After waking up from a three-day coma on Friday, actor Martin Lawrence remained in critical but stable condition, though doctors were still concerned about his kidneys.

Lawrence, 34, was jogging in the summer heat while wearing numerous layers of clothes. According to a hospital spokesperson, the actor, who jogs for at least an hour every day, fainted after intensifying his weight-loss regimen in preparation for an upcoming film role.

An hour later, his girlfriend found him slumped on the doorstep and dialed 911.

It was unclear whose film he was working on at the time, but he was recently cast in “See Spot Run,” in which he would portray a postal worker who adopts a particular dog.

Lawrence has appeared in several films, including Spike Lee’s 1989 big hit “Do the Right Thing” and Eddie Murphy’s “Life” this year. “Blue Streak,” his forthcoming film, is set to hit cinemas on September 17.

Lawrence had put on multiple layers of clothes in a bid to “sweat off” the pounds and suffered heat stroke as a result. Lawrence arrived to the Los Robles Medical Center in Thousand Oaks, Calif., with a body temperature of 107 degrees.

“He’s definitely not out of the woods by any means, but this was a man who was near death who has made a miraculous comeback,” Los Robles Regional Medical Center spokesperson Kris Carraway-Bowman said.

“He was doing what he saw fighters do. He put on several layers of heavy clothing and was jogging in the intense heat we had here Sunday, and collapsed in front of his home,” said Kris.

The former star of the Martin comedy was attentive, his eyes were focused, and he was able to obey physicians’ orders. But he was still on a ventilator.

According to Carraway-Bowman, Lawrence now responds to instructions like “squeeze my hand.”

Lawrence’s health, she stated, had barely marginally improved. His prognosis is uncertain, and he is experiencing renal problems. “He’s not able to respond to you if you ask him a question. He’s basically sleeping,” she said.

“When you come in with a temperature of 107, that’s not very compatible with life,” said critical care nurse Susie Faz. “He’s a very lucky man.”

He got stuck in traffic on bustling Ventura Boulevard in May 1996 and started ranting. Police took him away after discovering a loaded weapon in his pocket, and he was taken to Cedar-Sinai Hospital, where he was diagnosed with tiredness and dehydration.

Lawrence had a seizure after failing to take recommended medicine, according to his doctor.

He was detained at Burbank Airport two months later when police discovered a loaded weapon in a luggage he was carrying on a flight to Phoenix.

He was sentenced to two years probation and community service in September 1997 for his role in a nightclub brawl. The actor was also sentenced to a treatment program after pleading no contest to battery.

Martin first aired on Fox in 1992 and was cancelled in November 1996. Life, Bad Boys, and Nothing to Lose are among his cinematic credits.
