Q. What is the difference between complete and incomplete ventilation?
Doctor Answer is medically reviewed by SecondMedic medical review team.
The difference between complete and incomplete ventilation lies in the type of air exchange taking place. Complete ventilation involves the full exchange of air inside a building with air from outside, while incomplete ventilation only involves exchanging part of the interior air with outdoor air. In short, complete ventilation replaces all the indoor air with new outdoor air, while incomplete ventilation mixes some fresh outdoor atmosphere into stale interior atmosphere.
Complete ventilation is often found in office buildings and residential homes, as it helps to continuously remove pollutants from indoor spaces. It also helps to ensure that a healthy level of oxygen is maintained for occupants throughout the day. As a result, it can improve productivity levels and reduce fatigue among workers due to better-quality air circulation inside an enclosed area or building.
Incomplete or spot ventilating systems are often employed when fresh exterior airflow cannot be supplied evenly over an entire space or building but rather just at one point of entry (e.g., an open window). While they are not as effective at improving overall indoor quality compared to complete systems, they still make use of natural convection currents that cycle polluted indoor atmosphere out through windows or vents in order to achieve some level of additional aeration indoors. This form ofventilation is commonly used when multiple rooms need different amounts of fresh external breathable hours depending on their needs and activities taking place within them (i.e., cooking vs sleeping for example).
Overall, appropriate choice between these two types will depend on specific requirements such as size/type/functionalityof space being discussed but ultimately should always aim at achieving maximum possible health benefitfor occupants by ensuring sufficient quantitiesof clean externalairare availableatall times soas toprovide optimal breathing conditions indoors duringoccupancy periods!
Q. Hello Doctor, from past 3 weeks I have too much dandruff problem and it cause hair loss will you suggest any best solution for this?

Answered by Secondmedic ExpertDealing with excessive dandruff leading to hair loss can be frustrating, but there are effective ways to address this issue. Here's what you can do:
1. Switch to a Gentle Shampoo: Opt for shampoos specifically designed for dandruff, containing ingredients like ketoconazole, zinc pyrithione, coal tar, or selenium sulfide. Use these shampoos regularly to reduce dandruff buildup.
2. Scalp Massage: Gently massage your scalp while shampooing to help remove flakes and improve blood circulation, which can promote healthier hair growth.
3. Avoid Hot Water: Wash your hair with lukewarm water instead of hot water, as hot water can dry out your scalp and worsen dandruff.
4. Balanced Diet: Ensure you're eating a balanced diet rich in vitamins and minerals essential for healthy hair and scalp, such as omega-3 fatty acids, zinc, and B vitamins.
5. Manage Stress: Stress can exacerbate dandruff problems. Practice stress-relief techniques like meditation, yoga, or regular exercise to help manage stress levels.
6. Apple Cider Vinegar Rinse: Consider using diluted apple cider vinegar as a rinse after shampooing. It can help restore the scalp's pH balance and reduce dandruff.
7. Consult a Dermatologist: If the issue persists despite trying home remedies or over-the-counter solutions, seek advice from a dermatologist. They can provide a personalized treatment plan tailored to your specific scalp condition.
Remember, consistency is key when dealing with dandruff. Give these remedies some time to work, as immediate results might not always occur. It's essential to find what works best for your scalp, so don't get discouraged if you don't see immediate improvements.
Taking care of your scalp health not only addresses dandruff but also aids in reducing hair loss associated with this issue. Feel free to incorporate these tips into your routine and observe how your scalp responds. If the problem persists or worsens, seeking professional guidance is always recommended.
