Blood pressure rhythm:
Normal blood pressure often presents a certain changing rhythm, that is, the blood pressure is low at night, rising from 4:00-5:00 in the morning, basically reaching the peak at 6:00-8:00 in the morning and then declining steadily, and 16:00-18 in the afternoon: There was a small peak again at 00 and then gradually decreased, and it was at a trough at 2:00-3:00 at night. Through the promotion of ambulatory blood pressure monitoring technology for 24 hours or longer, people have a better understanding of this diurnal variation of blood pressure.
According to the difference in blood pressure levels between day and night, circadian rhythm fluctuations can be divided into:
1. Dipper type hypertension - the average nighttime blood pressure is 10%-20% lower than the daytime average.
2. Ultra-dipper or deep-dipper hypertension—the blood pressure drops by more than 20% at night.
3. Non-dipper type hypertension - nocturnal blood pressure drop is less than 10%.
The relationship between heart rate and body temperature:
An increase in body temperature increases the heart rate. Every time the body temperature rises by 1 degree, the heartbeat generally speeds up 10 times, which is a normal heart rate response accompanied by fever. As the body temperature rises, the metabolism of the human body increases, and the heart rate increases accordingly to ensure that the body can work normally. The body temperature drops and the heart rate slows down.
A normal heartbeat is 60 to 100 beats per minute. If it exceeds 100 beats per minute, it is called tachycardia , and if it falls below 60 beats per minute, it is called bradycardia . A person's heart rate is not fixed and is affected by many factors, including body temperature, emotion, exercise, diet, sleep, disease, drugs and other factors. If you have angina pectoris , heart failure , myocarditis , hyperthyroidism and other diseases, your heart rate will increase.
A faster heart rate will speed up the metabolism in the body, which will increase the body temperature. (heart rate affects body temperature)
Blood sugar rhythm:
The fasting blood sugar value of normal people is 3.9-6.1mmol/L, and the blood sugar value is less than 7.7mmol/L two hours after a meal. Generally, the blood sugar value is the highest half an hour to one hour after a meal, and generally no more than 10.0mmol/L is normal. If the patient's random blood glucose value exceeds 11.1mmol/L, diabetes may occur , and further checks should be carried out on fasting and two-hour postprandial blood glucose values.
Normal people’s blood sugar changes like this, fasting is the lowest, blood sugar immediately rises to 2 hours after a meal, and then begins to drop, and gradually drops to fasting blood sugar level, three meals have this fluctuation rule.
