The most humid places on Earth are tropical coastal areas, especially in Southeast Asia, with Balikpapan, Indonesia often cited as the most humid city due to 365 days of extreme humidity yearly, while Dhahran, Saudi Arabia holds the record for the highest measured dew point (95°F), creating near-lethal heat index conditions. Other extremely humid locations include the Philippines, Malaysia, Singapore, Darwin (Australia), and the Persian Gulf coast during summer.
Relative humidity hits 100% in southern China : r/interestingasfuck.
It has been widely believed that a 35°C wet-bulb temperature (equal to 95°F at 100% humidity or 115°F at 50% humidity) was the maximum a human could endure before they could no longer adequately regulate their body temperature, which would potentially cause heat stroke or death over a prolonged exposure.
100% humidity is not possible as the air is completely saturated and water droplets fall out. The maximum a weather station will measure is 99%. High (and low) humidity are very difficult to measure.
High relative humidity, in excess of 70%, is uncomfortable, and health may be threatened through the development of surface condensation and mould growth. Levels of relative humidity in the range of 40 to 70% are recommended for the workplace environment.
The 30-60% humidity range is considered optimal for year-round comfort. It strikes a balance between dryness and excess moisture, reducing the chances of health problems and property damage.
Yes, your air conditioner does remove humidity from the air. Well-maintained air conditioners help to keep your relative humidity between 30% and 50% — the ideal level. As long as you run your air conditioner regularly enough to keep your home cool, it will also keep humidity levels in check.
Opening windows promotes more airflow, which enhances ventilation inside the building. This guides in eliminating sticky, humid air and supplanting it with drier external air. Ventilation is essential in regions like kitchens, showers, pantries, and other rooms where dampness is delivered.
By this metric, Balikpapan in Indonesia is the most humid, suffering 365.0 humid days and 268.8 extremely humid days per year.
If your house's humidity is consistently higher than 50% or lower than 30%, you could be putting your home — and your health — at risk. If you have too much humidity in your home, you could face harmful mold and mildew growth, and even structural damage.
If the weather is too hot, too cold, too humid, not humid enough, or even too windy, it can feel harder to breathe and you may wheeze or cough more. Research has found that the ideal conditions for people with respiratory disease are a temperature of around 70⁰F and humidity level around 40%.
I work in a dry room. The humidity gets pretty close to 0% (true 0% is pretty much impossible, the same way 100% purity is basically impossible). You can work all day in the dry room and not feel uncomfortable (it is maintained at a nice 70 degrees with excellent air circulation).
In humid conditions, the air becomes populated by hydrogen and nitrogen as well as oxygen, and our lungs have to work harder to get oxygen from the air. This is part of the reason why we feel so lethargic in humidity, and why physical activity can be especially taxing.
Chile. Chile is considered to be one of the driest countries in the world. The northern part of Chile, particularly the Atacama Desert, is one of the driest places on Earth. Retirees can choose to live in Antofagasta or San Pedro de Atacama, which are some of the best places to retire in Chile.
That's right: Alaska is one of the most humid states! In fact, Alaska reports an average RH of 77%, with the next highest state, Florida, reporting a 74% average. Despite Florida being hot and balmy, Alaska has high humidity levels because of its milder, lower temperatures.
The top five most humid cities in the U.S. are:
Balikpapan, Indonesia
Uncomfortable levels of humidity occur on no fewer than 365 days a year, a number that far outshines anything Europe can muster. And that's not the worst of it. For a full 268.8 days of the year, the humidity reaches extreme levels.
Having lived for substantial periods in both, Houston (for example) gets several degrees hotter than New Orleans. Seems like 5 degrees hotter. But New Orleans has substantially higher humidity. So you're basically looking at broiling or steaming.
"Lüften works simply by manually opening your windows either in the morning or in the evening to release an excess build up of carbon dioxide, mold, bacteria, allergens or condensation, while also allowing oxygen back into the interior environment," Riddei says.
Use exhaust fans in bathrooms and kitchens to remove moisture to the outside (not into the attic). Vent your clothes dryer to the outside. Turn off certain appliances (such as humidifiers or kerosene heaters) if you notice moisture on windows and other surfaces.
Mold needs 55% or higher humidity in order to grow. Also, remember that reducing humidity below 30% isn't a good idea, either.
The 3-minute rule is a simple but important guideline: wait at least three minutes after turning your air conditioner off before turning it back on. That short pause gives the refrigerant pressure in the system time to equalize.
If the temperature is set to 74°F but the thermometer shows 78°F, you will have to recalibrate the thermostat to account for this 4-degree deviation. Even with older AC units or furnaces, you might have to recalibrate your thermostat from time to time.
Dehumidifiers can have many benefits around the home, especially if you live in areas of high humidity or, like much of Australia currently, high rainfall is causing moisture build-up within the home. But if you own an air conditioner, it can be as effective at dehumidifying a room as a dehumidifier.
