Room Temperature App Download

Colloquially, room temperature is a range of air temperatures that most people prefer for indoor settings. These temperatures feel comfortable to people wearing typical indoor clothing. Human comfort can extend beyond this range depending on humidity, air circulation and other factors.

In certain fields, like science and engineering, and within a particular context, room temperature can mean different agreed-upon ranges. In contrast, ambient temperature is the actual temperature, as measured by a thermometer, of the air (or other medium and surroundings) in any particular place. The ambient temperature (e.g. an unheated room in winter) may be very different from an ideal room temperature.

In the recent past it was common for house temperatures to be kept below the comfort level; a 1978 UK study found average indoor home temperatures to be 15.8 C (60.4 F) while Japan in 1980 had median home temperatures of 13 C (55 F) to 15 C (59 F).[11]

Rooms may be maintained at an ambient temperature above the comfort temperature in hot weather, or below it in cold weather, if required by cost considerations or practical issues (e.g. lack of air conditioning or relatively high expense of heating.)

The World Health Organization in 1987 found that comfortable indoor temperatures of between 18 and 24 C (64 and 75 F) were not associated with health risks for healthy adults with appropriate clothing, humidity, and other factors. For infants, elderly, and those with significant health problems, a minimum 20 C (68 F) was recommended. Temperatures lower than 16 C (61 F) with humidity above 65% were associated with respiratory hazards including allergies.[12][13]

The WHO's 2018 guidelines give a strong recommendation that a minimum of 18 C (64 F) is a "safe and well-balanced indoor temperature to protect the health of general populations during cold seasons", while a higher minimum may be necessary for vulnerable groups including children, the elderly, and people with cardiorespiratory disease and other chronic illnesses. The recommendation regarding risk of exposure to high indoor temperatures is only "conditional". Minimal-risk high temperatures range from about 21 to 30 C (70 to 86 F) depending on the region, with maximum acceptable temperatures between 25 and 32 C (77 and 90 F).[14][15]

Temperature ranges are defined as room temperature for certain products and processes in industry, science, standards, and consumer goods. For instance, for the shipping and storage of pharmaceuticals, the United States Pharmacopeia-National Formulary (USP-NF) defines controlled room temperature as between 20 and 25 C (68 and 77 F), with excursions between 15 and 30 C (59 and 86 F) allowed, provided the mean kinetic temperature does not exceed 25 C (77 F).[16] The European Pharmacopoeia defines it as being simply 15 to 25 C (59 to 77 F), and the Japanese Pharmacopeia defines "ordinary temperature" as 15 to 25 C (59 to 77 F), with room temperature being 1 to 30 C (34 to 86 F).[17][18] Merriam-Webster gives as a medical definition a range of 15 to 25 C (59 to 77 F) as being suitable for human occupancy, and at which laboratory experiments are usually performed.[19]

Thermal comfort is not universal everywhere, and it even varies among people of different sexes and ages within the same geographic designation. Generally speaking, however, indoor temperatures in the Western world are often set somewhere in the range of 68 to 74 degrees Fahrenheit, depending on the season; in sub-Saharan Africa, however, many people prefer a temperature closer to 79 degrees Fahrenheit.

Even more critically, temperature influences the structure of emulsions such as vinaigrettes and mayonnaise, which are unstable by their very nature. (This is why commercially produced mayo and vinaigrettes usually contain a stabilizer such as lecithin.) As a science class reminder, an emulsion is a mixture of two incompatible liquids, such as oil and water, where one is dispersed as droplets throughout the other. At room temperature, the ingredients in the emulsion are more fluid and less viscous. This makes it easier to blend the two components together, facilitating a more thorough and even mixing process. Cold liquids, on the other hand, can be thicker and more resistant to blending, making it harder to achieve a stable emulsion. Likewise, warm liquids often make emulsions more susceptible to breaking, as the dispersed droplets start to coalesce and separate.

Beyond that, however, bakers also refer to a concept known as Desired Dough Temperature (DDT), which refers to the ideal temperature of yeasted dough during mixing and kneading. Think of DDT as the "sweet spot" for your dough's temperature, which is usually between 75 to 78 degrees Fahrenheit. If the dough is too cold, it will ferment slowly, taking a long time to rise and develop flavor. On the other hand, if the dough is too warm, it will ferment too quickly, leading to undesirable results like an overly airy or uneven texture.

