Is "Hangry" Real?


When you’re overly hungry, your stomach isn’t the only thing that gets growly—empty bellies tend to make some of us more irritable. Snickers has even framed a successful marketing campaign around it.

But is hangry a real thing?

Absolutely. There’s a physiological reason that our mood drops when our hunger level goes up, and it involves your blood glucose. It’s the same reason why diabetics can become moody or confused when their blood sugar levels are low.

Our bodies process the food we eat into amino acids, fats, and simple sugars, like glucose. We use these nutrients for energy, and when they run out, our bodies respond accordingly. Specifically, the brain depends on glucose to function, so when those levels drop, your gray matter goes a little haywire. You may stutter or slur your words, find it hard to concentrate, and make simple mistakes. Your may feel dizzy, shaky, or anxious. Or you may get enraged about things you wouldn’t normally get angry about.

Some people have more trouble regulating their blood glucose than others, so they experience that hangry sensation more often, and more intensely, than others. The correlation between low blood sugar and anger is so strong, in fact, that a 1984 study was able to predict violence from people who had problems regulating their blood glucose.

Another factor that contributes to the hangry feeling is when your body tries to respond to the low blood sugar. When glucose runs low, your brain sends messages to certain organs to kick in to get your levels back up. This triggers your adrenaline, and adrenaline can make you rather quick to get angry.

So, the next time that hangry feeling strikes, what should you do? Eat, obviously—but not all food is created equal. A quick fix is to consume something really sugary—but that's also likely to cause a brief spike in your blood sugar, followed by a crash. Nutrient-rich foods that keep you sated for longer and stabilize your blood sugar are your best bet: Hummus, nuts, avocado, Greek yogurt, eggs, and cottage cheese are all great options.

What Does 'State of Emergency' Really Mean?

Local and state officials across the U.S. are declaring states of emergency in their efforts to manage the coronavirus pandemic. Some entire countries, including Italy and Japan, have also declared a state of emergency. But what does this phrase really entail?

Local and State Response

The answer varies a bit from state to state. Essentially, declaring a state of emergency gives the governor and his or her emergency management team a bit of extra latitude to deal with a situation quickly and with maximum coordination. Most of these powers are straightforward: The governor can close state offices, deploy the National Guard and other emergency responders, and make evacuation recommendations.

Other powers are specific to a certain situation. For example, in a blizzard, a governor can impose travel restrictions to clear roads for snowplows and other emergency vehicles.

Calling in the Feds

If a disaster is so severe that state and local governments don’t have the cash or the logistical ability to adequately respond, the governor can ask for a declaration of a federal emergency. In this case, the Federal Emergency Management Agency (FEMA) does a preliminary damage assessment to help determine whether the governor should petition the president for a federal emergency declaration.

When the declaration from the president comes through, state and local governments can get funding and logistical help from the feds. What makes a crisis a federal emergency? The list is pretty broad, but FEMA shares some criteria here.

Why Does Hand Sanitizer Have an Expiration Date?

The coronavirus pandemic has turned hand sanitizer from something that was once idly tossed into cars and drawers into a bit of a national obsession. Shortages persist, and people are trying to make their own, often to little avail. (DIY sanitizer may not be sterile or contain the proper concentration of ingredients.)

If you do manage to get your hands on a bottle of Purell or other name-brand sanitizer, you may notice it typically has an expiration date. Can it really go “bad” and be rendered less effective?

The short answer: yes. Hand sanitizer is typically made up of at least 60 percent alcohol, which is enough to provide germicidal benefit when applied to your hands. According to Insider, that crucial percentage of alcohol can be affected over time once it begins to evaporate after the bottle has been opened. As the volume is reduced, so is the effectiveness of the solution.

Though there’s no hard rule on how long it takes a bottle of sanitizer to lose alcohol content, manufacturers usually set the expiration date three years from the time of production. (Because the product is regulated by the Food and Drug Administration, it has to have an expiration date.)

Let's assume you’ve found a bottle of old and forgotten sanitizer in your house somewhere. It expired in 2018. Should you still use it? It’s not ideal, but if you have no other options, even a reduced amount of alcohol will still have some germ-fighting effectiveness. If it’s never been opened, you’re in better shape, as more of the alcohol will have remained.

Remember that sanitizer of any potency is best left to times when soap and water isn’t available. Consider it a bridge until you’re able to get your hands under a faucet. There’s no substitution for a good scrub.
