Do hives get worse at night
Can COVID-19 Cause Hives at Night?
Hives are a common symptom of COVID-19 that can occur during the day or night. Hives only at night might be from something youre coming into contact with in the evenings.
COVID-19 can cause hives during the day and night. They often show up early in the infection and may even be the first symptom you notice.
COVID-19 can cause several skin symptoms, including rashes and hives. These symptoms are typically brief, but in some cases, they last for months after the initial infection.
Hives develop when your immune system releases histamine in response to a perceived threat, like an allergen or infection. While hives can occur with infections like COVID-19, theyre more often associated with allergic reactions. You can have an allergy to something you eat, a medication youre taking, or an irritant that touches your skin.
Keep reading to learn more about hives and their connection to COVID-19, and whether its normal for them to appear only at night. Also, learn about treatments for hives and other skin conditions triggered by COVID-19.
Research has identified a link between hives and COVID-19. According to a
Researchers examined 63 articles and discovered that hives usually appear with other COVID-19 symptoms, like cough and fever. They last an average of 6.8 days.
Medications used to treat COVID-19 can also trigger hives.
Doctors need to conduct more research into how the coronavirus triggers hives.
Researchers in a 2020 literature review analyzed 46 articles that pooled the details of 998 people who got COVID-19 early in the pandemic. Among this group, 89 people, or 8.9%, developed hives.
Researchers noted that skin conditions are underreported with COVID-19 because they may develop early in the infection before other more identifiable symptoms appear.
Its normal for hives to come and go. But hives that appear only at night arent a symptom typically associated with COVID-19.
If youre getting hives only at night, it may be because youre coming into contact with an allergen in the evenings.
Detergents in clothes or bedsheets, lotions, or medications you take before bed could all cause hives at night. Alpha-gal syndrome can also trigger hives at night.
Alpha-gal syndrome is caused by a tick bite. The condition can cause hives or an itchy rash after eating meat or other animal products.

Possible causes of hives at night
If you get hives only at night, it may be related to something youre coming into contact with late in the day. Some possibilities include:
- detergents used on clothing or sheets
- lotions or creams applied at night
- medication taken at night
- stress
- pressure from tight clothing, like a belt, or any part of the body under continual pressure
- changes in temperature, like very cold air or water, sweating, or a hot shower
- environmental allergens, like dust, mold, pollen, or animal dander
There are several ways that COVID-19 can affect your skin.
The
Other rashes that might appear when you have COVID-19 include:
Maculopapular
A maculopather rash is an itchy rash with both flat and raised parts. It often appears on the torso but can develop anywhere on the body. It can appear before or after other COVID-19 symptoms and typically lasts about 812 days.
Chilblain-like
Commonly known as COVID toes, this chilblain-like condition causes swelling and redness in your toes and, less commonly, your fingers. Its more common in children and young adults. It usually appears later in the infection.
Vesicular
A vesicular type of rash causes a blister-like appearance. Its more common in middle-aged adults. It may appear 430 days after other symptoms, with an average onset of 14 days. Typically, the rash clears up within 810 days.
Petechiae
Petechise is a rash that produces small, pinpoint red, purple, or brown spots beneath the skin on the torso, arms, and legs. Its not as common with COVID-19 as other rashes, but it can appear after other symptoms.
Livedoid eruptions
This rare symptom produces a blotchy rash that looks like a net. It appears at the same time as other symptoms. On average, it lasts about 9 days.
Hives can be distressing and itchy, but home remedies may help relieve discomfort. Most hives will go away on their own within a few hours, but while theyre visible you can:
- use an over-the-counter anti-itch cream, like calamine lotion
- apply a cold compress, like ice cubes wrapped in a towel, on areas that itch
- take an antihistamine or allergy medication
- use a fragrance-free moisturizer throughout the day
- practice self-care and stress-relieving strategies, as stress can trigger hives or make them worse
- keep a record of flare-ups to try and track the cause
- wear loose, breathable clothing
Many people experience an occasional outbreak of hives that respond to treatment at home.
