In the silence of the night, the city falls asleep, and many people toss and turn in bed, unable to fall asleep. It's not just a worry about insomnia, it's a health wake-up call behind it. When night falls, the brain should go to rest, but for those who suffer from sleep, it is also a time when cardiovascular and cerebrovascular health is threatened.
Sleep, a natural process that we go through every day, is much more than simple rest. It is the repair time of the body and mind, and it is a critical moment for the regulation and recovery of the cardiovascular and cerebrovascular systems. During deep sleep, the heart beats slower, blood pressure lowers, and the brain recovers from the day's exertion. However, when sleep is disturbed, all these regulatory processes are affected, and the cardiovascular and cerebrovascular systems are also affected.
Not only that, scientific research has revealed that persistent sleep disorders are closely related to cardiovascular and cerebrovascular diseases such as hypertension, heart disease, and stroke. It seems that every toss-and-turn night is silently increasing the risk of these diseases. However, this is not an irreversible fate. Understanding the relationship between sleep and cardiovascular and cerebrovascular health, and mastering the correct way to fall asleep, can effectively reduce these risks.
Sleep, a process that everyone goes through every day, has a significant impact on blood pressure. It is widely recognized that sleep is seen as a critical moment of physical and mental recovery. But when this process is disrupted, such as lack of sleep or poor sleep quality, its impact on the cardiovascular system becomes even more important.
Studies have found that sleep deprivation leads to increased activity of the sympathetic nervous system, which can cause an increase in blood pressure. Deep sleep, especially rapid eye movement (REM) sleep, is essential for regulating blood pressure. At this stage, the heart rate and breathing become irregular, and blood pressure also experiences fluctuations. This cyclical fluctuation is important for maintaining blood vessel elasticity and normal blood pressure levels.
In addition, sleep-disordered breathing, such as sleep apnea, has a direct impact on blood pressure. In this condition, people repeatedly experience pauses in breathing and restarts breathing during sleep, causing oxygen levels to drop, which in turn triggers an increase in blood pressure.
Long-term sleep problems not only lead to fatigue, but more seriously, they are closely related to the development of cardiovascular and cerebrovascular diseases. Cardiovascular and cerebrovascular diseases, including coronary artery disease, heart attack, stroke, etc., are one of the major threats to health worldwide.
Studies have shown that sleep disorders, especially persistent sleep deprivation, can lead to impaired vascular endothelial function and increased inflammatory responses, both of which are key factors in the development of cardiovascular and cerebrovascular diseases. In addition, sleep deprivation can also lead to hormonal imbalances, such as increased cortisol levels, which in turn affect the cardiovascular and cerebrovascular systems.
Another aspect of concern is that long-term sleep deprivation may lead to unhealthy lifestyle changes, such as unhealthy eating habits, lack of exercise, etc., which further increase the risk of cardiovascular and cerebrovascular diseases.
The impact of the sleep environment on sleep quality should not be underestimated。An ideal sleeping environment should be quiet, comfortable, dark and cool. These factors work together to help people fall asleep faster and sleep deeper for longer.
Reducing noise levels is an important step. Noise not only prolongs the time it takes to fall asleep, but it also affects the continuity of sleep. Using earplugs or adding something to your bedroom that absorbs sound, such as heavy curtains, can be an effective way to reduce noise.
It's just as important to adjust the light. The body's biological clock is very sensitive to light, especially blue light, which inhibits the production of melatonin, a key hormone that regulates the sleep-wake cycle. Therefore, avoid electronic devices before bed and use blackout curtains to create a dark sleeping environment.
Maintaining the right temperature is also key。It is generally believed that a cooler environment is more conducive to sleep, around 16 to 18 degrees Celsius is ideal.
In addition to optimizing your sleep environment, changing some daily habits is also essential to promote a good night's sleep。The adjustment of these habits can not only improve sleep quality, but also help reduce the risk of cardiovascular and cerebrovascular diseases.
First, adjust your eating habits. Avoid foods and drinks that are high in fat, sugar, and caffeine at night, as these can interfere with sleep。Instead, choosing foods rich in tryptophan, such as bananas and oats, can help improve sleep quality.
Second, get a moderate amount of physical activity on a regular basis. Proper exercise can not only improve sleep quality, but also improve cardiovascular health. However, it is important to note that strenuous exercise should be avoided before bedtime, as this may lead to excitement and in turn affect sleep.
Finally, establish a regular sleep routine. Try to go to bed and wake up at the same time** every day, even on weekends. This can help adjust the body's internal clock and promote better sleep quality.
