Many people return to the gym, a run, or a long day of yard work within a few days of a bump to the head. Some feel fine. Others notice that their head throbs halfway through a set, or that the room suddenly feels too warm. This piece offers a plain way to keep track of what your body did and how it responded, so you have something concrete to bring to a visit in the St. Louis metro this week.

This is educational information, not a diagnosis. Only a licensed clinician who examines you can tell you what your symptoms mean and whether it is safe to train. What follows is a log you can keep on paper or in a notes app.

Why exercise is worth noting

Effort changes how a head feels. Heavy lifting, hard cardio, and heat can each shift pressure, pulse, and focus in ways that are easy to forget by evening. When a headache or fog shows up after activity, the timing matters. A note that says the headache began during the second mile is far more useful than a general sense that your head hurt last week.

What to write down each day

Start a new line for each day you move your body on purpose. Include the date and the time you started. Then write the kind of activity, such as a walk, a stationary bike, a weight session, or a game of pickup basketball. Keep the description short and factual.

Next, note how hard it felt on a scale you choose and use every day. Pick one scale, such as one to ten, and stick with it. Write the number you felt at the start, at the midpoint, and at the end. Do not round up or down to make the day look better.

Then add what changed. Write whether your head felt heavier, hotter, tighter, or foggy. Note whether light or noise bothered you more than usual, whether you felt nauseous, and whether your balance felt off when you turned quickly. Record the time each symptom started and the time it eased, if it did.

Heat, breath, and hydration

Workouts in summer heat, hot yoga rooms, and crowded gyms can raise body temperature quickly. Note the setting. Was the room hot? Was it crowded? Did you drink water before, during, and after? Did you skip a meal? These details help a clinician see patterns that a single symptom would hide.

Also note your breathing. Did you hold your breath during lifts? Did you feel lightheaded when you stood up after a set? Lightheadedness after standing deserves its own line, because it can point to a different cause than a headache does.

Walks, stairs, and short bursts

Not every day of movement is a big session. A brisk walk, a flight of stairs, or a few quick sprints to catch a bus can also leave a mark. Log them just as carefully. Short, sharp efforts are easy to dismiss, yet they often produce the same pressure or fog as a longer workout.

Bring the log to your visit

Before you go, count the days you logged and look for patterns. Did symptoms follow certain activities? Did they show up the next morning instead of during the work? Did rest days help? Write a short summary at the top of the page listing the three things that bothered you most. Bring the full log and read the summary aloud at the start of the appointment.

Ask the clinician whether you should change how much you train while you wait for an answer. Do not decide that alone from a log. A professional who examines you can weigh your history, your exam, and your goals together.

When to stop and get help now

Stop the activity if a headache worsens, if you feel confused, if you vomit, if your vision changes, if you feel faint, or if you have weakness, numbness, or trouble speaking. Those signs call for prompt care, not a note for later. Trust your judgment about your own body, and do not push through warning signs to finish a set or a race.

A plain log will not settle anything on its own. It gives you and your clinician a clearer picture of what happened, when, and under what conditions. Keep it honest, keep it short, and keep it where you can find it.
