Surprise, You Are a Weather Station!

Well, your body is a weather detector anyway…

Can you read the signals and signs your body is telling you?

Sure you can:

Sometimes you know what the weather is going to be before you even open your eyes in the morning. You not only pay attention to every detail of your environment but you always do something about it. Every second of every day for your whole life!

Read on and discover why you get headaches when it rains.

Just as you can see what you look like with a mirror, a home weather station can reflect the conditions your body is adapting to.

Looking at the temperature in terms of degrees and wind speed in terms of miles per hour comes naturally. But…

…Measurements of humidity and pressure do not have the same easy relationships in everyday life as temperature and wind speed do.

A home weather station can certainly help with this.

What can you learn about yourself with a weather station?
There is a field of study called human biometeorology. There’s a mouthful! This field brings various scientists, medical experts, and meteorologists together.

Human Biometeorology is a subfield of Biometeorology that studies the impacts of weather and climate on human health. Biometeorology is an interdisciplinary science that examines the interactions between atmospheric processes and living organisms, including plants, animals, and humans. Human Biometeorology is a part of Biometeorology that deals with the study of weather and climate impacts on human health. Ongoing research in this field involves studying how different weather conditions can affect human health, such as heat stress and air pollution. By understanding how weather and climate influence human health, we can gain insight into how to make our environment more conducive to healthy living.

Well, they have discovered a few things…

 1. Temperature…   As the temperature rises,  blood vessels expand and your blood pressure goes down. Good news! If you have high blood pressure, staying warm is a good idea. Just make sure to drink enough water though.

As temperatures go down, blood vessels constrict and blood pressure rises. While this will help maintain internal body temperature, your body has to remove water from the blood to compensate. This causes the blood to get thicker. Not so good news. Puts more meaning in a thermometer reading, doesn’t it?

2.  Humidity... This is usually expressed as relative humidity; a measure in % of how much water the air can absorb. As the humidity goes up, sweating becomes less efficient and you feel hotter than it really is, and as the humidity goes down you feel cooler.

If you have problems with temperature, pay attention to the humidity too. If the conditions are too humid or too dry, get a dehumidifier or humidifier and do something about the weather!

 3. Wind chill…This is a measure of the effect of air movement on your epiclimate. My WHAT! When there is no wind, a layer of air, that could be warmer or cooler than the thermometer reads, forms around your body.

On a warm, calm day, your epiclimate could be even warmer and any air movement is cooling and refreshing. On a cold day, it goes the other way; you want to keep your epiclimate right where it is. More than modesty, this is what clothing is really for!

 4. Dewpoint… The question “What is dewpoint?” comes up a lot. The dew point is the temperature where dew forms. And where clouds and fog form. It is the point where the air is completely saturated and cannot accept any more water. This is a problem on warm days when perspiring is supposed to cool you off. This is why the dew point is considered the best measure of comfort in warm weather, even more so than the temperature.

The amount of water vapor the air can hold at a given pressure and temperature is a known and fixed amount. Warmer air holds more water than cooler air.

Here is a mental illustration: imagine two water glasses, one twice the size of the other. These glasses represent the temperature and water capacity of the air. Call the smaller glass 40° and the larger 80°. See where I’m going with this?

Now fill each glass halfway; this represents 50% Relative Humidity. Relative to the size of the glass, which represents our temperature. But the amount of water in each glass is different. The amount of water is called Absolute Humidity, and this is what the dew point is all about.

The amount of water in the 80° glass would exactly fill the 40° glass. Our 80° glass would have a relative humidity of 50% and an absolute humidity, the dew point, of 40°. Our 40° glass also has a 50% R.H. but a dewpoint of 20°, which would be called the ‘frost point’, where frost forms.

Barometric pressure plays a part; when the pressure falls things expand. This includes the water vapor in the air. If the pressure drops and you are near the dew point it might be enough to “overfill” your glass.

