15. Thaw Your Brain Freeze
Press the tongue flat against the upper side of your mouth, and make sure you cover as much as you can. “Since the nerves in the roof of your mouth get extremely cold, your body thinks your brain is freezing, too,” explains Abo.
“In compensating, it overheats, causing an ice-cream headache.” The relieving depends on the pressure intensity -- the more pressure you apply, the faster your headache will disappear.
16. Stop The World From Spinning
Feeling dizzy can be really unpleasant. Put your hand on a stable surface. The cupula, the part of your ear responsible for the balance, floats in a fluid that has the same density as blood. “As alcohol dilutes blood in the cupula, the cupula becomes less dense and rises,” explains Dr. Schaffer.
In this way you will confuse your brain. The tactile input from the stable object will give your brain a second opinion, regulating your balance. As the nerves in the hand are quite sensitive, this method will sure work better than the traditional foot-on-the-floor technique.
17. Cold Water Will Calm You
You are tense and the nerves are sucking all your energy. You may find it crazy, but taking a deep breath and spashing some cold water in your face will sure do the trick. This trick activates the mammalian diving reflex, and all animals and humans have it. The cold water and holding your breath in will simulate diving into cold water. At least that is what your body would think. This diving reflex allows you to use the oxygen more efficiently.
18. Impress Your Friends
This trick will sure heat the atmosphere at your party. Pick a person and have him or her hold one arm straight out to the side (palm down), and explain them that they should maintain that position.
Place two fingers on their wrist and push down. The person will resist. Then instruct the person to put one foot on a surface that is half inch higher (a few magazines will do) and repeat. This time the arm will cave in.
Wonder what happened? Rachel Cosgrove, C.S.C.S., co-owner of Results Fitness, in Santa Clarita, California, says that by misaligning the person’s hips, you have offset the spine. The brain get signals that the spine is vulnerable, and shuts down the body’s resistance.
19. Breathe Underwater
If you can not retrieve the quarter from the bottom of the pool, just take a few short breaths first -- hyperventilate. It is not the lack of oxygen that makes you desperate to take a breath when you are underwater.
It is the carbon dioxide buildup that makes your blood acidic. This sends signals to your brain that something is wrong. “When you hyperventilate, the influx of oxygen lowers blood acidity,” says Jonathan Armbruster, Ph.D., an associate professor of biology at Auburn University. “This tricks your brain into thinking it has more oxygen.” This trick will buy you up to 10 seconds.
20. Wake Up You Sleeping Limbs
If your hands likes to take a nap while you are driving or sitting, just rock your head from side to side. It is a painless way to banish any pins and needles in less than a minute, according to Dr. DeStefano.
A compression in the bundle of the nerves in your neck often causes a tingly hand or arm. By loosening your neck muscles you will release the pressure. If this happens to your legs, just stand up and walk around, as the compressed nerves in the lower part of your body govern the feet.
21. Calm Your Heart
Is your heart getting excited about that first date? Blow on your thumb and you will be just fine. Ben Abo, an emergency medical-services specialist at the University of Pittsburg says that breathing can control the vagus nerve responsible for the heart rate. This simple method will get your heart back to normal.
