When you mention people getting "angry when they are in heat," it's essential to clarify the context. If you are referring to heat as in high temperatures or hot weather, there are a few reasons why some individuals may experience increased irritability or anger:
Physical discomfort: High temperatures can cause physical discomfort, such as sweating, dehydration, and heat exhaustion. When people are uncomfortable, their patience may wear thin, leading to increased irritability and a shorter temper.
Sleep disturbances: Hot weather can disrupt sleep patterns, leading to sleep deprivation and fatigue. Lack of proper rest can make people more susceptible to irritability and mood swings.
Dehydration: In hot weather, the body loses more fluids through sweating, and if people don't adequately hydrate, it can lead to dehydration. Dehydration can affect cognitive function and mood, making people more prone to irritability and anger.
Environmental stress: Hot weather can exacerbate other environmental stressors, such as increased noise levels, crowded spaces, or discomfort in public transportation, which can contribute to heightened emotions.
On the other hand, if you are referring to "in heat" as a phrase used to describe animals' mating season, it typically applies to non-human animals, particularly mammals like dogs and cats. During their reproductive cycle, animals experience hormonal changes, which can influence their behavior, including increased aggression or irritability as they seek mates or establish dominance.
It is essential to understand that human behavior is influenced by a combination of physiological, psychological, and environmental factors. While some individuals may become angrier or more irritable during hot weather, it is not a universal response, and different people may react differently to heat and other environmental conditions.
