It was due to the fatal dase of radiation he'd received.
As noted, the Doctor frequently experiences a period of physical and mental instability following regeneration and some post-regeneration experiences have been more difficult than others. Notably, the Fifth Doctor (in Castrovalva) begins reverting to his previous personalities and the Sixth Doctor experiences extreme paranoia, flying into a murderous rage and nearly killing his companion (The Twin Dilemma, 1984). The Eighth Doctor experienced amnesia as a result of post-regeneration trauma (the 1996 television movie); uniquely, the Doctor was 'not alive' at the time of this regeneration. The regeneration from the Ninth to the Tenth Doctor sees the Doctor unconscious for most of the next fifteen hours ("The Christmas Invasion"). The experience is also traumatic enough to cause one of his hearts to stop beating temporarily. The regeneration of the Tenth Doctor to the Eleventh Doctor was particularly violent, causing severe damage to the interior of his TARDIS, shattering the windows, setting the console room on fire, and causing the TARDIS to plummet towards Earth (The End of Time).
Because the doctor, when he was dying of radiation, had the radiation in him and when he regenerated, he was on fire and the fire exploded in the tardis and it got ruined so they changed the destroyed interior to a new and, probably, better one.
Fire plays a crucial role in the regeneration of a savannah ecosystem. It helps control the growth of trees, stimulates seed germination, and provides nutrients for new plant growth. Fire also helps maintain the diversity and structure of the savannah landscape.
After a fire in the pine barrens, new growth and regeneration of the ecosystem typically occur. The fire can promote the release of seeds and stimulate the growth of certain plant species that are adapted to fire, leading to a rejuvenation of the landscape.

Can an employer fire you even with doctors excuses?

First it depends on what state you live in. An organization can not legally fire you if you have a doctors note; however a lot of employers do this.
In folklore, fire symbolizes purification and renewal, making it an effective weapon against supernatural creatures like vampires which are often associated with evil and darkness. Fire is also believed to destroy a vampire's physical body to ashes, preventing regeneration. This vulnerability to fire adds to the mystique and danger surrounding vampires in popular culture.

In ecology, the regeneration scheme refers to the process by which a habitat or ecosystem is naturally restored or replenished through the growth of new plant life after a disturbance like a forest fire or logging. This process helps to maintain biodiversity and ecosystem functions over time. Different species play different roles in the regeneration scheme, with some being pioneer species that quickly colonize disturbed areas and others being late-successional species that take longer to establish.
It is not guaranteed that moss will be the first vegetation to grow back after a forest fire. The regeneration process depends on a variety of factors including the severity of the fire, the presence of surviving plant species and seeds, and environmental conditions. Mosses typically thrive in moist and shady environments, so their growth may be influenced by the availability of these conditions post-fire.
