A blood pressure of 100/60 mm Hg falls within the normal range and is generally a healthy reading. The 2025 AHA/ACC guidelines define normal blood pressure as below 120/80, which means both your systolic (top) number and diastolic (bottom) number are comfortably within that window. Whether it’s “good” or a potential concern depends entirely on how you feel at that number.
Where 100/60 Falls on the Chart
Blood pressure in adults is grouped into four categories:
- Normal: below 120/80
- Elevated: 120 to 129 systolic with diastolic still under 80
- Stage 1 hypertension: 130 to 139 systolic or 80 to 89 diastolic
- Stage 2 hypertension: 140 or higher systolic, or 90 or higher diastolic
At 100/60, you’re well below the threshold for elevated blood pressure. The overarching treatment goal for all adults under the current guidelines is to stay under 130/80, and you’re already there by a wide margin. For most people, this reading is something to feel good about, not worry about.
Who Naturally Runs Low
Some people consistently read around 100/60 or even lower without any health issues. This is especially common in younger adults, physically active people, and women. Endurance athletes often have lower resting blood pressure because their hearts pump blood more efficiently with each beat, so less pressure is needed to circulate it.
Pregnancy can also push blood pressure lower, particularly during the first and second trimesters, as the circulatory system expands rapidly to support the growing baby. A reading of 100/60 during pregnancy is not unusual, though any sudden drop or new symptoms should be flagged to your provider.
If 100/60 is your baseline and you feel fine, it’s not just acceptable, it’s protective. Lower blood pressure within normal limits is associated with reduced long-term risk of heart disease, stroke, and kidney damage.
When 100/60 Could Be a Problem
Blood pressure only counts as “too low” when it causes symptoms. There’s no hard cutoff number the way there is for high blood pressure. The same reading that’s perfectly healthy in one person can make another feel terrible. The symptoms to watch for include:
- Dizziness or lightheadedness, especially when standing up from sitting or lying down
- Blurred vision
- Nausea
- Fatigue that feels disproportionate to your activity level
- Difficulty concentrating
- Fainting or near-fainting
These symptoms tend to show up most when you change positions quickly, like getting out of bed in the morning or standing up after a long stretch on the couch. Occasional lightheadedness from time to time can be caused by something as simple as spending too much time in the sun or in a hot tub. But if it’s happening regularly at this blood pressure, that pattern is worth investigating.
Common Reasons Blood Pressure Drops
If 100/60 is new for you, or lower than your usual reading, a few common factors could explain the shift. Dehydration is one of the most frequent culprits. When your blood volume drops from not drinking enough fluids, your pressure drops with it. This is especially relevant during hot weather, illness, or after exercise.
Certain medications can also lower blood pressure as either a primary effect or a side effect. Blood pressure drugs, some antidepressants, and medications for prostate conditions are common examples. If you recently started or changed a medication and noticed your readings dropping, that connection is worth discussing with your prescriber.
Other contributing factors include prolonged bed rest, nutritional deficiencies (particularly iron or B12), and conditions that affect how the nervous system regulates heart rate and blood vessel tone. Older adults are more susceptible to these nervous system changes, particularly those with conditions like Parkinson’s disease that affect the body’s automatic functions.
A Specific Type to Know About
One form of low blood pressure, called neurally mediated hypotension, mostly affects young adults and children. It happens after standing for long periods and results from a miscommunication between the heart and brain. The brain essentially sends the wrong signal, telling the heart to slow down and blood vessels to widen at the exact moment the opposite should happen. If you notice that your symptoms consistently appear after standing in line, at concerts, or during long ceremonies, this could be the pattern.
Simple Ways to Raise Low Blood Pressure
If your 100/60 reading comes with symptoms, a few practical strategies can help bring your numbers up slightly. The most straightforward one may surprise you: eat more salt. While people with high blood pressure are told to cut sodium, individuals with low blood pressure benefit from increasing it. Some physicians recommend at least 6 grams of salt daily for people with low blood pressure, which is about a teaspoon. Salt tablets are sometimes preferred over simply eating salty foods, since they allow more precise dosing.
Beyond salt, other strategies include:
- Drinking more fluids throughout the day, especially water
- Eating smaller, more frequent meals rather than large ones (big meals can divert blood flow to the digestive system and temporarily lower pressure further)
- Limiting or avoiding alcohol, which dilates blood vessels and can worsen drops
- Standing up slowly and giving your body a few seconds to adjust before walking
- Regular exercise, which strengthens your cardiovascular system’s ability to adapt to position changes
The Bottom Line on Your Reading
A blood pressure of 100/60 is normal by every current guideline. If you feel well, have energy, and don’t get dizzy when you stand up, this reading puts you in a favorable position for long-term heart health. If you’re experiencing symptoms like regular lightheadedness, fatigue, or fainting, the number itself isn’t dangerous, but the symptoms deserve attention. The distinction is simple: 100/60 without symptoms is a good blood pressure. 100/60 with symptoms is a signal to look deeper.
