Does lack of sleep affect your immune system?

Yes

Sleep
Any physical or emotional stress, if significant, can affect your immune system. This includes lack of sleep, anxiety, emotional distress, etc. If you are having difficulty sleeping, try 20-30 minutes of exercise a couple of hours before bed. Melatonin is also a safe OTC supplement that helps some people adjust their day/night cycle.

Why does lack of sleep hurt your immune system?

Sleep and immunity

Sleep
Sleep does play a big role with many systems in our body. It does not actually get weaker it is simply that if the body is tired, the defense systems within the body will not be as alert.

Could you tell me how long it takes your immune system to recover from lack of sleep?

Immune/sleep

Immune_diseases
Some parts of the immune system (cellular mediated) are immediately changed (fast changes in chemical mediators such as cytokines), but humoral mediated immunity can sometimes take more time, such as weeks to months to recover, also dependent on degree of sleep deprivation and duration.

Dr. Robert Kwok answered:

I know that not sleeping enough hurts your immune system, but does sleeping more boost your immune system?

Maybe a little bit

Immune_diseases
A body that is very fatigued, due to lack of sleep, excess stress, being overworked, etc... may get sick more easily. If a person improves and returns to a normal type and duration of sleep, he will no longer have a "lack of sleep". His body and immune system will become more "normal", so his chances of getting sick will be similar to that of a healthy person. Sleeping even more hours won't help.

Is sleep for a strong immune system imporant?

Delta phase sleep

Open-uri20130525-792-1oj82cs
There are several phases of sleep and one of the most important levels for maximum rest and renovation is delta phase. This is the deepest level of sleep in which HGH (human growth hormone) is released and in adults provides one of the most potented hormones that naturally helps prevent tissue and organ breakdown. It may be that you have a sleep disorder preventing this level of sleep.

How long do I have to be sleep deprived before it shows effects on my immune system?

Chronic just as bad

Sleep_deprivation
Sleep deprivation definitely affects the immune system. Chronic sleep deprivation (insomnia, sleep apnea, etc.) definitely affects the immune system.

Ways I can boost my immune system? I work 2 jobs with 65 hours a week in total, I don't sleep much and I eat once a day. Is this a contributor?

Immune system

Sleep
Life style and diet certainly effects your immune system. You are working very hard, but I would find a way to take a few snacks during the day e.g. a handful of nuts or a health bar. Try to find a way to get more sleep or try to take a nap. Take a multivitamin daily.
