Like you, many people must be wondering whether it is a dream or a problem. Let us tell you today why such a jolt is felt in sleep.
what is the meaning of jerking in sleep
These jerks in sleep are called hypnic jerks in the medical term. Hypnic jerk myoclonus means that these jerks of sleep come in that part of the brain where the startle process of the brain is controlled. There is no single reason for hypnic jerk, there can be many reasons behind it. Actually, during sleep, the body goes into complete rest mode. At this time the muscles rest and the heart rate also slows down. During this, the brain tries to check whether the heart is working properly or not and because of this, it stimulates the hypnic jerk. Apart from this, when the muscles go into rest mode, the brain feels as if we are really falling and in such a situation, hypnic jerks come in to recover. To put it in simple language, the body sleeps at this time and the brain is completely awake and it shocks the body on seeing any kind of emergency.
Stress and caffeine can also be the reason
People who drink more tea and coffee or do more exercise and workouts are more prone to hypnic jerks in sleep. Apart from this, emotional stress or lack of sleep can also be the reason for this. Many times we are in such a deep sleep that every part of the body except the brain goes into rest mode, so the brain shocks the body considering it lifeless whether it is alive or not. Although it is a normal process to happen, but if you are having frequent sleep tremors, then you must definitely get a checkup done by a doctor.
