2, it is easy to shout high. Most people will have altitude sickness when they reach an area above 3000 meters. If you yell at the plateau at this time, it will speed up the breathing rate and increase the consumption of oxygen, which is prone to altitude sickness such as dizziness. In addition, brisk walking, running or heavy physical labor will aggravate the high reaction.
3, running fart is a healthy performance. It's easy to fart when running, but it's normal. Because after eating, people will produce more gas due to the action of digestive tract flora. These gases move downward with the peristalsis of the intestine and are discharged from the anus. When running, people will speed up metabolism and promote intestinal peristalsis, so the probability of farting is higher than usual.
4, sports drinks can not be drunk. After exercise, many people have the habit of drinking sports drinks. But what we don't know is that if the exercise doesn't reach the basic amount, the intake of sports drinks will increase the burden on the kidneys.
Sports drinks are mainly used to replenish electrolytes for the human body. However, when there is not a lot of sweating after exercise, drinking sports drinks will increase the burden on the body because of excessive electrolyte intake, bring extra burden to the kidneys, and may cause edema and hypertension.
This kind of food is mainly high in calories. Outdoor travel, everything is simple, chocolate, beef jerky, bread and other high-calorie foods can quickly replenish the energy needed by the body. The pressure of outdoor is to be full.
6. You can't take a bath immediately after exercise. After the exercise, I felt sticky and wanted to rush to the bathroom at once. After taking a shower, the fatigue and dust on my body are washed away, which makes people feel very relaxed.
But this practice is unscientific. During exercise, the blood flow to muscles increases, and this situation will continue for some time after stopping exercise. If you take a hot bath at this time, your blood will be insufficient to supply other important organs, such as your heart and brain, and you will feel dizzy, nauseous and weak.
7, foot injury, soaking feet with hot water will aggravate the injury. After a day's walk, my feet are exhausted. It will be very comfortable to soak my feet at this time. However, you should pay attention to soaking your feet with hot water. If you soak your feet with hot water when there is congestion and swelling in your feet, it will make the broken blood vessels bleed more, thus making the condition more serious. At this time, soak your feet in cold water, or cold compress your feet.
8. Outside, fear can kill people. Outdoor, if you feel fear, the original 50% survival hope will be reduced to 30%. When the brain sends out a signal of fear, a large number of hormones to cope with stress are released, which will seriously affect people's vision, cognitive ability and motor control system and reduce your chances of survival.
9. Overweight people are not recommended to run. For every weight increase of 1 kg, the knee needs to bear 3 kg more pressure when walking and 10 kg more pressure when running. So in the case of overweight, hiking will be a better choice.
10, human saliva contains natural painkillers. Human saliva contains a natural painkiller called orphanin, which is six times more effective than morphine. In addition, opioid peptides can have both anti-panic and anti-depression effects.
Don't make a fist when you walk. Many people clench their fists unconsciously when running. But this little gesture will make the muscles of the whole body in a state of semi-tension, making it easier to feel tired and consume physical strength.
12, running won't make your legs thicker. More than 90% marathon runners have thin calves, so don't worry that running will make them thicker, but remember to relax your muscles after exercise.
