Serotonin is a naturally produced chemical in the human body. When the body is not producing serotonin a person can start having numerous symptoms. One of the symptoms is depression. This chemical is also known as the "happy chemical" since it affects the mood, happiness, and a person's overall well being.
When the body isn't producing this chemical, people may become hungry and crave sugar, they may have issues with being hot or cold all the time, and have trouble sleeping.
To raise serotonin levels there are several things that can be done. a few of these things are; taking a walk in the sunshine, changing your diet, get a good night's sleep, take vitamin D, and try to lower stress in your life.
This kind of exposure is called caustic exposure.
Explanation:
A caustic exposure is an exposure to chemicals present in common household cleaning products like detergents, cleaning solutions, drain cleaners etc.
These contain caustic substances (strong concentration of acid or base) like sodium hydroxide, sulfuric acid etc. When exposed directly on to the skin, due to its stronger concentration, it may burn the skin causing redness, irritation, numbness, or blackening of the skin surface.
Most of the times, these marks go away after some weeks because they are superficial or first-degree burn where only the epidermal layer of the skin gets affected.

Temperatures above 40°F thru 140°F creates a favorable environment for bacteria proliferation, it's called the danger zone for foods. The recommendations are wether keep the food hot (above 140°F) or keep the food cold (below 40°F).
