Cold all the time... result of training?

Something I’ve noticed now into my 3rd year is by May/June I am feeling cold all the time when not working out - especially below 24c/75f. I’m guessing it’s a result of getting fitter and heat adaptations… besides battling over the thermostat or bundling up, what does everyone else do?

I’ve found it colder than usual on my 5:2 days - i.e very reduced food intake. I think low carb stores in body contribute too. But I guess training and its effects on hormones (e.g thyroid etc) will also affect how you experience temperatures. Plus its been a cold spring in northern europe😊

Under eating? Over training?

I find I keep warmer and feel the cold less when I’m fit and well.

Haha, definitely not under eating, I don’t have a “fit” cyclist body shape/size/weight (Lycra doesn’t lie!). Don’t think I do enough training following the SUF plans (roughly 450 tss/wk) to be “over-trained”. (I think most people are typically in the 1000 tss/wk range?) Resting HR is consistently around 50 bpm and HRV is generally flat week to week and month to month. I’m constantly closing vents and turning the thermostat up to 74 when the AC is on.

450tss of high intensity workouts is still enough to be overdoing it, heck that could be Nine hammers 5 times a week :face_vomiting:. You can still underfuel and not lose weight, our bodies are amazing and all react differently to what we eat.

Roughly eat 2800-3000 cal /day.

Thanks for the questions/suggestions.

I also consulted Dr. Google and Dr. Bing….

  1. HVAC systems can sometimes make it feel like sitting in a cold winter draft even though the ambient indoor temperature is considered room temperature.

  2. 1-3 hours after working out the body is still cooling its self. Once cooled down, the ambient temperature may feel colder.

  3. Heat adaptations and lower body fat percentages can make room temperature feel colder even though everyone else feels comfortable

  4. Other immune system responses including seasonal allergies (:raising_hand_man:) can make the ambient temperature feel colder even though body temperature is “normal”.

  5. Weather can make an impact too - humidity, cloud cover, sunshine on skin, wind…


I found that with training I feel extra cold in the winter. Some likely from fat loss. Also it depends on where I am exercising. If I ride on my trainer on a cold morning I warm up quickly because the room is warm and my body heat and the trainer increase the heat in the room.

But when I run outside when the temp is below 50F, my hands get really cold and painful and I have to wear warm gloves when running, and usually skip outside cycling altogether because my hands lose all feeling and it’s painful. Then when I come back inside my hands are perpetually cold for the rest of the day - despite taking a long a hot shower - and I end up wearing gloves inside even tho the ambient temp is 70F and the heater is running.

In the summer I definitely don’t sweat as often since I got in shape largely likely due to fat loss and improved circulation and heat adaptation.

But I can’t say I get extra cold inside during the summer unless the a/c is turned way down and my clothes are wet.

Like everything else this is probably a very individualized thing as each body may respond differently to all the factors.


And that, right there, is your answer :slight_smile:

Seeing as I live in Australia you’ll all laugh at this, but when I’m fitter and leaner I definitely feel the cold more!
