Health rumors
01
Taking cold medicine can prevent colds.
Truth: taking cold medicine can’t prevent colds. Cold medicine itself can only relieve symptoms. If you want to recover, you still have to rely on autoimmune.
If you don’t have a cold and take cold medicine, especially western medicine to prevent colds, it will not only fail to play a preventive role, but may also bring damage to the body, such as liver function damage.
The best prevention is good living habits: frequent hand washing, frequent ventilation, more exercise, ensuring sleep and balanced diet.
In addition, influenza can be prevented by vaccination, but it should be noted that influenza vaccine can only prevent influenza and has no preventive effect on the common cold.
Health rumors
02
Drinking miscellaneous grains powder is healthier.
Truth: Eat whole grains, and the less you process, the better.
When the whole grains are ground into powder or mashed into rice paste for eating, the whole grains change from large particles to small particles, which is easier to digest and absorb. However, patients with chronic diseases should pay special attention, such as diabetics. Excessive consumption of whole grains powder is likely to lead to a rapid increase in blood sugar.
In addition, because the whole grains contain a small amount of fat, the contact area with oxygen in the air is greatly increased after being pulverized, and it is very easy to be oxidized. If it is not eaten in time, not only the nutritional value will be reduced, but also some substances harmful to health will be produced. It is suggested to eat as much whole grains as possible with less processing.
It should be noted that eating too much coarse grains in the elderly will increase the burden on the stomach, so we should pay attention to the combination of coarse and fine grains, intensive cultivation of coarse grains and ensuring drinking water.

A light diet means eating only vegetarian food and not meat.
Truth: The standard of light diet is less oil, less salt and less sugar.
If you only eat vegetarian food instead of meat, it will increase the risk of malnutrition. For example, if you don’t eat meat, you will be prone to iron deficiency, and then there will be symptoms such as iron deficiency anemia, muscle attenuation, osteoporosis and memory loss.
Eating only vegetarian food does not make you feel full, and you often take in a lot of extra carbohydrates, which is easy to get diabetes. Therefore, we should selectively eat meat, preferably eggs, milk, soybeans and their products, fish, shrimp and lean meat. These foods can provide the human body with high-quality protein, vitamin A, vitamin B, iron and zinc.
For patients with "three highs", doctors will recommend a light diet, but it does not mean that they are vegetarians. The peeled meat of fish, shrimp and poultry is high in protein and low in fat, which is very suitable for people with "three highs".

Drinking milk before going to bed helps you sleep.
Truth: the effect is minimal, theoretically possible, but the effect of helping sleep is weak.
Although milk white protein in theory contains 5.3% tryptophan, it can synthesize 5- hydroxytryptophan in the body, which is further metabolized into melatonin and participates in sleep regulation.
However, the content of tryptophan in milk is very small, and the content that enters the human body and reaches the brain is even lower, so the effect of helping sleep is weak. A glass of milk is not enough to produce enough "hypnotic hormones".
Drinking milk before going to bed will not only increase the chances of going to the toilet at night, but also increase the burden of digestion, which may be detrimental to sleep.
Health rumors
05
You can catch up on sleep on weekends.
Truth: I usually stay up late, but it is difficult to make up on weekends.
It is one-sided to work overtime and stay up late at ordinary times, hoping to catch up on sleep on weekends.
Long-term sleep deprivation will lead to physical exhaustion, decreased immunity and worse physical fitness. Sleep too long, brain cells can’t get enough oxygen and nutrients, which is why they feel tired when they sleep too much on weekends.
Health rumors
06
Pillows are used for pillow parts.
Truth: Pillows are not only used for the pillow, but also need good support for the neck.
There is a normal physiological lordosis of 10 ~15 degrees in human cervical spine. This lordosis will disappear with lowering the head and increase the head, which is a physiological state.
Under the rhythm of modern life, there are more and more "low-headed people". In the state of bowing, the lordosis will disappear, and the posterior structure of cervical vertebra will be very tired during the day, and it is often in a state of excessive traction. Therefore, when sleeping at night, the pillow should be used to support the neck.
Health rumors
07
Yellow urine means kidney problems.
Truth: There are many reasons for urine yellowing, not necessarily kidney problems.
In our daily life, under normal circumstances, if there are symptoms of yellow urine, we can first consider whether it is because we drink too little water, which leads to urine concentration and excessive internal heat, or because we eat some drugs or food. Then you can drink more water first, and then observe after the urine volume increases. If the urine becomes clear, there will be no problem.
If the urine color continues to change, even blood color, soy sauce color, milky white and black appear, you need to go to the hospital in time to do relevant examinations to clarify the causes of urine discoloration and receive treatment.

Massage of cervical vertebra can cure cervical spondylosis.
Truth: Don’t massage your neck at will.
Cervical spondylosis is a common disease. Although patients will feel more comfortable in a short time with vigorous massage, symptoms will appear again soon, which will aggravate cervical spondylosis.
Improper massage will destroy the stability of cervical spine, accelerate the degeneration and protrusion of intervertebral disc, and make the cervical spinal cord more seriously compressed. If the patient’s neck discomfort has not been relieved, he should go to a regular hospital as soon as possible and not massage at will.
Health rumors
09
The child has a fever, covering his sweat and reducing his fever quickly
Truth: Sweating is more likely to lead to serious illness.
Sweating with a quilt after a cold is not suitable for ordinary people, especially for babies. Because the baby’s limbs have insufficient blood supply and the nervous system development is not perfect, the nerves responsible for managing vasodilation and contraction are prone to disorder. If they are wrapped too tightly, they will not be able to dissipate heat, and dehydration and metabolic acidosis may occur at the same time. More seriously, it will also cause brain hypoxia.
Clinically, there is a special disease for children-"quilt syndrome", which is a serious disease caused by wrapping the baby by mistake. The child is in a fever period, and it is especially important to pay attention to the heat dissipation and not to cover it.

Sleep on a pure hard wooden bed to protect your waist
Truth: Sleeping on a hard bed is not sleeping on a bed board.
Middle-aged and elderly people are not suitable for sleeping on a mattress that is too soft, but sleeping on a hard bed does not mean that people will remove the mattress and put sheets on it to sleep.
Sleeping in a bed with a certain hardness can eliminate the pressure of load and weight on the intervertebral disc and help relieve the symptoms of low back pain. However, if you sleep directly on the hard wooden board, it can’t match the normal curve of the human spine, and the waist can’t be supported, there will be symptoms such as backache and backache. It is suggested that the bed board should be padded with a soft pad of 3 cm to 5 cm.
