Sleep and the Immune System

Sleep and the Immune System

If you’re not making sleep a priority, it will catch up with you—in fact, maybe it already has. Are you prone to catching colds? Is it harder to recover from infections, wounds, or other ailments? Sleep and the Immune System work together, and rely on each other, to keep your body strong and disease free.

Getting adequate sleep bolsters your immunity which helps you to get sick less often—and heal more quickly. A weak immune system makes you more susceptible to illnesses. This can hinder or prevent, sleep. Viewed this way, it’s easy to see that sleep and the immune system should be kept top-of-mind.

Prioritizing your Sleep

It's essential to maintain a fully functioning immune system; anything less deprives us of robust health. Bottom line, sleep loss—even in the short-term—can compromise immunity in the long-term.

Getting quality sleep should never be an afterthought...

Practice being mindful; keeping an intentional focus on sleep and the immune system is key. Neglecting sleep to deal with life's other urgencies is just a bad idea.

Making sure you get the right amount of uninterrupted sleep each night helps ready your immune system to respond and perform at its best. This should go hand-in-hand with managing your daytime habits—such as:

  • Eating whole foods
  • Regular Exercising
  • Managing stress

And, as always, consider seeking expert and/or medical advice. Good or bad, everything we do has the potential to affect how well we sleep.

Ignoring your sleep won't result in good news...

Consequences—they're inevitable and one of the primary rules of life. The consequences of poor health choices are guaranteed to be unpleasant. In extreme cases they may even be life-threatening.

Inaction—as well as action—can bring these consequences. If you aren't actively protecting your immune system — If you think it’s “good enough” to simply not put “bad things” into your body—or that it’s ok to skimp on your sleep to fit in other activities… think again…

What’s the worst that can happen?

An impaired immune system cannot mount a fully effective response to the lurking array of germs and diseases we're exposed to each day. When your system is weak, you are constantly open to attack from bacteria, viruses, parasites and other malicious invaders.

Compromised immunity may result in any number of annoying afflictions (frequent sniffles, allergies, earaches, stomach upset.) We often brush these seemingly minor bouts off as manageable—but they just keep coming back. As they repeatedly hammer away at our immune reserves, it takes longer to recover—the immune system continues to weaken— increasing our susceptibility to infectious disease and chronic illnesses.

How much sleep do you need?

Studies continue to support the link between Sleep and the Immune System. These findings tell us why sleep is critical for optimum immune function:

  1. We need 6-7 hours of sleep per night to help ward off infection.
  2. There is a greater risk of developing life-threatening conditions (including depression, diabetes, heart disease, inflammation and obesity) in subjects experiencing regular sleep loss.

The recommended number of sleep hours for adults is 7-9 hours depending on your age. That said, follow what your body tells you. How many hours do you need to feel rested and healthy?

Yawning, daytime fatigue, being unable to concentrate... these are all common signs you may suffer from sleepdeprivation.

Signs you may be sleep deprived…

  • Daytime fatigue / Inability to concentrate
  • Increased appetite / Weight gain
  • Emotional outbursts / Impulsive behavior
  • Clumsiness / Impaired decision-making
  • Undereye circles / Skin blemishes
  • Vision problems / Prone to illness

Your immunity may need a boost if you …

  • Always feel tired
  • Are highly anxious
  • Catch cold easily
  • Have constant digestive issues
  • Get frequent infections
  • Have slow-healing wounds

These lists are not dis-similar, which underscores that critical link between Sleep and the Immune System. Boost your sleep—boost your immune system. Boost your immune system—boost your sleep…
