Why Is Deep Sleep Important? While all stages of sleep are necessary for good health, deep sleep offers specific physical and mental benefits. During deep sleep, your body releases growth hormone and works to build and repair muscles, bones, and tissue. Deep sleep also promotes immune system functioning.
Deep sleep is important for your physical and mental health, and has many benefits, including:
Brain health
Deep sleep helps with brain restoration, which can help you feel refreshed in the morning. It also helps with memory consolidation and formation, and may play a role in language learning and motor skills.
Physical health
Deep sleep helps your body repair and build muscles, bones, and tissue. It also helps regulate hormones, including growth hormone and prolactin. Growth hormone helps with growth and metabolism, while prolactin is important for breast growth and lactation.
Immune system
Deep sleep helps strengthen your immune system by supporting hormonal shifts that help your body respond to disease.
Waste removal
Deep sleep may help remove waste products from your brain, including those that can lead to dementia.
Energy
Deep sleep helps replenish your energy stores. Elite athletes value deep sleep for this reason.
The amount of deep sleep you get decreases with age. People under 30 may get two hours of deep sleep each night, while people over 65 may only get 30 minutes or none at all.
To improve your sleep, you can try:
Establishing a bedtime schedule
Getting enough exercise
Avoiding caffeine, alcohol, and nicotine
Creating a bedtime routine
Banishing bright lights and loud noises from your bedroom

And is there any way to break the cycle? Dan Kwartler details the science of insomnia.
