Deep sleep is the stage of sleep in which the slowest brain waves are active. Hence, this period of the sleep is also referred to as slow-waves sleep. During this time, the brain waves have a relatively higher amplitude with a frequency lesser than 1 HZ. In case you do not get deep sleep, chances are that you could be suffering from conditions such as sleep apnea or other disorders. In this regard, reach out to sleep apnea doctors right away!
What is the importance of deep sleep?
Well, you might be wondering that why is deep sleep so important after all. Well, deep sleep is important as it allows consolidation of memories. Hence, it is also known as ‘sleep dependent memory processing’. This is the prime reason why people who are suffering from insomnia have a very6 poor memory. As a result of this, they are not able to complete memory based tasks as easily as other people.
With slow-wave sleep, declarative memory also gets improved. This includes both episodic and semantic memory. A central model exists, which is based on an assumption that the long term memory storage occurs due to an interaction between neocortical and hippocampal networks.
The prime function of deep sleep
According to the sleep deprivation studies conducted on test subjects, it has been revealed that the prime function and purpose of deep sleep is to allow the brain to have more time to restore itself from all the activeness. When there are tasks being performed that need mental activity, the brain produces more glucose metabolism.
The growth hormone is also secreted during deep sleep. This is why, it is extremely important for children in the growing age to sleep enough. During this time, it is observed that the body is unable to wake up from sound that is of a particular volume. Though, this may differ among individuals. While some people will wake up from very small sounds, others will have a difficulty waking up no matter how loud the sound is.
After waking up from a slow wave sleep, it is normal for people to feel groggy. According to cognitive tests, awakening from deep sleep can impair the mental cognitive performance for up to 30 minutes. In comparison, waking up from other stages allows a person to become more active quickly. This phenomenon is referred to as sleep inertia by the doctors.
How to increase slow-wave deep sleep
There are a number of things that you can do to increase your slow-wave deep sleep. Body heating and exercise are considered to be one of the most common ways of increasing slow-wave sleep. This is why having a hot shower before sleeping is considered to be very relaxing and therapeutic. At the same time, it is important to consume a diet that is low on carbohydrates before going to sleep. This allows sleepers to increase their percentage of deeper sleep.
The lower fat content in a diet that lacks carbohydrates can be quite helpful and keeping the body asleep. However, this certainly does not mean that you have to cut out all fats and carbohydrates from your diet.
In case nothing seems to be working for you, reach out to a sleep center Rockville right away and voice all your concerns out. There, you are likely to find a doctor who will specialize in your particular problem. Based on your case, a doctor will be able to give you the best advice that you could ever receive. This way, ultimately, you may be able to get rid of any sleep disorder and fall asleep easily.
