Alvás

Alvás is the Hungarian word for sleep. It refers to a natural, recurring state of mind and body characterized by altered consciousness, relatively inhibited sensory activity, reduced muscle activity and inhibition of nearly all voluntary muscles during rapid eye movement (REM) sleep, and reduced interactions with surroundings. Sleep is a fundamental biological process essential for physical and mental restoration, cognitive function, and overall health in humans and many other organisms.

During sleep, the body undergoes various restorative processes. These include the repair of tissues, the consolidation of memories, and the regulation of hormones. Different stages of sleep, primarily non-rapid eye movement (NREM) sleep and REM sleep, are characterized by distinct brain wave patterns and physiological changes. NREM sleep is further divided into stages that vary in depth, while REM sleep is associated with dreaming and increased brain activity.

The amount and quality of sleep required can vary depending on age, lifestyle, and individual needs. Chronic sleep deprivation can lead to a range of negative health consequences, including impaired cognitive performance, weakened immune function, and an increased risk of various diseases. Understanding and prioritizing adequate sleep is crucial for maintaining well-being.
