What happens during a heat wave?
A heatwave occurs when a system of high atmospheric pressure moves into an area and lasts two or more days. In such a high-pressure system, air from upper levels of our atmosphere is pulled toward the ground, where it becomes compressed and increases in temperature.
What should you not do during a heat wave?
Don’t drink alcohol, sugary soda, coffee, energy drinks, or other caffeinated beverages, as they dehydrate you! That’s the last thing you need during a heat wave. Eat small meals and eat more often. Eat food with nutrients (not empty carbs) and also food with higher water content (fruits and vegetables).

What conditions are needed for a heat wave to form?
Heat waves form when high pressure air settles high in the air and causes hot air to sink down. The hot air sinking creates a bubble that acts like a seal and traps heat near the ground.
What causes heat waves?
Heat waves begin when high pressure in the atmosphere moves in and pushes warm air toward the ground. That air warms up further as it is compressed, and we begin to feel a lot hotter. This is also why a heat wave parks itself over an area for several days or longer.
