Playing devils advocate @Vertigo & @BAYLOR - as hindsight makes things soo easy - Harold had just utterly crushed the Norwegians (and a rebellious family member). He and his troops probably felt invincible. Perhaps he felt delaying and taking a rest might take the sheen off this feeling, allowing doubt to creep back in. And another factor - the less time they allowed the Normans in England the less deprivations against the Saxon population in the South. Harold was a seasoned fighting man, particularly on the Welsh border, who presumably acted from past experience and knew his strengths and weaknesses when it came to campaigns and battles with his men.
At the end of the day - like many battles - the result was actually on a knife edge. Harold, if he had held out that day, would have got stronger - as men were coming down from London, William weaker and presumably fighting a worsening morale - as practically all of the Normans 'plan A' frontal attack failed. It was probably in fact Harold's overly aggressive and confident elite troops (now a negative feature of the that morale Harold maybe tried to maintain?) that threw the battle by charging in piecemeal and getting destroyed bit by bit rather that sitting up the slope and being defensive.
oh...we're back to resting and perhaps giving the troops some time to get some 'fear' back
Mind you difficult thing being a king, no? This decision really had to be made instantly. It almost paid off.
