Understanding Sleep Cycles
Sleep is structured into cycles, each lasting about 90 minutes. These cycles progress through four stages: the first two are light sleep, followed by deep sleep, and finally REM sleep. Each stage plays a distinct role in maintaining health and well-being.
The Significance of Deep Sleep
Deep sleep, also known as slow-wave sleep, is vital for physical recovery and growth. During this stage, the body repairs tissue, builds bone and muscle, and strengthens the immune system. Missing out on deep sleep can lead to feelings of fatigue and impaired cognitive function.
Why REM Sleep Matters
REM sleep is essential for psychological health, as it is linked to dreaming and cognitive processes like memory and learning. An adequate amount of REM sleep contributes to better mood regulation and creativity.
Effects of Poor Sleep on Health
Poor sleep can have damaging effects on both physical and mental health. Common issues include increased stress levels, memory problems, and a higher risk of chronic conditions such as obesity and heart disease.
How to Improve Your Sleep Hygiene
