Mushrooms have been used by humans for thousands of years, but there is still much to learn about their effects on the body and their temperature regulation. Mushrooms are known to have a hypothermic nature, meaning they can maintain a colder temperature than their surroundings through evaporative cooling. This unique ability has potential applications in passive indoor air conditioning. Furthermore, mushrooms are subject to temperature shock, with heat shock and cold shock procedures being used to trigger the formation of the reproductive organ of the fungus. The effectiveness of temperature shock varies depending on the genetics of the mushroom strain. While the thermal biology of mushrooms is not yet fully understood, their cold nature and potential benefits to human health make them an intriguing subject for further research.

What You'll Learn
Mushrooms are hypothermic due to evaporative cooling
Mushrooms have long been known to be colder than the surrounding air. This phenomenon has been confirmed by recent studies that have found that mushrooms, along with yeast and mold communities, can maintain colder temperatures than their surroundings. This discovery has led to the understanding that mushrooms are hypothermic due to evaporative cooling.
Evaporative cooling is a process by which heat is lost through the evaporation of water. In the case of mushrooms, their high water content and evapotranspiration rate enable efficient thermal energy transfer and water transfer. This process of evaporative cooling is an ancient mechanism of thermoregulation, allowing mushrooms to maintain a hypothermic state.
The hypothermic nature of mushrooms has been observed throughout the entire fruiting process, with the fruiting areas of mycelium being colder than non-fruiting areas. This suggests that the process of evapotranspiration may be regulated by the mycelium itself, causing the fruiting areas to have increased evapotranspiration rates even before the appearance of the first fruiting bodies. The hymenium, or underside of the mushroom cap, is typically the coldest part of the mushroom.
The discovery of mushroom hypothermia has led to innovative applications such as mushroom-based air-cooling systems. These systems utilize the evaporative cooling properties of mushrooms to passively reduce the temperature of enclosed spaces, providing an environmentally friendly alternative to traditional air conditioning. Furthermore, the study of mushroom thermoregulation can provide insights into the effects of global warming on fungal biodiversity and ecology, as fungi play a crucial role in supporting terrestrial life.
In conclusion, mushrooms are hypothermic due to evaporative cooling, a process that has evolved as a mechanism of thermoregulation in the fungal kingdom. This discovery has not only practical applications in indoor air conditioning but also contributes to our understanding of the essential role of fungi in maintaining the balance of Earth's ecology.

Reishi mushrooms may help fight the common cold
Mushrooms are known to be effective in preventing and treating respiratory viruses like the common cold. One such mushroom is the reishi mushroom, also known as lingzhi or Ganoderma Lucidum. Reishi mushrooms have been used for hundreds of years, mainly in Asian countries, for the treatment of infections. They have also been used to treat pulmonary diseases and cancer and have been approved as adjuncts to standard cancer treatments in Japan and China.
Reishi mushrooms have incredible immune system-boosting properties. They are packed with essential amino acids, polysaccharides, and triterpenes, along with proteins, steroids, mannitol, coumarin, and alkaloids. Studies suggest that amino acids can significantly impact immune function, and reishi mushrooms are an excellent source of these compounds.
The beta-glucans found in reishi mushrooms are powerful constituents that can stimulate the innate immune system. Additionally, reishi mushrooms have been shown to reduce stress, improve sleep, and lessen fatigue. They can be consumed in various forms, including capsules, powder, and tinctures, but optimal doses have not been established, and quality and active ingredients may vary across products.
It is important to note that reishi mushrooms may increase the risk of bleeding, especially in individuals with a very low platelet count. They may also interact with certain medications, such as anticoagulants, antiplatelet drugs, and blood pressure medications. Therefore, it is advisable to consult a healthcare professional before incorporating reishi mushrooms into your diet or taking them as a supplement, especially if you have existing health conditions or are taking any medications.

