As the saying goes, health is the foundation of everything. Only when you are healthy can you have a good appetite.

But with so much health information circulating, it's hard to distinguish truth from falsehood. Falling for a scam is a minor issue compared to damaging your health – that would be a much bigger loss.

Where can we get reliable health information?

Actually, I have a lot of health tips that I've always wanted to share with everyone. Today, I'll start with 28 tips from pediatrics, ophthalmology, gynecology, urology, emergency medicine, and dermatology!

What the pediatrician wants to say

1. Babies under 1 year old do not need to eat salt.

For babies under 1 year old, the sodium naturally present in their food is sufficient to meet their needs, so there is no need to add extra salt.

The good habit of eating less salt should be instilled in babies from a young age.

2. Xiao Chai Hu injection is contraindicated in children.

Bupleurum injection, used as an antipyretic injection, was once widely used in the treatment of fever in children.

However, the National Medical Products Administration has found that it poses a huge potential hazard, and may even lead to death, and has banned its use for children.

3. Babies under 1 year old do not need to use a pillow.

Babies under 1 year old do not have a fully developed cervical spine and do not need to use a pillow when sleeping.

Using the wrong pillow can actually increase the risk of Sudden Infant Death Syndrome (SIDS).

4. If your baby has a fever, do not bundle them up to sweat it out.

When a baby has a fever, covering them too much can hinder heat dissipation and cooling down, and their body temperature may rise even higher, potentially even triggering seizures.

The temperature should be comfortable; don't try to make yourself sweat unnecessarily.

5. Compound cold medicines are not recommended for children under 4 years old.

Compound cold medicines generally contain multiple active ingredients and lack dosage standards for children, which can easily lead to overdose in babies.

It is not recommended, especially for children under 4 years old.

What the ophthalmologist wants to say

6. Make sure to protect your eyes from the sun.

Ultraviolet rays can directly penetrate the fundus of the eye, increasing the risk of diseases such as cataracts, pterygium, and macular degeneration.

Wearing sunglasses not only looks cool, but it also protects your eyes—a win-win situation.

7. Looking at green does not relieve eye strain.

It's said that looking at green is good for the eyes, so many people have changed their computer screens to green.

Actually, as long as you keep staring at things up close, your eyes are working hard, and it won't matter if everything around you is green.

8. Do not use eye drops indiscriminately.

Eye drops have a cool, refreshing feel and are very soothing when applied. However, long-term use may lead to eye damage due to the preservatives and cooling ingredients they contain.

The most important thing to protect your eyes is to rest them, and not to rely on eye drops for a quick "relief".

What a gynecologist wants to say

9. Ovarian massage was ineffective.

The ovaries are located deep in the lower abdomen. A normal-sized ovary cannot be felt from the outside of the abdomen, so it is impossible to improve ovarian function.

The "technicians" at the beauty salon were just pretending to massage my stomach.

10. It's not true that washing makes you healthier.

Using various gynecological washes can disrupt the vaginal flora balance, making things worse. If you must wash, just use plain water.

11. Menstruation does not necessarily refer to "menstruation".

The average menstrual cycle is 28 days, but if it occurs regularly every 21 to 35 days, it is also considered normal. Don't worry if your menstrual cycle is a little longer.

12. Women should begin regular cervical cancer screenings from age 21.

Most cervical cancers can be diagnosed early through screening. The main screening methods are cervical smears and HPV testing.

The cervical cancer vaccine does not cover all HPV subtypes, so screening is still necessary even if you have been vaccinated.

What a urologist wants to say

13. Frequent urination does not necessarily indicate kidney problems.

Urine volume can vary depending on factors such as water intake and sweating; drinking more water will naturally increase urine volume.

More often than not, poor kidney function manifests as reduced urination.

14. Kegel exercises can improve urinary incontinence.

The pelvic floor muscles support organs such as the uterus, bladder, small intestine, and rectum; you can feel them when you contract your anus.

Kegel exercises can strengthen the pelvic floor muscles, improve urinary incontinence, and also help improve the quality of life for couples. They are beneficial for men, women, and children of all ages.

15. Wipe from front to back after using the toilet.

For women, the urethra, vagina, and anus have progressively higher defenses against pathogens from front to back.

