Amidst growing concern about COVID 19 infection
health officials have provided several recommendations to help individuals protect themselves and their families from infection including washing hands regularly and maintaining a distance of at least six feet from anyone who is coughing or sneezing
Fortunately a growing body of evidence suggests that an additional lifestyle modification could also dramatically improve your odds of avoiding infection getting more sleep
It has long been known that sleep is important for military performance The Walter Reed
Army Institute of Research WRAIR has conducted sleep studies since the 1950s showing that sleep loss negatively affects emotional regulation judgment cognitive performance learning and memory psychological resilience and reaction time each of which could be critical for success in multi domain operational environmentsand almost all other environments as well from the athletic field to the classroom to the boardroom This is why elite athletes make sure they obtain 8 10 hours of sleep per night to acquire that extra edge that can make the difference between success and failureIn addition and of particular relevance given current concerns about the spread of COVID 19 recent evidence suggests that sleep is also important for healthy immune function and the ability to fight off infection
The relationship between sleep and infectious disease is now being explored by researchers across the world and several interesting and important findings have been reported
For example in one study volunteers without previous exposure to the common cold were exposed to a live sample of the virus Researchers found that no variable predicted whether a participant would fall sick better than sleep duration not even age or stress level In other words those who habitually slept less were more likely to fall ill with the cold virus
In another study conducted by the same group a sleep threshold was discovered individuals who averaged less than seven hours of sleep per night were found to have a three fold greater risk of infection relative to those who averaged eight or more that rate climbed to a 4 ½ fold greater risk for those with less than five hours of sleep
Perhaps most surprisingly it has also been found that six months after receiving a hepatitis B vaccination individuals who slept fewer than six hours on the night prior to vaccination were at significant risk of being unprotected compared to those who had obtained more than seven hours of sleep
In addition there is now limited but exciting evidence from animal studies suggesting that sleep not only helps protect against initial infection it also plays a direct role in aiding recovery from infectious illness
Although there have not yet been any studies in which the relationship between sleep duration and COVID 19 infection have been studied directly lessons learned from studying the relationship between sleep duration and other infectious diseases can readily be generalized to COVID 19
Sleep is critical for maintaining physical cognitive and immunological dominance on and off the battlefield Leaders must prioritize sleep as a valuable asset in maintaining readiness and resilience especially in the context of multi domain operations and increased health risks worldwideincluding those risks associated with exposure to infectious diseases says Army Lt Col Vincent Capaldi director of the Behavioral Biology branch at Walter Reed Army Institute of Research responsible for studying the relationship between sleep performance and military effectiveness
Unfortunately approximately one in three American adults do not obtain the American Academy of Sleep Medicine recommended 7+ hours of sleep per night a situation that is estimated to cost the US economy approximately $411 billion a year due to increased errors and accidents lower productivity and increased absenteeism And the problem is particularly pronounced in the military where approximately two in three Soldiers average six or fewer hours of sleep a night
Sleep and infectious disease researchers are also jointly exploring the relationship between sleep and immune function a natural collaboration since the WRAIR infectious disease research programs are among the best in the world having contributed to the development of many FDA approved vaccines and every existing FDA approved malaria prevention drug
Furthermore WRAIRs world renowned sleep and performance research program has generated several technological and knowledge products including wrist actigraphy a precursor to current smartwatch technology to reliably measure and quantify sleep in the field human functional brain imaging studies that have furthered scientific understanding of sleep and sleep loss and the discovery of sleep banking the finding that extra sleep prior to a mission with sleep loss blunts the performance decrement and reduces the amount of sleep needed to fully recover afterwardAs medical countermeasure development efforts progress obtaining at least seven hours of sleep per night in a comfortable cool quiet dark and safe area in addition to regular handwashing with soap and water and maintaining a healthy social distance 6 feet will continue to constitute the first line of defense against infection
Do You Have Sleep Apnea
A first step to determine if you suffer from sleep apnea is talking to your physician It is important to identify the source of snoring or uninterrupted sleep Without treatment additional exhaustion and fatigue will negatively affect your underactive thyroid
Keep a Sleep Journal
The next step would be a sleep diary In the diary record important bits of information such as what time you went to bed how long it took to fall asleep how long you slept how difficult it was to wake in the morning how tired you felt the next day and list amount of caffeinated or alcoholic beverages consumed during the day as well as medications you may have taken
A sleep study may be the best route to link sleepiness Though the type of sleep study varies by a patients symptoms healthcare providers will monitor your sleep either in a lab or at your home using portable home sleep apnea testing equipment Completing a sleep study can also enhance your quality of life from hypothyroidism which already is most likely taking away a full nights rest
If you live in Alaska and are ready to take back your sleep contact The Alaska Sleep Clinic and receive a free 10 minute phone consultation with a sleep educator who can help you determine if a sleep study is right for you
