Why Does Everything Go Black When You Stand Up Too Fast?

Almost everyone has experienced it. You stand up from the couch, your vision suddenly fades, everything turns gray or black for a few seconds, and sometimes you even feel dizzy. It feels strange, but there's actually a simple explanation.

When you stand up quickly, gravity pulls blood toward your legs. For a brief moment, less blood reaches your brain. Since your brain depends on a constant supply of oxygen, even a short drop in blood flow can make your vision fade or cause dizziness. Your body reacts almost instantly by making your heart beat faster and tightening your blood vessels to restore normal blood pressure. In most healthy people, the whole process only takes a few seconds.

This is called orthostatic hypotension. It can happen more often if you're dehydrated, haven't eaten for a long time, are very tired, have been lying down for a while, or take certain medications.

Most of the time it's harmless. But if it happens frequently, causes you to faint, or starts occurring for no obvious reason, it's worth getting checked by a healthcare professional.

Your eyes aren't failing.

Your brain is simply waiting for the blood to catch up.

No Defrosting in 8 years

It appears previous tenants never bothered to take care of the fridge. Iceberg bigger than the one who sunk the Titanic. The block ended up coming off, glad I didn’t have to deal with this amount of water.

Take care of your appliances friends

A small house for sale in Kamchatka

These are just real photos of a small house for sale in Petropavlovsk-Kamchatsky, the main city of Kamchatka. I was curious to see it, and I thought maybe someone else would be interested. The house was built in 1959 and measures 68 square meters (732 square feet) with two bedrooms. It has central water and sewerage. It's built right on a hill, so residents will have to park their cars in the garage downstairs and climb a long flight of stairs into the house. However, the terrace overlooks the bay from the side house and offers panoramic views of the city center. The house is being sold fully furnished and equipped, ready to move in. The price is 6.1 million rubles, or just under $80,000. It's not much, but many are currently worried about falling real estate prices in Russia. On the other hand, Kamchatka is in the Far East and is practically untouched by the military actions currently taking place in the European part of Russia. Which, in the current situation, can be considered a significant advantage.

Bijzondere ontmoeting: een roze sprinkhaan in de tuin

We moesten even twee keer met onze ogen knipperen toen we vorige week een roze sprinkhaan in de tuin van mijn broertje spotten. Blijkbaar is de kleur een gevolg van een genetische afwijking en is het een uniek verschijnsel. Wat is het meest bijzondere dat jullie in jullie tuin hebben gezien?
