Staying up late to watch dramas and play games has become the norm for most young people. But our bodies are not fighters after all, and there will always be times when we can't stand it in the dead of night.
I'll answer first: Yes!
Although staying up late can affect the body's natural biological clock and digestive system, resulting in reduced digestion and absorption capacity. But if you feel like you're about to "power out" when you stay up late and need to recharge to continue working or studying, then eating a late-night snack is also okay.
But pay attention to the time and intake of late-night snacks, it is not recommended to do it for a long time, otherwise the body may be seriously damaged.
All the food we eat must be digested through the stomach. Under normal circumstances, the stomach wall repairs itself at night, but eating dinner for a long time will increase the burden on the stomach and intestines. Not only will the stomach lining not be repaired, it will continue to be stimulated. Over time, it is easy to cause flatulence, gastric mucosal erosions, peptic ulcers, and even pancreatitis in severe cases.
For dinner, most people will choose seafood, barbecue, fried noodles and other foods with high salt and oil. But at night, the body's metabolism slows down, and some friends like to go to bed after dinner, so that fat is more likely to accumulate in the liver and induce fatty liver.
In addition, most of these foods have high purine content, especially friends who love to drink, which not only causes alcoholic fatty liver, but also easily causes gout due to elevated uric acid.
Long-term eating high-fat, high-salt foods will also increase blood lipids and blood cholesterol in the body, stimulate the liver to produce more low-density lipoprotein known as "bad protein", and increase the risk of disease. Coronary heart disease, impotence and other diseases.
If we don't stop when we eat dinner, if we accidentally eat too much, the intestines, liver, gallbladder, pancreas and other organs will start to function again, and the brain will also be excited, resulting in insomnia.
The stomach is a true workaholic, 24 hours a day, and when we eat, it secretes stomach acid to digest food. But after the food is emptied, stomach acid is still secreted. If hunger (fasting) is more than 10 hours, the stomach is prone to "reflux" stomach acid, causing stomach problems.
Not only that, but our brains need blood sugar to function properly. When the blood sugar supply is insufficient, the central nervous system function of neurons in the brain is disturbed, affecting cognitive function and sleep. If we are in a state of hunger for a long time, there is no source of blood sugar in the body, and the liver glycogen reserves in the body are limited, our body will be in a state of internal and external troubles, resulting in hypoglycemia. This may result in coma.
For many "overtime dogs and test preparers" who can't help themselves, pay attention to the following points when eating late-night snacks at night:
Dinner should not be later than 18:00 to 20:00, so that the time of late night snack can be staggered (generally more than 2 hours from dinner), so that the stomach has enough time to digest food, and it is best to rest 1 to 2 hours before going to bed after the last dinner to avoid the risk of gastroesophageal reflux.
Try not to eat high-fat, high-oil, irritating foods for dinner, which are not only difficult to digest, but also easy to increase the risk of cardiovascular disease.
You can choose easy-to-digest and light foods such as soup, wontons, noodles, dumplings, porridge, etc., to reduce the burden on the stomach.
For a good sleep quality, you can also choose foods rich in tryptophan and vitamins, such as millet porridge, milk, eggs, oatmeal, etc. Because tryptophan produces melatonin to promote sleep, while vitamins help relieve anxiety and get the body to sleep as quickly as possible.
Whether it is dinner or late-night snack, chew slowly and control the amount of food. In general, it is enough to eat until 70% full, which helps the stomach and intestines to digest quickly.
