This generates heat that can dry out the internal electrolytic materials in the capacitor which causes a decrease in the capacitance. It can also increase the series
Capacitors are also rated for "ripple current" and exceeding the ripple current rating will increase internal heating and reduce lifetime. This is an additive effect with temperature. eg If two

Heat can impact the performance and lifespan of capacitors, especially in the most challenging applications such as induction heating. Murray Slovick reviews the science behind keeping capacitors cool and looks at some ways that capacitor technology could revolutionize cooling elsewhere.
There are many other methods to remove capacitor heat. Some are as simple as ensuring a good conduction path between the closed end of the part and a large thermal conductor. Folded fin material wrapped around the capacitor and attached with a clamp is another innovative way to increase cooling surface area.
In higher power cases, the larger heat load may require additional cooling by means of an external heat dissipator or heat sink (not unknown, but not common with capacitors since they take up a lot of space); a fan, which can forcefully direct cooling air over the capacitor; or liquid cooling.
High ripple current and high temperature of the environment in which the capacitor operates causes heating due to power dissipation. High temperatures can also cause hot spots within the capacitor and can lead to its failure. Cooling a capacitor helps to enhance its performance as well as its reliability.
The most common cooling methods include self-cooling, forced ventilation and liquid cooling. The simplest method for cooling capacitors is to provide enough air space around the capacitor so it will stay sufficiently cool for most applications. “Most applications,” but not all.
An external heat dissipater, or heat sink, can increase heat removal further, increasing the life of the capacitor. This additional heat sinking can take many forms. The most common heat sink is an aluminum extrusion that attaches to the closed end of the capacitor.
