Long Covid fatigue is also associated with Post Exertional Symptom Exacerbation or PESE. PESE means that activities, which pre-COVID you might have considered easy, can now lead to periods of extreme fatigue. Something as simple as taking a shower, going for a walk or even working at a desk may make you feel extreme exhaustion either immediately or even a day or two later.
PESE can also cause other symptoms to flare up, such as pain, brain fog, shortness of breath, palpitations or disturbed sleep. Nearly 75% of people with
Long Covid still experience PESE after 6 months.
