Israeli Prime Minister Benjamin Netanyahu was released from the hospital with a heart monitor in his chest Sunday following a severe bout with dehydration this weekend, Israeli officials announced.

The Sheba Medical Center where Netanyahu was examined says the prime minister completed tests and is now in "excellent condition," adding that "his heart is operating well." The leader stayed in the medical center overnight after being rushed there on Saturday.

"Yesterday, I spent the day with my wife in the Sea of Galilee, in the sun, without a hat, with no water," a smiling Netanyahu shared from the hospital. "It's not a good idea."

The Prime Minister said that he had taken a holiday Friday with his family and temperatures were hitting 38 Celsius (100.4 Fahrenheit).
