Blood pressure is affected by a variety of factors, such as mental state, sleep state, body fat rate, diet, exercise, lipid profile, drug effects, smoking, excessive alcohol consumption, family genetics, environmental factors, weather factors, etc. Stress, agitation and mental tension can affect. Excessive salt intake during meals, high body fat rate due to weight gain, and low exercise in general can also affect, and poor air quality in the environment cannot be excluded. Excessive smoking causes the sympathetic nerve endings to release too much noradrenaline, resulting in higher blood pressure, and women taking birth control pills can also affect blood pressure. Poor breathing during sleep breathing and blocked nasal ducts can also affect it. Blood pressure becomes lower in summer when the temperature is high and higher in winter when it is colder. Loud noise, blinding light, skin contact with too icy objects, pain, and other neurological stimuli can also temporarily increase blood pressure. Holding urine and having a distended bladder can also increase blood pressure, which gradually returns to normal after urination. Blood pressure is affected by many factors, and a regular, healthy lifestyle is the best way to make it stable.
