When you’re dehydrated, you have less water in your blood so the blood becomes more concentrated and blood volume decreases. Your kidney is used to filtering all the blood, so it can feel when you have less blood to filter, and it releases hormones that help increase your blood pressure and decrease the amount of water in your pee. A special part of your brain samples your blood and can sense both the kidney hormones and the increased blood concentration. This brain part sends signals to the area responsible for thirst, turning the thirsty feeling on.

The body has specialized cells (called "osmoreceptors") in certain areas that measure the osmolality of blood. (An example is the organum vasculosum of the lamina terminalis, or OVLT, if you're curious). Losing water increases blood osmolality (usually around 290 mOsm/L), which is sensed by the osmoreceptors. The osmoreceptors in turn activate two mechanisms:

  1. They activate the thirst center (in the hypothelamus)
  2. They cause the secretion of vasopressin (antidiuretic hormone / ADH) from the pituitary gland, which increases the retention of free water (ie water without solutes) in the kidneys

These mechanisms increase the free water concentration of blood, causing blood osmolality to return to normal.

Please note that different mechanisms exist to address a decrease in blood volume, and if both blood volume decreases and osmolality increases, both categories of mechanisms will activate. There's considerable overlap between these mechanisms.

The sensation of feeling thirsty is caused by a variety of factors, but one of the main causes is dehydration. When our bodies lose fluids, such as through sweating, urination, or vomiting, we can become dehydrated. As the level of fluids in our bodies decreases, our bodies send signals to our brains to let us know that we need to replenish the fluids.

One of the main ways that our bodies send these signals is through a hormone called vasopressin, also known as antidiuretic hormone (ADH). When our bodies are dehydrated, the level of ADH in our bodies increases. This hormone helps to regulate the amount of water in our bodies by signaling to our kidneys to conserve water and reduce the amount of urine produced. As a result, we may feel thirsty as our bodies try to conserve water and maintain proper fluid balance.

In addition to the release of ADH, other factors that can contribute to feeling thirsty include an increase in body temperature, an increase in the concentration of electrolytes in our bodies, and certain medications or medical conditions.

Seriously. Terrible answer and very clearly from ChatGPT or the like.

When I get bored I go trawling for AI comments. This sub is heavily infected.

How would you know? And why would there be AI?

Determining whether a comment is generated by an AI can be difficult. AI generated text has become more and more realistic with the advance of new technologies.

One way to identify an AI generated comment is to notice the structure of AI generated comments. They will typically restate the question or provide an introductory paragraph before going on to present statements in a high school essay format.

Another way to identify AI generated comments is to check the comment history of the person posting the comment. Profiles that post AI generated comments will comment on multiple posts in subreddits which ask and answer questions, often on very diverse topics. You might also notice a sudden change in the syntax of their comments over time.

In conclusion, look for comments that have a clear beginning and middle, and that end with a conclusion.

Or just be me, and recognise the shitty text on sight.

There are several ways to identify AI-generated comments on Reddit or any other platform. Here are a few methods you can use:

Check the language: AI-generated comments often have unusual or repetitive language patterns. They may also use words or phrases that do not make sense in the context of the discussion.

Look for patterns: AI-generated comments may be posted in large numbers and follow a similar pattern or structure.

Check the account: AI-generated comments are often posted from newly created or suspicious-looking accounts.

Use a tool: There are tools available that can analyze the content of a comment and determine if it was generated by an AI or a human. One example is the GPT Detector, which is a tool developed by OpenAI that can detect AI-generated text.

It's important to note that it can be difficult to accurately identify AI-generated comments, as the technology is constantly improving and evolving. It's also possible for humans to mimic the language patterns of AI-generated text, so it's always best to use multiple methods to verify the authenticity of a comment.

As for WHY?

There are several reasons why someone might post AI-generated comments on Reddit or any other platform. Some possible motivations include:

Spamming: AI-generated comments can be used to spam forums or other online communities with irrelevant or off-topic content.

Disinformation: AI-generated comments can be used to spread false or misleading information in an attempt to manipulate public opinion or disrupt discussions.

Advertising: AI-generated comments can be used to promote products or services in an attempt to drive traffic or sales.

Mischief: Some people may post AI-generated comments simply to cause confusion or disrupt conversations for the sake of it.

It's important to be aware of the potential for AI-generated comments and to be cautious about the content you encounter online. Always verify the authenticity of a comment before taking it at face value, and report any suspicious activity to the platform or community moderation team

Thank you very much!

I still don't understand why would bother creating a bot for a sub reddit like eli5

No problem pal.

The joke here was that my post was entirely created by AI... Chat GPT :)
