This!
Stop running outside at 3pm in 105 degrees to "save" those wilting squash plants.
They are doing what they are supposed to and they are just fine.

Tip: Resist the urge to overwater on hot afternoons!
Master Gardener Eugene Wong explains, on hot afternoons, it is natural to see some plant with droopy leaves. It is also natural to want to immediately give it some water. But stop, just for a moment. Poke a finger into the soil near the root to see if the soil is still moist. If it is moist, wait until the next morning to water the plant.
What may be happening is the wilting is only temporary for plants that have adequate soil moisture on hot days. Many plants with large leaves such as squash, cucumber, sunflower, and many others may droop because they cannot absorb water fast enouh through their roots to replace the water lost through their leaves.
Adding water at this time is not necessary and may actually be harmful to the plant in some case since the extra water may prevent oxygen from reaching the roots. Plants will often recover in the evening as it cools down. One of the reasons to water plants early in the morning is to allow the soil to partially dry out and allow oxygen to refill tiny airspaces in the soil. Roots take in this oxygen from the soil as part of its processes to make use of available nutrients. Suffocating roots contribute to poor growth and may kill the plant.
