Generally maintain the room temperature at 22-26 ℃ is more suitable for babies to sleep, but the temperature needs to be adjusted with the actual situation of the baby, parents can touch the baby’s back whether sweating to determine whether the temperature is suitable for babies. Babies need a more suitable temperature and humidity to ensure the quality of sleep and promote physical growth and development because of their poor self-regulation ability, and it is generally recommended to maintain 22-26℃ and 50%-60% humidity is a more suitable range. Because babies may not be able to express themselves in time, parents need to pay attention to observe the baby’s sleep state. You can judge by touching your baby’s back while he or she is sleeping. If the back is not sweating, it means that the environment and the temperature are suitable. If sweating is present, the temperature is high and can be lowered so that it can be adjusted to the right state. If the back is found to be cooler as well as other parts of its body, it means that the temperature is lower and should be raised appropriately. In addition, we should pay attention to keep the room temperature constant, do not suddenly increase or decrease, so that the baby’s temperature is too high and the body temperature rises, the volume of urine decreases, and even dehydration and electrolyte disorders. The low temperature will lower the baby’s own body temperature, which is also not conducive to growth and development. When using air conditioning to adjust the temperature, you should avoid air conditioning blowing directly on the baby, while protecting the baby’s stomach to avoid diarrhea due to cold.
