During sleep, the brain repeatedly cycles through distinct stages of REM and non-REM sleep in a specific sequence. REM sleep stands for rapid eye movement and is linked with dreams and the body’s reactions and responses to the dreams. Non-REM sleep, on the other hand, stands for non-rapid eye movement and consists of three phases of sleep, from getting drowsy to the period of deep sleep that is needed by an individual to gain the energy for the coming day.
REM sleep lasts for about 90 minutes to 2 hours. You may have intense dreams during REM sleep because your brain is more active. Your muscles get temporarily paralyzed, so you generally do not move during typical REM.
The three stages of non-REM sleep last for about 5-15 minutes each.
- Stage 1: Even with your eyes closed, you are easy to wake up since you are not in a deep sleep.
- Stage 2: Your heart rate starts slowing down, and the body temperature drops. The body is getting ready to go into a deep sleep but is still in a light sleep condition.
- Stage 3: This is a deep sleep stage. It is hard for you to wake up on your own when you’re in this stage. If someone wakes you up, you can fall asleep within a few minutes. During this stage, your muscles start healing; hence this is an essential part of your sleep. After this stage, you slowly divulge into REM sleep and start dreaming.
What are the causes of REM sleep?
According to research, the neural pathways in the brain supposed to prevent muscles from moving are active while dreaming in REM sleep. This inhibits your body, legs, or arms from moving, i.e., result in temporary paralysis. In some cases, the neural pathways and the chemical that keeps your body still don’t serve their purpose. As a result, you might develop disorders like sleepwalking or sleep behavior disorder (RBD).

Medication can most often treat REM sleep behavior disorder successfully in most cases. One of the most effectively used medicines suggested and used for this condition is Clonazepam.

Once you mark any such physical or vocal response while asleep, on a regular basis, seek help from your doctor. Some precautions you can take to have safe sleep are:
- Remove the sharp or expensive objects from your bedside. Objects such as weapons or valuable watches, cell phones have to be removed from near you.

- Sleep a little away from your partner if you notice them being hurt by your movements during sleep.
- Maintain a standard sleep pattern. Make a sleep timetable and make sure you follow it.
You might not get repeated episodes of RBD, but one such episode is enough to scare you about the disorder coming your way. It is your body, and you are responsible for taking care of it. Do not neglect any noticeable changes; consult your doctor. REM sleep behavior disorder can be treated easily if you don’t let it increase.
