What are the dangers of hot tubs?

Andrew Huberman outlines several potential dangers associated with hot tubs, particularly concerning male reproductive health. Here are key points:

1. Sperm Health: Hot environments, such as hot tubs, can negatively impact sperm morphology and lead to dead sperm. This is due to the elevated temperatures, which are detrimental to sperm production and motility. The detrimental effects can last for up to 60 days, meaning that exposure today affects sperm produced in the next two months 1.

2. Reproductive Guidance: Andrew Huberman advises that men trying to conceive or maintain healthy sperm should avoid hot baths and hot tubs. Instead, he recommends using cold packs or ice water in saunas to mitigate the heat's impact on the testes 2.

For those trying to conceive, particularly, avoiding hot tubs and opting for cooler environments can help maintain optimal sperm health over time.
