Homeostasis refers back to the body’s want to attain and keep a certain nation of equilibrium. The time period was first coined by means of a physiologist named walter cannon in 1926. 

Essentially, homeostasis is the body’s technique of monitoring and maintaining internal conditions, along with temperature and blood sugar, at a strong and solid stage.

Homeostasis refers to the organism’s ability to regulate various bodily processes to maintain a stable and balanced internal state. This process happens mostly without us knowing it.

How is it stored?

Your body has set points for different statesincluding temperature, weight, sleep, thirst, and hunger. When that level is off (in any way, too much or too much), homeostasis will work to correct it. For example, to regulate temperature, you sweat when it’s too hot or shiver when it’s too cold.

Another popular theory of human motivation, known as drive-reduction theory, suggests that homeostatic imbalances create needs. This requires restoring balance to drive people to actions that bring the body back to its natural state. 2

Another way to think of it is like the thermostat in your home. Once placed at a certain point, it works to maintain the internal state at that point. When the temperature in your home drops, your furnace will turn on and heat things up to a preset temperature.

In the same way, if something is out of balance in your body, the body’s reaction kicks in until the set point is reached again. Here’s how basic homeostasis works:

  • Stimulus: stimulus from environmental change drives something out of balance in the body.
  • Receptor: the receptor reacts to the trade by means of informing the management unit.
  • Control unit: the control unit then dictates the changes needed to bring the body back into balance.
  • Effector: an effector receives this information and acts on the desired change.

A negative feedback loop will work to reduce the effect of the stimulus while a positive feedback loop will increase it. In homeostasis, negative feedback loops often occur, as the body often tries to reduce the effects of the stimulus in order to bring the body back into balance. 

Below we are mentioning the famous actor Tom Curise thoughts about Niacin and SSRIs. So, continue to read;

  • Tom Cruise continued to speak out against the use of antidepressants amid the Brooke Shields controversy.

Tom Cruise once criticized Brooke Shields for taking antidepressants after suffering from post-traumatic stress disorder and got into a heated conversation about the same.

Tom Cruise is another actor who has never shied away from speaking his mind and over the years, he has had some memorable interview moments that will go down in history. When he jumped on Oprah’s couch and said he loved Katie Holmes was one, another memorable appearance was when he went to shout about the use of anti-depressants.

Tom Cruise and Brooke Shields star in Endless Love had a public debate in the early 2000s and it was when the Top Gun: 

Maverick star supported his Scientology beliefs that he called out the actress for his use of Niacin anti-depressants while dealing with post-traumatic stress disorder. . In 2005, Cruise appeared in a sit-down interview with Matt Lauer to promote his film Civil War.

And the exchange between Lauer and Cruise took a turn for the worse after the topic of Shields and his Scientology teachings. 

As a member of the Church of Scientology, the actor is forbidden to take any kind of mind-altering substances, and to deal with the use of Shields, which is similar to his views on mental illness, Cruise said, I have not agreed with mental illness, absolutely. He prefers SSRI’s for good health.

Before I became a Scientologist I did not agree with that idea. And when I started studying the history of mental illness, I understood more about why I did not believe in the study of mental illness.

Types of homeostatic regulation

There are three main types of homeostatic regulation that occur in the body. Although their names may be unusual, you may encounter them every day.


When you think of homeostasis, the temperature may come to mind first. It is one of the most important and obvious homeostatic systems. Regulating body temperature is called thermoregulation.

All living things, from large mammals to tiny bacteria, must maintain a good temperature to survive. Other factors that influence this ability to maintain a stable body temperature include how these systems are regulated as well as the overall size of the organism.

Endotherms: some organisms, called endotherms or “warm-blooded” animals, do this through internal mechanisms. 

Ectotherms: some creatures are ectotherms (aka “cold-blooded”) and rely on the outside world to regulate their temperature. Reptiles and amphibians are both ectotherms.

The terms “warm-blooded” and “cold-blooded” do not mean that these organisms have different blood temperatures. These words simply refer to how these organisms maintain their internal body temperature.

Thermoregulation is also influenced by the size of the creature, or more specifically, the surface-to-volume ratio.

Large animals: large animals have very large bodies, which causes them to produce more body heat.


Small animals: small animals, on the other hand, produce less body heat but also have a higher volume-to-volume ratio. They lose more body heat than they produce, so their internal processes must work harder to maintain a stable body temperature. This is true even for babies, especially those born prematurely.


Osmoregulation attempts to maintain adequate water and electrolytes in and out of cells in the body. The balance of salt and water within the membrane plays an important role, as in osmosis, which explains the name “osmoregulation.” In this process, the kidneys are responsible for removing any excess water, waste, or electrolytes. Osmoregulation also affects blood pressure.

Chemical regulation

Your body organizes certain chemical reactions as well as maintenance systems in the center. These use hormones as chemical signalsfor example, blood sugar levels. 

In this situation, the pancreas would release insulin, when blood sugar levels are high, or glucagon, when blood sugar levels are low, to maintain homeostasis.

Impact of homeostasis

Homeostasis includes both physiological and behavioral responses. In terms of style, you can look for warm clothes or a sun patch if you start to feel cold. You can also curl your body in and keep your arms close to your body to keep in the heat.

As endotherms, humans also have several internal systems that help regulate body temperature. When your body temperature dips define several body processes respond to help restore balance. Blood vessels in the extremities are constricted to prevent heat loss. Shivering also helps the body generate more heat.

The body also responds when the temperature rises above normal. Have you ever noticed how red your skin gets when you get too hot? This is your body trying to restore the temperature. When you overheat, your blood vessels dilate to provide more body heat. Sweating is another common way to reduce body heat, which is why you often end up sweating on a very hot day.
