The immune system helps to prevent the onset of diseases and conditions. This is known to all. But, how many of you know that your body’s defence system can make you susceptible to certain health conditions too? Surprised? Don’t be.

According to a research published in the journal Free Radical Biology and Medicine, due to some unknown reasons, your immune cells start responding inappropriately by accumulating in the kidneys and shooting out highly reactive free radicals. These are called reactive oxygen species (ROS) as these radicals are a byproduct of our body’s use of oxygen, which is generally used to kill invaders by the immune system. However, in this case, excessive secretion of free radicals can lead to inflammation and raise your blood pressure, thus forcing the kidneys to hold onto more salt. This is what damages this vital organ.

By blood pressure, we mean the amount of resistance blood faces by the arteries while your heart is pumping. Certain factors including narrower arteries, obesity, lupus, kidney disease, type 2 diabetes, etc., increase the risk of hypertension. You have hypertension if the systolic value of your blood pressure is more than 140 mmHg and the diastolic value is more than 90 mmHg. The condition is characterised by symptoms including heart palpitations, dizziness, nausea, headache, breathlessness, etc.

In order to keep your blood pressure under control, you just need to make certain healthy changes in your lifestyle. You must opt for heart-healthy food including green veggies, fruits, whole grains, and fishes. Also, start indulging in physical activity. It cannot only help you maintain a healthy weight but also keep stress (one of the factors responsible behind hypertension) at bay. According to experts in the field, you should do 150 minutes of moderate physical activity in a week to keep your blood pressure under control. To manage stress, you can also go for meditation, yoga, deep breathing, massage, etc.
