汗と臭い
Sweat is a natural and important bodily function. It regulates body temperature by cooling the skin to avoid overheating.
There are two causes for sweat – environmental and emotional. We often sweat when we are physically active or when we are in a hot environment. Sweat can also occur when we are emotionally affected by professional or personally stressful situations, such as job interviews, presentations or exams. Sweat can also triggered by the hormonal changes associated with puberty and menopause.
Sweat itself is odourless – it is a solution that is primarily made up of water and salt. On average we have 1.6 to 4 million sweat glands all over our body and can produce up to 1 litre of sweat every day. Sweat often evaporates as quickly as it is produced. However, in situations where we are particularly active or in a hot environment, we can sweat up to 10 times a normal day’s production.
Body odour is caused by bacteria on the surface of the skin as it breaks down the components of the sweat.

制汗剤とデオドラント
デオドラント
デオドラントは汗を止めるものではありません。皮膚に生息する細菌から発生する臭いを一時的に中和するように設計されています。多くのデオドラントには、悪臭を隠すための香料が含まれています。
制汗剤
制汗剤は、汗腺での汗の分泌を減らす、あるいは止めるために特別に配合されているという点で異なります。制汗剤を塗ると、汗管に一時的な栓が形成され、汗の放出が止まります。この一時的な栓は、皮膚の自然な剥離の一部として、数日後に自然に除去されます。
デオドラントだけで十分な人もいますが、もう少し保護が必要な人もいます。Perspirex などの効果的な制汗剤は、汗と臭いの両方を大幅に軽減する解決策です。
汗に関する事実
汗は汗腺によって生成されます。私たちの体には数百万もの汗腺があり、それらは 2 つのタイプに分けられます。
脇の下などの毛包に存在するアポクリン汗腺
エクリン汗腺は全身の皮膚表面に存在します
アポクリン汗腺は、主に毛の成長に関連する部位に見られます。これらの腺は思春期に活性化し、皮膚の天然細菌叢により強い臭いを発することがあります。エクリン汗腺は最も豊富な汗腺で、体のほとんどの部位に存在し、手と足の裏に最も集中しています。
Excessive sweating
ほぼ 3 分の 1 の人が毎日発汗の問題を経験していることをご存知ですか?
Excessive sweating is common and can happen to anyone at any time.
Those suffering from excessive sweating often adopt common corrective behaviours, such as avoiding shaking hands or raising their arms.
There are also those who don’t suffer daily but often find themselves in stressful situations where sweat can become an embarrassing problem. Do I smell? Does it show? These people often worry about the possibility of others discovering their problem.
Excessive sweating can range from moderate moisture to the severe, resulting in large sweat patches on clothing; damp and smelly feet; or clammy and wet hands. It is a common problem that can affect anybody at any time in their life, however hormonal changes such as puberty and menopause are often a trigger.
