The answer to 'why is my spider health risk' is that spiders generally pose little health risk to humans. Most spider species are not aggressive and their venom is not potent enough to cause serious harm. However, some spider bites can cause mild symptoms like swelling, redness, and pain.
The main health risk from spiders is the potential for allergic reactions or bites from a few venomous species, such as the black widow or brown recluse spiders. These bites can cause more severe symptoms like muscle pain, nausea, or difficulty breathing. But serious injuries or deaths from spider bites are extremely rare.
