No. It's a physical change
Sweating from the forehead is a normal physiological response to regulate body temperature. When your body heats up, the sweat glands in your forehead produce sweat to help cool you down. Factors like exercise, stress, or hot weather can lead to increased sweating from the forehead.
Other body areas with high density of sweat glands include the palms of the hands, the soles of the feet, and the forehead. These areas are known for having a high concentration of eccrine sweat glands, which are responsible for controlling body temperature through sweat production.
The forehead has a higher density of sweat glands compared to the forearm. This is because the forehead is an area of the body that is more prone to overheating and requires more efficient cooling through sweat production.
Sweat is primarily prevented from dripping into your eyes by the brow ridge and the natural contour of your forehead, which help direct sweat away from your eyes. Additionally, many people employ techniques like wiping their forehead with a towel or using sweatbands. The body also produces less sweat in cooler conditions, further reducing the likelihood of it running into the eyes.
The skin is the organ where water is lost as sweat.
Sweat evaporating is considered a physical change because it is a change in the state of matter from liquid (sweat) to gas (water vapor) without altering the chemical composition of the substances involved. The molecules in sweat retain their chemical identity during the process of evaporation.
no
perspiration on the forehead is secretion of sweat from sweat glands. Example: perspiration on the forehead is there for a simple purpose, cooling down the head.
No, the evaporation of sweat is a physical change, not a chemical change. Evaporation simply involves a change in state from liquid to gas, without any change in the chemical composition of the substance.

Sweating and evaporating are similar because evaporating is the change of liquid water to water vapour, which requires heat, and sweating is where the skin produces liquid sweat, which is a mixture of water and other substances, which absorbs heat from your skin as it is transformed into a vapour. As you see, when you sweat your sweat is actually evaporated into the air, while absorbing your body and cooling you off!!
Sweat and bacteria
Yes, pregnant or not we have sweat glands there. It's not typical for pregnancy.
Sweat cools you down by evaporating from your skin, taking away heat and lowering your body temperature.
Yes, your long hair and sweat does affect your acne. The dirt in your hair and sweat gets trapped in your pores.
