Blood pressure variation and weather / temperature

I don't have the answer for that. But I live in Texas and when we have a cold front my BP goes up too. I'm sooo glad I don't live up north.

Dave, I've always known that colder temperatures can be the cause of our blood pressure rising especially in the case of those already susceptible.  It's due to the blood being a bit thicker.  The following extract from the Mayo  will explain it better than I can.  But have you thought that another reason in your case may be stress-related whilst working, especially as you say your BP was so much lower whilst off work and visiting relatives.  Hope the following helps to answer your question but meanwhile watch your salt intake (processed meats are loade with it), try decaf drinks, and exercise:

"Blood pressure generally is higher in the winter and lower in the summer. That's because low temperatures cause your blood vessels to narrow — which increases blood pressure because more pressure is needed to force blood through your narrowed veins and arteries.

In addition to cold weather, blood pressure may also be affected by a sudden change in weather patterns, such as a weather front or a storm. Your body — and blood vessels — may react to abrupt changes in humidity, atmospheric pressure, cloud cover or wind in much the same way it reacts to cold. These weather-related variations in blood pressure are more common in people age 65 and older.

Other seasonal causes of higher blood pressure include weight gain and decreased physical activity in winter."

I expect that this has already been considered by the posters.

Temperaure outside may not affect the internal temperature of the clinic.

If the BP measurements are being taken in a clinic would the body not aclimatise to the internal termperarure of the clinic, therefor, the ouside temperature and humidity may be irrelevant. I am assuming that the body has 'settled down'.

If the BP measurements are taken at home where temperature control may be difficult to control then the BP may vary

No one has mentioned meals. I wonder if BP could vary markedly after a meal while digection is in progress.

Dave, I am SO glad you posted this as I have been having this problem and screaming about it.  YES bp does this with the changing of the seasons.. To make matters worse my Doctor's nurse died in Oct and her daughter age 18 is completely useless, does not do her job well and takes my bp poorly.. making it higher because of her bad habits.. The Dr. sees this and fortunately makes no big deal out of it..  Also because it's winter now, my vitamin D level is down .. no one is told about bp changing with the seasons and most people are NOT aware of this.  Kudos to you my friend for being observent..

I think there are loads of reasons for your BP to spike because invariably that's what it does most, the cold, that's why they tell people with even remotely higher BP not to shovel snow, eating raises it, needing a pee, having been for a number 2, exercise within 20 mins, alcohol, caffeine, and many more, relax for about 10 mins before taking, feet flat on floor and sitting upright, take it 3 times with a couple of minutes in between, and of course don't get anxious as that will raise it faster and higher than anything, so chill and don't worry too much

I don't know what to tell you Dave mine was spiking a couple of months ago up to 199 over 100 I'm on 20 milligrams of Lisinopril twice a day and Atenolol at night Ranexa twice a day and imdur 60 milligrams in the morning for angina. Dr. Just raised my evening Lisinopril from 10 to 20. I was doing okay for a while and tonight it's spiked again out of nowhere. It makes me feel hard to hear and foggy headed. I get really scared but I'm going to have a stroke but I don't want to think that way I live in California. I don't think the weather has anything to do with it or allergy I am stumped. All I know is that I get very anxious because of it and I get very scared I wish I could have an answer for you and I wish somebody could answer what's going on with me the doctor says I have no blockages in my arteries I just have spasms maybe somebody else in this forum could help us. I hate having this don't you? My sinuses get plugged up when my pressure goes up that's weird I have pounding in my ears or my left ear. That's all for now let me know how you're doing.

I'm monitoring my BP.

After a warm bath it's 101/65

Lying on my bed next day, it came down from 150/96

Smoothly To 132/88 over a period of half an hour measuring every 2 minutes.

Sitting on my bed, it jumped up to 145/99

Then lying back again on bed it dropped to 131/86

All of these measurements at a pretty constant pulse rate of 47 to 54 bpm.

Can anyone explain if I have a problem? (I'm aged 65).

I weigh 180Kg which is about 5Kg over what I should be. I stopped alcohol 2 months ago and I'm on a reducing diet. I lost 4Kg over last 2 Months.
