The increasing global temperatures are not only a physical health threat but also pose significant challenges to mental well-being.

Global Heat Wave

A heat wave occurs when temperatures reach at least 40 degrees Celsius in plains or 30 degrees Celsius in hilly areas. This extreme heat can lead to various health issues, including mental health challenges. The harsh sun rays and high temperatures can cause people to feel dehydrated and sweaty, but beyond these physical effects, extreme heat can also influence mental states. It can disrupt mood, sleep, and even exacerbate existing mental health conditions.

List of Effects on Mental Health

Mood Swings

High temperatures have been linked to increased irritability, anxiety, and depression. People may experience more mood swings and aggression during heat waves.

Difficulty in Focusing

Concentration and clear thinking can be hampered by extreme heat. Completing tasks that are usually easy can become challenging due to the impact of high temperatures on cognitive function.

Disrupted Sleep Patterns

Heat, especially at night, can disturb sleep. Poor sleep quality can result in fatigue, grumpiness, and a worsening of mental health conditions like anxiety and depression.

Feeling Stressed or Overwhelmed

Extreme heat can leave people feeling unusually stressed or overwhelmed. Concerns about dealing with the high temperatures and their effects on daily life can amplify stress levels.

Behavioral Changes

Behavioral changes, such as increased impulsivity and difficulty controlling anger, are common during heat waves. People may act differently than usual due to the stress of the high temperatures.

Worsening of Existing Mental Health Conditions

Higher temperatures can aggravate pre-existing psychiatric conditions, such as substance abuse, anxiety, and schizophrenia. Those with these conditions may find their symptoms worsening during heat waves.
