A temperature of 65°F (18.3 degrees Celsius) is considered the best for sleeping. However, it might vary in a few degrees as per a person’s individual preference.

But most doctors keep the thermostat set around 60 to 67°F, which is (15.5 to 19.4 degrees) to get the most comfortable sleep.

This temperature is recognized as the most suitable for sleeping due to its ability to relate to your body’s internal temperature regulation. After 24 hour period, the body’s internal temperature witnesses a shift called a circadian rhythm.

Our body is programmed to witness a change or a dip in the core temperature during the evening time. Turning the thermostat down at night may assist in temperature regulation and indicate to your body that it’s for sleep.

During the time for your bed, your body begins to shed warmth, and it continues until it reaches its low point near the daybreak, which is around 5 a.m. The body then cools by increasing the blood vessels in your skin.

During the nighttime, when the temperature starts to fall, you might feel your feet and hands get a bit warmer. This warmness takes place your body starts to let the heat escape through the body to decrease your core temperature.

If the temperature around you is either too cold or hot, it might affect the drop in internal temperature of your body and can result in disrupted sleep.

You are not really required to make massive changes in terms of temperature for babies as babies usually benefit from a room temperature that is one or two degrees warmer up to 68°F.

Bodies of babies are small and still at a developing stage, due to which they are more sensitive to the changes in ambient temperature.

However, you need to make sure the temperature isn’t too warm for babies as it can enhance the chances of sudden infant death syndrome.

Therefore, it is recommended to have a favourable temperature by setting a thermostat, using approved and comfortable sleepwear, and not using any heavy blankets.

You should always check your baby’s temperature by touching the back of their neck or stomach at night. According to research, babies usually achieved temperature maturation on average of eleven weeks of age.

They start to have a minimum core body temperature of around 97.5°F within four hours of their bedtime, quite the same as adults.

So, if you witness the baby’s temperature too hot or sweaty, you can remove the clothing layer, and yet if you notice them being hot, you should consult a doctor. For a healthy sleep, babies should sleep in a quiet and dark environment.
