Do People Lose Their Vision In Low Pressure Weather?
My vision was rather poor a couple of hours ago, hence the reason for this post.
I asked Google AI, the question in the title of this post, and received this reply.
While people generally do not permanently lose their vision due to typical low-pressure weather systems, they may experience temporary blurry or altered vision. This is usually associated with the physiological effects of low barometric pressure on the body or the cold, dry conditions that often accompany such weather.
That would fit the problems I encountered.
Does Dropping Barometric Pressure Make Your Nose Run?
I’m asking this question as my nose is running and the pressure is dropping for tomorrow’s rain.
Google AI told me this.
Yes, a drop in barometric pressure can make your nose run, as it can cause sensitive nerve endings in your nasal passages to react, leading to swelling of the blood vessels. This can result in congestion, a runny nose, and post-nasal drip.
How it happens: When the atmospheric pressure changes, the pressure in your sinuses no longer matches the pressure outside your body. This difference can trigger a reaction in the nasal passages.
Nasal response: The nasal tissues may swell and sinus drainage ducts can become blocked in an attempt to equalize the pressure. This irritation can lead to symptoms like a runny or stuffy nose.
Other factors: This reaction is often more pronounced when barometric pressure changes are sudden or combined with other weather changes, such as rapid shifts in temperature or humidity.
My left eye is also painful.
I also should note, that a very experiences eye surgeon once told me, that I had the driest eyes he’d ever seen.
New Rail Station For Mid Devon
The title of this post, is the same as that of this article on Exeter Today.
These are the first two paragraphs.
Devon is set to benefit from a major transport funding boost as the Government today confirmed plans for a new railway station in Cullompton and approved a long-awaited upgrade to the A382 between Drumbridges and Newton Abbot.
The announcement, part of a £92 billion national transport investment programme, includes over £47 million to reinstate passenger services between Portishead and Bristol — and, crucially for Devon, two brand-new stations along the Exeter to Taunton line, one of which will be in Cullompton.
It does appear, that according to its Wikipedia entry, Collumpton station has been a bit on-and-off.
In the October 2021 budget, development funding of £5m was allocated for the reopening of Wellington and Cullompton stations. However, in 2024 the Minister of State for Rail, Peter Hendy, stated that the proposed reopening of Cullompton station would no longer be funded by the UK government. Following the government’s spending review in June 2025, funding was confirmed for the station.
But now it appears to be definitely on.
This Google Map shows, the railway and the M5 passing Collumpton.
Note.
- The M5 runs North-South across the map, with Junction 28 about half-way.
- North-west of the junction are Collumpton Motorway Services.
- The Bristol-Exeter Line runs North-South to the West of the services.
This second Google Map shows the Northern end of the services.
Note.
- Parking at the services appears rather limited.
- Trucks seem to be parked at the Northern end of the services.
- I feel there would be space to put a platform on either side of the rail lines.
- I doubt a bridge with lifts would be a problem.
- The station could share the facilities of the services.
- Could some of the fields to the West of the railway be used to create parking?
- The station could be built to accept nine-car Class 802 trains.
Collumpton station could be built to have a high capacity and direct access to the town and the M5.
I have some thoughts.
Could Collumpton Station Function As A Parkway Station?
I believe it certainly could for Exeter, Bristol and even London.
In Darlington Station – 26th June 2025, I showed how Network Rail are creating a 650-place car park at the station, which could be a major draw for travellers.
Could a large car park be provided here to attract travellers?
South West Rail Resilience Programme
This is the first paragraph of this article on Modern Railways.
The Government has paused the third phase of Midland main line electrification to Sheffield and Nottingham, plus the final phase of the South West Rail Resilience Programme (SWRRP), which involves strengthening cliffs at Holcombe.
If the final phase of the South West Rail Resilience Programme is paused, what happens if God decides to block the line through Teignmouth.
I have thought for some time, that one of the purposes of Okehampton Interchange station is to provide an alternative route to the South-West.
If the sea should destroy the coastal railway, as it did a few years ago, then passengers for the South-West could be ferried to and from Okehampton Interchange station by high-speed hydrogen-powered coaches along the A30, to catch trains to Exeter and London.
So, I would build a hydrogen filling station at Collumpton services, so that if the sea destroys the coastal railway again, the alternative of hydrogen coaches is ready.
If Okehampton Interchange station can also be used as an alternative, two alternatives might just ensure that the alternative routes never need to be used.
A Thought On The Texas Floods
I asked Google AI, if Texas is bad for natural disasters.
This was the reply.
Yes, Texas is known to be susceptible to a high number of natural disasters, particularly when compared to other states in the US. Texas experiences a wide variety of natural hazards, including hurricanes, floods, wildfires, tornadoes, hail storms, sinkholes, and droughts. The state has also experienced earthquakes, potentially linked to the extraction of natural resources like oil and gas.
I certainly wouldn’t want to live there, as my one experience of a bad storm in the UK nearly killed me. I wrote about my experiences in The Great Storm.
