How Sleep Works and Why the Quality of our Sleep Matters?

Sleeping well makes us feel better, more alert, energetic, and better able to concentrate and perform our daily tasks. Getting enough sleep each day is one of the most important things you can do for your health and wellbeing and to reduce your risk for ill-health.

Why Sleep is Important

It is well known that sleep is an important biological function essential for life. While we sleep many important functions take place that help the body in physical recovery and repair, support brain development, cardiac function and body metabolism, as well as support learning, improving memory and mood. Sleep is especially important for children playing an important role in growth and overall health and babies and children need much more sleep than adults.

Without enough sleep we are more likely to have problems with thinking, concentration, memory, reaction times and mood, all of which make it harder to perform our daily tasks and increase the risks of mistakes and accidents. Regular insufficient or poor sleep contributes to long-term health problems such as;

  • Obesity
  • Type 2 diabetes
  • Cardiovascular disease
  • Poor mental health.

How Sleep Works

Sleep is a state of reduced consciousness, but one which we can be easily wakened. When we sleep our brains remain active, although activity levels vary throughout the course of sleep along with other physiological functions, such as body temperature, breathing and heart rate.

Sleep Drive and our Body Clock 

Our sleep is controlled by two interacting systems:

  • Homeostatic sleep drive processes that balance out time awake with periods of sleep. In other words, when we have been awake for a long period, this process ensures we feel sleepy and helps us sleep long enough to make up for the time we are awake.
  • Body Clock is the name often used to refer to Circadian Rhythms. Circadian rhythms are created by our central nervous system and control a lot of our biological processes such as sleep, as well as body temperature, and hormone activity. Our circadian rhythms are also synchronized with the 24-hour cycle of light and dark resulting in our normal pattern of night-time sleep.

If our circadian rhythms are disrupted it can interfere with our sleep. For example, Jet Lag occurs when our circadian rhythms are disrupted by long-distance flying.

Sleep cycles 

Sleep is divided into different periods of light and deep sleep across the night. These occur in cycles of about 90 minutes. Each cycle includes periods of non-REM sleep, ranging from light to deep sleep, and REM (Rapid Eye Movement) sleep when our brains are more active and dreams occur. 

Sleep cycles are different for older and younger people. Sleep cycles can be affected by a number of things such as disruption to your body clock (circadian rhythms), too much day-time napping, stress, exercise or too much exposure to bright light prior to usual bed time.

what affects our sleep?

There are several factors that can interfere with healthy sleep at night. These factors can both defined as external or internal. Knowing these factors in detail can certainly help you eliminate some of them from your daily life.

External factors that affect your sleep:

  • Lighting: Our body clock gets adjusted according to the changes we observe in our environment. Therefore, it automatically starts to wind down as the brightness levels start to decrease. Bright lights can trick the body clock to assume that it is still day. This makes the body clock to delay sleep timing.
  • Sleep environment: Environmental factors can affect your sleep. These include the feeling of safety at the place of your sleep, and how comfortable the bed is. Most people find it difficult to fall asleep, when they move to, or visit a new place.
  • Jetlag: As earlier explained, the body clock might suffer if there are changes in exposure to light to the eyes. Jetlag also has the same effect on the body. It takes time to adjust to different time zones, thus disturbing our sleep timings.
  • Shift-based work: Shift-based work affects the sleep quality the same way as jetlag. This is because the body clock is not able to work properly. Variations in the sleep timings every other week or month confuses the body’s clock, and this results in bad sleep.

Medication: Many chemicals like such as caffeine and nicotine disturb sleep quality. Many medications like anti-depressants also have some chemicals which interfere with the healthy course of sleeping.

Internal factors that affect your sleep:

  • Body aches or other pains: Certain pains like muscle or joint pain, or even headaches can keep you awake at night. These conditions bring discomfort to a person, which makes it difficult to fall or remain asleep for long.
  • Anxiety or stress: Our bodies are built in such a manner that they respond to stressful or dangerous situations by remaining awake. The same happens during stress, depression, or anxiety, where the person finds it difficult to get a complete sleep at night. Most of the time in such cases, a person gets more REM sleep than deep sleep.

    what if you composed a catchier title? I ain’t saying your content is not good, however what if you added something to
    possibly grab folk’s attention? I mean How Sleep Works and Why the Quality
    of our Sleep Matters? is a little plain. You might
    peek at Yahoo’s front page and watch how they create news titles to get viewers to open the links.

    You might add a related video or a related picture or two to grab readers
    interested about everything’ve got to say.
    In my opinion, it might make your website a little bit
    more interesting.
