There are simple ways that you can stop from tearing up when you are around onions. The tearing up mechanism happens because when you cut into an onion, its cells rupture and releases enzymes that produce a gas called propanethial sulfoxide. When the gas reaches your eyes, it reacts with tears to produce a mild sulfuric acid. The brain signals the eyes' tear glands to produce more liquid to flush it out. The more that onions are chopped, the more your eyes tear up.
It is a good idea to chill an onion in the freezer before cutting it because cold temperatures can slow down the release of enzymes. You can also pour a tablespoon of vinegar onto the cutting board. The acid in the vinegar stops the chemical reaction of the sulfur in the onion and causes a reduction in tears. It is another good idea to put an onion under water before chopping it. The water would absorb the onion's gas.

Safe Tips to Sleep Better
There are several things that you can do to help you to sleep better at night. You can avoid alcohol before bedtime, avoid caffeine, turn down the thermostat, increase carbohydrate intake, and develop a sleep schedule.
It is not good to drink alcohol before trying to go to sleep. Alcohol can have a negative effect on the quality of sleep. Even small or moderate amounts of alcohol can suppress melatonin, which is a hormone that helps to regulate sleep. It also interferes with the monoamine transmitters that controls the body's ability to sleep well. Alcohol can also interfere with restorative N-REM cycles and prevent a person from dreaming by disrupting the second half of the sleep cycle.
Eliminating caffeinated drinks from your diet can help you to sleep better. Caffeine can have a negative effect on sleep by boosting a person's alertness, activate stress hormones, and increase heart rate and blood pressure. It is good to to drink a caffeinated drink at least 8 hours before your bedtime.
Keeping your bedroom or the area where you sleep cool and dark can help you to sleep better. The recommended temperature is between 54 and 75 degrees Fahrenheit. A cool room makes it easier for the body's core temperature to drop, which is needed to be able to fall asleep. The body reaches its lowest temperature about 4 hours after a person falls asleep. Researchers have found that when the hands and feet are warm it causes blood vessels to dilate and heat to escape and body temperature to decrease, which could help a person to fall asleep faster.
Increasing the amount of starchy carbohydrates in your diet, such as cereal, pasta, and potatoes, can increase the ability of sleep causing amino tryptophan in the blood, which increases serotonin. Serotonin is a brain neurotransmitter that promotes sleep. Foods high in complex carbohydrates, such as bread, bagels, and crackers, can have a mild effect on sleep.
It can help to develop a regular sleep and wake schedule. That would mean going to bed and waking up at the same time everyday so that your body would regulate itself to fall asleep asleep at a certain time and wake up at a certain time.

ThermoSuit for Cardiac Arrest Patients
When a person has been revived after cardiac arrest but is still unconscious, cooling the body is the first thing done by emergency staff. Reducing the body temperature would improve the patient's chance for a full recovery. Blowing cold air over the body or using ice packs can take hours to work effectively.
Now, there is a product called a ThermoSuit that can reduce a person's body temperature in about 30 minutes. The product is a plastic suit that is filled with cold water. There are medical centers that are currently using it and say that the survival rate of their cardiac arrest patients has risen from 35 percent to 60 to 70 percent.

New Medical Treatment for Heart Attacks
It is assumed that if a person is not revived 5 minutes after having cardiac arrest that they are basically dead. Researchers have found that if the body of a person that had cardiac arrest is cooled by several degrees after the heart has stopped beating, the person could survive for up to 15 minutes instead of 5 minutes. Doctors are starting to use cooling blankets that circulate icy water to reduce brain damage and revive people that didn’t have a heart beat for up to 15 minutes. Researchers are trying to develop icy injectable slurry that lowers body temperature within seconds and emergency workers can use it on the spot.
