every time i use my nintendo switch, in handheld to play games it gets warm

It's normal for the Nintendo Switch to get warm during use, especially when playing graphically intensive games or when the console is charging. Here are a few reasons why your Switch may be warming up and some tips to manage it:

### Why the Switch Gets Warm:
**Processor Load**: GPUs and CPUs get hot when running demanding games, leading to heat production.
**Long Play Sessions**: Extended gaming sessions can lead to increased heat accumulation.
**Ventilation**: If the device is obstructed or covered, it may not dissipate heat effectively.
**Ambient Temperature**: Warmer room temperatures can also contribute to how hot the device feels.
**Charging**: If you're charging the device while playing, it will naturally generate more heat.

### Tips to Manage Heat:
**Use in a Cool Environment**: Ensure you’re in a well-ventilated and cooler area while playing.
**Take Breaks**: Allow the console to cool down by taking breaks during long gaming sessions.
**Avoid Covering Vents**: Ensure that the Switch’s air vents are not blocked. Avoid using it on soft surfaces (like beds or couches) that can obstruct airflow.
**Clean It**: Dust and debris can accumulate in the vents; occasionally cleaning them can improve airflow.
**Lower the Brightness**: Reducing screen brightness can decrease the load on the battery, which may help keep it cooler.
**Disable Unused Features**: Turn off features like Bluetooth or Wi-Fi if you’re not using them.
**Remove Accessories**: If you have accessories like a case or grip that covers the console, consider removing them while playing to improve ventilation.

If your Nintendo Switch starts to overheat to the point of impacting performance or shutting down, it’s a good idea to consult Nintendo's customer support for further assistance.
