Hyperthymesia is also known as highly superior autobiographical memory (HSAM). According to a 2017 study, people with hyperthymesia can accurately and readily recall numerous details about events that have occurred in their life. These details can include exact dates and intricate information about previous experiences. Current research suggests that the ability is limited to autobiographical memory. This limitation means that people can only recall information about themselves and their past personal experiences. The causes of HSAM are currently unknown, but some theories suggest that it may have biological, genetic, or psychological origins. There is currently no way to diagnose hyperthymesia formally. Possible ways to assess this may be through MRI scans and complex memory tests. Hyperthymesia differs from eidetic memory in that it focuses on a person’s ability to recall their autobiographical experiences rather than to hold visualizations in their mind. Further research is necessary to examine the differences and similarities between hyperthymesia and eidetic memory.
Cold sores, also known as oral herpes, are small, painful blisters that develop around the mouth. Sometimes, people who develop cold sores will also develop a fever, which is why some people call cold sores fever blisters. They are caused by the herpes simplex virus (HSV). A cold sore is not the same as a canker sore. A canker sore is a small, painful bump that always occurs inside the mouth and is not contagious. It takes 1-2 weeks for cold sores to heal completely. However, according to Harvard Health Publishing, the virus that causes cold sores remains in the person’s body throughout their life. HSV may lie dormant for years and cause no symptoms. In some people, the virus will reactivate and cause cold sores. Between 5-10% who get cold sores get them as frequently as five times a year. Many people contract HSV as children and carry the virus throughout their life. Cold sores may return throughout an individual life, although they can become less severe over time. In most cases, home care and OTC remedies can relieve symptoms and speed healing. Prescription antiviral medications and laser treatment can also help.
This article looks at how histamine affects the body, what histamine intolerance is, and the foods people may wish to avoid. It also provides an example meal plan and tips for grocery shopping and food preparation. Histamine is a chemical that regulates the body’s response to foreign substances and injury. When the body reacts to a substance it perceives as harmful, it releases histamine. This causes inflammation and dilates a person's blood vessels, leading to symptoms such as:
* hives (urticaria)
* runny nose
* watery eyes
Despite the discomfort these symptoms can cause, histamine plays an important and complex role in the body's defenses. A low histamine diet may benefit someone with histamine intolerance. Planning varied meals, avoiding high histamine foods, and allocating time to prepare fresh foods may help a person manage their symptoms. If someone suspects they may have histamine intolerance, it is essential that they consult their doctor for advice. People need to ensure that they do not miss out on essential nutrients when following a limited diet. People should not follow long-term exclusion diets without seeking advice from a registered dietitian or nutritionist.
Iron is a vital mineral with a variety of roles in bodily functioning. It is particularly important in keeping red blood cells healthy. Almost 70% of the iron in the body is located in the hemoglobin. This is a protein in the red blood cells that carries oxygen in the blood from the lungs to other parts of the body. A healthcare professional may prescribe iron supplements if someone does not have enough iron in their body. People can also purchase over-the- counter iron supplements. There are numerous iron supplements available, each containing varying amounts of iron. Although they are typically in tablet form, some are also available as a liquid. Vitamin C helps the body absorb iron more efficiently, so some manufacturers of iron supplements will add vitamin C to the formulation. Iron deficiency anemia is one condition that will require iron supplements. People experiencing less severe forms of iron deficiency due to pregnancy or blood loss may also need to take iron supplements. Taking iron supplements may cause some minor side effects while the body is adjusting. If someone suspects that they have taken too much iron, they should seek professional medical help as soon as possible.
Wisdom teeth can cause various problems. There may not be enough room for them to come through, in which case they may emerge at an angle or never emerge fully. This sets the stage for future problems, such as cavities and infections. Pain and swelling are two common symptoms of a wisdom tooth infection. If these issues last for more than a few days, visit a dentist. The dentist will clean the affected tooth and will likely prescribe antibiotics to treat the infection. They may also recommend extracting the tooth to prevent further issues. If pain, possibly or definitely stemming from an infection, lasts for more than 3-4 days, or if there is swelling in the gums around a wisdom tooth, see a dentist. The dentist will work to identify the cause of the problem and recommend appropriate treatments. Many people delay getting dental treatment until their pain becomes severe or they develop significant swelling. When either happens, emergency care may be necessary.
The most common causes of an itchy throat and ears are allergies, viruses, and infections. However, some environmental factors can also cause itching. The ears, nose, and throat are connected. This means that allergens, viruses, and bacteria can travel between them. Similar membranes line all three, so the same types of infection can affect the throat and ears. Symptoms of a cold or sinusitis could present as an itchy throat and ears. Other symptoms may include a blocked nose and fatigue. Taking OTC medications and drinking fluids can help relieve the symptoms and reduce irritation. If an itchy throat and ears are due to allergies, the symptoms can last longer. A person should see an allergist if the cause of the allergy is not clear or OTC medication is not working.
