Is sleeping in Contact Lenses bad? | #aumsum


It’s AumSum Time Hi guys. Can you guess the title of my next video? Hurry up. Write your guess in the comments section below. Is sleeping in Contact Lenses bad? Not at all. They help us see our dreams more clearly. Stop bluffing. Contact lenses act like a sponge and absorb the moisture present in our eyes. They even trap bacteria. So, wearing them for too long, failing to
clean them periodically. Sleeping in them can cause excessive dryness and even eye infection. In addition to this, unlike other parts of our body. The cornea of our eye receives oxygen from the surrounding air and not from blood vessels. Now, when we wear contact lenses during the day, it reduces the oxygen supply to the cornea. But when we wear them while sleeping also, it further reduces the oxygen supply to the cornea. Hence, to satisfy the oxygen need, tiny blood vessels grow in the cornea, thus causing blurred vision. Why do our fingers get wrinkly? Because they want to look like raisins. No. A popular research suggests that wrinkly fingers are a reaction of our nervous system. When our fingers are in water for a long time. Our nervous system causes the blood vessels present in the deeper layers of our skin to constrict. This in turn causes the deeper layers to shrink or contract. But as the topmost layer does not shrink, it becomes loose thus, forming small folds or wrinkles. But why does this happen? Scientists suggest that this could be an evolutionary adaptation. Wrinkly fingers help in getting a better grip
to pick up wet objects. Preventing them from slipping from our hands. Even our feet get wrinkly, helping us to walk in water without slipping. What if we stopped drinking water? We will have to sell our water purifiers to
scrap dealers. You are unbelievable. About 60% to 80% human body is water. We need water for various purposes like digestion and excretion. Water is also a major component of blood. However, every day we lose about 2 to 3 liters of water through sweat, urine, breathing, etc. Hence, to compensate the water loss, if we
don’t drink enough water, then we will get dehydrated. During dehydration, our brain works harder
than normal. It informs kidneys to retain moisture, thus
producing darker concentrated urine. It reduces the production of saliva causing
dry mouth. Lack of water also causes our brain tissues to shrink. We get headaches and feel nauseous. Our energy levels drop and our skin becomes dry. Besides this, chronic dehydration can lead
to severe health problems and even death. Topic: Lunar Eclipse Why does the moon turn red? To scare us. No. Moon does not have light of its own. Why? Didn’t he pay the electricity bill. Please listen. Sunlight or white light is a mixture of visible colors. Now, when the sunlight falls on the moon,
it reflects all these visible colors equally. Making the moon to mostly appear white. However. During a lunar eclipse when the earth is exactly between the sun and the moon, the moon appears red. This happens because of the earth’s atmosphere. When the sunlight coming from the sun passes through the earth’s atmosphere. The earth’s atmosphere scatters the colors of the sunlight having shorter wavelengths. However, red color which has the longest wavelength is least scattered. Hence, it makes its way to the moon, making it look red. Are preservatives bad for you? I don’t know what they are. So, they must be good for me. No. Wait, I’ll explain. A preservative is a substance added to foods, cosmetics, medicines, etc. To prevent them from spoiling. For example, preservatives like salt and sugar prevent the growth of harmful microbes in foods Thus preventing them from spoiling. However. A high amount of salt and sugar can increase the risk of diabetes, high blood pressure, heart diseases, etc. Some food items even have preservatives like benzoic acid to inhibit the growth of harmful microbes. But benzoic acid is said to cause hyperactivity in children, asthma, etc. Sorbic acid which is used in cosmetics can
cause skin irritation. In people suffering from asthma, preservatives like sulfites can cause very serious problems. Like difficulty in breathing, tightness in
chest, etc. Hence, it is very important to check the preservatives used and have them in moderate amounts.
