If you have stepped outside lately, you already know the heat is not smiling at anybody. One minute you are going about your day, the next you are looking for shade, fanning yourself or reaching for cold water.

Across Nigeria, hot weather affects everyday life in different ways. A trader spending hours at the market, a farmer working under the sun, a student walking to school or a driver navigating a long journey may all experience the heat differently. What they have in common is the need to protect themselves from excessive heat and replace the fluids their bodies lose.

And that is where hydration comes in.

The heat is more than just uncomfortable

Nigeria does not experience the same temperatures everywhere, and the weather can vary significantly from one region to another. However, high temperatures can become a health concern wherever they occur.

As Nigeria moves towards the dry season, temperatures and heat discomfort can increase in some areas. The Nigerian Meteorological Agency (NiMet) monitors weather conditions and issues forecasts and advisories to help people prepare.

When the weather is hot, your body sweats to regulate its temperature. The more you sweat, particularly during physical activity or prolonged exposure to the sun, the more water you may lose.

If you do not replace enough of that fluid, dehydration can develop. You may experience a headache, dizziness, dry mouth, unusual tiredness or darker-than-usual urine. These symptoms can have other causes, but they should not be ignored, especially after spending time in the heat.

According to the World Health Organisation, extreme heat can cause dehydration, heat exhaustion and potentially life-threatening heatstroke.

Do not wait until you are desperately thirsty

Think about how many times you have left home in the morning, got caught up with work, school, business or other activities, and suddenly realised you have barely had any water all day.

It happens easily. When there is so much to do, drinking water can become an afterthought.

But staying hydrated should be part of your daily routine, especially during hot weather. Drink water regularly throughout the day and pay extra attention when you are sweating heavily or spending long hours outdoors.

You do not need expensive beverages or complicated routines to get started. Safe drinking water is one of the simplest ways to help your body replace lost fluids.

Simple ways to stay hydrated in the heat

Whether you are travelling between states, heading to work, attending lectures or spending the day at the market, keep drinking water within reach. It is easier to drink regularly when water is available. If your work or daily activities keep you outdoors, rest in shaded or cooler areas whenever possible. Where you have flexibility, avoid strenuous activities during the hottest part of the day.

Add water-rich foods to your meals. Watermelon, oranges, cucumbers and other fruits and vegetables can contribute to your daily fluid intake. Enjoy them alongside regular drinking water.

Dressing for the weather is also important. Lightweight, loose-fitting clothing can help your body manage heat more comfortably. A hat or umbrella can also provide some protection from direct sunlight.

If you feel dizzy, unusually weak or nauseated after being in the heat, move to a cooler place and rest. Drink water if you are fully alert and able to swallow. Seek medical attention if symptoms are severe or persistent.

Confusion, fainting, seizures or loss of consciousness can signal a medical emergency. Seek urgent help and begin cooling the affected person while assistance is on the way. Never force fluids into someone who is confused or unconscious.

Children, older adults, outdoor workers and people with certain health conditions may need particular protection during periods of extreme heat.

Staying hydrated matters more than ever

The weather may be beyond our control, but the steps we take to protect ourselves still matter.

Whether you are in Kano, Abuja, Ibadan, Port Harcourt, Maiduguri or a smaller community, the message remains the same: pay attention to the heat, drink water regularly and give your body time to cool down.

Remember, though, that drinking water alone cannot prevent every heat-related illness. Staying in cooler places, limiting exposure to extreme heat and recognising danger signs are equally important.

The sun will rise tomorrow, and there will still be work to do. So, before you step out, take your water with you. Your body has enough to deal with without dehydration joining the list.
