Eat more salt
You may have heard that a diet low in sodium (salt) is good for people with high blood pressure. This advice is correct, but not appropriate for everyone who has blood pressure conditions. If you have low blood pressure, you need more salt in your diet not less.
Adding more salt to your diet is an easy way to raise your blood pressure [4], which is why doctors advise hypertensive people against taking much. Salt increases blood pressure by affecting hormones that control your body’s water balance.
Low blood pressure is not a pass to consuming high amounts of salt. Take moderate amounts of salt and it will go a long way in improving your low blood pressure.
