Understanding Heatwaves: What You Need to Know
What Exactly is a Heatwave?
A heatwave is a prolonged period of excessively hot weather that can be dangerous for your health and well-being. The IMD defines a heatwave in India as when the maximum temperature of a region reaches 40°C or more in the plains, 30°C in the hills, and 37°C along coastal areas.
But heatwaves aren’t just about high temperatures—they also involve a noticeable difference from normal temperatures. For example, a heatwave is only classified when the temperature exceeds typical values by at least 4.5°C to 6.4°C. A severe heatwave is when this deviation surpasses 6.4°C. In such conditions, people are more likely to experience heat-related illnesses like dehydration, heat exhaustion, and even heatstroke.
Why is This Year’s Heatwave More Intense?
According to the IMD, this year’s forecast is particularly worrying due to the expected increase in heatwave days. For many regions, this means longer stretches of extreme heat, which could last up to 10-11 days. Compared to the usual 4-7 days, this is a significant jump, meaning the risk of health complications from heat-related issues is higher than before.
While heatwaves are a regular occurrence in India during the summer months, the combination of longer durations and higher-than-usual temperatures this year is raising alarms. This pattern is likely influenced by global climate change, which is causing more frequent and intense weather events like these.
Affected Regions and How They’re Preparing
According to the IMD, 17 states are at high risk of heatwaves this April. These include Rajasthan, Gujarat, Madhya Pradesh, Haryana, Uttar Pradesh, Maharashtra, and several others. In these states, residents will likely experience the hottest temperatures of the year, with some areas reaching 105°F (40°C) and beyond.
These regions are already preparing for the intense heat, with local governments setting up cooling centers, issuing heat advisories, and implementing measures to help people stay safe. Urban planning also plays a role, with initiatives focusing on increasing green spaces and improving water supply systems to combat the heat island effect in cities.
Practical Steps to Stay Safe During a Heatwave
As temperatures soar, it’s crucial to take proactive measures to protect yourself and your family. Here are some practical steps to stay safe during a heatwave:
1. Stay Hydrated
Dehydration is one of the most common and dangerous effects of extreme heat. When you sweat, your body loses water and essential minerals, so it’s important to drink plenty of water throughout the day. Avoid drinks with caffeine or alcohol, as they can dehydrate you. Keep a water bottle with you at all times, especially if you need to be outside.
2. Limit Outdoor Exposure
During a heatwave, it’s best to avoid spending extended periods of time outside, especially during the hottest parts of the day—typically between 10 a.m. and 4 p.m. If you must go outside, wear light-colored, loose-fitting clothing to help your body stay cool. Sunscreen is also essential to prevent sunburn and skin damage.
3. Stay Cool Indoors
If possible, stay indoors in air-conditioned or well-ventilated spaces. Close curtains or blinds during the day to keep the heat out and open windows during the evening when it’s cooler. If air conditioning isn’t available, using fans and cool, damp cloths can help bring your body temperature down.
4. Recognize Heatstroke and Heat Exhaustion
Heatstroke is a medical emergency that can be life-threatening. It occurs when your body temperature reaches dangerously high levels (above 104°F / 40°C). Early signs of heat exhaustion, such as heavy sweating, nausea, headaches, and dizziness, should never be ignored.
If you or someone else experiences symptoms of heatstroke or heat exhaustion, move them to a cooler place, hydrate, and seek medical help immediately.
5. Prepare Your Home and Workplace
Businesses and homeowners alike should be prepared for heatwaves. This can involve ensuring access to cool water, setting up air conditioning or fans, and educating employees or family members about the dangers of excessive heat.
Local governments and businesses should also collaborate to ensure that cooling centers are available for vulnerable populations, such as the elderly, children, and people with medical conditions.
Urban Heat Island Effect: A Growing Concern
The urban heat island effect is a phenomenon where urban areas become significantly hotter than surrounding rural areas due to human activities and infrastructure. Cities are particularly vulnerable to heatwaves because of asphalt roads, concrete buildings, and the lack of sufficient green spaces, which absorb and retain heat.
To mitigate this effect, cities must invest in more greenery, such as green roofs, public parks, and tree-lined streets. These efforts can help lower local temperatures, reduce energy consumption, and create a more livable environment during extreme heat events.
In addition to urban planning, it is also essential for individuals to reduce energy consumption by using energy-efficient cooling systems and switching off unnecessary appliances to avoid additional strain on the power grid.
Cooling Centers and Community Support
In anticipation of the heatwave, local governments have set up cooling centers across high-risk areas. These centers are designed to offer relief to individuals who are most vulnerable to heat, such as the elderly, children, and those with pre-existing health conditions. Community organizations are also stepping in to provide free water and shade for people who cannot access air-conditioned spaces.
If you’re aware of a cooling center or community-based initiative in your area, make use of it. These resources can make a significant difference in staying safe during intense heat events.