If your hives last longer than 6 weeks or repeatedly flare up over this time, you may want to talk with a doctor. The American Academy of Dermatology recommends visiting a board certified dermatologist, allergist, or primary care doctor.
A doctor can help determine whats causing your hives and make sure nothing serious is going on. If they cant narrow in on the cause of your hives, your doctor might recommend allergy testing.
COVID-19 can cause several skin reactions, including hives. They usually appear at the beginning of the infection, sometimes before other symptoms develop. Hives from COVID-19 may come and go at any time of the day or night.
Hives that happen only at night are more likely caused by foods or other allergens, like detergents, lotions, or soaps. Things in your environment, like dust, pollen, and pet dander, can also trigger hives.
Most hives respond to over-the-counter treatment, like anti-itch creams, antihistamines, or allergy medications.
Hives (Urticaria)
What are hives?
Hives, or urticaria, are flat red welts that can appear anywhere on the skin and usually itch. Hives often occur as an allergic reaction to something eaten or something that has contacted the skin. Foods, medicines, and plants are common causes, but sun exposure, stress, infections, and autoimmune diseases have also been known to cause hives.
Symptoms include an itchy, stinging pink rash of slightly swollen skin. The rash may wax and wane in severity. Acute hives typically resolve within six weeks, but chronic hives (urticaria) can persist for months or years.
Hives often resolve on their own, especially in children. Otherwise, treatment for acute hives involves oral antihistamine medications to help relieve the itching and stinging. Chronic hives that do not improve with antihistamines may be treated additionally with corticosteroids, antibiotics, and other stronger medicines. A study found that 35% of people with chronic hives, are symptom free within one year, with another 29% having some reduction of symptoms.
You can safely treat this condition on your own as long as you does not develop trouble breathing. Any antihistamine (like Zyrtec, Clarinex, etc) works.
Hives at night: Alpha-gal syndrome?
For the past five nights, including tonight, I have been experiencing a reaction of some sort. I assume that they are hives. The weird thing is that it only happens, well 95% of the time, the breakout starts in the evening. I know it's not from a bite or something because they are in different spots each night... I have had an allergy test ..that was done a few years back and it came back negative. Not allergic to anything. I know that can change, but I just find it odd that this only happens at night. During the day, I am fine... just anxious know what's to come after sundown. Another thing I noticed is that they are usually in straight lines.. not always, sometimes they are blotchy but a lot of the time they are in lines. I have taken benadryl every night for the past few nights... didn't work. Tonight I got a little bit of relief but I can already feel my body getting itchy. Hydrocortisone creams do nothing. I think I just apply them for piece of mind. I called my primary's after hours answering service and spoke with my doc. I have an appt with her in the morning and she is going to do bloodwork and give me steroid shots, but I just wanted to see if anyone else has experienced anything like this before or know someone who has.
They usually last for the night. When I can finally get myself to sleep at night.. in the morning i am fine. They dont leave any markings or anything. They are just red and raised and extremely itchy.
Any input will help. Thanks in advance.

Itchy Skin at Night? Why It Happens and What You Can Do About It
Having itchy skin at night can occur naturally due to changes in body temperature and water loss. Sometimes, it may be a symptom of an underlying condition.
Itchy skin at night, called nocturnal pruritus, can be severe enough to disrupt sleep regularly. Why this happens can range from natural causes to more serious health concerns.
You may experience itchy sensations when trying to go to sleep, or it may be severe enough to wake you up during the night. Some people may scratch these itches unconsciously while asleep.
Causes of itchy skin at night can range from changes in skin function as part of the natural circadian rhythm, bug infestations, or underlying health conditions.
This article discusses the potential causes and available treatments for itchy skin at night.
For most people, natural mechanisms could be behind nighttime itch. Your bodys natural circadian rhythms, or daily cycles, influence skin functions like temperature regulation, fluid balance, and barrier protection.
Circadian rhythm
These skin functions change at night. For example, your body temperature and the blood flow to your skin both increase in the evening, warming your skin. A rise in skin temperature can make you feel itchy.
