Chip running hot on blink sketch

Well @maze1980 and @allObjects I do understand sleep vs setInterval + event loop in JS differnces.

Still I don't understand why following code in micropython:

led = Pin(13, Pin.OUT)

def blink():
  led.value(not led.value())  
 
t = time.ticks_ms();
while True:
  if (time.ticks_ms() - t >= 1000):
    blink();
    print((esp32.raw_temperature() - 32) * 0.5556)    
    t = time.ticks_ms()

produces same 51 C

I clearly I'm not putting ESP to sleep, and in a sense it's more or less what main event loop + setInterval would be doing.
