you have lots of sex im doing it right now to warm my blood
The hunter's reflex is a physiological condition whereby in cold weather the blood vessels in the forearm allow blood to flow to the hands thus keeping them warm and useful, rather than the normal response which is to withdraw blood from the extremities to protect the core.
Fluids help you blood circulate efficiently which in turn helps your body to stay warm.
The air flows through the unit helping to move the heat. Heat rises, pulling air behind it through the exchanger, but the air movement is minimal. The more air flow through circulation, say by a fan, the more cool air can be moved through and heated.
When hypothermia sets in, the body's survival mechanisms kick in to protect vital organs by constricting blood vessels in non-essential parts of the body like the skin and limbs. This redirection of blood flow helps to maintain core body temperature and preserve circulation to critical organs such as the heart, brain, and lungs. The body also slows down processes in these non-essential areas to conserve energy and focus on keeping the vital organs warm.
In warm weather, we may need to stay hydrated, wear light, breathable clothing, and protect our skin from the sun. In cold weather, we may need to stay warm by layering up, staying dry, and protecting our extremities from the cold. Hydration is still important in cold weather to prevent dehydration.
Your hands are warm because of the blood flow in your body. Blood carries heat from your core to your extremities, like your hands, to keep them warm and functioning properly.
The hunter's reflex is a physiological condition whereby in cold weather the blood vessels in the forearm allow blood to flow to the hands thus keeping them warm and useful, rather than the normal response which is to withdraw blood from the extremities to protect the core.
Vasoconstriction is the closing of arteries supplying blood to the bodies extremities. As the extremities are the coldest bits of the body, when the arteries constrict less heat is lost from the blood in these areas. This keeps the core of the body warm.
I can't find any evidence that adderall thins the blood, but from personal experience, when I take adderall my extremities get very cold, like my hands and feet get very cold even if it is a warm day outside. so I am not sure if it thins your blood or not but it definitely seems to make your extremities cold and that kinda seems like maybe it is thinning you blood.
it stimulates the blood vessels in your skin, causing increased circulation, thus keeping your feet warm

Peripheral vasoconstriction is the narrowing of blood vessels in the body's extremities, reducing blood flow to these areas. This helps to conserve heat by redirecting warm blood to the body's core organs, where it is needed the most for maintaining core temperature.
Chilblains are small, itchy, painful swellings on the skin that occur as an abnormal reaction to cold temperatures. They typically affect the extremities such as the toes, fingers, ears, or nose. Keeping warm and avoiding rapid temperature changes can help prevent chilblains.
Since blood heats the skin, and in the cold the body wants to keep the core warm, it reduces circulation to the extremities which can cause frostbite.
The hunter's reflex is a physiological condition whereby in cold weather the blood vessels in the forearm allow blood to flow to the hands thus keeping them warm and useful, rather than the normal response which is to withdraw blood from the extremities to protect the core.
Vasoconstriction, the tightening/narrowing of blood vessel diameter, is the "how" blood flow is limited when it's cold. The "why" deals mainly with your body attempting to keep its core warm. So anything around your heart mainly. Therefore, all extremities get less blood.
They get narrower therefore less blood flows through vessels. The body will try to keep the core warm. Doing so will cause the extremities to become less so.