So, you can see the problem; when it’s cooler out you can dress warmer, but when it gets warmer and more humid at some point your body has no way of cooling off. Sweating eventually doesn’t work. This can be dangerous to people and animals who cannot find a way or a place to cool off.

Everybody is different and comfort is somewhat subjective, but this is the general idea of dew point comfort levels:

  • Less than 50° is quite nice
  • Between 50° and 55° is very comfortable
  • Then around 56° to 60° it starts to feel humid
  • Around 61° to 65° it feels decidedly sticky
  • Up from 66° to 70°, it gets noticeably uncomfortable
  • At 71° to 75° the humidity is downright miserable
  • Over 76° the dew point is dangerously high

Oh, and did I mention mold loves heat and humidity…..

5.  Wind…While a bit of wind on a warm humid day is very welcome, a wind in very dry conditions just makes you dehydrate faster. Winds are usually associated with a low-pressure area, so separating the health effects of wind and pressure is difficult.

The obvious problems are pollen and dust. A not-so-obvious effect is the wind changing the positive/ negative ion mix. An increase in positive ions has been related to numerous problems like migraines, nausea, irritability, slowed reflexes, fatigue, diminished vision, and respiratory problems.

If any of these problems apply to you, consider an air filter or an ion generator. Not all winds are the same; Foehn winds like the Santa Ana, and the Chinook have been associated with loss of wellbeing.

6.  Rain… There is nothing like a good rain to clean the junk out of the air! Another overlooked benefit is raindrops release negative ions when they impact the ground. Crashing waves at the beach and waterfalls in the mountains also have these beneficial effects. You’ll also notice that rain makes you sleepy.

7.  Barometric pressure… The rise and fall of the barometric pressure affect your blood pressure; lower atmospheric pressure results in lower blood pressure. As the pressure falls tissues and gases in your body expand and this is what causes the majority of health complaints. Many people ask: why do I get sinus headaches when it rains? They are sometimes called ‘barometric headaches’ or ‘pressure headaches’.

If the barometer changes slowly, no problem. Rapid changes, particularly down, lead to headaches, joint pain, migraines, and sinus issues. There is not much you can do about the barometric pressure other than be prepared for the issues it causes you.

Why do I get headaches when it rains?

Some people experience headaches when it rains due to changes in atmospheric pressure. As the air pressure fluctuates, it can cause blood vessels in the head to constrict or dilate, leading to headaches. Paying attention to weather information from a home weather station and observing your body’s responses can help you understand why you feel the way you do during rainy weather.

How can a home weather station help me understand my headaches during rainy weather?

A home weather station can provide you with real-time data on atmospheric pressure, temperature, humidity, and other weather conditions. By monitoring these factors and observing your body’s responses, you can gain insight into how weather changes affect your headaches and potentially plan accordingly to minimize discomfort.

What other factors can influence headaches during rainy weather?

In addition to changes in atmospheric pressure, factors such as temperature, humidity, and wind velocity can also influence headaches during rainy weather. Monitoring these factors with a home weather station can help you better understand the relationship between weather conditions and your headaches

How can I use a home weather station to predict when I might experience headaches during rainy weather?

By observing the data from your home weather station and noting how your body responds to different weather conditions, you can start to identify patterns and correlations between specific weather changes and your headaches. This information can help you anticipate when you might experience headaches during rainy weather and take preventive measures or plan accordingly.

Can a home weather station help me understand the behavior of people and animals around me during rainy weather?

Yes, a home weather station can provide valuable information about the weather conditions that may affect the behavior of people and animals around you. By observing the data from your weather station and noticing how others respond to different weather conditions, you can gain a better understanding of their behavior and potentially predict how they might react during rainy weather

Weather is Interesting!

Having your own personal weather station can open up a new understanding of the world. Paying attention to the information from your weather station and your body’s responses will give you insight into why you feel the way you do and maybe some understanding of the behavior of people and critters around you. By using your long-range weather forecast along with your knowledge of how the weather affects you and others, planning for the future can be a lot more meaningful.
