In my career as a family physician, I often encounter questions from patients about sleep and eating habits. One night, a thin middle-aged man came to my clinic with exhaustion written all over his face. He told me that in order to lose weight, he tried skipping meals at night, hoping that this would help him manage his weight. His question is simple but thought-provoking: Is falling asleep hungry with more benefits or disadvantages?
This may seem like a simple question, but behind it lies the complexity of health management. We all know that a good night's sleep is essential for health, and hunger can seriously affect the quality of sleep.
Popular science: The relationship between hunger and sleep
Many people may have experienced lying in bed at night, their stomachs "growling", and hunger pangs making it difficult to toss and turn, making it difficult to sleep. In fact, the relationship between hunger and sleep is very close, and understanding this relationship can help us better manage our lifestyle and sleep quality.
1. Hunger interferes with falling asleep
When you feel hungry, your body produces a substance called hunger hormone, scientifically known as ghrelin. This hormone sends signals to the brain that the body needs food. This physiological signal can interfere with the brain's resting patterns, causing difficulty falling asleep.
2. Affect sleep quality
Even if you fall asleep successfully while starving, sleep quality may suffer. Studies have shown that hunger may not only shorten the deep sleep phase, but may also increase the number of nighttime awakenings. This is because low blood sugar levels activate our emergency system, the sympathetic nervous system, which puts us in a more alert state.
3. Relationship with appetite
Prolonged hunger not only affects sleep that night, but can also affect dietary choices the next day. Sleep deprivation can increase appetite, especially cravings for high-calorie foods. This is because when you don't get enough sleep, levels of leptin, another hormone that regulates appetite, decrease, while levels of adrenocorticotropic hormone, the hormone that promotes appetite, rise.
4. Find balance
Ideally, avoid heavy meals within two to three hours of bedtime, but at the same time don't be in a state of intense hunger. Choosing something light, such as a small portion of yogurt or a few slices of fruit, can help stabilize blood sugar levels and avoid waking up during the night without overly irritating your stomach.
Analysis of benefits
When discussing the benefits of falling asleep at night with hunger, while this may sound like a beneficial weight loss strategy for some, the reality may be more complicated. Here are some of the possible benefits, but they need to be realized with the right situation and moderate management:
1. May help reduce calorie intake
If you don't eat at night or eat less, you may have a reduced calorie intake throughout the day, which can be beneficial for people who want to control their weight. But the key is to make sure you're getting enough nutrients during the day and not causing you to be overly hungry at night.
2. Promotes blood sugar control
For some people with diabetes or those who need to control their blood sugar levels, avoiding excessive eating after dinner may help prevent wild fluctuations in blood sugar levels at night, which can help with overall blood sugar management. However, this needs to be done under the guidance of a doctor to ensure health and safety.
3. Enhances the release of growth hormone
Some studies have shown that sleeping while starved may increase the release of growth hormone, which plays an important role in repairing body tissues, promoting muscle growth, and breaking down fat. However, prolonged starvation may cause the body to adapt to lower growth hormone production, so this benefit may be temporary.
4. Improve metabolic efficiency
Intermittent fasting has been shown in some studies to increase metabolic efficiency and improve the way the body uses food. Not eating at night may be one way to implement this eating pattern, but the key is to maintain a balanced nutrition, which is not suitable for everyone.
Bad analysis
When exploring the downsides of falling asleep hungry at night, we find that the potential negative effects may far outweigh any short-term benefits. Here are some specific problems that falling asleep hungry can cause:
1. Decreased sleep quality
When the body feels hungry, levels of hormones such as ghrelin increase, and the elevation of these hormones can lead to sleep disruption and decreased sleep quality. Studies have shown that a good night's sleep is essential for maintaining normal physiological functions, and that hunger can make it difficult for a person to fall into a deep sleep, which can affect cognitive function and physical performance the next day.
2. Metabolic disorders
Prolonged starvation can lead to a decrease in the body's metabolic rate as the body begins to protect its energy reserves. This biological adaptation may actually make long-term weight loss more difficult, and it can also cause other health problems such as gallstones.
3. Emotional and cognitive effects
Hypoglycemia can significantly affect a person's emotional state and cognitive performance. Hunger can lead to mood swings, irritability, and difficulty concentrating. Not only does this affect an individual's social and professional performance, but it can also have a negative impact on relationships.
4. Increased risk of eating disorders
Falling asleep hungry at night for long periods of time can lead to overeating during the day, increasing cravings for unhealthy foods, creating a vicious cycle. This eating pattern can lead to eating disorders such as binge eating disorder or anorexia in the long run.
5. Nutritional deficiencies
Skipping or eating less at night can lead to an overall nutrient intake, especially for those who need extra nutrients, such as pregnant women, older adults, and athletes. Nutritional deficiencies can lead to weakened immunity, loss of muscle mass, and long-term health problems.
