Scientists suggest that today, most adults get up to two hours' less sleep than they need.

As a result, those lacking in sleep are forgetful, tired, less productive and grumpy.

Sleep is the time when our bodies and minds are rested and restored.

There are two types of sleep: Rapid Eye Movement and Non-REM.

We need both types to be healthy.

Rapid Eye Movement sleep is when we dream.

Our brains are active, and our eyes have fast short movements, as if watching something.

This type of sleep helps restore our mind.

Non-REM sleep is when our brain and body slow down.

Our heart rate slows and our breathing is regular.

This type of sleep helps restore our body.

We have twice as much Non-REM sleep as Rapid Eye Movement sleep each night.

To get better sleep, have a regular time for sleeping and a routine before you go to bed.

This will give your body the signal that it is time to sleep.

Make sure the bed and bedroom are quiet and comfortable.

If your bed is too hard or too soft, if you are too cold or too hot, you will not sleep well.

For two hours before going to bed do not drink coffee or alcohol, or do not smoke or exercise.

All these activities stimulate your body and make sleep difficult.

Scientists suggest that in the present day, the majority of adults are getting up to two hours less sleep than their optimal requirement.

Consequently, individuals who are sleep-deprived experience memory lapses, fatigue, reduced productivity, and irritability.

Sleep is the period during which our bodies and minds undergo rejuvenation and recovery.

Two categories of sleep exist: Rapid Eye Movement (REM) and Non-REM sleep.

Both forms are essential for maintaining good health.

Rapid Eye Movement sleep corresponds to the dreaming phase.

During this time, our brains remain active, and our eyes exhibit rapid, short movements akin to observing something.

This stage of sleep contributes to the restoration of our mental well-being.

Non-REM sleep involves a slowdown of both our brain and body functions.

Our heart rate decelerates, and our breathing becomes steady.

This type of sleep is crucial for the physical rejuvenation of our bodies.

Each night, we experience twice as much Non-REM sleep as Rapid Eye Movement sleep.

To enhance the quality of your sleep, establish a consistent sleep schedule and pre-sleep routine.

This practice sends a signal to your body that it is time to rest.

Ensure that your sleeping environment is quiet and comfortable.

An excessively firm or soft mattress, as well as being too cold or too hot, can hinder sleep quality.

For the two hours leading up to bedtime, refrain from consuming coffee or alcohol, and avoid smoking or engaging in exercise.

All of these activities stimulate the body and can hinder the ease of falling asleep.

According to scientific findings, a considerable number of adults currently experience a sleep deficit of up to two hours.

This deficiency in sleep leads to cognitive lapses, persistent fatigue, diminished efficiency, and a predisposition toward irritability.

Sleep, a vital phase in which both the body and mind undergo recuperation, plays a pivotal role in our overall well-being.

This phenomenon can be categorized into two distinct phases: Rapid Eye Movement (REM) and Non-REM sleep.

Both of these phases are indispensable for maintaining optimal health.

Rapid Eye Movement sleep is characterized by the occurrence of dreams.

During this phase, cerebral activity remains heightened, accompanied by rapid and fleeting eye movements reminiscent of observational engagement.

The significance of this phase lies in its contribution to the revitalization of mental faculties.

Conversely, Non-REM sleep involves a reduction in the pace of both cerebral and physiological activities.

Heart rate decelerates, and respiration adopts a regular rhythm.

This particular phase assumes a crucial role in the physical rejuvenation of the body.

A striking feature is that Non-REM sleep is experienced twice as much as Rapid Eye Movement sleep during a typical night.

To optimize sleep quality, adopting a consistent sleep schedule and establishing a pre-sleep routine is advisable.

This practice serves to signal the body's internal clock for impending rest.

Creating a serene and comfortable sleeping environment is also imperative.

Inadequate sleep quality can result from a mattress that is excessively rigid or plush, as well as unfavorable ambient temperatures.

In the two-hour window before retiring to bed, it is recommended to abstain from the consumption of coffee or alcohol, and to refrain from smoking or engaging in physical exertion.

These activities tend to invigorate the body, impeding the natural process of falling asleep.
