A blood pressure of 105/61 is a good reading. It falls within the normal range, sitting comfortably below the 120/80 threshold that marks the upper boundary of healthy blood pressure. For most people, this number is nothing to worry about and actually suggests a lower cardiovascular risk profile.
What 105/61 Means
The top number (105) is your systolic pressure, the force your blood exerts against artery walls each time your heart pumps. The bottom number (61) is your diastolic pressure, the force between beats while your heart refills with blood. Both numbers matter, and in your case, both are in a healthy zone.
Normal blood pressure is defined as below 120/80. A reading of 105/61 clears that mark with room to spare. There’s no official lower cutoff for “too low” the way there’s a cutoff for high blood pressure. Instead, doctors evaluate low blood pressure based on how you feel, not just the numbers on the cuff.
Why It’s Actually a Good Sign
Lower blood pressure generally means less strain on your heart and blood vessels over time. Large clinical trials, including the landmark SPRINT trial, have consistently shown that lower systolic pressure is associated with fewer cardiovascular events and lower mortality. Even diastolic readings in the low 60s don’t appear to increase risk in otherwise healthy people.
A reading like 105/61 is common among athletes and physically active younger adults. Research published in the British Journal of Sports Medicine found that systolic blood pressure in elite athletes ranged from about 112 down to lower values, with diastolic readings averaging as low as 59. If you’re active and healthy, a reading in this range is typical.
When a Low-Normal Reading Could Be a Problem
The only time 105/61 would raise concern is if you’re experiencing symptoms. Most healthcare professionals consider blood pressure too low only when it causes noticeable problems. Symptoms of blood pressure that’s functionally too low for your body include:
- Dizziness or lightheadedness, especially when standing up
- Blurred or fading vision
- Fatigue that doesn’t improve with rest
- Trouble concentrating
- Nausea
- Fainting
If you regularly get readings around 105/61 and feel perfectly fine, you likely don’t need any treatment or changes. Your body has adapted to this pressure, and it’s working well for you. People who have naturally low blood pressure often stay that way their entire lives without any complications.
On the other hand, if this reading is new for you and you’ve been feeling off, it’s worth paying attention. A sudden drop from your usual numbers can matter more than the absolute value. Someone who normally runs 130/85 and suddenly reads 105/61 may feel dizzy even though the number itself looks healthy on paper.
Getting an Accurate Reading
A single reading doesn’t tell the whole story. Blood pressure fluctuates throughout the day based on stress, hydration, meals, and activity. If you’re measuring at home, the CDC recommends a few steps to get a reliable number:
Avoid food and drinks for 30 minutes beforehand, and empty your bladder before sitting down. Rest in a comfortable chair with back support for at least five minutes before taking the reading. Keep both feet flat on the floor, legs uncrossed, and rest your cuffed arm on a table at chest height. The cuff should sit against bare skin, not over a sleeve. Don’t talk during the measurement.
Taking two or three readings a minute apart and averaging them gives you a more accurate picture than relying on a single measurement. If you’re tracking over time, measure at roughly the same time of day for consistency.
What to Watch For Over Time
If your blood pressure stays in this range and you feel well, you’re in a good spot. The main thing to watch for is any pattern of symptoms like persistent fatigue, frequent lightheadedness when you stand up, or episodes of near-fainting. These could signal that your pressure is dipping lower than your body can comfortably handle, sometimes due to dehydration, medication side effects, or other underlying causes.
For most people reading this, though, the short answer is reassuring: 105/61 is a healthy blood pressure. It puts you at lower risk for heart disease and stroke compared to higher readings, and it’s a number most cardiologists would be happy to see.