Do Animals Lose Water In Low Pressure Weather?
I feel I do and I wrote a post called My Strange Skin, which is explained by water being driven out of my body.
So I asked Dr. Google, the question in the title of this post and got this answer.
Yes, animals can lose more water in low-pressure weather conditions. Lower atmospheric pressure, often associated with unstable weather, can increase water loss through evaporation and other physiological processes.
Here’s why:
Low pressure often means lower relative humidity, which increases the vapor pressure deficit between the animal’s body and the environment. This difference in water vapor concentration drives more water to evaporate from the animal’s body, particularly through the skin.
That’s all very sound physics.
Last night, I was woken by an intense strange itch in the sole of my right foot.
- As I often do, I rubbed the itch on the a genuine Indian rug I have on the floor by my bed, but it didn’t work.
- So I had to get up and apply a dollop of Udrate cream and rub it in.
About, half-an-hour later I got back to sleep.
Today, I got a similar intense itch in the sole of my left foot. Again it was stopped by a dollop of cream rubbed in. But this time it was Body Shop’s Hemp Foot Protector.
Does water find it easier to get out through the soles of my feet?
Exceptionally Low River Levels Raise Fears Over Water Supplies
The title of this post is the same as that of this article on the BBC.
This is the sub-heading.
Many of the UK’s rivers have hit exceptionally low levels and that could worsen in the next three months, according to the Centre for Ecology & Hydrology (CEH), raising questions over supplies to households, farmers and businesses.
These three introductory paragraphs add more details.
The warning comes after the driest spring in England since 1961, with northern regions experiencing the driest start to the year in nearly a century.
Almost all of the UK is expected to have below normal or low river levels in May, apart from the south-west of England.
The Environment Agency has said that the UK is at medium risk of drought and warned households of the risk of water restrictions.
In the 1970s, I was involved in a marginal way, in the planning of the water supply network in the UK, by the then Water Resources Board. My software called SPEED was used to solve the hundreds of differential equations involved.
Since the 1970s, I have felt, that as water supply in the UK has been fairly good, that the engineers, planners and mathematicians of the Water Resources Board didn’t do a bad job.
I don’t think, I can remember a period as long as this without rain.
I am drinking heavily to keep hydrated and I’m already today on my second bottle of Adnams Ghost Ship 0.5 % Beer.
But it just seems to go straight out through my skin, which I talked about in My Strange Skin.
I am Jewish in my father’s male line and Huguenot in my mother’s, so I have lots of ancestors, who lived in poor living conditions. So did Darwinian selection produce my leaky skin, that also heals itself quickly, in the harsh living conditions.
But on the other hand does it make me dehydrated all the time? And also create lots of red spots all over my body?
It’s not something new, as I can remember feeling this this as a child and helping my mother to count all the spots.
I hope that I will be fine, when we get some rain.
Drinking And Me
Today, I got up at five and was able to drink my morning cup of tea very quickly.
In fact, I’ve been drinking cups of tea all day at a fast speed.
I’ve also drunk two bottles of Adnams 2.5 % alcohol Ghost Ship beer at a fast pace.
But on other days, I pour a lot away, as I just can’t force it down.
Is it the weather, as it is rather unusual today?
A Funny Turn On Thursday
Because of my endoscopy at five on Thursday, I had a quiet day. I wasn’t allowed to eat anything for eight hours before or drink anything but water for four hours.
About one in the afternoon, I was sitting at my computer, typing a post into my blog.
And then everything, went rather fuzzy and words were coming out garbage. Often each letter was replaced by one of the next on the keyboard.
I was also a bit unsteady on my feet and as I was alone in my house, I decided to go out, so that if it was something worse and I collapsed, there would be someone to help me.
As I got to the bus stop, which is about fifty metres away, a violent thunderstorm broke out.
On the bus to The Angel, I tried to check my phone to get the time. It didn’t respond and I couldn’t unlock it. And even with help from the EE Shop and a guy on the bus, the phone wouldn’t respond to my fingers.
At the Angel, I did at least have a sensible conversation with an assistant about a clothes purchase, but in the end I bought nothing.
I left the Angel earlier than I’d intended and as I was on a 38 bus, which starts my journey to Homerton Hospital, I gave up on the idea of going home for some water.
I had a long change at Dalston Junction for the 242 bus for the hospital, but at least the rain had stopped somewhat and I was by now steady on my feet.
My phone was also working, so I was able to read the instructions about where to go at the hospital.
So what had happened to me at one in the afternoon?
Was there a low pressure before the storm, that sucked all the water out of my body and in the process made my fingers dry, so they didn’t work the phone?
Interestingly, I lost 0.9 of a Kg between 08:00 on Thursday and 08:00 on Friday. Was that just the fasting?
My INR also dropped from 2.4 at 08:00 on Thursday to 2.0 at 08:00 on Saturday. Was that because of all the fluid I lost, thickened my blood?
