The Science Behind Sleep: Why You Need 7-8 Hours
Introduction
Sleep is an essential part of life, and getting enough of it is crucial for our physical and mental health. Most adults need about 7-8 hours of sleep per night, but many of us are not getting enough. This can lead to a variety of health problems, including obesity, heart disease, and diabetes.
The Stages of Sleep
Sleep is not a uniform state. We actually go through a series of different stages of sleep throughout the night.
- Stage 1: N1 - This is the lightest stage of sleep. We are still relatively aware of our surroundings and can be easily awakened.
- Stage 2: N2 - This stage is a bit deeper than Stage 1. We are less aware of our surroundings and it is more difficult to wake us up.
- Stage 3: N3 - This is the deepest stage of sleep. We are completely unaware of our surroundings and it is very difficult to wake us up.
- REM sleep - REM sleep is characterized by rapid eye movements. This is the stage of sleep in which we dream.
The Benefits of Sleep
Getting enough sleep has a number of benefits for our physical and mental health. These benefits include:
- Improved mood
- Increased energy levels
- Improved cognitive function
- Reduced risk of obesity, heart disease, and diabetes
- Stronger immune system
