電子煙和香煙哪個危害大?

Posted by dajksdhj21 on September 18, 2024 at 10:31pm 0 Comments

長久以來,關於電子煙和香煙哪個危害更大的討論未曾停歇。在全球範圍內,吸煙已被證明是導致多種嚴重健康問題的主要原因,包括肺癌、心臟病和慢性阻塞性肺疾病。隨著人們對健康的關注增加,電子菸作為傳統香煙的替代品逐漸流行起來。







電子煙和香煙哪個危害更大仍然是一個備受關注的問題,一起來看看,希望能幫到你。



傳統香煙通過燃燒煙草來釋放尼古丁,同時產生大量有害物質,包括一氧化碳、焦油和數千種其他化學物質,其中許多是已知的致癌物。長期吸煙者面臨著嚴重的健康風險,如肺癌、心血管疾病和呼吸系統問題。香煙的危害已被大量科學研究和公共衛生數據所證實。

Handheld Laser or In-Studio Laser: Which Works Better?

The application of low-level laser light to the scalp to restore hair growth is not entirely new. But the options for how to get it can affect its effectiveness.


Addressing skepticism, several studies have investigated the efficacy of low-level laser hair loss treatment for hair growth. Researchers Pinar Avci, MD and Gaurav K. Gupta, MC, PhD, et al. published their study in the journal Lasers in Surgery and Medicine in 2015 (“Low-level laser (light) therapy (LLLT) for treatment of hair loss,” August 23 2013), and their findings were encouraging.


“LLLT for hair growth in both men and women appears to be both safe and effective,” say the authors, cautioning that the optimum wavelength and other factors were not identified in their clinical research on human subjects. The bulk of prior research on lasers and hair loss, which found that LLLT consistently stimulated hair growth, was with lab animals.


In-home vs. in-studio LLLT

Which begs the next question: is it better to pursue a LLLT treatment strategy in the home or in a hair loss treatment studio? It depends somewhat on the individual.


To decide, consider the following variables of LLLT:

  • Frequency of application affects results. About three treatments per week of 20-30 minute duration are recommended for most patients. Are you willing and able to visit a studio, at a cost, with that frequency? Alternatively, are you disciplined enough to do it on a regular schedule on your own?

  • Doing it correctly matters. A studio will have a more sophisticated set-up that includes a hood that directs the lasers at the correct distance from your scalp, applying a consistent concentration of light in the right places. A handheld, self-administered LLLT places that responsibility on the individual, aided by a comb that ensures the proper distance; that said, helmet versions are available for home use that control for this.

  • Diode power is important. Most in-studio equipment has 150 to 250 diodes per hood, but advertising for at-home lasers rarely provide this information at online shopping sites. This is likely due to the home versions being at lower power.

LLLT works best on male pattern baldness

Interest in LLLT as a hair-restorer goes back decades when use of the technology with laboratory mice incidentally stimulated hair growth. Over time, studies identified that that laser treatment increases blood circulation in the scalp to stimulate the growth of new hairs in humans. It’s generally most effective at addressing androgenic alopecia, male pattern baldness, where hair follicles are blocked from producing new hairs by the hormone DHT. Hair loss medications (finasteride and minoxidil) otherwise block or diminish the effects of DHT.
