How does hot weather affect your emotions?
Have you ever felt uncomfortable and easily angered during days of stuffy hot weather? Don't worry, you're not alone! Many scientific studies have proven the connection between hot weather and negative emotions in humans.
This article will help you understand the causes and learn how to effectively control your emotions during extremely hot days.
Hot summer days don't just affect our bodies but also have a strong impact on our mental state.
Heat Outside, Anger Inside
Vietnamese summer, especially in major cities like Hanoi or Ho Chi Minh City, regularly sees temperatures exceeding 35-40°C. In that suffocating environment, many people become irritable, impatient, and easily angered by trivial matters.
The phenomenon of heat making mood worse has been experienced by many but few understand the scientific reasons behind it.
Traffic jams under the hot sun are one of the factors that make many people feel annoyed and uncomfortable.
Common situations for Vietnamese people during hot weather
- Getting frustrated when stuck in traffic under intense heat
- Snapping at colleagues over minor issues
- Losing patience when waiting in lines
- Having difficulty concentrating in hot offices
But does hot weather really affect our mood and behavior, or is it just a subjective feeling? Science has given a clear answer: Yes, high temperatures directly impact emotions and our ability to control them.
Scientific Explanation: Why Hot Weather Makes Us Irritable?
1. The Body's Response to High Temperatures
When environmental temperature rises, our bodies work hard to maintain stable body temperature. This causes many physiological reactions leading to prolonged stress due to hot weather.
High temperatures activate the sympathetic nervous system, increasing stress levels and reducing emotional control ability.
Sympathetic nervous system activation
- Increased heart rate and blood pressure
- Feelings of tension and fatigue
- Reduced tolerance to external stimuli
Decreased serotonin in the brain
- Serotonin is a neurotransmitter related to happiness and calmness
- High temperatures reduce serotonin levels
- Result: easier to fall into negative states and difficult to maintain stable mood
2. Dehydration and Disrupted Sleep During Hot Weather
In hot weather, the body sweats more, leading to rapid dehydration and causing many problems. The link between hot weather and negative emotions becomes clearer when the body becomes dehydrated.
Rapid body dehydration in hot weather causes the brain to function less effectively and affects emotions.
Effects of dehydration
- Reduced ability to concentrate
- Increased feelings of fatigue
- Less efficient brain function
- Decreased emotional control ability
Additionally, high nighttime temperatures cause sleep difficulties, disrupting natural sleep cycles. According to research from Verywell Mind, just 1-2 hours of sleep deprivation each night is enough to significantly increase the risk of irritability and conflict in relationships.
3. Increased Risk of Negative Behavior
Hot weather affects not only individual mood but also has connections to broader social issues. The phenomenon of heat making mood worse doesn't just impact individuals but also affects collective behavior.
Statistics show that rates of social conflict and psychological problems typically increase during prolonged heat waves.
Notable statistics
- Crime rates increase during hot days
- Street conflicts occur more frequently
- Domestic violence tends to rise with high temperatures
Impact on mental health
- Worsens symptoms of anxiety and depression
- Creates a vicious cycle: hot weather → increased stress → reduced emotional control ability
Ways to Control Emotions in Hot Weather
Understanding how high temperatures affect emotions, we can apply many effective measures to maintain calmness and positivity. Controlling emotions when it's hot becomes a necessary skill for summer.
1. Adjusting Your Living Environment
The simplest measure is to keep your living and working space as cool as possible.
Creating a cool living space with light colors and plants significantly reduces the negative effects of high temperatures.
Specific solutions:
- Use air conditioning, fans, sun-blocking curtains
- Limit going outside during peak heat hours (10AM-4PM)
- Decorate interiors with cool color schemes (green, blue, light purple)
- Place indoor plants to increase humidity and create a comfortable feeling
A cool environment not only helps your body function more effectively but also positively affects your mood, helping you maintain emotional control even when hot weather outside intensifies.
2. Taking Care of Your Body
Drinking enough water is the most important factor for controlling emotions in hot weather. Adequate hydration helps effectively reduce stress due to hot weather.
Drinking enough water and cool herbal teas is a simple but effective measure to maintain stable emotions.
Expert advice:
- Drink at least 2-2.5 liters of water daily
- Can increase to 3 liters on especially hot days
- Limit alcoholic and caffeinated beverages
- Prioritize cool herbal teas (chamomile, mint, artichoke...)
Proper diet:
- Prioritize light, easily digestible, and water-rich foods
- Increase green vegetables and fruits
- Reduce spicy, hot, and greasy foods
- Supplement essential vitamins and minerals (especially magnesium and B vitamins)
When the body is properly cared for, the brain also functions more effectively, helping you maintain a positive mood and better control your emotions.
3. Managing Emotions During Hot Weather
Practicing relaxation techniques can help you reduce stress and maintain calmness even when temperatures rise. The following methods for controlling emotions when it's hot have proven effective.
