Blood pressure is the measure of blood that is circulated by the heart. When the heart beats, it pumps blood through arteries at a rate that depends on a number of factors, such as age, genetics, lifestyle, gender, weight, smoking, cholesterol, diabetes, and physical activity. Blood pressure maintenance is important for living a long and fulfilling life, as poor blood pressure can influence a range of health concerns later on. Diet, exercise, and medication are the main aspects of blood pressure maintenance.

Hypotension, also known as low blood pressure, is when blood is insufficiently provided to the organs. This can lead to a number of health issues when organs are not supplied with an adequate amount of blood to function properly, such as light-headedness, dizziness, or even fainting if the brain is left without sufficient blood.

Both high and low blood pressure are dangerous and potentially life-threatening. High blood pressure, though, is a more common affliction, and is also thought of as more dangerous. Sleep apnea, kidney disorders, and thyroid disease can lead to high blood pressure. Age is also a main contributor, with nearly 75% of women and around 60% of men experiencing high blood pressure.