Shiitake mushrooms can help fight the flu
Mushrooms have long been celebrated for their nutritional value and dense structure of vitamins, minerals, and bioactive compounds. However, recent studies have discovered that a component called beta-glucan, found in all mushrooms, can help the body fight the flu.
Beta-glucan is a naturally occurring polysaccharide that enhances the body's defence mechanisms. It is present in the cell walls of all fungi and has been shown to possess immune-stimulating activity. According to research conducted at McGill University in Canada, beta-glucan can help manage flu infections by inhibiting out-of-control inflammation that usually leads to complications. The treated mice subjects had very little lung inflammation, improved lung function, and a very low probability of becoming seriously ill or dying.
The study, published in the journal Nature Immunology, suggests that beta-glucan can help boost immunity, create better disease tolerance, and increase flu survival rates. This is because the flu often triggers an extreme immune response, which is what causes more serious complications, including flu-related deaths. By controlling the severity of the immune response, beta-glucan may be a promising treatment option.
Shiitake mushrooms, in particular, are known for their potential health benefits. They are rich in vitamins, minerals, and antioxidants, which can help support overall health and strengthen the immune system. While further research is needed, shiitake mushrooms may be a valuable addition to flu prevention protocols, helping to enhance immunity and protect against severe respiratory diseases.
In conclusion, shiitake mushrooms, and mushrooms in general, have the potential to be a powerful ally in the fight against the flu. By boosting immunity and controlling inflammation, they can help reduce the severity of flu infections and improve overall health.

Maitake mushrooms have antiviral properties
Mushrooms are known for their hypothermic nature, which is a result of evaporative cooling. This cooling process is an ancient mechanism of thermoregulation. Fungi, which make up approximately 2% of Earth's biomass, contribute to cooler local temperatures through their high evapotranspiration rates.
Maitake mushrooms, scientifically known as Grifola frondosa, are edible fungi with a range of health benefits. They have been used in East Asian traditional medicine and cuisine for centuries, referred to as "hen-of-the-woods" or "dancing mushrooms". Maitake mushrooms are known for their adaptogenic properties, which enhance vitality and strengthen the immune system. They have been used to treat various diseases, including respiratory illnesses, circulatory issues, and even cancer and AIDS.
Maitake mushrooms are particularly renowned for their antiviral properties, which are attributed to the presence of various bioactive compounds. These compounds include polysaccharides, β-D-glucans, ergosterol, lactulose, dextrin, oligofructose, triterpenes, and phenolic compounds. The β-D-glucans, for example, have been linked to anticancer activity and immunomodulatory functions, improving the performance of the immune system. The mushroom also contains acetic acid and malic acid, which provide antibacterial properties.
The antiviral and antibacterial properties of Maitake mushrooms make them an excellent natural remedy for treating respiratory diseases. They can help strengthen the immune system to fight off infections and relieve symptoms. Additionally, Maitake mushrooms possess anti-inflammatory properties, which can further aid in reducing the severity of respiratory illnesses.

Cooking mushrooms helps release nutrients
Mushrooms have been used as a food source and medicine for thousands of years. They are a good source of dietary fibre, protein, amino acids, vitamins (including B1, B2, B12, C, D, and E), and minerals. They are also low in fat and calories. However, the cooking process can affect the nutritional profile of mushrooms.
Frying and boiling mushrooms can lead to a significant loss of protein, antioxidants, and other beneficial compounds. This is likely due to the leaching of soluble substances into the water or oil used for cooking. For example, cooking mushrooms in water can cause water-soluble nutrients like B vitamins and potassium to escape into the cooking water. Similarly, cooking mushrooms in fat or oil can cause the fat-soluble vitamin D to leach out.
On the other hand, grilling or microwaving mushrooms has been shown to preserve their nutritional content. Studies have found that these cooking methods result in higher retention of polyphenols and antioxidant activity compared to frying or boiling. Therefore, grilling or microwaving mushrooms may be the best way to maximise their nutritional benefits.
It is worth noting that mushrooms, like other fungi, have a hypothermic nature due to evaporative cooling. This means that they can help regulate temperature by dissipating heat. This characteristic has potential applications in passive indoor air conditioning.
