none. Benzodiazepines decrease slow wave (stage 3 and 4) sleep and only mildly suppress REM sleep. however, no benzodiazepines increase REM sleep.
A piece of non-medical, anecdotal evidence to the contrary: I use the Zeo sleep clock to track my REM, deep and light sleep in minutes every night as I have pretty bad insomnia. After days of very little REM (under an hour) I took one xanax .25mg at bedtime, then another at 3:00a.m.-same dosage- and got 1 hour, 56 minutes of REM sleep. I haven't repeated b/c I don't want to become dependent, and it could have just alleviated anxiety and allowed me to catch up on a REM deficit. But it certainly didn't seem to suppress REM either.
REM sleep is amazing sleep!
REM rebound involves the tendency for REM sleep to increase following REM sleep deprivation.
REM (Rapid Eye Movement) sleep is active sleep.
3/13/2012 jhh: REM sleep is NOT deep sleep. In fact, it is the lightest stage of sleep. In order from awake to deep sleep: AWAKE, REM, LIGHT, DEEP. Deep sleep and REM sleep are the most important stages though. Light sleep doesn't do much for you. Deep replenishes your body, while REM replenishes your mind. Older answer (not accurate): Yes. It is the deeper form of sleep that we experience during our sleep cycle, rem sleep is where dreaming occurs But not the deepest sleep, which would be delta. That's where, unless your a mother and hear your baby cry, you are oblivious to your environment.
Yes blind peole have REM sleep!!
There are 4 non-REM stages and REM sleep.
You will know when someone is in REM sleep when there eyes-lids are moving really fast back and forward. REM sleep is a sleep that is after your first 4 stages of sleep and is the stage of sleep that you dream.
The percentage of time spent in REM for an infant of 1-15 days is about 50% and 3-5 months: 40% and 6-23 months: 30%. The percentage continually decreases as age increases, but many adults tend to keep themselves in REM sleep for about 20-25% of sleep. Again the older people are the less they are in REM sleep and older adults from the ages of 70-85 may drop the amount of time in REM below 20%.
