  • Short-term consequences of sleep deprivation include deceased attention and memory retention, sleepiness, increased risk of accidents, increased hunger and decreased mood.
  • Long-term consequences of sleep deprivation includes increased risk of disease and death, increased obesity, and increased risk of chronic diseases such as type 2 diabetes, heart disease, and depression.
  • Weight, sleep apnea, and hypogonadism can be physical barriers to healthy sleep.
  • Tips on how to fall asleep include decreasing light exposure, lowering temperature of the room, exercise earlier in the day, and avoid caffeine and exercise closer to bed time.

Sleep has been hailed as a critical factor contributing to our overall wellness for many decades, but diet and exercise are often perceived as the ultimate priorities for effective health management. Yet, nutrition and fitness cannot compensate for the effects of poor sleep quality. In fact, both the length of time we spend sleeping each night as well as the quality of the sleep we achieve play a major role in our vitality, largely dictating our risk of developing serious diseases such as type 2 diabetes and cardiovascular disease.

It can be safely assumed that everyone has experienced a poor night of sleep at least once in their lifetime, and although sleep deprivation is rampant across the country, it is impossible to gauge just how many individuals are affected by lost sleep. What we do know is that roughly 50-70 million U.S. adults have a sleep disorder.[1] With that said, even undiagnosed sleep issues raise serious concerns: both repeated instances of severe sleep deprivation as well as chronic sleep deprivation can have negative impacts on key health outcomes.

Within this guide, we will take a closer look at the complex ways in which sleep affects our health. We will also explore the most common causes of disordered sleep and present tactics for overcoming these and other impediments to achieving ample, quality sleep.

Short and Long-Term Consequences of Sleep Deprivation


Consequences of sleep deprivation can have short term and long term effects, short term consequences of sleep deprivation may include problems with memory to increased moodiness and hunger, long term consequences of sleep deprivation include increased risk of developing chronic diseases such as cardiovascular disease and type 2 diabetes

The Textbook of Age
Management Medicine: Volume 1
highlights both short- and long-term
consequences of sleep deprivation. On a short-term basis, individuals who have
recently experienced lack of sleep may experience:

On a long-term
basis, consequences of sleep deprivation include:

Yet, the question remains: Why does lack of sleep increase our risk of these serious health issues? While there is still much to be learned about the impact of sleep on the body, we do know inflammation certainly plays a role in the relationship.

Sleep and Inflammation

Inflammation is one of the long term consequences of sleep deprivation, inflammation due to sleep deprivation is a large contributor in the development of cardiovascular disease

Inflammation is a well-established agent in the development of cardiovascular disease. A sustained increase in low-density lipoprotein (LPL, also known as the “bad” cholesterol), results in an accumulation of LDL in previously damaged arterial walls. This results in an inflammatory response that propagates plaque formation, thereby contributing to cardiovascular disease.

In the Textbook of Age Management Medicine: Volume 1, the relationship between sleep and inflammation is explored in great detail. In summation, sleep deprivation is inversely associated with plaque formation and coronary artery calcification in middle-aged adults. Sleep deprivation is also inversely associated with the thickness of the carotid intima media, or the innermost layer of artery walls. Several pro-inflammatory markers are inversely associated with sleep duration. In other words, the fewer hours a person sleeps, the more likely they are to experience elevated levels of inflammatory markers. In fact, these markers can be elevated in as little as one night of complete missed sleep. Because pro-inflammatory reactions are linked to a host of serious health conditions, such as stroke, cardiovascular disease, and type 2 diabetes, achieving the recommended number of hours of sleep each night is essential to long-term wellness.

Yet, while it is abundantly clear that sleep quality and duration are critical to health, many individuals still struggle to achieve a restful night of sleep. What are the most predominant barriers preventing us from achieving quality sleep?

Why Can’t I Sleep – Physical Barriers


There are many physical barriers that may explain “why can’t I sleep”, sleep apnea and weight regulation are large contributors as barriers to healthy sleep

There are many possible causes behind sleep deprivation, which is why the issue cannot be met with a “one-size-fits-all” approach to treatment. The inability to get to sleep – and remain sleeping for a full seven to nine hours – can be a result of either physical or psychological difficulties. For individuals struggling with psychological barriers, behavioral and cognitive treatments can be explored to enhance sleep without medical intervention.

With that said, many sleep issues are related to physical issues. Below, we’ll explore some of the most prevalent physical barriers to sleep.

Sleep Apnea

Obstructive sleep apnea (OSA) occurs when the airflow is insufficient for metabolic demands. The collapse of the pharynx results in this obstruction: when muscle dilator activity becomes insufficient to maintain the pharynx, obstruction occurs.

Weight Regulation

Weight regulation is a key player in the prevention and treatment of OSA. Results of a randomized control study of patients with type 2 diabetes and an average BMI of 36 and an average AHI of 23.2 show individuals who lost 22 pounds or more in a one-year period witnessed an improvement of 9.7 in their AHI scores. They were also three times as likely to have a complete remission of OSA. The reduction of AHI scores was directly related to the degree of reduction in weight. It can therefore be concluded that OSA could simply be considered a complication of obesity in many cases.[3]

Weight loss, like sleep complications, cannot be approached the same way for every patient. A combination of reduction in calories, adherence to a healthy eating plan with restricted or no intake of processed foods, and a tailored exercise program can be personalized to meet the weight loss needs and goals, as well as the personal preferences and lifestyle considerations, of each patient. Compliance is the most critical factor of all weight loss endeavors, which is why starting with a patient-oriented approach is essential.

