The Science of Sleep: Why You Should Pay Attention to the Quality of Your Sleep

Sleep is very important when it comes to the general well being of a human being. Unfortunately, proper attention is seldom given to it in our day to day activities. Some patients suffer from sleep disorders while the rest disregard the need for enough sleep even though this doesn’t exploit them. They must also embrace the science behind the sleep cycle and how it bears an impact on their health to make decisions on their sleeping patterns that will ultimately enhance their well being. The following post explains how the sleeping process works at the physiological and mental levels, and what can be done to improve the quality of our sleep.

 

Understanding Sleep: The Basics

Sleep Stages and Cycles:

Sleep cannot be viewed as a homogeneous stage but rather it has different stages that are rotated during one night. These stages comprise of sleep can be broadly viewed as two types including Non-Rapid Eye Movement (NREM) and Rapid Eye Movement (REM).

 

NREM Sleep:

Stage 1: This stage is the first part of sleeping and it is also considered as drowsiness which takes place between the state of absolute wakefulness and deep sleep. It usually lasts for a few minutes during which the brain and muscles become inactive at some degree as brainwave activity slows down.

Stage 2: It is a light sleep but deeper than stage 1 where the heart rate decreases and the body temperature reduces. This is also very important for the restoration processes both physical and mental.

Stage 3: Restorative sleep also known as deep sleep or slow wave sleep this stage is very important in recovery from the day’s activities and also growing. It is this stage where the tissues in the body’s cells are repaired and body immunity increased which makes it the most recuperative.

 REM Sleep:

REM sleep is marked by quick eye movements, high brain activity and dreaming. It is essential for several cognitive abilities such as remembering, learning and regulating emotions. After a person has fallen asleep which may be about 90 minutes, they will enter REM stage and it will progressively get longer through the night. 

Sleep Cycles: 

Simply put, people sleep in cycles that last for around 90 minutes twenty times during the night. Each of the cycles consists of NREM and REM sleep stages. Approximately 4 to 6 complete cycles per night revolve in a day’s sleep. For deep and REM sleep cycles plenty of every stage for the required time within the boundaries of a day is a necessity.

The Relationship between Sleep and Health

1. Cardiovascular Health: 

Cardiovascular health is one among many things that are preserved by appropriate sleeping hours. Consecutive lack of adequate sleep has been associated with the risk factors of hypertension, heart attacks, and cerebrovascular accidents. The heart rate and blood pressure go down considerably during the deep sleep state, thus providing rest and repair to the heartbeat and the blood vessels.

2. Immune Function:

The role of sleep in the body is basic in improving defense mechanisms. The body synthesizes and releases proteins called cytokines which are important during sleep and serve to fight off both infections and inflammation. Without enough sleep, the immune reaction to infections is compromised, which increases the chances of getting the illness and the recovery duration.

3. Weight Management:

Sleep has deep effects on managing people’s weights. Inadequate rest disturbs the equilibrium of hormones that control the feelings of hunger, consequently increasing the yearning to eat high qualicucalorie foods. Lack of sleep alters the responses to insulin hence leading to an increase risk to prenatal obesity and stress disorders.

 

4. Metabolism and Hormonal Balance:

Different metabolic processes and hormonal balances are modulated by sleep. To illustrate this, the bulk of growth hormone which is crucial for metabolism and muscle recovery among other things is secreted during deep sleep. Thus, those with sleeping disorders have a tendency toward elevated levels of cortisol and ghrelin which impact stress and appetite respectively.

 

The Effect of Sleep on Mental Health

1. Cognitive Function:

This is where sleep plays a core role as supports cognitive function like: memory consolidation, problem solving and decision making. REM in particular, aids in the retention of short term memories to long term memories and also helps in the improvement of skills which require high level and creative problem solving. Lack of sleep also results in poor performance of cognitive tasks and learning and generally shrinking of the attention span.

2. Emotional Regulation:

Unsurprisingly, sleep affects emotion regulation. In the absence of sleep one may with heightened emotionality, sudden mood changes and increased stress. There are also reports that relationships between sleep deprivation and anxiety, depression and other related disorders are significant. Several studies suggest that REM sleep provides protection against anxiety promoting thoughts and emotions.

3. Mental Health Disorders:

In addition, chronic sleep disorders, remaining as the most serious and pervasive syndrome have vicious connections to a variety of mental disorders. Insomnia, for instance, aggravates depression as well as anxiety and bipolar disorders in patients. There is generally an importance of targeting sleep dysfunction in the management of these illnesses.

 

Strategies for Increasing Quality of Sleep

1. Go To Bed Regularly:

Following a regular sleep pattern assists in the adjustment of the body’s internal circadian rhythm clock and thus enabling an individual to fall asleep and wake up naturally. For instance, refrain from waking up on days such as weekends then enforcing sleeping schedules that tend to be restrictive for the weekday.

2. Make the Sleeping Area Relaxed:

Critical aspects when it comes to sleep include the strife environment. For instance, the best controlled conditions consist of a dark cool and quiet bedroom. There is also a need to make sure that the bed, mattress, and pillow used are well suited for the position of sleep. Blackouts and earplugs can be augmented with foam earplugs and soft earcup style headphones out of concern for discomfort for some individuals.

3. Try Not to Use Electronics Before Going to Bed:

Providing exposure of screens for an extended period of time, especially short before bedtime is known to promote disruption to sleep as these devices emit blue light which decreases melatonin hormone production that is useful for sleep. For example, it is recommended that all electronics should be shut down for at least an hour before bedtime to avoid engaging with screens.

4. Employ Relaxation Techniques:

Before bed, include relaxation exercises and calm practice because it is time for your body to rest. Cuddling up, moving, employing relaxing activities such as progressive muscle relaxation or simple deep breath exercises may ease you into sleep.

5. Restrict Consumption of Stimulants and Heavy Foods: 

Caffeine and even the more provocative nicotine if taken too late may make sleeping difficulty. Even more, heavy and spicy food should be avoided as this may cause discomfort and other related issues leading to detrimental sleep. Make it a rule for yourself especially in the evenings not to take such substances as caffeine and other similar drugs-in fact, even large meals.

6. Undertake regular physical activities: 

Studies have shown that even mild levels of physical activity may be enough to impact sleep positively or assist the individual to regain better sleep cycles, not for the next day but those sleep depredation activities of the sleeping hours concerned. Such activities for example include brisk walking, climbing stairs, or making the beds. On the contrary, improvise activities an hour before the sleep schedule as intense activities will complicate the process of getting to bed. 

7. Take care of stress:

It is important to highlight that increased stress levels are bad for sleeping patterns. Forgetting or neglecting stress-management techniques will only make things worse and certain activities especially how you go about your day will prove rather impossible.

 

Addressing Sleep Disorders: Finally Focusing on Sleeping Disorders

1. Insomnia:

Insomnia is often described as the inability to fall asleep, difficulty staying asleep or excessive waking up too early. It can be managed through appropriate insomnia psychotherapy (CBT-I), drugs or modification of some behaviors. If one thinks he or she has insomnia, it is advisable to see a qualified medical professional and get appropriate assistance.

2. Sleep Apnea: 

Sleep apnea is the condition when a person’s breathing during sleep gets interrupted for several times. The common symptoms are loud snoring, choking or gasping during sleep, and daytime sleepiness. It can be treated with behavioral modifications, use of CPAP or other procedures. The person might have to go through a sleep study for diagnosis.

3. Restless Legs Syndrome (RLS): 

RLS occurs when a person has unpleasant feelings in the legs and has to keep moving them especially at night before the person goes to bed. There are no curative drugs for this disorder only compensating mechanisms.