Room temperature plays a role in determining the initial temperature of the dough before any mixing or kneading occurs. If the room is warm, it can warm up the ingredients, making the dough warmer from the start. If the room is cold, the dough will start off cooler. To achieve the desired dough temperature, bakers often need to adjust the temperature of their ingredients. They might use warmer or colder water to mix the dough, depending on the room temperature and the desired outcome. By controlling the dough temperature, bakers can better manage the fermentation process.

You can calculate DDT the long way, which will help you get a better understanding of how the temperature of your room and other ingredients will impact your final dough, or you can use an online DDT calculator as a shortcut.

For solid ingredients like butter or cream cheese, use a microwave to gently warm them up. Cut blocks into smaller pieces, place them on a microwave-safe plate, and microwave in short bursts (5 to 10 seconds) until softened to room temperature, being careful not to melt them.

It is rarely necessary to keep your heating on all night, and adding an extra layer will usually help. Remember not to add a hat to your baby when they are indoors, as their head is important for

maintaining their body temperature by releasing heat.

One last thing to remember: If a recipe calls for room-temperature butter, make sure your other ingredients, namely eggs and any liquid dairy like milk or cream, are also room temperature. Because if cold eggs hit soft butter, the butter will immediately firm up and the final texture won't quite be the same. While it might feel like a bummer to have to wait patiently for your ingredients to temper, it's a good habit in baking (and in cooking, and in life) to get yourself organized and set up well in advance. And if you have a craving to bake and you absolutely can't delay, make brownies, olive oil cake, or any number of other recipes where you can just dive right in.

On the outer packaging of pharmaceutical products one often finds labels with storage requirements like, for example, "ambient", "room temperature" and "cold chain". But what do they exactly mean? And do these conditions also apply during transport?

So, as a resume, terms like "ambient", "room temperature" and "cold chain" should be avoided as the only labelling for storage or transport boxes and containers because they are not always clear and might have different meanings in other parts of the world. Storage conditions are always better explicitly specified in terms of a defined temperature range (e.g., 15C -25C or +2C to +8C). Particular attention should be given to avoiding freezing of liquids and semi-solids.

Background: This pilot trial focused on feasibility and safety to provide preliminary data to evaluate the hemostatic potential of cold-stored platelets (2 to 6C) compared with standard room temperature-stored platelets (20 to 24C) in adult patients undergoing complex cardiothoracic surgery. This study aimed to assess feasibility and to provide information for future pivotal trials.

Methods: A single center two-stage exploratory pilot study was performed on adult patients undergoing elective or semiurgent complex cardiothoracic surgery. In stage I, a two-armed randomized trial, platelets stored up to 7 days in the cold were compared with those stored at room temperature. In the subsequent single-arm stage II, cold storage time was extended to 8 to 14 days. The primary outcome was clinical effect measured by chest drain output. Secondary outcomes were platelet function measured by multiple electrode impedance aggregometry, total blood usage, immediate and long-term (28 days) adverse events, length of stay in intensive care, and mortality.

Results: In stage I, the median chest drain output was 720 ml (quartiles 485 to 1,170, n = 25) in patients transfused with room temperature-stored platelets and 645 ml (quartiles 460 to 800, n = 25) in patients transfused with cold-stored platelets. No significant difference was observed. The difference in medians between the room temperature- and cold-stored up to 7 days arm was 75 ml (95% CI, -220, 425). In stage II, the median chest drain output was 690 ml (500 to 1,880, n = 15). The difference in medians between the room temperature arm and the nonconcurrent cold-stored 8 to 14 days arm was 30 ml (95% CI, -1,040, 355). Platelet aggregation in vitro increased after transfusion in both the room temperature- and cold-stored platelet study arms. Total blood usage, number of adverse events, length of stay in intensive care, and mortality were comparable among patients receiving cold-stored and room temperature-stored platelets.

These are general guidelines for storing human milk at different temperatures. Various factors affect how long human milk can be stored safely. Such factors include milk volume, room temperature when milk is expressed, temperature fluctuations in the refrigerator and freezer, and cleanliness of the environment. 17dc91bb1f
