Sleep is an indispensable basic activity of human life, and one third of the time is spent in sleep. A good sleep can make people energetic, clear-headed and quick-thinking. On the contrary, sleep disorder will not only affect people's mood, cognitive function, memory and long-term accumulation, but also lead to systemic and multi-organ damage, including cardiovascular health. People with irregular schedules are more likely to get fat. The study found that people who go to bed early and get up early often eat breakfast half an hour after getting up, while those who often stay up late are more likely to eat midnight snack to supplement calories. People secrete leptin during sleep, and people who stay up late are more likely to get fat. The influence of obesity on cardiovascular system has been recognized.
After chronic insomnia, the incidence of cardiovascular diseases increased significantly. Insomnia will increase the risk of cardiovascular disease and increase the mortality of cardiovascular disease. Insomnia patients are more likely to suffer from cardiovascular diseases such as hypertension, hyperlipidemia and metabolic syndrome. When people fall asleep, the whole body and mind will relax, the heart rate and blood flow in the coronary artery will decrease slightly, and the resistance in the coronary artery will increase. Patients with coronary heart disease have worse blood circulation because of coronary artery stenosis. If you don't sleep well, it will further increase the burden on the heart, lead to the instability of myocardial bioelectricity, and affect the normal contraction and heart rhythm of myocardium. These are all important risk factors leading to coronary heart disease.
Emotional impulse is also accompanied by poor sleep quality, because under the premise of poor sleep quality, our brain will send out negative or negative emotions, which will affect our daily work and interpersonal relationships, and lead to irritability, depression and other phenomena. If we are not careful, we may attack others or hurt ourselves. Poor sleep quality will lead to increased levels of hormones and inflammatory substances in the blood. If the lack of sleep lasts for five days, people's heart function will be weakened, increasing the risk of cardiovascular disease. People with poor sleep quality for a long time are most likely to suffer from heart disease. Once a heart attack occurs, it can range from angina pectoris to myocardial infarction.
