Can accidentally swallowing ocean water while on the beach kill you Please answer immediately because my boyfriend did and he is feeling sick?

Swallowing ocean water generally poses a low risk of serious illness, but it can rarely cause health issues. Certain strains of bacteria in the ocean can lead to infections or more severe conditions in susceptible individuals with compromised immune systems.

If large quantities of water were swallowed quickly, it could lead to a disruption of the body's electrolyte balance, which in severe cases may result in nausea, confusion, seizures, and even unconsciousness.

Consult a healthcare provider as soon as possible if your boyfriend is experiencing symptoms such as intense vomiting, diarrhea, abdominal pain, fever, or dehydration. The symptoms may arise after hours or days, depending on the circumstances.
