Before we begin there are a couple of things you ought to know First the immune system isnt an organ like your heart or lungs Its a collection of things including your spleen your lymphatic system bone marrow white blood cells antibodies and more Thats why we call it a system and its a complex one Which is to say theres no single simple way to make your immune system better than everyone elses
But thats different than maintaining a balanced immune system which doctors say you should shoot for There are plenty of healthy habits to help you do that like through exercise and diet There is another important piece to the immunity puzzle that many of us overlook or take for granted SLEEP
Want to make sure your immune system is in tip top shape Consider the following
Get enough sleep
Science keeps telling us to get more sleep Its not that we dont want to its just life is busy However sleep deprivation might be sabotaging your ability to fight off infection and all types of viruses While you sleep your immune system releases cytokines If youre not sleeping enough you are actively reducing the production of these disease busting proteins
SleepYour Internal Body Armor
Given its well known impact on vigilance learning reaction time and mental acuity sleep loss has long been a topic of concern for military leaders and a focus of research by military scientists Less widely known however is the recent evidence showing that sleep is also critical for maintaining a healthy and effective immune system
It is now understood that sleep duration is a powerful predictor of infection In one study volunteers were exposed to the virus that causes the common cold Those averaging less than seven hours of sleep per night had a three fold greater risk of infection than those who slept eight hours or more for those who consistently slept less than five hours a night the risk was 4 ½ times greater
In addition limited but exciting evidence from animal studies suggesting that sleep not only helps protect against initial infection but also plays a direct role in aiding recovery from infectious illness
Lt Col Vincent Capaldi director of the Behavioral Biology Branch at the Walter Reed Army Institute of Research explains These studies show that sleep can enable and enhance your bodys ability to establish physical cognitive and now immunological dominance
Its All about Consistency
Whether you are trying to turn around chronic problems with sleep or deal with getting a good nights rest practicing good sleep hygiene is essential Here are some strategies for a 24 hour a day practice
Get up at the same time every day no matter what even when you go to bed later than usual This is especially important now when normal schedules are disrupted
Get exposure to sunlight Take a walk or at least sit outside Exposure to light in the morning even on a cloudy day resets your brain clock Without it your circadian rhythm and sleep wake schedule will be delayed
Limit caffeine after 2 pm
Exercise in the late afternoon or evening but at least four hours before bedtime Cooling down the body after exercising promotes good sleep
At night use the night mode on smart phones and tablets But avoid LED screens and monitors of any kind within one to two hours of bedtime especially nowadays when much of what we are watching is anxiety provoking
Go to bed when youre ready to sleep Try to set a bedtime that will get you seven or eight hours of sleep But if youre not sleepy dont get into bed until you are Dont worry if you wont get seven or eight hours of sleep on any given night That just makes it more difficult to fall asleep You can make up for sleep loss in naps the next day if need be
