Which outcome results in mammals when exposed to high environmental temperatures inhibiting sympathetic nervous activity in peripheral arterioles?

💡 Explanation

Enhanced evaporative heat loss occurs due to vasodilation increasing blood flow towards the skin surface, facilitating heat dissipation, because radiation of warmth is achieved and sweat glands are activated more readily. Therefore, heat loss arises, rather than shivering, which generates heat in this condition.
