When people talk about blood pressure, most attention usually goes to the top number in a blood pressure reading.
However, doctors say the bottom number is also very important and should not be ignored. This number is called diastolic blood pressure, and it measures the pressure inside the arteries when the heart is resting between beats.
A blood pressure reading always includes two numbers. The first number, called systolic pressure, shows how much pressure is in the arteries when the heart pumps blood out to the body. The second number, called diastolic pressure, shows the pressure when the heart relaxes before the next beat.
Many people focus mainly on systolic blood pressure because it is often linked to heart attacks and strokes, especially in older adults.
But high diastolic blood pressure can also be dangerous. If the bottom number stays too high over time, it means the heart and blood vessels remain under stress even when the heart should be resting.
Doctors generally consider a diastolic pressure above 80 millimeters of mercury, or mmHg, to be higher than normal. Over time, this extra pressure can damage blood vessels and increase the risk of serious health problems such as heart disease, stroke, kidney disease, and circulation problems.
The good news is that there are many simple and effective ways to lower diastolic blood pressure naturally and improve heart health.
One of the most important steps is improving diet. Researchers have found that healthy eating patterns can significantly lower blood pressure in just a few weeks. One of the best-known plans is the DASH diet, which stands for Dietary Approaches to Stop Hypertension.
The DASH diet encourages people to eat more fruits, vegetables, whole grains, beans, nuts, lean meat, and low-fat dairy products.
At the same time, it limits foods high in sugar, unhealthy fats, and processed ingredients. Studies published in the Journal of the American Heart Association have shown that this diet can help lower blood pressure quite quickly in many people.
Salt intake is another major factor affecting blood pressure. Sodium, which is found in salt, causes the body to hold onto extra water. This extra fluid increases pressure inside blood vessels and makes the heart work harder.
Many people consume much more salt than they realize because processed and packaged foods often contain large amounts of sodium. Fast food, canned soups, chips, frozen meals, sauces, and processed meats are some of the biggest sources.
The American Heart Association recommends that adults try to keep sodium intake below 2,300 milligrams per day. Ideally, many people should aim for around 1,500 milligrams daily, especially if they already have high blood pressure.
Simple changes such as cooking more meals at home, reading food labels carefully, using herbs instead of salt, and avoiding highly processed foods can make a big difference over time.
Exercise is another powerful way to lower blood pressure naturally. Physical activity strengthens the heart so it can pump blood more efficiently. When the heart becomes stronger, it does not need to work as hard to move blood through the body, which lowers pressure inside the arteries.
Health experts recommend at least 150 minutes of moderate exercise each week. Activities such as brisk walking, cycling, swimming, dancing, or light jogging can all help improve blood pressure and overall heart health.
Regular movement also helps with weight control, stress reduction, blood sugar balance, and better sleep, all of which are connected to healthier blood pressure levels.
Stress itself can strongly affect blood pressure. When people are stressed or anxious, the body releases hormones that raise heart rate and tighten blood vessels. Frequent or long-term stress may contribute to ongoing blood pressure problems.
Because of this, relaxation techniques can be very helpful. Deep breathing exercises, mindfulness meditation, yoga, and spending time outdoors may help calm the nervous system and reduce blood pressure.
A study published in the journal Psychosomatic Medicine found that mindfulness meditation helped lower both systolic and diastolic blood pressure in many participants.
Alcohol can also influence blood pressure. Small amounts may not cause major problems for some people, but heavy drinking can increase blood pressure over time and damage the heart. Health experts generally recommend that men limit alcohol to no more than two drinks per day and women to no more than one.
Another useful habit is checking blood pressure regularly at home. Home monitors allow people to track their numbers over time instead of relying only on occasional readings at a doctor’s office. This can help patients and doctors better understand whether lifestyle changes or medications are working.
Doctors say it is important to remember that blood pressure naturally changes throughout the day depending on activity, stress, sleep, meals, and other factors. Tracking readings regularly can help identify patterns and provide a clearer picture of overall heart health.
High diastolic blood pressure may sound worrying, but in many cases it can be managed successfully through healthy habits and proper medical care.
Eating healthier foods, exercising regularly, reducing salt, managing stress, limiting alcohol, and following medical advice can all help lower blood pressure and protect the heart.
Even small changes made consistently over time can lead to major health improvements. By paying attention to both numbers in a blood pressure reading, people can take important steps toward living longer, feeling healthier, and reducing their risk of serious disease.
If you care about high blood pressure, please read studies that early time-restricted eating could help improve blood pressure, and natural coconut sugar could help reduce blood pressure and artery stiffness.
For more health information, please see recent studies about added sugar in your diet linked to higher blood pressure, and results showing vitamin D could improve blood pressure in people with diabetes.
