So the consensus online is that babies should sleep in a room with a temperature between 16 to 21 degrees.
But there are millions of babies born in hot tropical climates to families with low income, where the temperature even at night time will be 28-32 degrees Celsius. So obviously they do not sleep at 16 to 21 degrees, but are fine. So what is the deal here? How can this contradict the common recommendation? What happens if a person from a cold climate has a baby with a person from a tropical climate, and the baby is born in the tropical climate. Is it then okay for the baby to sleep in a room at 28 degrees?
