Answer 1

Nope

An endothermic process is any process with an increase in the enthalpy H (or internal energy U) of the system.[1] In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system. It may be a chemical process, such as dissolving ammonium nitrate in water, or a physical process, such as the melting of ice cubes.

Answer 2

But laughter can cause harms that are immediate and related to the dose, the researchers noted.

One woman with racing heart syndrome collapsed and died after a period of intense laughter.

Some other risks were:

1. Protrusion of abdominal hernias — side-splitting laughter or laughing fit to burst.
2. A quick intake of breath during laughing can cause foreign bodies to be inhaled.
3. Trigger for asthma attacks.
4. Incontinence.
5. Headaches.
