Why do people with hypermobility or dysautonomia crash after feeling better?

Crashes often happen because the nervous system is temporarily supported by adrenaline rather than true energy capacity. When that short-term support fades, symptoms can rebound hours or days later, especially in sensitive or hypermobile bodies.

Is sleep the main cause of low energy in hypermobility or POTS?

Sleep problems are common in hypermobility and autonomic conditions, but sleep alone is rarely the sole cause of low energy. Sleep stability helps reduce nervous system stress and supports recovery, but it does not replace individualized medical care.

Is it safe to rebuild energy with exercise if I have dysautonomia?

For some people with dysautonomia or POTS, carefully paced and consistent activity may help over time. Pushing too hard or changing routines too quickly can worsen symptoms, so gradual, individualized approaches are safer.
