Identification

• Normal blood pressure levels for humans age 20 years and older are 90 to 119 for systolic blood pressure and 60 to 79 for diastolic blood pressure, according to the American Heart Association.
  
  

Function

• Normal blood pressure levels are used as a way to evaluate a person's overall health, and readings are done as a part of regular medical checkups to screen for problems.
  
  

Features

• According to the Mayo Clinic, men are more likely to have higher blood pressure at younger ages compared to women. But women are more likely to be diagnosed with high blood pressure at older ages, especially after menopause.
  
  

Considerations

• According to the Mayo Clinic, humans may not have any symptoms when their blood pressure is in the range of normal levels. The damage caused by high blood pressure can cause increasing damage to the heart over time.
  
  

Misconceptions

• Blood pressure levels in humans that are below normal may be as dangerous to the body as high blood pressure levels.
  
  

Prevention/Solution

• Maintaining a normal blood pressure range can be done through actions such as regular exercise and maintaining a heart healthy diet. According to the American Heart Association, taking an aspirin may also help maintain a normal blood pressure level in humans.
  
  

Warning

• Humans with blood pressure that is uncontrolled at dangerous levels can cause damage to the heart, kidneys, eyes and brain and may result in death from a heart attack or stroke.
