Heat waves have an effect on both our physical and emotional wellbeing, according to studies.
High humidity and temperatures have been associated with an increase in the symptoms of bipolar illness, generalized anxiety disorder, and depression.
According to research, there is a 2.2% increase in mortality due to mental illness for every 1C increase in the monthly average temperature.
Heat waves have an effect on cognitive function as well, causing an increase in violent crime and aggressive behavior.
Acting on climate change is the best thing we can do for ourselves and future generations, according to scientists.
The effects of heat waves on our physical and emotional health are significant. They are typically dreaded by doctors because they cause emergency rooms to quickly become overcrowded with people who are dizzy, delirious, and fainting. Recent studies indicate that on days when temperatures hit or surpass the top 5% of the typical temperature range for a specific place, there is at least a 10% increase in hospital emergency room visits.
In people with mental health issues, extreme heat can exacerbate symptoms. Heatwaves, along with other weather-related catastrophes like floods and fires, have been associated with an increase in depressive symptoms in those who are depressed and an increase in anxiety symptoms in those who have a generalized anxiety disorder, a condition in which people feel anxious most of the time.
A connection exists between consistently high temperatures and both suicide and suicide attempts. And approximately speaking, the number of deaths connected to mental health rises by 2.2% for every 1°C increase in the monthly average temperature. Suicide rates are also greater when relative humidity fluctuates.
A spike in manic episodes in patients with bipolar disorder has been causally related to temperature and humidity changes brought on by human-induced climate change. The severity of the illness at this stage can lead to hospitalization for psychosis and suicidal ideation.
The fact that crucial medications used to treat psychiatric disorders may become less effective due to the effects of heat creates additional issues. We are aware that numerous medications raise the risk of heat-related mortality, such as antipsychotics, which can reduce thirst and cause people to become dehydrated. Some medications, like lithium, a very effective and popular mood stabilizer usually recommended for persons with bipolar disorder, will operate differently depending on the body temperature and how dehydrated the person is.
Fuzzy thinking, aggressive behavior.
Heat can also have an impact on a person's mental state, as well as their capacity for thought and reasoning. According to research, heat stress impairs the brain's ability to frame and solve complicated cognitive problems.
In a Boston University study, it was discovered that students who were housed in rooms without air conditioning during a heat wave performed 13% poorer on cognitive tests and had 13% slower reaction times than their counterparts.
People are more likely to grow frustrated and become aggressive when the heat impairs their ability to think rationally.
Strong evidence connects excessive heat to an increase in violent crime. A rise in the ambient temperature of even just one or two degrees celsius can result in a 3-5% increase in assaults.
Globally, it is predicted that by 2090, all types of crime may increase by up to 5% as a result of climate change. These increases are caused by a complicated interplay of psychological, social, and biological factors. For instance, high temperatures have an impact on the brain's chemical serotonin, which regulates aggression among other things.
On hot days, eco-anxiety can worsen as well. In a survey conducted in the UK, 60% of young people claimed they are either very concerned or extremely concerned about climate change. More than 45% of individuals surveyed claimed that their daily lives were impacted by their thoughts on the environment.
We still have a lot to learn about the intricate interactions and feedback loops between climate change and mental health, particularly those caused by heat waves. But we are aware that we are endangering both the world and ourselves in the game we are playing. Heat waves serve as essential reminders that combating climate change is the best thing we can do for both our own well-being and the well-being of future generations.
