It always happens at 2 a.m. Someone in the house wakes up hot, achy and miserable, and you realize the thermometer batteries died sometime last winter.
Cold and flu season is the worst time to go shopping for supplies. The smarter move is a small, boring kit you assemble now and forget about until you need it. Here is what is actually worth having.
1. A reliable thermometer
A fever is one of the first things a doctor will ask about, and “I felt warm” is not a number. For adults, a temperature of 100.4°F (38°C) or higher is generally considered a fever.
A forehead or ear thermometer is fast and easy for kids and for checking overnight. Keep spare batteries with it and check that it works before you need it.

2. A fingertip pulse oximeter
A pulse oximeter clips on a fingertip and shows your blood oxygen saturation (SpO2) and pulse rate in seconds. Readings of 95% or higher are typical for healthy people at rest. Persistently low readings, or any reading paired with trouble breathing, are a reason to call a doctor.

3. At-home tests
When symptoms start, knowing what you are dealing with helps you decide whether to stay home, who to tell and when to reach out to a clinician. Keep a couple of rapid tests in the cabinet so you are not hunting for them while sick.

4. A blood pressure monitor, especially if you take cold medicine
Some over-the-counter decongestants can raise blood pressure. If you already manage hypertension, it is worth checking your numbers while you are sick and asking a pharmacist before you pick up a cold remedy.

When to call a doctor
Home devices give you information, not a diagnosis. Their job is to help you describe what is happening clearly and decide on next steps with a professional.