A Very Bad Night’s Sleep
Last night, I must have woke several times in the night, before I finally gave up at about three-thirty and got up and started doing the puzzles on the Internet, and having some mugs of tea.
At four I went back to bed and was able to grab perhaps thirty minutes of sleep.
But my body hurt all over with a vengeance.
- There was pain in the back of my left hand.
- My toes hurt badly.
- My right hip was painful.
- All my skin felt very dry.
So at five, I decided to get up and have the cure-all remedy, which is a deep hot bath.
It certainly worked and I felt a lot better,
After the bath, I got back in bed, and although I didn’t sleep, I rose and left the house soon after nine to get my gluten-free breakfast in Leon on Moorgate, with added tea and orange juice.
As I left the house, I noticed that one of the upstairs windows was open, so I had to go back and shut it.
As I never open this window, I thought it must have been the cleaners, who’d left it open. Especially, as it had happened before, a couple of weeks ago.
But then, I realised what had happened.
- The window hadn’t been properly secured.
- Last night, a storm with a low-pressure area had gone through..
- The pressure had just been low enough to pop the window open.
- The low-pressure had then just sucked the water out of my body.
My hot bath had put the water back in, the way, that it had come out.
After breakfast and picking up a prescription from Boots, I took a bus home.
On arriving home, I needed to have a poo, but was unable to go, as I was just too constipated.
After a laxative and several drinks, that problem was cured.
Conclusion
Were all my problems today, down to the fact that the weather stole my body’s water and I didn’t drink enough to put it all back?
Are Bodies Cleverer Than We Think?
Because, I had a serious stroke thirteen years ago, I am on Warfarin for life to thin my blood, so that I don’t have another stroke.
INR is short for International Normalized Ratio, which diverts on Wikipedia to the Wikipedia entry for Prothrombin Time, where these is the first two paragraphs.
The prothrombin time (PT) – along with its derived measures of prothrombin ratio (PR) and international normalized ratio (INR) – is an assay for evaluating the extrinsic pathway and common pathway of coagulation. This blood test is also called protime INR and PT/INR. They are used to determine the clotting tendency of blood, in such things as the measure of warfarin dosage, liver damage, and vitamin K status. PT measures the following coagulation factors: I (fibrinogen), II (prothrombin), V (proaccelerin), VII (proconvertin), and X (Stuart–Prower factor).
PT is often used in conjunction with the activated partial thromboplastin time (aPTT) which measures the intrinsic pathway and common pathway of coagulation.
That is very technical and complicated, but what does it mean practically?
Those on Warfarin to thin their blood are generally supposed to keep their INR between 2 and 3.
I test the INR myself with a Coaguchek meter from Roche and have done so for nearly ten years.
Every, so often, I discuss the level of Warfarin with my GP and we adjust the level accordingly.
Typically, NHS patients on Warfarin have their INR checked every few weeks.
But as I am a Graduate Control Engineer, who has written control strategies for chemical plants, I feel this checking every few weeks, is not enough.
At times, I have checked at a higher frequency.
Four times, I have had minor operations.With the first operation, I agreed with the surgeon, that I would lower my INR to 2.1 for the operation and raise it back to 2.5 after the operation.
It all went well and I repeated the exercise for the three other minor operations.
I have checked daily since about the beginning of April, before which, I generally tested on Mondays and Thursdays.
There were two reasons for the change of frequency.
- Regular storms seemed to roll in and for some reason, they tended to lower my INR.
- I also wrote Do Thunderstorms Cause Strokes?, after reading a paper from the United States about the relationship between thunderstorms and strokes.
So I took the prudent decision to test my INR daily.
Then on the 30th May, disaster struck.
My Coaguchek meter found out it had the wrong firmware and Roche implored me to change it.
But I am not a hardware person, so I was left unable to check my INR.
Luckily, I remembered a story from the 1960s about one of ICI’s chemical plants.
This plant was one of the first fully-digitally controlled plants controlled by an IBM 1800 computer.
It also ran 24 hours a day, seven days week.
So in the middle of the night, the plant operators got out all the computer printouts, which showed how the computer had set all the valves and controllers.
One-by-one they reset all the controls on the plant to the settings that the computer had used for the last few days.
Using, this computer-assisted mode the plant was kept running, until engineers could fix the computer.
On the 30th May, my INR was a little bit high at 2.9 and I was using a dosage of Warfarin of 4 mg. one day and 3.5 mg. the next.
The strange dosage was one, that I know from experiment over time produces an INR of 2.5.
My actual average Warfarin dose was 3.73 over the last thirty days and my INR, as measured most days was 2.6 over the same period.
So, I did what the engineers did on the chemical plant, kept calm and carried on.
Yesterday my son fixed the Coaguchek meter and I was able to take my first reading for 17 days. It was 2.7 and only 0.1 higher than the 30-day average on the 30th May.
I had successfully jumped the gap in the readings.
Conclusion
Most systems have an equilibrium. Make sure you know it.
