Temperature dysregulation
Many people with Long Covid report difficulties regulating body temperature. This can overlap with dysautonomia/PoTS, inflammation, hormonal changes, and sleep disruption. For some people it is one of the most noticeable signs that their nervous system is under strain.
What it can feel like
hot flushes, sweating, or feeling feverish without a fever
chills, shivering, cold hands and feet, or struggling to warm up
temperature swings (hot then cold)
feeling much worse in heat, after showers, or in crowded rooms
symptoms that occur alongside palpitations, dizziness, fatigue, nausea, or headaches
What can help day to day
There is no single approach that works for everyone.
-
Dress in layers so you can adjust easily
Use simple supports such as a fan, cool packs, warm socks, or extra bedding
If night sweats or chills are an issue, keep changes easy (layers, spare bedding nearby)
-
Heat can worsen symptoms for many people, particularly if dysautonomia is part of the picture. You may find it helps to:
keep showers warm rather than very hot
avoid overheated rooms
plan activities for cooler times of day
take breaks when standing for long periods (for example queues)
-
Hydration can be particularly important if you also experience dizziness or PoTS symptoms. Pacing can also help, as temperature changes can be part of wider symptom flares after exertion.
-
If it feels manageable, note any patterns such as:
heat exposure, showers, exertion, time of day
menstrual cycle or hormonal changes
links with poor sleep or symptom flares
