Nepal Issues Heatwave Alert as Rising Temperatures Put Lives at Risk

Nepal’s Ministry of Health and Population is urging people to take heat precautions as rising temperatures increase the risk of loo and other heat-related illnesses across several parts of the country.

Assistant Spokesperson Dr. Samir Kumar Adhikari said the danger is growing alongside global temperature increases, with the Terai region facing the highest risk. Officials are advising residents to drink plenty of water, avoid unnecessary outdoor activity, and stay away from direct sun during the hottest hours of the day.

Why the warning matters

Extreme heat is not just an inconvenience in Nepal. Research and policy briefs on the country’s heat risk describe it as a growing public health threat, especially in the Terai where temperatures can climb sharply during heatwaves and prolonged dry spells.

Reports on Nepal’s heat crisis note that repeated exposure to extreme temperatures can contribute to heat exhaustion, dehydration, and more severe conditions such as heatstroke, which can be fatal if not treated quickly.

What is 'loo'?

Loo is the hot, dry wind that can make already high temperatures feel even more punishing. In South Asia, it is often associated with heat stress, dehydration, and a higher risk of illness among children, older adults, outdoor workers, and people with existing health conditions.

As temperatures rise, this kind of weather becomes more dangerous because the body struggles to cool itself effectively, especially when humidity is high or drinking water is limited.

Who is most at risk?

Public health experts have repeatedly identified the most vulnerable groups during heatwaves as outdoor workers, older adults, children, pregnant people, and those living in areas with limited shade, water, or cooling options.

Studies on heat exposure in Nepal also highlight risks for people who spend long hours outside, since prolonged exposure can lead to fatigue, headaches, fainting, and more serious heat-related emergencies.

How to stay safe during extreme heat

Health officials and heat-response experts recommend a few basic steps to reduce the risk of heat illness:

Stay hydrated throughout the day, even if you do not feel thirsty.

Avoid outdoor exposure during peak heat hours, especially in the afternoon.

Seek shade or cooler spaces whenever possible.

Wear light, breathable clothing and cover your head if you must go outside.

Watch for warning signs such as dizziness, nausea, severe headache, confusion, or rapid heartbeat.

If someone shows signs of heatstroke, medical help should be sought immediately because it is a life-threatening emergency.

A growing climate challenge

Nepal’s heat problem is increasingly being linked to broader climate change trends, with policy groups calling for better early warning systems, localized heat action plans, and stronger community-level preparedness.

Some cities in Nepal have already begun testing heat response measures, including public alerts, access to drinking water, and awareness campaigns. Those efforts point to a bigger reality: heat is becoming a serious and recurring risk that now requires the same level of planning as floods, landslides, and other climate hazards.

For now, officials say the immediate message is simple: drink water, stay cool, and limit exposure while temperatures remain dangerously high.
