As the pace of modern life accelerates, more and more people are staying up late. In the quiet of the night, it's a "golden time" for many: to create in peace, to study, or to gather with friends for a good time... However, it's important to know that regularly staying up late is an unscientific lifestyle that can easily disrupt your biological clock, leading to high energy at night and lethargy during the day. Over time, many people find it difficult to return to their original rhythm and may experience symptoms like constipation, gastric ulcers, and depression. Want to adjust your biological clock and try to be more of a "morning person"? This is actually not that difficult.
Staying up late can easily lead to the following major harms:
Skin Damage
Generally, the skin enters its evening maintenance state between 10 and 11 PM. If you stay up late for extended periods, the normal circulation of your endocrine and nervous systems will be disrupted, causing problems like dryness, loss of elasticity, and a dull complexion. Endocrine imbalance can also lead to issues like acne, pimples, chloasma, and dark spots, especially on the skin of young people.
Tips: Before staying up late, be sure to remove your makeup or wash your face to prevent a thick layer of powder or oil from causing breakouts under the stress of being awake. After staying up late, wash your face with alternating cold and warm water to stimulate blood circulation. It's best to apply a mask and massage for 5 minutes to rehydrate your skin.
Decreased Immunity
Among the various damages staying up late can cause to the body, the most common is frequent fatigue and listlessness, which leads to a decline in physical resistance. For people with weaker immunity, respiratory diseases like the common cold and gastrointestinal problems can also become more common.
Tips: Resolutely resist "unnecessary late nights" and establish a regular sleep schedule. If you have to work late, take breaks in between. Also, pay attention to nutritional supplementation.
Memory Decline
Normally, a person's sympathetic nervous system should rest at night and be active during the day to support daily work and life. However, for those who stay up late, the sympathetic nervous system becomes active at night. This can lead to daytime symptoms like drowsiness, dizziness, memory loss, lack of concentration, slow reactions, forgetfulness, and headaches. Over time, this can also lead to neurasthenia and insomnia.
Tips: If you have to work late, limit it to a maximum of 1-2 times per week. Additionally, night shift workers should get adequate rest during the day and not schedule other activities. Eating more meat, fish, and dairy products can enhance memory.
Yin Deficiency and Excessive Fire
For those who stay up late, the body is working beyond its capacity, which can easily lead to functional disorders. In Traditional Chinese Medicine, this is known as "yin deficiency with excessive fire," or what people commonly call "internal heat." Furthermore, the lives of people who stay up late are often irregular. To stay up, some people eat larger dinners, so late-nighters often have stomach and intestinal problems.
Tips: You can improve this through dietary therapy to protect your gastrointestinal health.
Vision Decline
Extended overuse of the eyes can also cause pain, dryness, and a feeling of pressure in the eyes, and may even lead to dry eye syndrome. Fatigue in the eye muscles can also cause temporary vision loss. If you frequently stay up late and overwork, you might also develop central serous chorioretinopathy, which can cause blurred vision, a dark spot in the center of your field of view, distorted or shrunken objects, and changes in color perception. Vision can also drop sharply, with a minimum decrease to 0.1.
Tips: It is recommended to rest for about 10 minutes every 40 minutes, or 15 minutes every hour. You can look into the distance, do eye exercises, and take a moderate amount of Vitamin A. Vitamin A helps regulate retinal light-sensitive substances, improving the adaptability of people working late to dim light and preventing visual fatigue. Vitamin A and Vitamin B2 are also effective in preventing vision deterioration. It is recommended to eat more foods rich in Vitamin A, such as carrots, chives, and eel, and foods rich in Vitamin B, such as lean meat, fish, and pork liver.
A few suggestions for those who frequently stay up late:
Increasing Nutrition is Key
Eat more nutrient-rich foods like milk, eggs, lean meat, and soy products. Have light, palatable, and soft meals, and supplement with foods rich in Vitamin A, such as animal liver, egg yolks, and roe. Eat more fruit or fresh juice. It is also beneficial to take a moderate amount of multivitamin supplements under a doctor's guidance.
Prioritize Making Up for Sleep
People who often stay up late tend to sleep during the day, especially for those who have to work night shifts. However, daytime sleep is often affected by sunlight, noise, etc., which can increase fatigue and even lead to loss of appetite, anxiety, and irritability. Therefore, after staying up late, you should rest promptly and not push yourself to work non-stop. Even if you feel energetic, you should replenish your sleep in a timely manner. It is recommended to take a nap after lunch to help restore physical strength.
Exercise is Essential
If you feel tired or drowsy while staying up late, it's best to rest适时; don't force yourself to keep going. If you can't rest due to work requirements, don't rely on coffee, strong tea, or cigarettes to stay awake, as caffeine can stimulate the brain to secrete excitatory substances, which can easily lead to insomnia and increase blood lipid levels, harming cardiovascular health. It's best to do some simple activities on the spot, such as slow原地 walking, practicing Tai Chi, massaging your temples, or doing simple stretching exercises for your limbs and neck.
Special Reminder:
Irregular late nights are worse than regular ones
Staying up late is a chronic hazard to one's health, especially for white-collar workers who have intermittent (irregular) late nights. Frequently adjusting the biological clock is particularly harmful to their health. Therefore, Western labor protection experts have once called for night shift workers to be relatively fixed within the same group of people.
People who stay up late for long periods are more susceptible to cancer
This is because cancer cells are produced during cell division, and cell division mostly occurs during sleep. Staying up late disrupts the regular sleep pattern, affecting normal cell division, which can lead to cell mutations and the production of cancer cells.
