It's essential to get enough sleep and and the deep sleep stage is particularly beneficial.
So what exactly is deep sleep?
Deep sleep is one of the stages that we go through on a nightly basis. It is usually the third stage of the sleep cycle.
It's an NREM (non-rapid eye movement) stage which is sometimes referred to as slow-wave sleep as your brain waves slow down. Deep sleep allows your body and mind to recharge and is the stage when your body is completely relaxed.
During the deep sleep stage, your body will experience some changes. Your heart rate and breathing will slow down, and your muscles will relax. Your brain waves also slow down during deeper stages of the sleep cycle.
Deep sleep generally takes place for more extended periods in the first half of your sleep cycle. The first deep sleep will last between 45 and 90 minutes. You'll then go into other phases of the sleep cycle before going back into a deep sleep. Each time this happens, the deep sleep phase will get shorter until it eventually stops.
So why is deep sleep important?
Deep sleep provides many physiological and physical benefits. It can help you to is process information and improves your mood.
A lack of deep sleep will leave you feeling fatigued, and you'll be less likely to remember things. This is because your brain won't effectively convert information into memory.
People who don't get adequate deep sleep are more likely to develop Alzheimer's disease as they age. Those who suffer from sleep disorders and don't get enough deep sleep are more prone to severe medical conditions such as obesity, diabetes, and heart disease. A lack of deep sleep can even shorten your life expectancy!
Deep Sleep Repairs Your Tissues
Studies have also shown that having enough deep sleep can affect how you look, and feel. If you want to have younger and healthier looking skin, then deep sleep is a phase that's incredibly important.
This is because deep sleep is the most restorative time of the night. During deep sleep, your body will repair itself, and cells have time to recover. Your energy will also be restored during deep sleep, allowing you to wake feeling refreshed and ready for another day.
During the deep sleep phase, the pituitary gland will secrete crucial hormones into your body. These hormones help the body to grow and develop. It's crucial for teenagers who are going through puberty to get enough deep sleep.
As deep sleep causes your brain activity to decrease, the blood that would usually be sent to your brain is instead sent to your muscles. This helps your body to repair tissues, heal muscular issues and maintain the immune and nervous systems.
Deep sleep is vital as it can affect the quality of your life.
And If you're often waking up feeling tired or groggy in the morning, likely, you're not getting enough deep sleep.
