Lunch is done. You have had a second cup of coffee, and the sofa has been very comfortable for about forty minutes.
You stand up to put the kettle back on, and for a second the room goes gray at the edges. It feels a bit like the end of a long movie, when the lights come up too slowly. Your hand finds the arm of the sofa without being asked. You wait. It passes.
Maybe this has happened before, and you haven’t thought much of it. After all, it clears in a few seconds. It can seem too minor to mention.
It does happen to a lot of people. It is also worth mentioning.
What happens in that gray second
When you stand, your body has to adjust your blood pressure quickly enough to keep blood flowing to your brain. For some people, the adjustment is slower or the drop is larger than it should be. The result may be a brief wave of dizziness, blurred vision or that gray feeling.
The medical name is orthostatic hypotension, also called postural hypotension. Cleveland Clinic describes it as a significant drop in blood pressure on standing, usually measured as at least 20 millimeters of mercury in the top number or 10 in the bottom number. It can occur after sitting or lying down and becomes more common with age.
Not every fleeting dizzy spell is orthostatic hypotension. Dehydration, medications and several other health conditions can cause similar symptoms. That is one reason not to diagnose it for yourself simply because it goes away quickly.
Why it deserves more than a shrug
The important question isn’t only why your vision dimmed. It’s whether you’re safe in the moment that follows.
The CDC’s brochure on postural hypotension explains that a drop in blood pressure on standing can increase the chance of falling.
Falls are already common among older adults. About one in four adults aged sixty-five and older reports a fall each year, according to CDC data.
If you’re lightheaded, even a few steps toward the kitchen or the stairs can be risky. The sensible response is to stop moving and sit or lie down somewhere safe until the feeling passes. If the problem keeps happening, tell your clinician rather than simply changing your routines to avoid standing.
When it is more than a gray second
Brief dizziness deserves a mention to your doctor, particularly if it is new, recurrent, worsening or started after a medication change. Fainting or a fall should prompt medical assessment, even if you soon feel better.
Some symptoms call for immediate emergency care. If dizziness comes with chest pain, severe difficulty breathing, sudden weakness on one side, trouble speaking or other possible stroke symptoms, call emergency services rather than waiting for an appointment. If you remain extremely dizzy, cannot safely stand or do not recover, seek urgent help.
For a mild spell that clears when you sit or lie down, make a note of when it happened and arrange to discuss it with your clinician. You don’t have to wait for a fall to bring it up.
When it tends to happen
In The Twenty Seconds Between Your Bed and the Door, I wrote about another risky moment: getting up to go to the bathroom at night, when you’re still half-asleep and may be unsteady. Sitting on the edge of the bed before standing is a useful precaution.
But postural dizziness isn’t limited to the nighttime. The CDC lists several situations where symptoms can appear:
when standing or sitting up suddenly;
in the morning;
after a large meal or alcohol;
during exercise or after straining on the toilet;
when you’re ill, dehydrated or feeling very anxious.
Very hot baths and showers can make symptoms worse for some people, too.
Read that list with your own day in mind. You may notice a pattern you hadn’t connected to standing up.
The pills in the cabinet
Sometimes these spells begin around the time a medication is started or its dose changes. That can be surprisingly easy to miss when the medicine was prescribed for a perfectly good reason.
The CDC lists some water pills, blood-pressure medications and antidepressants among possible contributors. It also mentions diabetes, certain heart or neurological conditions, dehydration, anemia and long periods of bed rest.
That doesn’t mean any one medicine is necessarily the cause. But if the spells started after a new prescription, tell your clinician exactly when. Bring a list of medications, including over-the-counter ones.
And don’t stop or reduce prescription medication on your own. A clinician can review whether the dose, timing or treatment should change.
What to do in the seconds after you stand
Most of the CDC’s practical advice costs nothing, although which steps are appropriate for you depends on your health and mobility.
Get up in stages. From bed, sit up first, rest on the edge of the bed, then stand. From a sofa or chair, move toward the front of the seat, put your feet flat on the floor and rise slowly. There’s no magic number of seconds that works for everyone.
Move a little first. Gently flex your ankles or open and close your hands before standing. If you’re steady once upright, light leg movements may help before you walk away. If you feel dizzy, sit back down rather than trying to march through it.
Give yourself something stable to hold. A fixed counter or properly secured handrail is better than furniture that might slide or tip.
Don’t walk while dizzy. Sit or lie down safely and wait for the symptoms to pass. If you feel faint, get assistance and seek medical advice, especially if this is new or recurrent.
Make standing tasks easier. Sitting for some kitchen preparation, dressing or washing can reduce long periods on your feet. In the bathroom, consider whether stable grab bars or a suitable seat would be safer than an improvised stool.
Drink enough for your circumstances. Dehydration can contribute to low blood pressure, but people with heart, kidney or other medical conditions may need fluid restrictions. Follow your clinician’s advice rather than forcing yourself to meet a generic number.
Avoid very hot showers or baths if they make you lightheaded, and take your time getting out.
Some people are advised to sleep with their head slightly raised. That’s a question to discuss with your clinician rather than a universal fix.
The simple habit to remember: don’t rush your first steps. Pause, make sure you’re steady, and only then move.
A week of writing it down
If the problem is mild and you already have a nonurgent appointment arranged, a short record can be useful. Don’t delay medical assessment for a week just to complete it if you faint, fall or have symptoms that concern you.
Keep a note on your phone or a card by the sofa. Each time it happens, write down the time, what you had just been doing, how long it lasted and whether anything changed recently.
For example:
“Tuesday, 1:30 p.m. — stood up after lunch; vision dimmed for a few seconds.”
“Thursday, 7:15 a.m. — dizzy getting out of the shower.”
“Saturday, 10 a.m. — symptoms began after medication was changed.”
Those details are often more useful in an appointment than trying to remember how often you felt “a bit off.” They can help a clinician decide what to investigate.
The three-minute test worth asking for
There is a straightforward clinical assessment for checking whether your blood pressure drops when you stand. It’s called measuring orthostatic blood pressure.
The CDC’s STEADI instructions describe the procedure: rest lying down for five minutes; measure blood pressure and pulse; then repeat the measurements after standing for one minute and again after three minutes. A drop of at least 20 mm Hg in the top number or 10 mm Hg in the bottom number, or symptoms such as dizziness, is considered abnormal during the assessment.
This should be done with appropriate supervision, particularly if standing makes you feel faint. A routine blood-pressure measurement taken while sitting won’t necessarily reveal a problem that happens when you stand.
You can ask:
“I’ve been getting dizzy when I stand up. Could we check my blood pressure lying down and then standing?”
Bring your medication list and any notes about when the symptoms started. It’s a simple question, and you deserve a careful answer.
If a symptom gets dismissed as “just your age,” I also wrote about ways to ask for a more complete explanation in Why “Acting Your Age” Is Bad Medical Advice.
The next time you stand, there is no need to race to the next room. Take a moment, notice how you feel and steady yourself before you set off. And if that gray second keeps visiting, bring it up with your doctor.

P.S. The advantage of getting older is learning or education. So why collect a brain of information if one is just going to refuse to use that information.
Thank you
….no need to wait for a fall and broken bones (or something worse) to learn these very valuable lessons.
