A study teamaffiliated to Baylor College of Medicine, Houston, USA first verifies from the“molecular level”, heart has its inherent “biological clock”, which conforms tohuman day and night rhythm. According to the suggestions of experts, we shouldbe orientated to the “biological clock” to protect heart, brain and vessels. WuZongui, Chief Physician of Department of Cardiovascular Internal Medicine ofShanghai Changzheng Hospital, and Professor Li Yong from Department ofCardiology of Hushan Hospital of Fudan University summarize the followingmoments:
Dawn: thisis the high-incidence moment of cerebral stroke and cardiac infarction. Thelack of water in the morning induces the blood concentration, an increase inblood viscosity, and a slowed pulse and heart rate, which is apt to causethrombi. Suggestions: old people should drink a cup to warm water after morningrise, avoid put forth their strength and hold the breath in defecation, eatless oily and salty foods in the morning, and do no do strenuous exercise.People with a high blood pressures should take antihypertensive drug at thistime and prevent the fluctuation in blood pressure.
9 to 11 am:the heart activities reach the peak, and people are apt to experience seriousarrhythmia. Suggestions: the people with poor heart conditions should avoidfluctuation of the emotional moods and take medicines before giving importantlectures.
After lunch:the diets will result in the fluctuation in blood pressure and blood glucose,especially in the old people with cardiovascular diseases whose amplitude inblood pressure drop is greater than that of the young people; this will furtherlead to the slowed blood flow, vascular congestion and thrombosis. Suggestions:1. Do not eat too much during the lunch. 2. Take a nap after meals (half anhour is the best). 3. Lie for a while after getting up and do not overexert.
After 3:00pm: it is suitable to do exercise such as rapid walking, body building andswimming. British researchers find that the afternoon exercise do the greatesthelp to sleep. At 10:00 pm, the body and brain are apt to enter the relativelyfatigue status so that they can fall in asleep rapidly.
9:00 to11:00 pm: this is the key moment in immune system regulation; in case of bingeovereating and excessive agitation at this time for a period of time, thepeople are apt to suffer from multiple diseases such as hypertension, diabetesmellitus and heart diseases. Suggestions: read books, listen to music, relaxcompletely, and enter the status for preparing sleep. As the cholesterolsynthesis in liver is the most active in the evening, the efficacy of takinganti-hyperlipemic drugs is better.
