no, you cannot detect your own fever with your hand because your hand is the same body temperature as your forehead. Therefore, you can't feel if your forehead is hot or cold both are either hot at the same time or cold.
A clock
Yes it is very possible to feel the temperature if you slightly place the backside of your hand to the center of the forehead you can then feel if it is a higher temperature than normal.
Fate ;)
Is the temperature of your body. When is getting warmer your body temperature gets warmer and so you feel the drink colder then before - for a short time because eventually it will get warm too!!!
The temperature differences - if the water temperature is cooler than the temperature of your hand, your hand will lose heat to the water. Furthermore, when the remaining droplets of water on your hand evaporate, it will also take some of the heat it absorbed from your hand.

Body temperature is regulated by an intricate system called homeostasis. If the external (outside) temperature is hotter or colder than our body then various things come into play to maintain our body heat. If you put your hand into room temperature water (room temperature is generally accepted to be 20 degrees C) then it will feel cold, because body temp is about 37 degrees C. The water will absorb heat energy from your hand, making it feel cold, until the temperature of the water and the temperature of your hand are the same. Or until you decide that shoving your hand in cool water is pointless...If you put your hand into water that is at 37 degrees C then you won't notice any temperature difference. It just feels wet. It's really weird, try it!
Your breath evaporates the moisture which cools the surface temperature of the skin.
When you touch ice, it conducts heat away from your hand. This causes the temperature of your hand to drop, resulting in the sensation of coldness. Ice has a lower temperature than your body, so heat is transferred from your hand to the ice, making your hand feel cold.
The ice is colder then your hand so your hand starts heating up the ice which means your hand is losing warmth and it gets colder, then you have nerves in your hand which sense the lack of heat and you feel cold.
When water touches your hand, you may feel sensations such as wetness, coolness, and possibly a slight sensation of pressure or movement depending on the temperature and flow of the water.
The temperature of the water is lower than the air temperature. [Try running the hot water a little before you wash your hands.]
