Humidity and Dry Air in Your Home The science behind every Venta Airwasher Humidity and How it Improves Your Indoor Air The Effects of Dry Air Dry heater air causes dry mucous membranes. The danger of infection, catching cold, and allergic respiratory disease increases due to this. Breathing dry air is harder on the lungs and makes it more difficult for oxygen to enter the blood. Symptoms can include tiredness, headache and reduced concentration. Wooden furniture, parquet floors and musical instruments can crack when exposed to dry air. The indoor air can contain millions of fine particles invisible to the naked eye. Dust also rises in dry air. Humidification is important as heating causes dry air. A heated 300 sq. ft. room needs approximately 5 liters of water per day to have the medically recommended humidity level. Water bowls on heaters are much too small and unhygienic. There are various humidifying systems for humidifying the air to the optimal level, but a Venta Airwasher is the best humidifier and air purifier for allergies, dust, and mold.

How the Venta Airwasher Works The Physics of Humidifying Humidity is the proportion of water vapor in the air. There are two kinds of humidity: absolute humidity and relative humidity. Absolute humidity is a measurement for the maximal possible content of water vapor in the air. It is given in grams per cubic meter (g/m³). This value depends on the temperature of the air, since warm air can absorb more moisture than cold air can. This is why the maximal air moisture level is higher in the summer than in the winter. The relative humidity (RH) is the ratio of water vapor content to the maximal possible water vapor content. The relative moisture is given as a percentage. When the air is saturated, the relative humidity is therefore 100%. The following table and figure show how much water (absolute value) can be absorbed by air at various temperatures. At 20 °C, the air has a maximal water vapor content of 17.3 g/m³. This means that during the colder times of year in particular, during which there is a major difference between the temperature of the air indoors and outside, water must be actively added to the air.

In a room heated to 25 °C, the air can absorb 23 g/m³ of water, while 0 °C cold air cannot absorb much moisture and only contains 4.84 g/m³ of water. air conditioning cleaning miamiOpening the windows during the colder times of year makes the air inside even drier, since the cold air from outside hardly contains any water and requires more moisture once it has been heated.air purifier diamond Saturation Concentration of Steam in the Air as a Function of Temperature.air purifier from germany The Venta Airwasher Helps to Solve Your Problems Benefits of using Venta Airwasher Home > Health topics A-Z > Dry Eye: Treatment Click for more information Try over-the-counter remedies such as artificial tears, gels, gel inserts, and ointments.

They offer temporary relief and can provide an important replacement of naturally produced tears. Avoid remedies containing preservatives if you need to apply them more than four times a day or preparations with chemicals that cause blood vessels to constrict. Wearing glasses or sunglasses that fit close to the face (wrap around shades) or that have side shields can help slow tear evaporation from the eye surfaces. Indoors, an air cleaner to filter dust and other particles can help your eyes feel more comfortable. A humidifier also may help by adding moisture to the air. Allow your eyes to rest when doing activities that require you to use your eyes for long periods of time. Use lubricating eye drops while performing these tasks. If symptoms of dry eye persist, consult an eye care professional to get an accurate diagnosis of the condition and begin treatment to avoid permanent damage. Goal of TreatmentDry eye can be a temporary or ongoing condition, so treatments can be short term or may extend over long periods of time.

The goal of treatment is to keep the eyes moist and relieve symptoms. (This short video discusses causes, symptoms, and treatments for dry eye.) Talk to your doctor to rule out other conditions that can cause dry eye, such as Sjögren's syndrome. You may need to treat these conditions. If dry eye results from taking a medication, your doctor may recommend switching to a medication that does not cause dry eye as a side effect.Cyclosporine, an anti-inflammatory medication, is a prescription eye drop available to treat certain kinds of dry eye. In people with certain kinds of dry eye, it may decrease damage to the cornea, increase basic tear production, and reduce symptoms of dry eye. It may take three to six months of twice-a-day dosages for the medication to work. Some patients with severe dry eye may need to use corticosteroid eye drops that decrease inflammation.In some patients with dry eye, supplements of omega-3 fatty acids (especially ones called DHA and EPA) may decrease symptoms of irritation.

Talk with your eye care professional or your primary medical doctor about whether this is an option for you.If dry eye is a result of wearing contact lens for too long, your eye care practitioner may recommend another type of lens or reducing the number of hours you wear your lenses. In the case of severe dry eye, your eye care professional may advise you not to wear contact lenses at all.Another option to increase the available tears on the eye surface is to plug the small circular openings at the inner corners of the eyelids where tears drain from the eye into the nose. Lacrimal plugs, also called punctal plugs, can be inserted painlessly by an eye care professional. These plugs are made of silicone or collagen. These plugs can be temporary or permanent.In some cases, a simple surgery called punctal cautery is recommended to permanently close the drainage holes. The procedure works similarly to installing punctal plugs, but cannot be reversed.Dry eye syndrome (DES or dry eye) is a chronic lack of sufficient lubrication and moisture on the surface of the eye.

