Understand Sleep: Science, Stages, and Better Sleep Tips

Sleep maintains our physical and mental health. It allows our bodies to repair and restore. It also helps us function correctly throughout the day. However, many people need help to get enough sleep. 

Sometimes, sleeplessness occurs due to stress or a temporary ailment. It is common and goes away quickly. However, in some cases, sleep loss turns into chronic insomnia, a matter of grave concern.

Chronic insomnia is a severe health complication that affects people around the world. A research study by the National Center for Biological Information states 33% overall prevalence of sleeplessness in adults. The risk increases with age and underlying health conditions like diabetes.

Today, we will explore the science of sleep, its stages, why dreams happen, and factors that affect sleep quality. We will also discuss ways to improve sleep.

Why Do We Sleep?

We sleep to keep our brain functions intact. We need sleep to process things and do daily chores effectively. The vital functions sleep serves in our body include;

Restoration

Sleep allows our bodies to repair and restore themselves. It will enable our body to improve damaged cells and tissues.

Conservation of energy

Sleep helps us to conserve energy. When we sleep, our bodies slow their metabolism and use less energy. As a result, more energy is preserved, and we can use it to do essential tasks.

Brain function and cognitive maintenance

Sleep is essential for brain function and mental care. While we sleep, our body releases toxins for the body. It helps us to think clearly and learn new things.

Mood regulation

Sleep also plays a role in mood regulation. Sleeplessness initiates negative emotions such as depression and anxiety.

The Stages of Sleep

Sleep is not a uniform state. It has certain stages. The four stages of sleep involve the following;

NREM1 (Non-Rapid Eye Movement 1)

This is the initial stage of sleep. Our brains remain active in this stage. We can quickly awake by slight disturbance.

NREM2 (Non-Rapid Eye Movement 2)

The second and more profound stage than NREM1. In this stage, our perceptions slow down, and our muscles relax.

NREM3 (Non-Rapid Eye Movement 3)

It is the deepest stage of sleep. Our brain waves prolong, making it difficult to wake up during this stage.

REM (Rapid Eye Movement)

Dreams occur during the fourth and last stage of sleep. Our eyes rush, and our brain activity is similar to when we are awake.

Dreams

We can’t understand dreams as they are complex phenomena. However, scientists believe that dreams may serve several functions, including:

Processing emotions

Dreams may help us to process feelings that we are experiencing during the day.

Problem-solving

Dreams may help us to solve problems that we are facing.

Creative thinking

Dreams may stimulate creative thinking and problem-solving.

The Importance of Sleep Hygiene

Sleep hygiene is an excellent practice to support healthy and high-quality sleep. Good sleep hygiene is essential for having restorative sleep. Here are some critical suggestions for healthy sleep hygiene;

Set a Peaceful Sleep Environment

Before going to bed, establish a calming routine. Have a soothing bath, or do gentle stretches. These activities help to prepare your mind and body for sleep.

Optimize Your Sleep Environment

Your bedroom should be calm, dark, and quiet. You can use earplugs to cut off surrounding noises if needed.

Consistent Sleep Routine

To improve your sleep, stick to a regular sleep schedule. It means going to bed and waking up simultaneously every day. Doing so helps regulate your body’s internal clock.

Avoid Alcohol Before Bed

On the one hand, alcohol makes you sleep faster. On the other hand, it reduces deep restorative sleep later at night. Hence, avoid using it before bedtime.

Limit Screen Time

The light from electronic devices like phones, TVs, and computers affects sleep by reducing melatonin production. Put your devices at bay an hour before bedtime to get the best sleep.

Exercise Regularly

Moderate activity during the day helps promote deep sleep at night. However, avoid doing exercise close to bedtime.

Manage Stress

Anxiety and over-thinking make falling and staying asleep harder. Try relaxing activities before bed to calm both mind and body.

Prioritize sleep hygiene and stick to healthy sleep habits. It will give you the advantage of better sleep and improved health.

Troubleshooting Common Sleep Problems

Many people regularly deal with sleep difficulties. Here are some common sleep problems and tips to overcome sleep problems:

Insomnia

Cognitive behavioral therapy helps with racing thoughts. Before bed, restrict electronics, follow a routine, and ensure that you optimize your bedroom for sleep.

Sleep Apnea

This condition causes breathing interruptions during sleep. See a doctor for potential diagnosis and treatment options like CPAP (continuous positive airway pressure) therapy.

Restless Leg Syndrome

Uncomfortable leg sensations disrupt sleep. Iron supplements, magnesium, and hot baths before bed can help in mild cases.

Nighttime Bathroom Trips

Limited fluid intake before bedtime prevents frequent bathroom visits during the night. See your doctor to rule out more significant medical issues.

Anxiety and Stress

Relaxation techniques, therapy, and stress management help quiet racing thoughts at night.

Chronic Pain

Work with your doctor to optimize pain management and sleep positioning. Heat, massage, or acupuncture can also help.
