Sleep Deprivation`s Effect On Health

emotional pain
Much can be said about a good night´s sleep not only does it leave you feeling refreshed and alert, but it allows you to attack your day. It plays a vital role in good health and should not be underestimated.

A good night´s sleep constitutes 7-9 hours per day for adults. (Preschool children need 10-13 hours and school-age children 9-11 hours).

Sleep is vital for brain function and systemic physiology in many body functions. This post takes a deeper look at sleep deprivation’s effects on health.

What is sleep deprivation?

Sleep deprivation effects

Sleep deprivation refers to getting an inadequate amount of sleep. Sleep deprivation can lead to many health problems such as:

  • may increase forgetfulness
  • may reduce the ability to fight off infections (compromised immune system)
  • may increase the risk of acquiring illnesses (cancer, Type 2 diabetes, heart disease, high blood pressure, and obesity)
  • may increase the risk of mood swings
  • may increase the risk of depression

Many adults and even some children have experienced some form of sleep disorder. Unfortunately, sleep deprivation is becoming more and more common because many people sacrifice sleep to be more productive.

According to the CDC (Center for Disease Control), 30-70 million US adults have a sleep disorder. 35.2% of adults report sleeping less than 7 hours. Hawaii has the highest percentage of sleep disorders at 43%.

Symptoms of sleep deprivation

  • frequent yawning
  • tendency to doze off when inactive
  • feeling tired upon waking up in the morning
  • feeling drowsy all-day
  • poor concentration
  • mood changes (irritable)
  • reduces physical strength

  2. Intermittent- occurs periodically
  3. Chronic- occurs regularly.

Sleep Apneas

RLS is an overwhelming need to move the leg mostly associated with certain health (neurological) conditions such as ADHD and Parkinson´s disease.

Causes of sleep disorder

Many causes come from lifestyle, environmental, and health issues/medical conditions such as stress, hectic schedules, jet lag, hormones, and underlying health issues such as gastrointestinal issues like SIBO, IBS, depression, etc.

Please do not underestimate a good night´s rest. A lack of sleep can harm energy, mood, concentration, and overall health. In some cases, sleep disorders can be a symptom of other mental health conditions. It can affect the pituitary glands, can have metabolic effects, and can affect pro-inflammatory responses.

  1. I’m afraid that I am one such person who has trouble getting consistent uninterrupted full night’s sleep because there’s simply not enough time in a day to…

    1) hold down a day job

    2) side hustle blogging and all the tasks that come along with it (making videos, researching and blogging about topics, brainstorming, etc.)

    3) doing normal day-to-day chores

    4) doing family-related functions as a parent

    In fact, I’ve had nights where I get as little as 3 hours sleep from 1:30am bedtimes to 4:30am wake-ups to get ready to go to work.

    Even 5-hour nights would be a good night for me lately.

    Not sure what I can about it because I’m fully engaged in everything I do, but I recognize the long-term health impacts that you’ve pointed out in this post.

    So as far as I’m concerned, the clock is ticking on trying to be uncomfortable in the short term to make something extraordinary happen, but I also know that some has gotta give.

    • Thank you Jonny for sharing. It sounds like you have a lot on your plate. I can understand that you have obligations and goals to achieve. As you said yourself, you can´t keep this up for prolonged periods. Your body was not made to take on all this stress. Something is going to give. Keep your focus and make a priority list. Take care of the most important things first, and get to the other things next. Take care of yourself for your loved ones’ sakes, who would love to have you around for a long time to come full of energy and vitality.

      Hope you can find that healthy balance you need to perform at your utmost potential.

      All the best,
