Cutting Grass During Heat Wave: Tips for Success

Cutting grass during a heat wave can be a daunting task, but with the right approach, you can get the job done safely and efficiently.

The key is to plan your mowing session for early morning or late evening when the sun is not too intense. This helps prevent heat-related illnesses like heat exhaustion and heat stroke.

According to the American Red Cross, the risk of heat-related illnesses increases when the temperature is above 90°F (32°C) and humidity is high.

It's also essential to drink plenty of water before, during, and after mowing to stay hydrated. Aim for at least 8-10 glasses of water per day.