Its consequences range from minor irritation to the inability to wear contact lenses and an increased risk of corneal inflammation and eye infections. Signs and Symptoms of Dry Eye Persistent dryness, scratchiness and a burning sensation on your eyes are common symptoms of dry eye syndrome. These symptoms alone may be enough for your eye doctor to diagnose dry eye syndrome. Sometimes, he or she may want to measure the amount of tears in your eyes. A thin strip of filter paper placed at the edge of the eye, called a Schirmer test, is one way of measuring this. Some people with dry eyes also experience a “foreign body sensation” – the feeling that something is in the eye. And it may seem odd, but sometimes dry eye syndrome can cause watery eyes, because the excessive dryness works to overstimulate production of the watery component of your eye’s tears. In dry eye syndrome, the tear glands that moisturize the eye don’t produce enough tears, or the tears have a chemical composition that causes them to evaporate too quickly.

Dry eye syndrome has several causes. If your home or office has air conditioning or a dry heating system, that too can dry out your eyes. Another cause is insufficient blinking, such as when you’re staring at a computer screen all day. Dry eyes are also associated with certain systemic diseases such as lupus, rheumatoid arthritis, rosacea or Sjogren’s Syndrome (a triad of dry eyes, dry mouth, and rheumatoid arthritis or lupus). Long-term contact lens wear, incomplete closure of the eyelids, eyelid disease and a deficiency of the tear-producing glands are other causes. Dry eye syndrome is more common in women, possibly due to hormone fluctuations. Recent research suggests that smoking, too, can increase your risk of dry eye syndrome. Dry eye has also been associated with incomplete lid closure following blepharoplasty – a popular cosmetic surgery to eliminate droopy eyelids. Dry eye syndrome is an ongoing condition that treatments may be unable to cure.

But the symptoms of dry eye – including dryness, scratchiness and burning – can usually be successfully managed. Your eyecare practitioner may recommend artificial tears, which are lubricating eye drops that may alleviate the dry, scratchy feeling and foreign body sensation of dry eye. Prescription eye drops for dry eye go one step further: they help increase your tear production. In some cases, your doctor may also prescribe a steroid for more immediate short-term relief. Another option for dry eye treatment involves a tiny insert filled with a lubricating ingredient. The insert is placed just inside the lower eyelid, where it continuously releases lubrication throughout the day. If you wear contact lenses, be aware that many artificial tears cannot be used during contact lens wear. You may need to remove your lenses before using the drops. Wait 15 minutes or longer (check the label) before reinserting them. For mild dry eye, contact lens rewetting drops may be sufficient to make your eyes feel better, but the effect is usually only temporary.

Switching to another lens brand could also help. Check the label, but better yet, check with your doctor before buying any over-the-counter eye drops. Your eye doctor will know which formulas are effective and long-lasting and which are not, as well as which eye drops will work with your contact lenses. To reduce the effects of sun, wind and dust on dry eyes, wear sunglasses when outdoors. Wraparound styles offer the best protection. Indoors, an air cleaner can filter out dust and other particles from the air, while a humidifier adds moisture to air that’s too dry because of air conditioning or heating. For more significant cases of dry eye, your eye doctor may recommend punctal plugs. These tiny devices are inserted in ducts in your lids to slow the drainage of tears away from your eyes, thereby keeping your eyes more moist. If your dry eye is caused by meibomian gland dysfunction (MGD), your doctor may recommend warm compresses and suggest an in-office procedure to clear the blocked glands and restore normal function.

Doctors sometimes also recommend special nutritional supplements containing certain essential fatty acids to decrease dry eye symptoms. Drinking more water may also offer some relief. If medications are the cause of dry eyes, discontinuing the drug generally resolves the problem. But in this case, the benefits of the drug must be weighed against the side effect of dry eyes. Sometimes switching to a different type of medication alleviates the dry eye symptoms while keeping the needed treatment. In any case, never switch or discontinue your medications without consulting with your doctor first. Treating any underlying eyelid disease, such as blepharitis, helps as well. This may call for antibiotic or steroid drops, plus frequent eyelid scrubs with an antibacterial shampoo. If you are considering LASIK, be aware that dry eyes may disqualify you for the surgery, at least until your dry eye condition is successfully treated. Dry eyes increase your risk for poor healing after LASIK, so most surgeons will want to treat the dry eyes first, to ensure a good LASIK outcome.
