Dreams can occur at any time during sleep. However, you can have the most vivid dreams at a stage called REM sleep, when the brain is most active. Some experts say we dream at least 4-6 times at night. Lucid dreaming is a dream that you know you are dreaming about.

Sleep is an that allows your body and mind to recharge, leaving you refreshed and alert when you wake up. Healthy sleep also helps the body remain healthy and stave off diseases. Without enough sleep, the brain cannot function properly. This can to concentrate, think clearly, and process memories.

Most adults require between of nightly sleep. Children and teenagers need substantially more sleep, particularly if they are younger than five years of age. Work schedules, day-to-day stressors, a disruptive bedroom environment, and medical conditions can all prevent us from receiving enough sleep. A healthy diet and positive lifestyle habits can help ensure an adequate amount of sleep each night - but for some, chronic lack of sleep may be the first sign of a sleep disorder.

The Science Behind Sleep

An regulates your sleep cycle, controlling when you feel tired and ready for bed or refreshed and alert. This clock operates on a 24-hour cycle known as the circadian rhythm. After waking up from sleep, you'll become increasingly tired throughout the day. These feelings will peak in the evening leading up to bedtime.

This sleep drive - also known as sleep-wake homeostasis - may be linked to adenosine, an organic compound produced in the brain. Adenosine levels increase throughout the day as you become more tired, and then the body breaks down this compound during sleep.

Light also influences the circadian rhythm. The brain contains a special region of nerve cells known as the hypothalamus, and a cluster of cells in the hypothalamus called the suprachiasmatic nucleus, which processes signals when the eyes are exposed to natural or artificial light. These signals help the brain determine whether it is day or night.

As natural light disappears in the evening, the body will release melatonin, a hormone that induces drowsiness. When the sun rises in the morning, the body will release the hormone known as cortisol that promotes energy and alertness.

Stages of Sleep

Once we fall asleep, our bodies follow a sleep cycle divided into four stages. The first three stages are known as non-rapid eye movement (NREM) sleep, and the final stage is known as rapid eye movement (REM) sleep.

Stage 1 NREM: This first stage marks the transition between wakefulness and sleep, and consists of light sleep. Muscles relax and your heart rate, breathing, and eye movements begin to slow down, as do your brain waves, which are more active when you are awake. Stage 1 typically lasts several minutes.

Stage 2 NREM: This second NREM sleep stage is characterized by deeper sleep as your heart rate and breathing rates continue slowing down and the muscles become more relaxed. Eye movements will cease and your body temperature will decrease. Apart from some brief moments of higher frequency electrical activity, brain waves also remain slow. Stage 2 is typically the longest of the four sleep stages.

Stage 3 NREM: This stage plays an important role in making you feel refreshed and alert the next day. Heartbeat, breathing, and brain wave activity all reach their lowest levels, and the muscles are as relaxed as they will be. This stage will be longer at first and decrease in duration throughout the night.

memory consolidation National Center for Biotechnology Information The National Center for Biotechnology Information advances science and health by providing access to biomedical and genomic information. REM: The first REM stage will occur about 90 minutes after you fall asleep. As the name suggests, your eyes will move back and forth rather quickly under your eyelids. Breathing rate, heart rate, and blood pressure will begin to increase. Dreaming will typically occur during REM sleep, and your arms and legs will become paralyzed - it's believed this is intended to prevent you from physically acting out on your dreams. The duration of each REM sleep cycle increases as the night progresses. Numerous studies have also linked REM sleep to View Source , the process of converting recently learned experiences into long-term memories. The duration of the REM stage will decrease as you age, causing you to spend more time in the NREM stages.

These four stages will repeat cyclically throughout the night until you wake up. For most people, the duration of each cycle will last about . NREM sleep constitutes about 75% to 80% of each cycle. You may also wake up briefly during the night but not remember the next day. These episodes are known as "W" stages.

How Much Sleep Do Humans Need?

The right amount of sleep largely depends on your age. The National Sleep Foundation recommends the following daily sleep allotment for different age groups.

The Importance of Getting Enough Sleep

For most adults, at least seven hours of sleep each night is needed for proper cognitive and behavioral functions. An insufficient amount of sleep can lead to serious repercussions. Some studies have shown sleep deprivation leaves people vulnerable to attention lapses, reduced cognition, delayed reactions, and mood shifts.

It's also been suggested that people can develop a sort of tolerance to chronic sleep deprivation. Even though their brains and bodies struggle due to lack of sleep, they may not be aware of their own deficiencies because less sleep feels normal to them. Additionally, lack of sleep has been linked to a higher risk for certain diseases and medical conditions. These include obesity, type 2 diabetes, high blood pressure, heart disease, stroke, poor mental health, and early death.

Adults who do not receive a sufficient amount of sleep each night can implement some positive lifestyle and sleep habits in order to log the needed seven to nine hours. These include the following:

Establish a realistic bedtime and stick to it every night, even on the weekends.

Maintain comfortable temperature settings and low light levels in your bedroom.

Keep a comfortable sleep environment by ensuring you have the best mattress, best pillows, and best sheets for your sleep preferences and body type.

Consider a "screen ban" on televisions, computers and tablets, cell phones, and other electronic devices in your bedroom.

Abstain from caffeine, alcohol, and large meals in the hours leading up to bedtime.

Refrain from using tobacco at any time of day or night.

Exercise during the day; this can help you wind down in the evening and prepare for sleep.

Why Do We Need Sleep? | Sleep Foundation

# data[].attributes.attachment_link.description
We tend to think of sleep as a time when the mind and body shut down. But this is not the case; sleep is an active period in which a lot of important processing, restoration, and strengthening occurs. Exactly how this happens and why our bodies are programmed for such a long period of slumber is still somewhat of a mystery.

# data[].attributes.body
The purpose of dreams is that dreams save important memories and lessons, remove unimportant memories, and help organize complex thoughts and feelings. Studies show that sleep helps maintain memory.