Whether you've defecated or urinated, always wipe from front to back after using the toilet to reduce the risk of infection. This is especially important for women; make sure you wipe in the correct direction!

What a gastroenterologist wants to say

16. The most crucial thing for nourishing your stomach is to develop good habits.

For a stomach-soothing diet, instead of just drinking porridge and eating steamed buns, it's better to cultivate good habits:

Eat regularly;

Don't wolf down your food;

Drink less alcohol and smoke less;

Eat less of the foods your stomach doesn't like;

Eat less pickled and heavily seasoned foods;

Wash your hands thoroughly before meals and after using the toilet.

17. People with a preference for strong flavors have a higher risk of stomach cancer.

Countries with a high incidence of stomach cancer share this characteristic: they eat a lot of salty food.

The latest version of the "Dietary Guidelines for Chinese Residents" recommends that healthy adults consume no more than 6 grams of salt per day.

18. Don't rely on laxative teas to solve constipation.

Many laxative teas contain stimulant laxatives, and long-term use may cause electrolyte imbalances such as melanosis coli and hypokalemia, so they should not be the first choice for relieving constipation.

19. People over 50 years of age should ideally have a colonoscopy to screen for colorectal cancer.

Colorectal cancer is one of the five most common cancers in my country, and colonoscopy is an effective way to detect it. It is recommended that people over 50 years of age have a colonoscopy every 5 to 10 years.

Early detection and early treatment can nip cancer in the bud.

What the emergency doctor wants to say

20. If you get burned, don't apply anything indiscriminately.

After a burn, just remember:

Rinse thoroughly with plenty of cool water;

Remove the clothing from the wound;

Continue to soak the burned area in cold water;

Cover the wound with a clean towel or gauze and secure it.

If the burn is severe, go to the hospital as soon as possible.

Applying toothpaste, soy sauce, lard... nothing works after a burn.

21. Do not apply heat after a sprain.

After a sprain, the first thing to do is rest, and then apply a cold compress promptly.

Within 48 hours, you can apply an ice pack wrapped in a towel or chilled mineral water to the sprained area. After 48 hours, you can apply heat.

22. If someone faints, do not pinch their philtrum.

Pinching the philtrum (the area between the nose and upper lip) is nothing magical; it can't cure diseases, it's just a way to check a patient's consciousness. Simply put—if someone is awake, they'll wake up without pinching; if they're not awake, pinching won't help.

23. When treating wounds, do not use gentian violet.

Gentian violet is often used for superficial skin abrasions, but studies have found that it has some potential carcinogenicity.

For wound treatment, it is recommended to use iodine tincture or povidone-iodine. If the wound is serious, it is best to have it treated by a doctor.

What a dermatologist wants to say

24. Don't use face masks every day.

Using too many face masks or leaving them on for too long can cause excessive hydration of the stratum corneum, leading to damage to the stratum corneum, thinning of the skin, and impaired barrier function, which is actually bad for the skin.

Using the same products that celebrities use every day not only doesn't help with skincare, but it also wastes your money.

25. Don't forget sunscreen on cloudy or rainy days.

On seemingly cloudy or rainy days without sunshine, the ultraviolet radiation intensity can actually reach about 70% of that on sunny days.

Don't be lazy just because it's cloudy or rainy and there's no sunshine. Always keep sun protection in mind.

26. Eating more collagen won't make you more beautiful.

Collagen is ingested and broken down before it can be absorbed; it cannot be directly converted into collagen in the skin.

To improve your skin, cleansing, moisturizing, and sun protection are the foundation.

27. Avoid using skincare products that promise rapid whitening.

No legitimate product can "whiten skin quickly".

Some unregulated skincare products often illegally add substances such as hormones and mercury to achieve rapid whitening effects. However, prolonged use can easily lead to problems such as hormone-dependent dermatitis or heavy metal poisoning.

28. Don't use cotton pads to apply toner.

Using cotton pads to apply toner is not only wasteful, but the constant friction from the cotton pads on the face can also damage the normal stratum corneum.

For toner, simply apply it evenly with your hands.

When it comes to health, every little detail matters. Listen to your doctor, don't panic when problems arise, and don't be fooled by scammers. Hopefully, these reliable health tips will help you and those around you.
