Noise-induced Hearing Loss: From 1 Different Sources
Hearing loss caused by prolonged exposure to excessive noise or by brief exposure to intensely loud noise.
Exposure to a sudden, very loud noise, usually above 130 decibels, can cause immediate and permanent damage to hearing. Normally, muscles in the middle ear respond to loud noise by altering the position of the ossicles (the chain of bones that pass vibrations to the inner ear), thus damping down the intensity of the noise. If these protective reflexes have no time to respond, the full force of the vibrations is carried to the inner ear, severely damaging the delicate hair cells in the cochlea. Occasionally, loud noises can rupture the eardrum.
More commonly, noise damage occurs over a period of time by prolonged exposure to lower levels of noise. Any noise above 85–90 decibels may cause damage, with gradual destruction of the hair cells of the cochlea, leading to permanent hearing loss. Prolonged exposure to loud noise leads initially to a loss of the ability to hear certain high tones. Later, deafness extends to all high frequencies, and the perception of speech is impaired. Eventually, lower tones are also affected.
Sounds at 85–90 decibels or above may cause pain and temporary deafness. Prolonged tinnitus (ringing or buzzing in
the ears) occurring after a noise has ceased is an indication that some damage has probably occurred.

If you’ve decided to go on a diet in order to lose weight, you have to be careful with what you drink and eat. Sodas and some juices are a definite no, and while you can drink water all the time, it might get a bit dull. If you want to try something different, and especially pleasant to the taste, tea’s the best choice. Find out more about the perfect teas for weight loss.
Benefits of tea for weight loss
If you drink your tea simple, without sugar, then you’ll enjoy a hot beverage with 0 calories. This at least prevents you from gaining weight.
However, based on the effect one type of tea may have on the digestive system, drinking tea can even help you lose weight. From green tea to oolong tea, each has its own health benefits which help you when you’re on a diet.
Types of tea for weight loss
First of all, green tea is perfect when you’re on a diet. Among its active constituents, green tea has catechin polyphenols, which is quite useful when you want to lose weight. Thanks to this, drinking green tea will increase thermogenesis (the amount of calories which are burned) and fat oxidation. You can drink 4-5 cups of tea a day.
Oolong tea is also helpful if you’re on a diet. It even has a stronger effect than green tea, by speeding up the body’s metabolism and promoting fat burning. If you include it in your diet, don’t drink more than two cups a day.
Peppermint tea is included on the list of teas you can drink while on a diet. Besides the fact that it promotes a good digestion, it helps you burn calories as it speeds up the digestive process.
Other teas that help you lose weight include star anise tea, rose petal tea, as well as various types of herbal teas.
Tea Steeping Time
Steeping time varies from one type of tea to another. If you use teabags, follow the instructions written on the box. If you use dried leaves to make your tea for weight loss, then here are a few steeping instructions.
If you’re drinking green tea, it’s best that you let it steep for about 3 minutes. Steeping time for oolong tea can vary from one minute to 5, based on how strong you want the tea’s flavor to be. And as for peppermint tea, you should let it steep for about 4-5 minutes.
Tips to sweeten your diet tea
If you want to sweeten your tea even when on a diet, you mustn’t use sugar or milk, even if you like those the best. While they won’t add weight, they also won’t help you lose it.
The best solution, in this case, is for you to use honey. Other things you can use to sweeten it are fruit juices (especially lemon juice) and stevia leaves. Based on your preferences and the taste of the tea you choose, you can even combine them.
Caffeine in tea and weight loss
The caffeine found in various types of tea also helps you lose weight. Caffeine acts as a stimulant; therefore it gives you more energy. The more energetic you feel, the more you’re bound to exercise in order to burn more fats. Also, as it acts as a stimulant, it can help reduce your appetite.
Caffeine might not be the only stimulant you’ll find in teas. Other stimulants include ginseng, taurine, and guarnine.
Side effects related to weight loss tea
People who know coffee doesn’t do them good should be careful with teas that contain caffeine. It can cause unpleasant side effects, such as insomnia, anxiety, headache, dizziness, irritability, blurred vision and skin rashes. When you combine your diet tea with a different alimentation and exercising, the side effects might become more unpleasant.
Also, make sure you check the amount of tea that’s recommended for drinking. You can have 4-5 cups of green tea per day, while in the case of oolong tea, it is advised that you drink two cups. The amount varies from one tea to another.
Now, drinking tea for weight loss sounds like a tempting idea. Considering how helpful tea can be when you’re trying to lose weight, make sure you pick one when you go on a diet.... drink tea for weight loss