Your bodys release of certain substances also varies by time of day. At night, you release more cytokines, which increase inflammation. Meanwhile, the production of corticosteroids hormones that reduce inflammation slows.
Hydration
On top of these factors, your skin loses more water at night. As you might have noticed, during the dry winter months, parched skin itches.
When itchiness hits during the day, work and other activities distract you from the annoying sensation. At night there are fewer distractions, which can make the itch feel even more intense.
Insects
bugs like scabies, lice, bedbugs, and pinworms are often
Along with your bodys natural circadian rhythms, a number of different health conditions can cause itchy skin to become worse at night. These include:
- skin diseases, such as atopic dermatitis (eczema), psoriasis, and hives
- kidney or liver disease
- iron-deficiency anemia
- thyroid problems
- mental health conditions, such as stress, depression, and schizophrenia
- restless legs syndrome (RLS)
- cancers, such as leukemia and lymphoma
- nerve disorders, such as multiple sclerosis, shingles, and diabetes
- allergic reactions to substances like chemicals, drugs, foods, or cosmetics
- pregnancy
Here are a few medicines and home remedies to relieve itchy skin at night.
Prescription and over-the-counter medications
If a condition like a nerve disorder or RLS is causing the itch, talk with your doctor to get it treated. To treat nighttime itch yourself, you can try an over-the-counter or prescription medicine. Some of these medicines relieve just the itch. Others help you sleep. A few do both.
- Older antihistamines, such as chlorpheniramine (Chlor-Trimeton), diphenhydramine (Benadryl), hydroxyzine (Vistaril), and promethazine (Phenergan), relieve the itch and make you sleepy.
- Newer antihistamines, such as fexofenadine (Allegra) or cetirizine (Zyrtec), are also helpful and may be taken at night or during the day.
- Steroid creams stop the itch at the source.
- Antidepressants like mirtazapine (Remeron) and doxepin (Silenor) have an anti-itch and sedative effect.
Be sure to check with your doctor before trying any new medications or treatments, and exercise caution if youre pregnant or breastfeeding.
Alternative treatments
To help you sleep, you could try melatonin. This natural hormone helps regulate sleep. When you take it nightly, it has a sedative effect that can help you sleep through the itch.
Home remedies and lifestyle changes
If stress aggravates your skin, try techniques like meditation, yoga, or progressive muscle relaxation to calm your mind.
You can also meet with a therapist for cognitive behavioral therapy (CBT). This program helps reverse some of the negative or inaccurate thoughts and actions that aggravate your stress.
You can also try these home remedies:
- Apply a lubricating, alcohol-free moisturizer to your skin during the day and before bed.
- Apply cool, wet compresses to soothe the itch.
- Take a bath in lukewarm water and colloidal oatmeal or baking soda.
- Turn on a humidifier. It will add moisture to the air in your bedroom while you sleep.
If your skin itches at night, here are a few triggers to avoid:
- Try not to go to bed in anything itchy. You can wear pajamas made from soft, natural fibers like cotton or silk.
- Keep the temperature in your room cool around 60 to 65F. Overheating can make you itch.
- Avoid caffeine and alcohol before bed. They widen blood vessels and send more blood to warm your skin.
- Try not to use any cosmetics, perfumed creams, scented soaps, or other products that might irritate your skin.
- Try not to scratch. You can irritate your skin even more. Try to keep your fingernails short if you feel the urge to scratch at night.
Talk with your primary care doctor or a dermatologist if:
- The itching doesnt improve within 2 weeks.
- You cant sleep because the itch is so intense.
- You have other symptoms, such as weight loss, fever, weakness, or a rash.
If you dont already have a primary care doctor or a dermatologist, the Healthline FindCare tool can help you find a healthcare professional in your area.
You may experience itchy skin at night for various reasons. These can range from changes in skin hydration due to the natural circadian rhythm to bug infestations and underlying health conditions.
This itching can often be severe enough to affect your sleep cycle, impacting your quality of life.
The treatments for itchy skin at night will vary depending on the cause.