Hypogonadism and Sleep

There is a suspected relationship between sleep disorders and hormones. Specifically, testosterone impacts the organization of circadian rhythms and timing of sleep. This relationship takes on a cyclical pattern: total sleep deprivation can also lower testosterone.

Additionally, the Textbook of Age Management Medicine: Volume 1 indicates there is a relationship among hypogonadism, or the failure of the reproductive organs to produce appropriate hormone levels, and OSA. The text examines study findings which point to a significant negative correlation of testosterone levels with AHI, indicating that low testosterone is associated with higher OSA symptoms.

Testosterone has been observed to have a destabilizing effect on ventilation. Leuprolide used to treat androgen deprivation has been shown to increase apneic episodes, but it should be noted that these findings were discovered in studies performed on obese men. With that said, similar findings have been observed in hypogonadal men treated with testosterone replacement.

Hypogonadism in males can either be primary, meaning it originates from a problem in the testicles, or secondary. In the latter case, low hormone levels could result from an issue in the pituitary gland, or the part of the brain signaling the production of testosterone. This can be either an inherited trait or acquired as a result of injury, infection, normal aging, or obesity.[4]

The most effective treatment of hypogonadism is therefore dependent on its underlying cause. In obese patients, for example, dietary and lifestyle changes can be prescribed to manage hypogonadism. Testosterone replacement therapy is also a viable form of treatment for many men and can result in increased energy, libido, erectile function, and an overall improved sense of wellbeing, in addition to improved sleep cycles. If the condition is a result of a pituitary issue, pituitary hormones may be administered to restore fertility and stimulate the production of sperm.

Other Sleep Impediments


Blue light from devices such as computers and smart phones can answer the question “why can’t I sleep” for many patients, exposure to certain types of light can be a barrier to healthy sleep, tips on how to fall asleep include turning off devices to create a dark room and lowering the temperature to create a better sleeping environment

In addition to the factors described above, there are a number of other lifestyle considerations that could inhibit proper sleep. Sleep hygiene, a term that was coined in the late 1970s, aims to control environmental and behavioral factors that can promote better quality sleep through certain habits and practices. Worry and stress, the intake of stimulants such as alcohol, caffeine, and nicotine, failure to establish a regular sleep schedule, and exposure to light (including blue light from devices such as smart phones and tablets) can all impair sleep hygiene.[5]

Tips on How to Fall Asleep


Beyond treating known issues contributing to sleep problems such as obesity, OSA, and hormone imbalances, quality sleep may be achieved by making some simple adjustments to your daily routine. Here are some tips worth considering, which D’Alessandro recommends both for his clients and anyone seeking improved sleep behaviors:

  1. Spend at least 20 minutes in a dark, cool room prior to going to sleep. This includes staying away from both handheld devices such as tablets and smart phones as well as larger technology, including televisions. The light from these devices can alter the body’s natural rhythm, making it more difficult to ease into deep sleep.
  2. Lower the temperature. A decrease in core temperature is necessary for entering REM sleep. Elevated temperatures, on the other hand, can cause restlessness and poor sleep.
  3. Avoid caffeine and exercise sessions too close to bed time. These factors can lead to increases in heart rate and blood pressure. Exercising and taking in caffeine too close to your normal bedtime may therefore make it difficult to bring your vitals down to baseline measures when it is time to sleep.
  4. Consider taking naps. When taken early in the afternoon or earlier in the day, naps of no more than 30 minutes have shown to improve cognition and focus. The catch is that limiting naps to 30 minutes or less is the required “sweet spot” needed to reap the benefits: any longer and you may experience an adverse effect, feeling groggy upon waking up. Additionally, naps should also be taken in a cool, dark place.[6]
  5. Exercise and weight train early, if possible. The increased muscle protein and fuel breakdown resulting from exercise requires our body to crave more recovery. Therefore, your body will make a more concerted effort to enter deep sleep if you work out regularly. You may also be more likely to stay asleep. Again, however, be mindful of avoiding exercise in the hours leading up to your normal bedtime.

The Solution for Sleep in Middle Age & Beyond


Cenegenics physicians provide more than quick fixes on how to fall asleep, Cenegenics physicians examine the reasons why you can’t sleep and attempt to alleviate the consequences of sleep deprivation through expert treatment that will better your sleep quality

Sleep is critical to mental and physical functionality at every stage of life, but it may have the greatest potential to be impacted as we age. When individuals experience natural age-related changes such as a decline in metabolism and hormonal variations, they may become more susceptible to conditions such as OSA, obesity, and other factors that influence sleep duration and quality. Thus, treating the underlying conditions contributing to sleep deprivation – rather than providing “quick fixes” for sleep issues – is essential to achieving lasting results.

Clinicians specializing in age management are therefore best equipped for helping middle-aged and older populations achieve better sleep. These experts take an all-encompassing approach to treatment, factoring in all of the different biomarkers which could impact sleep quality and duration. Through exercise, nutrition, and other lifestyle recommendations along with medical treatment if needed, they can help patients achieve better sleep patterns to make lasting improvements in sleep quality and duration, as well as overall wellness.
