🤔 How it works …….. ⁉
How an Ear hearing aid works 🦻🏻
A hearing aid has three basic parts: a microphone, amplifier, and speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker.
The sound waves are gathered by the outer ear and sent down the ear canal to the eardrum. The sound waves cause the eardrum to vibrate, which sets the three tiny bones in the middle ear into motion. The motion of the bones causes the fluid in the inner ear or cochlea to move. cochlea, causes changes in tiny structures called hair cells.
*How we can lose our hearing*
The path between your outer ear and your brain can be blocked or damaged in many different places and in a number of different ways, so people can become deaf or lose some or all of their hearing for lots of different reasons. One of the most common types of hearing loss happens when the hairs in the cochlea become damaged. If there are fewer hairs, sounds produce less stimulation in your brain—so things need to be louder for you to hear them.
That’s where hearing aids come in. They can’t help everyone with impaired hearing, but they can often make a difference to hearing problems caused by a loss of cochlear hair cells or damage to other parts of the inner ear.

What Is Vitiligo? Why it happens
Vitiligo is a condition in which white patches develop on the skin. Any location on the body can be affected, and most people with vitiligo have white patches on many areas.
Vitiligo is caused by the lack of a pigment called melanin in the skin. Melanin is produced by skin cells called melanocytes, and it gives your skin its colour. In vitiligo, there are not enough working melanocytes to produce enough melanin in your skin. This causes white patches to develop on your skin or hair

TAMARIND (Imli) has long been touted as a natural laxative that stimulates your metabolism and further keeps your digestive system strong. Fibre helps smoothen the process of moving the stool easily through your intestinal tract. Tamarind also stimulates the activity of bile that helps dissolve the food quickly speeding up digestion.
Tamarind has traditionally been used as a laxative because it has high amounts of malic and tartaric acids. Tamarind also contains potassium bitartrate, which, along with other active ingredients, relieves constipation.
Constipation and diarrhea often cause abdominal pain. Tamarind bark and root extracts have been proven to be effective in curing stomach ache. In Nigeria, soaked tamarind is eaten to deal with constipation.
