Pain and Sleep
Exploring the relationship between pain and sleep.
Shingles, or Herpes Zoster, is a viral infection in the nerves of the skin that causes a painful, itchy blister-like rash. It is a reactivation of the chickenpox virus, and anyone who has ever had chickenpox is at risk of developing it.
Chickenpox causes itchy blisters throughout your body usually starting on your back, chest, or face. But the shingles rash is more painful than itchy. The rash also usually shows up on only one side of the body, often on your torso. But it can appear anywhere on your body. Shingles can range in seriousness from mild and attacking only a small part of the body to severe and widespread.
It can take a week to 10 days for the shingles rash to dry up and pain to subside. During that time enjoyment of life, general activities and, especially, sleep is diminished, according to a study published in the Canadian Medical Association Journal.
Shingles can affect people of any age, but it is most common in those over the age of 50. A person’s lifetime risk of getting shingles is about 30%, but that number increases as you age. There are also other factors that increase your risk of getting shingles.
Anyone who has ever had chicken pox is at risk for developing shingles. That’s because the chickenpox virus, known as Varicella-Zoster virus, never goes away. It lies dormant in the body. If and when it reactivates, it presents as shingles, also known as the Herpes Zoster virus.
Other factors that increase the risk for shingles include medical conditions or treatments that weaken your immune system. Some examples include HIV/AIDS or cancer; undergoing cancer treatment like radiation or chemotherapy; and some medications such as those used to prevent rejection of transplanted drugs or prolonged use of steroids.
Most people recover from shingles. But about half of people age 60 or older who get the disease may suffer from complications.
About 10% to 18% of people who get shingles will experience long-term nerve pain even after the rash goes away. This condition is known as postherpetic neuralgia, or PHN. The pain from PHN can last months or years and be so severe and debilitating it can interfere with daily life and nightly sleep.
In rare cases, shingles infection can spread to the lungs and cause pneumonia, to the liver and cause hepatitis, or to the brain and cause encephalitis. If the virus affects the facial nerve near one of your ears, it can cause facial paralysis and hearing loss. Shingles can also inflame the cornea of your eye. If the inflammation is severe, it can break down the cornea and cause vision loss. Shingles kills fewer than 100 people each year.
While stress isn’t itself considered a risk factor for shingles, research published in the journal Innovations in Clinical Neuroscience suggests that stress, stressful life events, and depression often precede outbreaks of shingles. One reason may be because stress lowers the body’s natural immune defenses and provides an opening for the dormant herpes virus to reactivate and surface.
Stress can adversely impact sleep and cause insomnia. But poor sleep can also add to your stress, leaving you suffering from excessive daytime sleepiness and making you prone to accidents, injury, and illness.
Ways to reduce stress include:
Shingles can make sleep difficult. Not only is the rash painful, it is often associated with fever, chills, fatigue, and headache, further exasperating your attempts to fall asleep or stay asleep.
The relationship between sleep and pain is also reciprocal. Pain can hinder sleep. But poor sleep can also lessen your tolerance to pain and worsen inflammation. These, in turn, can disrupt your sleep, causing a seemingly never-ending cycle.
Itchy skin can ruin your sleep, but for people who suffer from “chronic itch,” or chronic pruritic dermatosis, lack of sleep can be an ongoing problem. Researchers with Johns Hopkins, set out to see just how prevalent sleep problems were among people who suffer from “chronic itch conditions” and found 52.8% of people with chronic pruritic dermatosis reported trouble sleeping compared to those who did not have the condition. Chronic pruritic dermatosis sufferers said they had trouble falling asleep one to five times per month, woke during the night or too early in the morning, experienced leg jerks and cramping while sleeping, and felt overly sleepy the next day.
Other studies have shown that up to 87% of adults and 83 percent of children with eczema, another itchy skin condition that causes patches of itchy, inflamed, cracked skin, experienced sleep problems.
If you are suffering from shingles, chances are your painful rash is impacting your sleep as well, leaving you struggling with insomnia.
If you have shingles, you’re probably wondering what you can do to get better sleep. Let’s look at some treatments that can ease your itchy, painful rash so you can get a good night’s sleep.
Hot water can aggravate shingles pain, while cooler water can help temper the itchiness and pain associated with your shingles rash. Applying a wet, cool compress to your rash several times a day can help. Just soak a clean cloth in cool water, wring it out, and apply the cloth to your blisters.
Oatmeal is known for its moisturizing, soothing, and inflammation-relieving qualities. If your shingles rash feels unbearable, consider taking an oatmeal bath. Just add 1 to 2 cups of oatmeal to lukewarm bath water and soak for about 15 to 20 minutes.
Some dietary supplements, like papain, manuka and clover honey, L-lysinemay, may help ease the painful itch associated with the shingles rash.. If you are looking to improve your sleep, it may help to take a supplement of the sleep hormone melatonin.
If you’re desperate for an over-the-counter lotion or cream to treat your painful rash, you can try cool, soothing calamine lotion. But avoid antibiotic creams as they can slow the amount of time it takes for your rash to heal.
Anyone who has shingles will tell you it’s unpleasant and the cause of many sleepless nights. Even more disturbing is that you can get shingles more than once. The good news is that there is a vaccine available. The Centers for Disease Control and Prevention (CDC) recommends that healthy adults 50 years and older get two doses of the shingles vaccine called Shingrix, separated by 2 to 6 months, to prevent shingles and any complications with the virus.
Shingles is a reinfection of the chickenpox virus that can leave you in misery. Even worse, you can get it more than once. The outbreak can be mild or severe, and is sure to interfere with your sleep. If you are suffering, you are not alone. About 1 out of every 3 people in the United States will develop shingles — or an estimated 1 million each year. If you think you have the virus, seek medical attention right away and take heart in knowing your misery should be temporary.
