Spending time outside is wonderful, especially when the sun is shining. But when the weather gets really hot, people need to be careful. Doing things outdoors, whether for fun, exercise, or work, can become risky if individuals are not prepared for the heat. The body works hard to stay cool, but hot weather can put a lot of stress on it, sometimes leading to problems like feeling tired, dizzy, or even getting seriously sick from the heat.
The good news is, with a little planning, people can still enjoy or complete their outdoor tasks safely. It’s all about understanding how the heat affects the body and taking smart steps to provide protection.

Understanding How Heat Affects the Body
When it’s hot, the body tries to cool itself down mostly by sweating. As sweat dries on the skin, it takes some heat with it, helping one feel cooler. But if it’s too hot, too humid, or someone is working too hard, their body might not be able to cool itself enough. Body temperature can rise, putting a strain on the heart and other organs. This can quickly lead to feeling unwell, so knowing how to avoid this is key.
Tip 1: Think About the Time of Day
The sun is usually strongest and the air is hottest during the middle of the day, typically between 10 in the morning and 4 in the afternoon. This is the time when heat stress is most likely to happen.
- Go Early or Go Late: The smartest plan is to do outdoor activities either in the early morning (before 10 AM) or later in the evening (after 4 PM or even after sunset). The air will be cooler, and the sun’s rays will not be as direct.
- Check the Forecast: It’s always wise to take a quick look at the weather forecast before going outside. Paying attention to how hot it will be and also how humid it feels is important, as humidity can make the heat feel much worse.
Tip 2: Choose Clothes Wisely
What one wears plays a big part in how well the body can cool down.
- Light Colors and Loose Fit: People should pick clothes in light colors (like white, light blue, or yellow). Dark colors absorb more heat from the sun. Clothes should be loose, not tight. Loose clothing allows air to move around the body, helping sweat dry and cool someone down.
- Light Materials: Choosing fabrics that are lightweight and can help sweat move away from the skin is helpful. Cotton is a good choice for many. Some sports clothes are made with special materials that “wick” sweat away, which can also be helpful.
- Cover Up: Wearing a wide-brimmed hat can shield the face, ears, and neck from the sun. Sunglasses protect the eyes. Even wearing long sleeves and long pants made of light, breathable fabric can help protect the skin from direct sun and prevent sunburn, which makes it harder for the body to cool itself.
Tip 3: Drink Plenty of Water
Staying hydrated is probably the most important thing an individual can do when it’s hot. The body uses water to sweat, so that water needs to be put back in.
- Drink Before Thirst: One should not wait until they feel thirsty. Thirst is a sign that the body is already starting to lose too much water. Drinking water regularly, even if one doesn’t feel like it, is advised.
- Before, During, and After: Start drinking water before even going outside. Continue sipping water often while active, and make sure to drink more once the activity is done.
- What to Drink: Plain water is usually the best choice for most activities. If someone is doing something very active for a long time (more than an hour), a sports drink can help replace salts and minerals the body loses when sweating a lot. It’s generally better to stay away from sugary drinks, coffee, and alcohol, as they can actually make the body lose more water.
Tip 4: Listen to the Body and Pace Activities
It’s easy to get caught up in an activity, but the body will send signals if it’s getting too hot.
- Start Slow: If an individual is not used to being active in the heat, they should begin with shorter activities and go at a slower pace. Gradually, over several days, the body can get more used to the heat.
- Take Breaks: Planning to take breaks often, especially in shady or cool spots, is important. If someone is working, their supervisor should help plan these breaks.
- Know the Signs: People should pay attention to how they feel. If one starts to feel very tired, dizzy, lightheaded, gets a headache, feels sick to their stomach, or has muscle cramps, these are signs that they need to stop.
Tip 5: Protect Skin from the Sun
Sunburn not only feels bad but also makes it harder for the body to cool down.
- Sunscreen: Using sunscreen on any skin that isn’t covered by clothing is important. People should choose one that protects against both types of sun rays (UVA and UVB) with an SPF of 15 or higher. It should be applied about 20 minutes before going outside, and more should be applied every two hours, or more often if sweating a lot or in water.
Tip 6: Avoid Going Alone (If Possible)
If one is exercising or working outdoors, especially in a quiet area, they should try not to go by themselves. If they must be alone, they should tell someone where they are going and when they expect to be back. Having someone else around means they can spot problems and get help if one starts to feel unwell.
Tip 7: Know When to Stop and Get Help
It’s important to know the signs of more serious heat problems. If an individual or someone else shows these signs, it’s an emergency:
- Feeling confused or acting strangely.
- Having a very high body temperature.
- Very hot, red, or dry skin (or sometimes very heavy sweating).
- A very fast pulse.
- Fainting or losing consciousness.
If these signs are seen, get help right away. The person should be moved to a cooler place, attempts should be made to cool them down with wet cloths or a hose, and emergency medical help should be called.
Being active or working outdoors in hot weather can be enjoyable and productive when done safely. By remembering to pick the right time of day, dress smart, drink plenty of water, and listen to the body, individuals can greatly reduce the chances of heat-related problems. Safety is important, so one should always plan ahead and take care of themselves in the heat.
