"Old Zhang, you wake up so early, it's not good for you," said Dr. Chen Jian Guo, looking up from the examination report at the 54-year-old Zhang Dapeng, a chief technician at a state-owned enterprise. Zhang Dapeng had a demanding job and lived a very regular life, waking up at 5:30 a.m. every day for his morning jog, rain or shine. Recently, due to the hot weather, Zhang Dapeng decided to join a tour group to escape to the mountains. Before the trip, he decided to get a checkup, considering the rugged mountain roads. He needed to ensure his body was in good shape. However, the results of this examination surprised him.

The doctor told him his blood pressure was high, and his cholesterol was also slightly elevated. This scared him, as he considered himself a model of healthy living. He woke up early and exercised daily. How could his body be having problems? Dr. Chen Jian Guo looked at Zhang Dapeng's confusion and couldn't help but smile. "Old Zhang, have you always thought that waking up early for morning jogs is good for your health?"

Zhang Dapeng nodded. "Of course, waking up early to exercise is a well-known good habit."

"But do you know, there's a recent study involving 126 experts that shows waking up too early can actually have adverse effects on your blood vessel health. Simply put, the earlier you wake up, the greater the pressure on your blood vessels, which can actually affect blood circulation."

Zhang Dapeng widened his eyes. "What? This completely contradicts what we usually believe!"

"Don't worry, I'll explain it to you slowly," Dr. Chen Jian Guo smiled and waved his hand. "We often believe that waking up early is good, but waking up too early, especially before dawn, is a significant impact on your body's biological clock. Your body has its own rhythm, and waking up too early can disrupt this rhythm, leading to the sympathetic nervous system becoming activated too early, increasing blood pressure and heart rate, and putting a strain on your heart and blood vessels."

Zhang Dapeng listened and nodded, but he was still a bit skeptical. "Does waking up later really make your blood vessels more open?"

"That's right," Chen Jian Guo continued to explain. "Studies have shown that there is a connection between your wake-up time and the dilatation of your blood vessels. Those who wake up after 7 a.m. each day have better blood vessel dilatation abilities, and their blood flow is more smooth. This is because by this time, the body has gradually entered the daytime metabolic mode, and the pressure on the blood vessels is relatively lower."

Hearing this, Zhang Dapeng couldn't help but think back on his regular routine. "Does that mean my daily wake-up time of 5 a.m. has been causing my blood pressure to rise?"

"Precisely," Chen Jian Guo nodded. "Many people, like you, are used to waking up early, even believing that earlier is better. However, waking yourself up from your sleep before your body is ready can not only put stress on your blood vessels but also lead to chronic fatigue and increase the risk of metabolic syndrome."

"No wonder I've been feeling sluggish lately, and my morning runs have been less energetic," Zhang Dapeng suddenly understood.

"This is also a self-protective response from your body," Chen Jian Guo explained. "Long-term early waking can lead to an increase in your cortisol levels. This is a stress hormone that causes vasoconstriction, which in turn increases blood pressure. Over time, this can lead to reduced blood vessel elasticity and an increased risk of atherosclerosis."

Zhang Dapeng felt a bit scared. "So, should I wake up later?"

"That's right," Dr. Chen Jian Guo said. "Especially now that you're over fifty, your bodily functions are gradually declining. You should pay attention to adjusting your sleep schedule. You can try to adjust your wake-up time to between 6:30 and 7:00 a.m. This way, you can ensure enough sleep, and your blood vessels can get a full rest."

Zhang Dapeng nodded repeatedly. "So, I should adjust my morning run time as well?"

"Of course," Chen Jian Guo smiled. "Actually, the best time for a morning run is between 7 and 8 a.m. The temperature is moderate, the sun isn't too strong, and the air quality is better, making it ideal for outdoor exercise. Besides, by this time, your body has fully recovered from sleep, your blood vessels have the best dilatation ability, and you can better handle the stress of physical activity."

Zhang Dapeng took notes while thinking that he needed to readjust his sleep schedule and no longer be a "wake-up-too-early" running enthusiast. However, he was still a bit confused. "Doctor, my cholesterol is also a bit high. Is it related to my early wake-up time?"

"You've hit the nail on the head," Chen Jian Guo nodded. "Waking up early can indeed affect metabolism, especially for those who are used to morning runs on an empty stomach. During an empty stomach, high-intensity exercise can trigger an emergency mechanism in your body, breaking down fat and protein to provide energy. But this can also cause blood lipid levels to fluctuate. If this continues for a long time, it can make it difficult to control blood lipids."

Zhang Dapeng was astonished. "So, my morning runs on an empty stomach are essentially 'self-destruction'?"

"You can't say that," Chen Jian Guo smiled. "Exercise itself is good for your body. It's just a matter of the method. You can drink some warm water and eat something easily digestible, like a banana or a slice of whole wheat bread, after waking up. Then, wait for your blood sugar to stabilize before starting your morning run. This can not only prevent the harm of exercising on an empty stomach but also help your body better burn excess fat."

Zhang Dapeng carefully noted these suggestions, determined to start living scientifically and stop 'blindly waking up early'. However, he couldn't help but ask, "Doctor, if waking up late is good for your blood vessels, what if I'm busy with work, go to bed late, and wake up late? Would that have other health effects?"

Chen Jian Guo smiled and patiently explained, "Going to bed late and waking up late does indeed have some benefits for your blood vessels. However, the premise is that you need to ensure enough sleep time. Adults need 7 to 8 hours of sleep each day. Lack of sleep can put your body in a state of constant stress, putting more pressure on your cardiovascular system."

Chen Jian Guo continued to say, "So, the key isn't what time you wake up, but whether you've ensured adequate rest. Even if you go to bed late and wake up late, your body won't recover fully without enough rest, and you'll still experience fatigue, weakened immunity, and other problems. That's why we advocate going to bed early and waking up early, not simply waking up late."

Zhang Dapeng nodded thoughtfully after listening. "It seems I need to adjust not only my wake-up time, but also I need to go to bed earlier."

Dr. Chen Jian Guo nodded in agreement. "That's right. Good sleep habits are essential for protecting your cardiovascular health. So, Old Zhang, waking up early is indeed beneficial, but don't blindly pursue it. Finding the right rhythm for yourself is the most important thing."

Zhang Dapeng finally understood and decided to stop blindly waking up early from that day forward. Instead, he would adjust his sleep schedule according to his body's needs. This way, he could truly nourish and protect his blood vessels.
