What is Deep Sleep?
So what is deep sleep? Well, the simplest answer is that it is one of the stages in the sleeping process. This stage is also known as slow wave sleep, delta sleep and more recently, N3. Deep sleep is a time when repairs take place within the body and energy is restored for the day ahead. This stage of sleep plays an important role in maintaining your health as it boosts the immune system, stimulates growth and repairs any damage to tissue and muscles.
Deep sleep also has a number of benefits, including:
- It can help in keeping your heart healthy. During deep sleep, your heartbeat slows down and gives your heart the opportunity to repair itself.
- Lack of deep sleep can trigger the production of cortisol and adrenaline which increases blood pressure. Deep sleep allows your body to rest and slows down your heartbeat, thereby lowering blood pressure.
- During deep sleep, the brain repairs itself and the body produces hormones as well as neurotransmitters that help in promoting new brain cell production. This brain repair prevents different mental disorders.
- By maintaining healthy brain function, deep sleep can significantly help in preventing memory loss and disorders such as Alzheimer’s disease.
- When you are in the deep sleep stage, the protein inside your body repairs damage caused by free radicals, microorganisms and other factors like harmful substances and toxins.
Apart from this, deep sleep helps in improving digestion, preventing diabetes, fighting inflammation, alleviating stress and anxiety, preventing obesity, promoting healthy weight, restoring energy, enhancing immunity and more.
