Many people attach great importance to their health, walking for exercise, getting up in the morning with a glass of light salt water, drinking tea for health...
It sounds like it's healthy, but you know what? Keep these 5 "good habits" sticking and your body may be getting worse and worse.
01
How good is it to walk 10,000 steps a day?
Some people pay too much attention to the number of steps when walking, must walk 10,000 steps, 20,000 steps, or compete with others, no matter how many steps are taken, how long they walk, in short, they must walk more than others.
Right thing to do:
● 2-hour principle: No matter what kind of exercise, after the exercise, the knee pain lasts for more than 2 hours, which means that the exercise is excessive and the amount of exercise needs to be reduced.
● Step by step: exercise can not be eaten into a fat person, according to their physical condition, slowly, can not come up with a particularly large amount of exercise, easy to cause harm to the body.
02
Wake up in the morning with a glass of light salt water
Laxative and detoxifying?
Light salt water does not laxate nor detoxify, drinking light salt water on an empty stomach in the morning can not only promote bowel movements, but also may pose a threat to our health, after a night's rest, human blood is in a concentrated state when you get up in the morning.
At this time, if you ingest light saline, it may further increase blood concentration, which can easily lead to physical discomfort.
Moreover, in our country, some people's own salt intake is over the standard, in the case of no lack of salt in the body, if you drink light salt water, it will increase the intake of salt, but make people feel dry mouth.
If you are suffering from high blood pressure, cardiovascular and cerebrovascular diseases, and abnormal kidney function, you can not use light salt water as the first glass of water after getting up.
Especially for patients with high blood pressure, 6:00~10:00 in the morning is one of the peak times for blood pressure, if drinking salt water will increase blood pressure.
Right thing to do:
Boiled water is the best choice for the first glass of water in the morning, drinking amount is about 200ml is appropriate, the water temperature is best 20 °C ~ 40 °C, too hot water will increase the risk of esophageal cancer, drink water to take a sip slowly.
03
Start cooking and turn on the range hood
Save money and be healthy?
Everyone knows to turn on the oil pumping machine when stir-frying, but many people habitually turn on the range hood synchronously when stir-frying, feeling that this saves money and will not cause harm to the body.
This approach is actually not scientific enough.
When stir-frying, if in a closed kitchen environment, high-temperature frying and other cooking methods, PM2.5 air pollution test values average close to 800ug/m³, and this data has reached the level of pollution that can be achieved around the human body by lighting 1 cigarette.
Short-term inhalation of oil fumes can have strong irritation to the mouth, nose, eyes and mucous membranes, and long-term inhalation is the culprit of lung cancer.
Moreover, the time to smoke a cigarette is only 1 minute ~ 2 minutes, but more than 60% of women are exposed to oil smoke in the kitchen for a long time, at least one hour a day.
Therefore, some people call "stir-fry for 1 hour, smoking 40", which is not alarmist and needs attention.
Right thing to do:
1. Promote the use of healthier methods such as steaming, boiling and stewing to replace frying, stir-frying, cooking and frying, and avoid repeated cooking and frying;
2. The purchase of range hood should be considered from the aspects of air volume (determine the speed of exhaust smoke), wind pressure (ability to resist suction), and environmental noise;
3. The range hood is recommended to be "opened early and closed at night", and the waste oil in the oil storage box should be thrown out in time;
4. Clean the range hood pipes and filter regularly.
04
Is it good for the stomach to eat while it is hot?
Many people will feel that greedy for cold hurts the stomach, and the cooked meals and brewed hot tea must be eaten and drunk while hot to warm the stomach, and the stomach will be healthier.
However, regular consumption of particularly hot foods can be a health hazard, such as hot drinks or foods above 65°C or 65°C to increase the risk of esophageal cancer.
Because overheated and hot food in the esophagus will cause physical damage to the esophageal mucosa, when the mucosa is damaged, gastric acid reflux will also cause irritation to the injury site.
This repeated damage can easily lead to cell cancer, and the risk of esophageal cancer will increase.
Right thing to do:
The appropriate temperature for eating is neither cold nor hot, you can let the meal dry for 10 minutes before eating, or you can use your lips to test the temperature before eating.
05
Drinking tea is good for the body
Is it better to drink strong tea?
Tea contains a lot of tea polyphenols, which are antioxidants that can resist oxidation, anti-inflammatory, and also change blood viscosity.
Reduce blood lipids, make blood vessel elasticity better, prevent microvascular rupture, long-term drinking can make the heart and blood vessels healthier, reduce blood lipids, prevent cardiovascular diseases.
The stronger the tea, the more beneficial?
Wrong! Tea is not the stronger the better, some people may be two-thirds of a cup of tea is tea, only a small amount of water, which is easy to cause heart discomfort, because tea also contains caffeine, theophylline and so on.
At the same time, if you drink a lot of strong tea, the tannic acid in it will react with the iron in the food to form new substances that are difficult to dissolve, which will hinder the absorption of iron.
Right thing to do:
The higher content of tea polyphenols in green tea can reduce the risk of cardiovascular and cerebrovascular diseases in women by slightly more;
Oolong tea reduces the risk of cardiovascular and cerebrovascular diseases for men; Consistent tea drinking in older adults can indeed reduce the risk of death from cardiovascular disease by a large percentage.
To achieve the role of preventing cardiovascular and cerebrovascular diseases, drink at least 3 cups ~ 4 cups a day, 220 ml ~ 230 ml per cup, drink at least 4 ~ 5 times a week, do not be greedy, do what you can, and drink tea continuously every day.
Note: Drinking tea can not replace the effect of drugs, just a way to assist our body to be healthier, if there are cardiovascular and cerebrovascular diseases or to find a specialist doctor in the hospital for treatment.
