Blowing over hands after rubbing them on a snowy day

When you rub your hands together on a snowy day, the friction generates heat, but sometimes it may not be enough to warm up your hands completely. In such a situation, blowing air from the mouth over the hands can help to further warm them up.

How does it work?
- When you rub your hands together, the friction between them creates heat due to the conversion of mechanical energy into thermal energy.
- Blowing air from the mouth helps to transfer the body heat to the hands, providing additional warmth.
- The warm air blown onto the hands helps to maintain the elevated temperature achieved through friction, preventing rapid heat loss to the cold surroundings.

Benefits of blowing air over hands after rubbing them on a snowy day
- Provides additional warmth: The combination of friction-generated heat and warm air blown over the hands helps to raise and maintain their temperature.
- Prevents heat loss: Blowing air over the hands creates a barrier against the cold environment, reducing heat dissipation and keeping the hands warmer for a longer duration.
- Comfort and relief: The warm air not only warms up the hands but also provides a comforting sensation, alleviating the discomfort caused by the cold.

In conclusion, blowing air from the mouth over hands after rubbing them on a snowy day can be an effective way to warm them up further by transferring body heat and creating a barrier against heat loss.
