Newman Memorial now offers Sleep Studies:  Healthy sleep habits add up to better overall health


Many Americans skimp on sleep thinking there’s no harm in missing a few hours here or there to maximize hours spent working or having fun. But, Sean Tucker, M.D., Chesapeake Health Center, says routinely missing sleep can have serious side effects.


“Sleep is not a luxury, it’s a necessity,” says Dr. Tucker. “It’s the only time your body has to repair and restore itself.”


What happens when you sleep?


 “Your brain doesn’t just turn off when you go to sleep,” says Dr. Tucker. “Some parts of your brain are very active during your sleep cycles.”


A brain’s glymphatic system is highly active during sleep. Because the glymphatic system acts as your brain’s “drainage system,” getting enough sleep helps your brain remove and recycle toxins, proteins and other items it needs to work properly. Another important process that occurs during sleep is cellular repair. During deep sleep, your brain secretes chemicals that repair your cells after the wear and tear they experience during the day.


Your brain also organizes the chaos created by everything you see, hear, taste, touch and otherwise experience during the day. With so many stimuli vying for our attention the brain can’t properly process all information that comes in, so it needs time during sleep to create memories.


“We all have a circadian rhythm, an internal clock that regulates our sleep-wake homeostasis,” says Dr. Tucker. “This is particularly sensitive to internal stimuli and external stimuli from the environment. For example, changes in light exposure, various medications and foods can affect this internal clock rendering us susceptible to sleep variations.”


What’s the harm in skimping on sleep?


Lack of sleep can cause brain fog. Dr. Tucker says that foggy feeling is caused by changes in how your tired brain functions:


• Sleepiness slows down your thought processes: Sleep deprivation causes lower alertness and concentration. This makes it harder to focus and pay attention, leading to confusion.  It is also harder to complete tasks that require logical reasoning or complex thought.

• Sleepiness impairs memory: Research suggests that sleep helps strengthen the nerve connections that make our memories. Without enough sleep, your brain has a harder time making short-term memories. This often leads to forgetfulness.

• Poor sleep makes learning harder: A sleep-deprived brain has trouble focusing, which makes it harder to pick up new information. It also affects your memory, which is essential to learning and retaining new information.

• Sleep deficits slow down reaction times: This is one of the most dangerous side effects of a sleep deficit. Your brain and nervous system has a hard time reacting to the world around you when you haven’t had enough sleep. The National Highway Traffic Safety Administration conservatively estimates that at least 100,000 crashes reported to police are due to drowsy driving.


What about medical conditions that interrupt sleep?


“For some people, sleep is simply harder to get because they suffer from a medical sleep condition,” says Dr. Tucker. “While sleep can be harder for these people, it’s not impossible.”

Currently there are 84 recognized sleep disorders, but three affect more people than others: insomnia, sleep apnea and restless legs syndrome.


Insomnia is perhaps the most discussed sleep disorder. True insomnia is defined as an inability to initiate or maintain sleep. Insomnia can lead to excessive daytime sleepiness and how you function throughout the day. Some people suffer from what is called “learned insomnia.” These people are plagued by a fear of being unable to sleep. If you suffer from an inability to fall asleep or stay asleep, talk to your doctor. Different forms of insomnia can be treated with antidepressants or sedatives along with behavioral changes.


Sleep apnea is a common sleep disorder in America. Approximately 200,000 cases of sleep apnea are treated in the United States every year. People with sleep apnea experience an interruption in their breathing while they are sleeping. Sleeping partners report hearing periodic gasping noises, and often the disruption in breathing results in a disruption in sleep. Because this disrupts sleep, it can cause excessive daytime sleepiness.


In addition, the disruption in breathing poses other serious health complications. Symptoms should be taken seriously, and if you think you may suffer from sleep apnea, you should ask your doctor about it. Different oral devices can help ease symptoms. Another common treatment is the use of a positive air pressure machine, commonly called a CPAP, which supplies pressurized air flow to your throat.


Another common condition that disrupts sleep is restless legs syndrome, which Dr. Tucker says is a neurological disorder.


“The hallmark symptom of restless legs syndrome is an unpleasant sensation in the legs,” he says. “These sensations come with an uncontrollable urge to move your legs.”


Restless legs syndrome is caused by an abnormality in the neurotransmitter dopamine. Typically doctors combine medication that helps normalize dopamine levels with medication that promotes continuous sleep.


 What can you do to develop healthy sleep habits?


“Consistent routines help our bodies and minds prepare for sleep,” says Dr. Tucker. “Creating a routine that helps you wind down at about the same time every night can go a long way to preparing your body for sleep. In general, you’ll want to start your bedtime routine about an hour before you want to fall asleep,” he added.


Some other tips to build a sleep friendly routine and environment include:


• Avoid caffeine and vigorous exercise within six hours of sleep

• Keep electronics – TV, computer, mobile devices, etc. – out of the bedroom

• Silence or turn off your cell phone when going to bed

• Make sure your room temperature isn’t too warm or cold

• If you can’t fall asleep within 20 minutes of going to bed, get up and read – return to bed only when sleepy


How much sleep do you need?


Dr. Tucker says sleep needs can depend on the person and their activity level, but in general these are the recommended amounts of sleep a person needs based on age:


• 0-3 months: 14-17 hours each day

• 4-11 months: 12-15 hours each day

• 1-2 years: 12-15 hours each day

• 3-5 years: 10-13 hours each day

• 6-13 years: 9-11 hours each day

• 14-17 years: 8-10 hours each day

• 18-64 years: 7-9 hours each day

• 65+ years: 7-8 hours each day


What can you do if proper sleep is an ongoing problem?


Getting the appropriate amount of sleep is so essential for good overall health that if you are struggling in this area, it isn’t something to ignore.  The first step is to talk to your doctor.  Your primary care physician can look at things like medication and lifestyle to assess your particular circumstance.  Your doctor may also decide that you could benefit from a sleep study for a deeper analysis of the issue.  Either way, you can’t be your best self without good sleep.  Don’t put it off, talk to your physician today!
