If you have health insurance with your employer then quit, how can you get new health insurance with your new employer because aren’t they going to see all your pre-existing history from your old insurance company?

Best answer:

Answer by Johnny Friendly
If you get join your new employer’s health plan, they can’t exclude pre-existing conditions if it’s a group plan. They have to accept everybody. If you obtain any kind of health insurance within 60 days after leaving your job, by law the insurance company can’t deny coverage of pre-existing conditions.

Question by Rachelle: What happens to your mind/body during REM sleep?
I know that REM stands for rapid eye movement and that REM sleep is a deep, dream-filled sleep. But what else? When does REM sleep begin? What happens to your mind/body during this sleep cycle? What happens if it is interrupted?

What Is REM Sleep?
Usually, REM sleep occurs 90 minutes after sleep onset. The first period of REM typically lasts 10 minutes, with each recurring REM stage lengthening, and the final one may last up to an hour. Polysomnograms show brainwave patterns in REM to be similar to that recorded during wakefulness. In people without sleep disorders, heart rate and respiration speed up and become erratic during REM sleep. During this stage the eyes move rapidly in different directions.

What Happens During Sleep?
Sleep is prompted by natural cycles of activity in the brain and consists of two basic states: rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep, which consists of Stages 1 through 4.

During sleep, the body cycles between non-REM and REM sleep. Typically, people begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep. Dreams generally occur in the REM stage of sleep. Then the cycle repeats all over again.

During the deep stages of NREM sleep, the body repairs and regenerates tissues, builds bone and muscle, and appears to strengthen the immune system. As you get older, you sleep more lightly and get less deep sleep. Aging is also associated with shorter time spans of sleep, although studies show the amount of sleep needed doesn’t appear to diminish with age

Intense dreaming occurs during REM sleep as a result of heightened brain activity, but paralysis occurs simultaneously in the major voluntary muscle groups. REM is a mixture of encephalic (brain) states of excitement and muscular immobility. For this reason, it is sometimes called paradoxical sleep.

The percentage of REM sleep is highest during infancy and early childhood. During adolescence and young adulthood, the percentage of REM sleep declines. Infants can spend up to 50% of their sleep in the REM stage of sleep, whereas adults spend only about 20% in REM.

Most dreaming takes place during REM (Rapid Eye Movement) sleep. Periodic eyelid fluttering, muscle paralysis, and irregular breathing, body temperature, heart rate, and blood pressure distinguish REM from non-REM sleep stages. REM sleep is also called “paradoxical” sleep because brain wave activity is similar to an awakened state. It is during REM sleep that the brain blocks signals to the muscles to remain immobile so dreams will not be acted out. Adults spend about 20 – 25% of their sleep cycle in REM sleep.

The EEG activity during REM sleep shows mixed frequency and low voltage with occasional bursts of “sawtooth” waves. Compare this EEG pattern with the wakefulness pattern

How Much Sleep Do You Need?
The amount of sleep a person needs depends on the individual. The need for sleep depends on various factors, one of which is age. Infants usually require about 16-18 hours of sleep per day, while teenagers need about 9 hours per day on average. Most adults need about 7-8 hours of sleep per day.

The amount of sleep a person needs also increases if he or she has been deprived of sleep. People do not seem to adapt to getting less sleep than they need.

What Are the Consequences of Too Little Sleep?

Too little sleep may cause:

Impaired memory and thought processes.
Decreased immune response.
Sleep deprivation also magnifies alcohols effects on the body, so a fatigued person who drinks will become much more impaired than someone who is well-rested. Sleep deprivation also increases pain perception on pain simulation testing. Caffeine and other stimulants can temporarily overcome the effects of severe sleep deprivation, but cannot do so for extended periods of time.

When you sleep, your body rests and restores its energy levels. However, sleep is an active state that affects both your physical and mental well-being. A good night’s sleep is often the best way to help you cope with stress, solve problems, or recover from illness.

So constant interrruption of REM sleep sleep or QUALITY sleep will result in daytime fatigue; premature aging, stress and a depressed immune system.; can make one cranky, irritable and have headaches and difficulty in concentration.
