How can you resist without eating. Without eating but drinking water regularly, according to observations made on voluntary fasts, you can stand one to two months. It also depends a lot on physical activity practicing. Many ascetics, for example, resist as long as they remain almost motionless for days.
How much you can withstand the cold. The optimum body temperature is less than 37 C. Below 35 C the body begins to suffer from hypothermia, a condition that becomes lethal when the body touches the 24 C. This value can be achieved if, for example, it falls into the sea and the water temperature is below 10 C.
How can you resist the noise. The considered critical threshold to avoid hearing damage is 90 decibels, that of around 120 decibels pain. Sounds of 185 - 200 decibels can even kill the man: he believes in fact that would cause fatal air embolism. At this intensity you come close to a plane taking off.
How can you resist without going to the bathroom. It depends on supply, ingested by the fibers, the lifestyle, physical activity. According to experts, an asset is when a regular is around 3-4 times weekly. In extreme cases, such as for astronauts who have a diet lacking in fiber, you can also be evacuated only once a month.
How much you can resist heat. If the body temperature exceeds 42 C, our organism is likely hyperthermia (fever and damage to the nervous system). It happens when the ambient temperature reaches 60 C and the humidity is very high, which does not allow us to expel the excess heat sweating.
How can you resist the altitude. Already at altitudes of around 4,500 meters the human body is in danger, because the oxygen starts to get low. Going even further you will get to what is called Death Zone (8,000 meters), where only trained physical, and often equipped with cylinders, they can survive for short periods.
How much you can survive without oxygen. The lack of oxygen supply to tissues leads to death in about 3-4 minutes. The first cells to die are those brain. In some conditions, such as a profound hypothermia (particularly low temperature), the body very lowers metabolism and can withstand several more minutes.
How much you can resist the acceleration. A man can not bear positive acceleration of 5g (ie 5 times the acceleration of gravity) with no damage, but only for a few seconds. The higher the g and the time when you are undergoing, the blood returns to the legs and the brain remains without blood and without oxygen.
How much can you survive without sleep. Sleep deprivation, according to scholars, impairs our well-being to harm job performance and interpersonal relations and especially the brain functioning. If prolonged, it causes severe mental changes which, after about 10 days, can cause death.
How can you resist without drinking. Lack of water causes dehydration, a condition that is fatal to the body after about 10 days. Without water, in fact, the blood becomes thicker and so are compromised cardiac activity, renal and that of many other essential to life.
