Hello,
The battery in my M1 MacBook Air has only 45 cycles, and the health already is on 95%. Is this normal? I've been using the machine for only a few months and I'm worried about the battery health dropping so fast despite so few cycles.
MacBook Air 13″, macOS 12.3
It's within tolerances.
The maximum charge capacity of lithium-polymer batteries does not decrease in a linear fashion. It may even increase from time to time, although the long term trend is down.

Apple won’t replace the battery until it reaches 80% capacity, then it’s a possible free replacement. 😉
—In the meantime:—
Update to the latest software.
Always make sure your MacBook is using the latest version of macOS. If you’re connected to the Internet, macOS automatically checks for software updates every week, but you still control when the updates are installed. To confirm that you’re using the latest software, go to the Apple menu and choose Software Update.

Optimize your settings.
Energy. The Energy Saver preference pane includes several settings that determine power levels for your MacBook. Your MacBook knows when it’s plugged in and runs accordingly. When using battery power, it dims the screen and uses other components sparingly. If you change this setting to maximize performance, your battery will drain more quickly.
Brightness. Dim the screen to the lowest comfortable level to achieve maximum battery life. For instance, when watching a video on an airplane, you may not need full brightness if the cabin lights are off.
Wi-Fi. Wi-Fi consumes power, even if you are not using it to connect to a network. You can turn it off in the Wi-Fi status menu in the menu bar or in Network preferences.
Applications and peripherals. Disconnect peripherals and quit applications not in use. Eject an SD card if you’re not currently accessing it.
Plug in and power on your MacBook to charge other devices.
Make sure your MacBook is plugged in and powered on when you’re using it to charge other devices via USB. Otherwise those devices may drain the battery in your MacBook faster than normal. If another device is connected to your MacBook when it’s turned off or in sleep or standby mode, the device’s battery may drain.
