🩺 Can low blood pressure be harmful? Safe Range, Causes, and Management Tips
Low blood pressure is often thought to be harmless, but it is not always safe. Generally, it is classified as hypotension when systolic blood pressure is 90mmHg or below or diastolic blood pressure is 60mmHg or below. However, numbers alone do not determine whether it is harmful. When accompanied by symptoms such as dizziness, fatigue, or blurred vision, it can significantly interfere with daily life, and in severe cases, may lead to fainting or reduced blood flow to organs. Understanding when low blood pressure becomes dangerous is therefore very important.
Compared to normal blood pressure, low blood pressure is not always considered a disease, but depending on the cause, it requires careful attention. Dehydration, endocrine disorders, medication side effects, and orthostatic hypotension are common triggers. Harvard Health Publishing emphasizes that it is important to consider not only the numbers but also the symptoms and overall health status.
What is normal blood pressure?
For most adults, normal blood pressure is defined as a systolic reading below 120mmHg and a diastolic reading below 80mmHg. However, this is not an absolute standard that applies to everyone. Factors such as age, body weight, lifestyle habits, and genetics can influence the ideal range. Harvard Health Publishing notes that interpreting normal blood pressure should take individual context into account.
Blood pressure can vary greatly throughout the day. It often fluctuates after waking in the morning, after meals, or following exercise. The “white coat effect,” in which readings rise temporarily due to anxiety at a clinic, is also common. Therefore, taking repeated measurements in different settings and times of day is the most accurate way to assess whether blood pressure is stably within the normal range.
Which is more important: systolic or diastolic?
A common question is whether systolic or diastolic pressure is more important. According to a study published in the New England Journal of Medicine, both numbers play a crucial role in predicting health outcomes. Systolic pressure reflects the force when the heart contracts and pumps blood, while diastolic pressure reflects the state when the heart relaxes and fills with blood.
The importance can vary with age. Among older adults, systolic blood pressure is often considered more significant, as it is closely linked with conditions such as arteriosclerosis. In younger individuals, however, diastolic blood pressure may more sensitively reflect health status. Therefore, it is essential to monitor both numbers together to create a management plan suited to one’s age and health conditions.
What is labile blood pressure?
Labile blood pressure refers to a condition where readings fluctuate significantly from one measurement to another. According to the Cleveland Clinic, this can be associated with factors such as stress, lack of sleep, caffeine intake, or changes in body weight. While occasional variability is not always harmful, repeated large fluctuations can put a strain on health.
Persistent labile blood pressure may increase the risk of cardiovascular and cerebrovascular diseases. If symptoms such as dizziness, headaches, or palpitations accompany the fluctuations, consulting a healthcare provider is essential. Keeping a blood pressure diary is also a helpful way to track changes and identify potential causes.
A Gift of Multisensory Therapy
Multisensory therapy can be a valuable aid in managing low or labile blood pressure. Begin with aromatherapy: add 3 drops of lavender oil, 2 drops of bergamot oil, and 2 drops of sweet orange oil to a diffuser. This blend helps relieve anxiety, ease tension, and contribute to stabilizing blood pressure. The calming effect promotes emotional balance, reducing fluctuations.
Music therapy is equally effective. Recommended pieces include Bach’s Air on the G String, Ludovico Einaudi’s Nuvole Bianche, and a nature track titled “Ocean Waves.” These sounds help calm the mind, steady the heart rate, and provide emotional support in the process of blood pressure management.

"Sometimes it is the smallest changes in daily life that protect us from the greatest dangers." — The Pursuit of Happyness. This quote applies directly to blood pressure management, where small lifestyle changes can become the most powerful defense over time.
I recall a patient who struggled with labile blood pressure. He often felt dizzy and fatigued, which disrupted his daily life. However, by committing to a daily 20-minute walk and practicing meditation with aromatherapy, his blood pressure became noticeably more stable within a month. His life grew more vibrant and confident.
The lesson is clear: the key to managing blood pressure does not lie in dramatic changes but in consistent, small practices. Start with a single small step today, and your body and mind will naturally follow the path of stability and healing.
