As temperatures continue to soar across many parts of India, stepping outside during peak heat hours can become more than just uncomfortable, it can pose serious health risks. Extreme heat can affect the body's ability to cool itself, increasing the chances of dehydration, heat exhaustion, and even heat stroke, a potentially life-threatening condition. Knowing when it is unsafe to go outdoors and how to protect yourself during a heatwave is essential, especially for children, older adults, and people with existing health conditions.

The most important advice is to stay indoors if the temperature outside is higher than 40°C. This is especially important if the air is dry and there is little breeze. Staying indoors helps to protect against heat-related illnesses, such as heat stroke, since the body is not able to cool itself as effectively in dry, hot conditions [1][2].

Additionally, when the temperature is that high, even a small amount of activity can be exhausting and draining for the body.

If you must go out, try to avoid the hottest part of the day, usually mid-day when the sun is at its highest. Wear light, loose-fitting clothing and ensure you have a hat and sunglasses to protect you from the sun. Also, drink plenty of fluids to avoid dehydration [3].

When Should You Not Leave the House During A Heatwave?

As per government guidelines, if you have to go outside, stay in the shade, particularly between 11 am and 3 pm - and if possible, avoid going outside during this time [4].

If you have any underlying medical conditions, you should be particularly careful when the temperature outside is high. It is wise to seek medical advice if you are feeling unwell and have symptoms such as dizziness or confusion.

Heatwave In India: Who Are At Risk?

It is also important to be aware of the risks that heat waves pose to young children and the elderly. Young children may not be able to regulate their body temperatures as well as adults, so they need to be monitored carefully in hot weather [5].

The elderly are also more at risk of heat-related illnesses, so it is important to check in on elderly neighbours and relatives regularly when it is hot outside. This is because the elderly often have weaker immune systems, making them more susceptible to heat-related illnesses such as heat exhaustion and heat stroke [6].

Bottomline

In short, heat waves can be dangerous, so it is important to stay indoors when the temperature is above 40°C and be careful if you must go out. Be aware of the risks to children and the elderly and seek medical advice if you feel unwell.
