Scientists say that between 3 AM and 4 AM, the human body reaches its lowest point in a 24-hour cycle. This is when guards, lookouts, and sentries are most likely to fall asleep.

To counter this, old-time seafaring vessels developed a special form of timekeeping: a ship’s bell would ring every half hour, increasing in number until it reached “eight bells,” helping to keep night watchmen alert.

Captains also used a “dog watch,” a shortened shift designed to bring fresh sailors on deck and prevent fatigue from setting in.

It’s a good thing 19th-century adventurers didn’t have a “Capybara watch,” because this bleary-eyed bara looks about ready to fall asleep in the middle of the afternoon!

Thanks for reading and have a great Sunday!
