Motion sickness is feeling dizzy and having the urge to vomit. Other symptoms include having cold sweats, loss of appetite, increase in saliva production, pale skin, headaches, weakness, and shallow breathing, It is caused by having conflicts regarding the senses.
For instance, when you are on a roller coaster, your eyes see the calm sky but your muscles feel the tension of the speed, and your inner ears, which sense balance, get confused with the changing states of gravity and balance. Such differing information disorients the brain. Motion sickness may be prevented or addressed by taking deep breaths and focusing on a stable object or the horizon, avoiding alcohol, eating light, and avoiding reading or watching, eating ginger or mint, and taking medications. This is more common among pregnant women and children.
