If you've been feeling more on edge recently, you're not the only one. People often seem more aggressive during periods of intense heat.

As it turns out, there's scientific evidence to back that claim. In fact, it turns out that it's not your fault: many studies have concluded that hot weather does, in fact, make people more aggressive.

This may help explain in part why there has been a streak of violent crime in the city. For example, 3 people were victims of stabbings on Sunday night in Montreal, two of whom later died of their injuries.

Psychology Today has summarised the findings of studies which explore the link between heat and violent outbursts.

Most studies agree that there is a link between heat and violent outbursts, but they disagree on how, exactly, the weather affects these outbursts.

Field studies, for example, "confirmed that violent crime increases with temperature but that nonviolent crime does not."

Lab studies, on the other hand, show an "inverted U-shaped relationship in which aggression increases with temperature up to a certain point," which is around the low 30°C range.

However, aggression falls again when the temperature surpasses this heat threshold.

According to the Journal de Montréal, this aggression is in part due to our body's reaction to the heat.

When it is warm, our heart beats faster per minute, we use more testosterone, and we are quicker to anger.

So, just remember to take a deep breath before yelling at some poor fast-food worker because they messed up your order. It's not you, it's the weather.
