To ask how you survive this cold as an office worker?

You are taking a drug that is causing significant and rapid weight loss from your body. You are very unlikely to be absorbing sufficient nuritirents. At the very least you should be taking a quality high dose vitamin and mineral supplement, you are likely to need much higher than the daily dose because the drug is preventing absorption. You might benefit from taking double dose of spatone / ferrotone, coconut water with honey and lemon juice to replace electrolytes, Mag365 is a good source of magnesium and high doses of vitamin C (Solgar ester C for example), and probably some leafy greens and bone broth. Your body is not getting enough fuel to keep you warm.

Maybe take a look at some of the power greens. https://harrietsbotanicals.co.ke/the-mighty-greens-moringa-spirulina-and-chlorella/

But eating some highly nutritious food might help... eggs, bone broth, chicken, spinach, sprouted seeds, beetroot, carrots, broccoli.

A heated throw costs pennies per hour to run. Just get one. What's going to happen if you do?

You haven't said what the office temperature is.

I haven't read the full thread, but the office is supposed to be at least 16 degrees centigrade www.hse.gov.uk/temperature/employer/the-law.htm. So I would quietly bring in a thermometer and measure it. If it is less than 16 degrees, then they need to do something about the heating.

If above 16 degrees, NHS probably wouldn't want you to bring a heater in from home as that would need to be approved by Estates, in places where I've worked. However you can get jackets and gilets that you can plug into a powerbank, that would keep you warmer, and I would seriously consider one of those if I still felt cold.

I wear a thermal layer and always have an extra jumper or jacket with me, I swear someone needs to make a heated mouse and keyboard. Also nice to have a flask of warm drink, even if its decafe or fruit tea.

We are building services engineers but still our AC is always baltic :P

Could you buy a fan heater for your room at home and an electric blanket and then offer your parents some extra money?

Is it an unreasonable question?

You probably won't be able to use anything that needs to be plugged in when you are at work so focus on clothes, layers, make sure you add a scarf or neck gaiter, fingerless gloves, down gilet, wool or sheepskin insoles in your boots.

A hot water bottle or microwave heat pack is normally possible to use in the office and will help you warm up. I wedge my hot water bottle between my thick outer jumper and my thinner under layers so I really feel the benefit.

Lots of hot drinks, make a flask if you aren't able to access a kettle regularly.

When you leave your desk include a brisk jog up and down the stairs or do some star jumps while nobody is looking to get the blood circulating

I’m on MJ and also freezing all the time. this cold snap is really getting me.
here is how I manage-

I have a hot bath in the morning, to warm my bones. My clothes are on the radiator and I dry and dress quickly to trap my body heat.
thermal tights under trousers, socks and warm boots. Thin strappy vest, thin thermal long sleeved top and thick jumper on top.

if travelling to work, I prepare a hot water bottle and have a radiator warmed blanket for on knee when driving. Gloves and a hat in the car along with thick coat.optional (if have time) warm the car up before I get in by running engine.

i drink hot water though the day, and refill my hot water bottle a few times.

blanket on my office chair. Blanket on my knee.

gilet over jumper when I take my coat off.
fingerless gloves are an option (can still type with them on).

small portable heater right next to me.

if WFH all of the above plus an electric heated fleece blanket wrapped around me at my home desk. I could technically this to the office too.

for me (on MJ) the key is not to get cold in the first place, as I struggle to warm back up. So hot bath gets me toasty and I trap the heat in. When WFH I’ve been known to periodically blast myself with hairdryer under my jumper to warm back up !

I think loosish layers is the way to go, as the warm air gets held between the layers better that way.

Try sheepskin lined socks like these. Can you import your own fan heater, both at home and in the office?

I am cold all the time, I always have been. For me the key is to keep my feet warm. If they get cold there is no warming me back up with just clothes, I need some sort of external heat like a fire, hot water bottle etc. From about Sept onwards its two pairs of socks as standard and then those huge slipper socks on top of that for bed time. I work for the NHS too and often wear fingerless gloves to type.

I keep some old stuff in my car - gloves, woolly hat, and a waterproof thick high viz jacket. Just in case!

I'm on MJ and really feel the cold. I've only lost about 3 stone, if that, but my BMI has dropped from 27.5 to 21.

Our office is a great temperature but sadly I'm only in there once a fortnight. I WFH most of the time and it's freezing. Yesterday the house was below 15C and I couldn't get warm no matter how many layers I wear. In the end I put the central heating on. We tend not to do that during the day as it seems wasteful/expensive but I caved.

I went into the office last week and got a puncture on the way - pothole on a narrow country lane. Luckily the mobile tyre fitter came out within 30 minutes to deal with it, but it did make me think that, if it had happened on the motorway, I would have had to wait behind the crash barrier in my work clothes and would have frozen.

If it is that it seems quite concerning.
Are there longitudinal studies on weight loss drugs?

I think Mounjaro is behind this. I don't know why it is but my male relative who as been on the injections is exactly the same. Freezing cold all the time. Icy cold hands to touch. After running hot all his life. I don't know if it's just the rapid weight loss means your body hasn't had time to adjust or something specific about the way it works. You need a thread specifically about feeling freezing on / after mounjaro I think.
as a side note, I do recommend fingerless gloves if you need to be typing in a office.

I’d want to get myself checked out if I was unable to ever get warm, despite multiple layers, blankets, exercising etc.

I get cold easily. Wool and layers as others have said.

You asked if there were affordable places to buy wool clothes. If you look hard enough you can find in charity shops (though reflecting the high street they are a sea of polyester mainly these days). The men’s section generally has more. Vintage shops also good. And try Vinted though loads of sellers don’t mention the fibre content. But you can search for wool. I just got a great jumper for a tenner.

But given that it’s your health then maybe consider the cost an investment in that. My Smartwool vest was about £40 and is the best thing ever and has lasted years. Decathlon do cheaper merino.

Alpaca socks are transformational. Alpaca generally as the fibres themselves are hollow so once the air in them is warm it really stays trapped.

I find drinking milky drinks warms me more than watery ones. Eating hot food also helps.

I’d also recommend actually talking to both your line manager and your parents. If you’re this bone cold the whole time. Not just assuming. Also, you’re an adult. If your dad won’t put the heating on because it makes him feel uncomfortable , buy a plug in heater and put it in your room.

The heated chair cushion looks lovely. I’m retired now, but used to work in the NHS and well remember cold offices, admin staff are low down the list of priorities. My ex practice manager would have moaned about the cost of the electric of such a rug! She was bad enough about us plugging our phones in, which costs virtually nothing. Odd woman. At home now I have a heated blanket from Lakeland which is bliss.

You don't need to take a break in order to move! You can stand up and walk on the spot while you're on the phone. You can do some leg exercises or circle your ankles while you're sitting. You can shake your arms and stretch.

I move a lot at work but am also outside for much of the day with the indoor heating going off at 11. I feel this is comparable, as I'm moving but in temperatures at least 10c less than yours...

I wear thermal leggings, thermal socks, thermal long sleeved top; then a thick pair of wool or cord trousers, a flannel shirt (maybe a t shirt too, if a chilly day, extra thermal vest if very cold) and a large wool jumper (and a thin merino one beneath the shirt if below 0 all day). Permanently wear a snood and fingerless gloves, massive coat on for outside and sheepskin lined boots. I am genuinely toasty warm outside all day (other than my fingers!). I know you said you are doing layers, but it doesn't sound like enough, or the right sorts! You need to seriously layer up.

People always think I've lost a lot of weight in spring. I haven't! I've lost a genuine 5/6 inches of jumpers and thermal layers... I am never cold.
