Surviving Heat & Cold with Adrenal Insufficiency

Why does heat feel punishing with adrenal insufficiency while cold can feel just as hard to recover from?

In this episode, we explore why so many people with adrenal insufficiency describe feeling like their internal thermostat is broken. Heat can drain energy fast, trigger dizziness, nausea, weakness, shakiness, and that sudden “washed out” feeling. Cold can feel deeper than it should, linger longer, and leave the body struggling to warm back up.

We break down why temperature regulation can feel so disrupted in:

• Primary adrenal insufficiency (Addison’s disease)

• Secondary adrenal insufficiency

• Tertiary adrenal insufficiency

• Steroid-induced adrenal insufficiency

This episode covers:

• Why temperature regulation is not controlled by one simple switch

• How cortisol helps the body adapt to heat, cold, and physical stress

• Why aldosterone and fluid balance matter even more in primary adrenal insufficiency

• Why heat can hit so hard even when it “isn’t that hot”

• Why cold sensitivity can happen even if you also struggle with heat intolerance

• Why these episodes can feel fine at first and then suddenly escalate

• How poor sleep, illness, emotional stress, exertion, dehydration, and blood sugar swings can lower the body’s threshold

• Why recovery from heat or cold stress can take longer than people expect

We also talk about the real-life impact:

• why showers, errands, warm cars, outdoor plans, and air conditioning can feel unpredictable

• why people with adrenal insufficiency may plan their day around temperature more than others realize

• why this is not weakness, overreacting, or “all in your head”

This episode also includes practical caregiver perspective:

• early warning signs to watch for

• what to do first when someone is overheating

• why cooling quickly matters

• when symptoms may be serious enough to think about the emergency plan

• why caregivers do not need to perfectly label the event in the moment to help effectively

Most importantly, we talk about the bigger picture: temperature dysregulation in adrenal insufficiency is about more than comfort. It reflects real strain across circulation, hormones, fluid balance, and stress response.

If heat or cold affects you differently now, there is a reason for that. And if your body feels like it has less room for error than it used to, you are not imagining it.
