thunderclap? A sudden, sharp headache that reaches its peak in seconds can be dangerous. It might be linked to bleeding in the brain, known as a hemorrhage. This kind of headache feels different, it’s often described as the “worst pain ever.” If you experience that, you need to get medical help immediately.

(O) Older Age or New Kind of Pain

If you’re over 50 and suddenly start getting headaches you’ve never had before, it’s not something to brush off. It could be linked to conditions like giant cell arteritis or even eye problems such as glaucoma. Also, if your regular headaches have changed—maybe they’re stronger or feel different—that’s another reason to be alert.

(P) Progressive Headaches

A headache that keeps getting worse or lasts longer than usual can be a warning sign. If it feels like each day the pain grows or spreads, it’s time to pay attention. These changes can show that something is putting extra pressure inside your head, and the cause needs to be checked.

(P) Position, Pressure, and Papilledema

Sometimes your headache changes when you stand, bend, or lie down. This could mean changes in the pressure inside your skull. Sneezing, coughing, or straining might make it worse. These kinds of headaches can happen if there’s a leak or too much fluid in your brain. Another sign to watch for is blurred vision or eye pain, which may come from swelling at the back of your eye, a condition called papilledema.

How to Prevent Common Headaches

Most headaches, especially during hot weather, come from simple things like dehydration, tiredness, or heat exposure. Here’s how to keep them away:

Drink lots of water throughout the day, your body needs it more than you think. Avoid too much caffeine or alcohol, since they can dry you out. Try to stay in cool places and wear sunglasses to protect your eyes from glare. Don’t forget to rest and sleep properly, your brain needs a break just as much as your body does.

Most headaches aren’t dangerous, but some need extra care and quick action. If your headache feels unusual, stronger, or comes with other strange symptoms, don’t ignore it. Your body might be trying to tell you something important.
