17 rules that will save your life
Almost everyone knows that you can not write SMS while driving and what to do in case of fire. But life can throw up such situations to which we do not have a quick and convenient answer. These tips will not be superfluous to save in bookmarks.
The brain cannot simultaneously control the process of walking and using a mobile phone, so look ahead, not at the screen.
Security consultant Murali Krishnan notes that walking and using a phone equally require a lot of cognitive effort. As a result, you can't fully focus on both at the same time, such as walking and chewing. There is a chance to fall victim to "blindness from inattention", when you see an object, but do not realize that it is a car that is driving right at you.
Make sure that the rear-view mirrors in your car are set up correctly, and avoid dead (blind) zones.
A user of the site named Kristen Rush claims that not all cars have a blind spot is inevitable. By adjusting the rear-view mirrors so that you can barely see the edges of your own car, you can successfully get rid of blind spots on the sides. The rear-view mirrors should give you an idea of the position of any car at the back. It's worth spending a few seconds to properly adjust the mirrors when you get behind the wheel.
Heat is transferred faster through a liquid than through a gas, so avoid moisture so as not to freeze.
Engineer Leah Lavoie says that there is a connection between humidity and the feeling of cold. In order not to let the body temperature drop too quickly in cold weather, do not skimp on woolen clothing instead of cotton: it absorbs more moisture, and the dampness does not reach the skin. And of course, do everything possible not to get wet.
There is snow to avoid dehydration, it is possible only in the most extreme cases.
Lavoie also notes that the body uses a huge amount of energy to convert a substance from one state to another. That is why it is worth eating snow as a substitute for water only as a last resort. After receiving this small amount of moisture, your body will spend precious heat.
If your plane has made an emergency landing in the sea, do not inflate the life jacket immediately.
A user named Alvin Yip warns against the urge to immediately inflate a life jacket after the plane made an emergency landing in the sea. The water that can rush into the cabin will complicate the movement if you are wearing a vest. Therefore, first you need to swim to the exit and only then inflate the vest so as not to drown in the sea.
If you choke, then the Heimlich technique can be done to yourself.
Few people realize that you can do without outside help to get rid of a piece of food stuck in your throat. Naman Mitruka told how to do the Heimlich technique on himself. First, you need to fold the leading hand into a fist under the chest directly above the navel. The palm of the second hand should be placed on the fist to press harder. Press your fist into the stomach with a movement inwards and upwards, in the direction of the diaphragm, which is located in the upper part of the abdomen. This must be done with force. Repeat several times until the object stuck in the throat moves and releases the airway.
Always take powerful and proven antihistamines with you when you go to a new place.
You never know where you will come across something that you are allergic to, especially if you are going hiking or camping, notes a user named Ryan Borek.
The limits of the human body are reduced to the "rule of three".
Survival specialists know by heart the short designation of their limits, says Ruchin Agarwal. On average, a person can survive for three minutes without air, three hours without shelter in extreme weather conditions, three days without water and three weeks without food.
If the cooking oil has caught fire, turn off the burner and cover the dishes in which the burning oil is located.
Ruchin Agarwal also explains why you should never use water to extinguish oil or fat that has caught fire. The water molecules sink and end up at the bottom of the hot dishes, instantly evaporate and push the flames even higher. Therefore, the oil that has caught fire should be extinguished by turning off the burner and blocking the access of oxygen to the fire.
If you are injured by a sharp object, do not pull it out of the wound.
If you pull out a sharp object stuck in the body, it will accelerate blood loss, writes Thomas May. Instead, try to cover the wound and do everything possible to stop the bleeding until you receive qualified medical care.
Most plane crashes occur in the first three minutes after takeoff and within eight minutes before landing.
User Sanket Shah writes that aviation safety adheres to the "+3/-8 " rule, which encourages people to be most vigilant immediately after takeoff and immediately before landing — 80% of plane crashes occur exactly then. It is better to use this time to concentrate and remember where the emergency exits are, than to mentally get lost in another movie or audiobook.
Most deaths in domestic fires are due to smoke poisoning, not burns.
User Harsh Sharma advises in this case to bend down closer to the floor in order to inhale as little smoke as possible.
If you are injured in a public place, choose one person and ask for help specifically to him to avoid the effect of an outsider.
Sharma also explains a well-studied psychological phenomenon, because of which crowds of people can not help someone, because everyone thinks that someone else will come to help. If you are not too injured and can call for help, choose one person in the crowd and contact that person directly. This way you are more likely to get help.
A bright lantern can become the best weapon against the aggressor.
Instead of carrying a gas canister or a weapon, it is enough to take a very bright flashlight with you, which will scare off the aggressor no less effectively, says Sanket Shah. "If someone approaches you who seems aggressive to you, in case of danger, a light with a power of 300 or more lumens directed into your eyes (especially at night) will give you the opportunity to hide," the user writes. — And if you misjudged the situation, no one will get hurt and you will avoid trouble."
If you get lost while walking in nature, try to find a fence or a stream.
"A stream of water always flows downhill and inevitably flows into a larger stream or reservoir," recalls user John Mixon. Well, the barrier will definitely lead you to the road or to some building.
Use condoms as a handy water tank.
Condoms are surprisingly elastic. As Janice Batevix notes, you can use this if you suddenly urgently need a large water tank. They can replace a canteen and hold about a gallon of water. "They can also be used for protection from water — as an elastic cover for matches or walkie-talkies on hikes," she advises.
If you look for ways to get out in advance, you will not get lost in case of an emergency.
When local authorities send out warnings about natural disasters to the population, many remain in their places, even when they are strongly advised to evacuate. User John Ewing explains that psychologists call this phenomenon a "deviation of normality". This concerns the tendency of people to believe that everything will be fine, even if they are clearly in danger. Ewing says that a person can get out of the cycle of deviation of normality by determining in advance the location of emergency exits in public places, for example in cinemas or in restaurants. If you mentally prepare for action in a dangerous situation, then you will not get lost.
