Why do guys shake after peeing?

The shivering some men experience after urinating is likely due to a sudden drop in blood pressure.

Understanding Post-Pee Shivers in Men

Many people have wondered why men sometimes shake or shiver after urinating. While it's a common occurrence, it's not fully understood. However, some experts have explanations based on physiology. Here's a detailed breakdown:

Blood Pressure Changes

  • Standing and Urination: According to experts, one key factor could be the fact that men often stand while urinating. This position can cause blood pressure to drop rapidly. When blood pressure drops suddenly, the body can react by shivering to try and regulate temperature and pressure.
  • Blood Pressure Increase with Standing: The opposite can occur as well, with blood pressure increasing when a person stands. The act of urinating can then be a factor in creating a shift in the body.

Other Possible Factors

While the drop in blood pressure is a strong potential cause, there are other possible explanations:

  • Nerve Signals: The act of releasing urine can trigger nerve signals that might result in a shiver.
  • Temperature Regulation: Some research suggests that urination could be associated with a change in the body's internal temperature regulation, which can sometimes cause a shiver.

Summary of Factors

Factor Explanation
Blood Pressure Drop Standing while urinating can cause a rapid drop in blood pressure, triggering the body to shiver.
Nerve Signals The act of urination might cause nerve signals that induce shivering.
Temperature Regulation Changes in the body's internal temperature related to urination could trigger shivers.

Conclusion

While the exact reason for post-pee shivers in men may vary for individuals, the most widely accepted explanation involves sudden shifts in blood pressure that can occur when standing to urinate. This is coupled with potential signals sent by nerves related to urination, which could influence the shivering reaction.
