what is motion sickness?

               what is motion sickness?

 If you can enjoy amusement park ridesand winding roads,without feeling sick then you are very lucky because about one-third people don't feel very  well these situation.You must have seen some people around or even some of you who often feel nauseous in anus,road or airplane.This problem is faced by animals too,in some cases.
                 Even though it is a common problem scientists have been unable to zero in on a single cause.But most accepted theory point to the imbalance between our eyes and ears as the cause So,when we are sitting in a moving car Our eyes tell our brain that we are sitting in one place and at rest on the other side our ears tell our brain that we are running

                                                                                   


Wait a second! our ears? YES Our ears perform another function,besides listing in our ears is a sensory system  in our ears is a sensory system called Vestibule System it contains fluid which when we move contributes to the sense of balance & spatial orientation this system tells your brain of slightest of movement Whether you are moving forward of backwards slow or fast it even tells the brain about the angle our body is in So,when sitting in a moving car your vestibule system tells the brain that you are running at the speed of the car Ware your

eyes do not corroborate this And more so if you are reading a book a total opposite can happen as well Like if you are seeing  a movie which have frantic camera movements like virtual reality videos in which eyes see that your on mountains or
 on a joy ride in these in these situations  your ears say you are at rest but your eyes single to the brain that the body is moving.This causes confusion it is believes that this confusion is the cause of issue.Even if we believe this theory  what explains our throwing up? How does this confusion cause that?Scientists are not really sure about this as well but some have answer for this.Fast moving cars,joy rides and VR movies are relatively new.Before these,there were not a lot of things that caused such confusion Except on thing poison Since poison is harmful for the body our body
has a way of getting rid of it by vomiting. This theory explains the cause to some extent but there are still some unanswered questions Like why only some people get motion sick?Why is more common in women than men?Why being a passenger causes it more that being a driver?and so on..According to a study,genetics could play a role as well Some people feel this imbalance in senses more than other are more sensitive to this and get sick more than others A driver sees the winding turns more than other there fore their senses are relatively less confused Some reports even say that experiencing the situation multiple times you get motion sick less often like pilots,sailors,astronauts get better at tracking it with experience  Astronauts?  astronauts are launched in space at a speed of about 27000 km/h
motion sickness is a big problem and finding solutions to this problem and finding solutions to this problem is one of NASA's task Even after much research we can't confidently point to a cause but do have some tips to avoid it from happening like seeing out of your car's window so that eyes can see the motion as well Chewing a gum Eating some specific medicines ETC.... But even these tips are not fool proof and this question tells us then even after much progress and research we still have so much to know about our body

What is fever

what is fever? We get it because of climate (probably mean weather) change. We get fever due to cold weather. We hang out in winter, eat ice cream. This is the body's natural defense mechanism. To fight the disease, your blood will start circulating, which increases the body temperature. So we all have fever at some point or the other. But before you take your medications... and think about taking Paracetamol or Cronin , let's understand what a fever is and why do we get it? Even though the outside temperature changes from time to time, but the internal temperature of our body remains fairly constant. Our internal body temperature remains around 37 °C or 98.6 °F. But sometimes this internal temperature rises by a few degrees. We feel cold, shiver and feel sick. It is usually caused by a high temperature (fever) infection. But diseases like cancer, heat stroke etc can also cause fever. In this we will not discuss those reasons. Therefore, whenever we feel...
