The force of gravity is the weakest at the equator because of the centrifugal force caused by the Earth's rotation and because points on the equator are furthest from the center of the Earth. The force of gravity varies with latitude and increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles.
Also, pharmacological therapies such as sedative-hypnotics or antidepressants have been helpful in reducing the incidence of sleepwalking in some people. Sleepwalking is common in children and is usually outgrown over time, especially as the amount of deep sleep decreases.
Some sleeping pills have potentially harmful side effects, including parasomnias. Parasomnias are movements, behaviors and actions over which you have no control, like sleepwalking. During a parasomnia, you are asleep and unaware of what is happening. Parasomnias with sleeping pills are complex sleep behaviors and may include sleep eating, making phone calls, or having sex while in a sleep state. Sleep driving, which is driving while not fully awake, is another serious sleeping pill side effect.