Alopecia. Baldness. Shedding of the hair in patches leaving glossy bald areas. It is normal to lose about one hundred hairs a day, but severe stress such as unemployment, divorce or death in a family may considerably increase hair loss. Losses of long-standing are seldom recovered.
Causes: hormone deficiency (Agnus Castus) in females, where it may be associated with failing thyroid or ovarian function. In such cases, other agents include: Helonias, Motherwort, Black Haw bark. Other causes may be pregnancy, the menopause, or simply discontinuing The Pill. Certain skin diseases predispose: ringworm (Thuja), eczema (Yellow Dock), from thyroid disorder (Kelp, Blue Flag root).
Exposure to some cosmetics, excessive sunlight, strong chemicals and treatment of cancer with cytotoxic drugs may interfere with nutrition of the hair follicles. To ensure a healthy scalp a correct mineral balance is essential calling for supplementation of the diet with vitamins, selenium, zinc and silica. Yellow Dock is believed to counter toxicity of chemicals; Pleurisy root opens the pores to promote sweat and action of surface capillaries.
Baldness sometimes happens suddenly; eye-lashes or beard may be affected. Though emotional stress and a run-down condition is a frequent cause, most cases are not permanent, returning to normal with adequate treatment.
Baldness of the eyebrows alerts us to a lowered function of the thyroid gland, being an early outward sign of myxoedema. A pony-tail hair style or the wearing of a crash helmet may cause what is known as traction alopecia. Heavy coffee drinkers invariably lose hair lustre.
Soviet Research favours silica-rich plants internally and as a lotion: Horsetail, Burdock, Nettles, Bamboo gum.
Growth of hair is assisted by improving surface circulation of the scalp which is beneficial for conveying nutrients to the hair roots and facilitating drainage. Herbal vasodilators stimulate hair follicle nutrition and encourage growth: Cayenne, Pleurisy root, Black Cohosh and Prickly Ash, taken internally. A convenient way of taking Cayenne is the use of a pepper-shaker at table.

Note: Studies show that male occipital baldness confers a risk of heart disease, being associated with a higher total cholesterol and diastolic blood pressure than men with a full head of hair. Frontal baldness has not been found to be associated with increased risk of coronary heart disease and myocardial infarct. “It seems prudent for bald men to be specially vigorous in controlling risk factors for such conditions.” (S.M.

Inability to speak normally. Temporary partial loss of voice commonly results from straining of the muscles of the larynx through overuse of the voice or from inflammation of the vocal cords in laryngitis. Persistent or recurrent voice loss may be due to polyps on the vocal cords, thickening of the cords in hypothyroidism, or interference with the nerve supply to the larynx muscles due to cancer of the larynx, thyroid gland, or oesophagus. Total loss of voice is rare and is usually of psychological origin. (See also hoarseness; larynx, disorders of.)... voice, loss of

(CROS hearing aid) a form of hearing aid used to help people with severe or profound unilateral hearing loss. Sound information is collected by a microphone worn on the affected side and then transmitted by a thin wire or Bluetooth wireless technology to a device worn on the opposite side. If the hearing in the better ear is normal, no amplification is applied to the signal. If the better ear has a hearing loss the device also acts as a conventional hearing aid and amplifies the signal from both sides: this is known as a BICROS hearing aid.... contralateral-routing-of-signal hearing aid

a device to improve the hearing. Simple passive devices, such as ear trumpets, are now rarely used. An analogue hearing aid consists of a miniature microphone, an amplifier, and a tiny loudspeaker. The aid is powered by a battery and the whole unit is small enough to fit behind or within the ear inconspicuously. If necessary, aids can be built into the frames of spectacles. In a few cases of conductive hearing loss the loudspeaker is replaced by a vibrator that presses on the bone behind the ear and transmits the sound energy through the bones of the skull to the inner ear. Digital hearing aids are in some respects similar to analogue aids but in addition to the microphone, amplifier, and loudspeaker, they have digital-to-analogue converters and a tiny computer built into the casing of the aid. This enables the aid to be programmed to the patient’s particular requirements and generally offers improved sound quality.
