We all know the dangers of hot afternoons, but did you know that warm nights and mornings can also be hazardous to your health? Here's what to watch for.

When the TemperatureRadar indicates extreme heat is building, you may be concerned about the afternoon, but warm mornings can also be an issue.

The issue with warm mornings is that they make it more challenging to cool down. When temperatures only dip for a few hours, it can be difficult for those without access to air conditioning. Warm nights and mornings negatively impact sleep quality.

There are also health concerns. Warm nights and mornings increase the risk of heat exhaustion and heat stroke, especially when combined with high humidity. You can check morning temperatures using the TemperatureRadar.
