Short answer
Pilea peperomioides leaves typically droop when the plant is either overwatered or severely underwatered. The most common fix is to check the soil moisture; if the top inch of soil is dry, water thoroughly, but if the soil is soggy, allow it to dry out completely before resuming a regular schedule.
Drooping or wilting leaves in a Pilea peperomioides are a very common occurrence, often serving as the plant's way of communicating stress. While it is rarely a sign of immediate death, it is a clear indicator that your current watering routine or environmental conditions need adjustment.
Pilea prefer to dry out slightly between waterings, but extreme dehydration causes leaves to lose turgor pressure and flop. Conversely, waterlogged soil leads to root rot, which prevents the plant from absorbing water even if the soil is wet.
Check: Check the soil moisture level with your finger; if it is bone dry down to two inches, it needs water, but if it is damp and the leaves are soft, root rot may be starting.
Fix: Establish a rhythm where you water only when the top inch of soil is dry, ensuring the pot has drainage holes to prevent standing water.
While Pilea are adaptable, they struggle in low light, which can cause the plant to weaken and exhibit drooping foliage. When the light is too dim, the plant cannot photosynthesize effectively, leading to loss of structure.
Check: Observe the stems; if the plant is leaning significantly toward a window or appearing 'leggy' with wide gaps between leaves, it is craving more brightness.
Fix: Move the Pilea to a spot with bright, indirect light and rotate the pot regularly to keep the stems sturdy and upright.
Pilea are sensitive to sudden shifts in temperature, such as cold drafts from windows or direct exposure to heater vents. This stress manifests quickly as sagging or curling leaves.
Check: Check if your Pilea is placed near an air conditioner, drafty door, or a direct heat source, as these spots cause rapid moisture loss and stress.
Fix: Relocate the plant to a stable environment away from extreme temperature fluctuations and drafts.
When to worry
If the drooping is accompanied by yellowing leaves, a foul smell from the soil, or blackened stems, you should act immediately as these are signs of advanced root rot which can be fatal.

Diagnose my Chinese Money PlantNo, misting does not address the underlying watering or light issues and can sometimes lead to fungal problems on the leaves. Focus on correcting soil moisture and light exposure instead.
Yes, if the wilting is due to underwatering, the leaves will usually recover their turgor pressure within a few hours to a day after a thorough watering.
It is natural for the oldest, bottom-most leaves on a Pilea to yellow and drop off as the plant matures. If this happens slowly, it is just normal aging rather than a watering issue.
