How you can keep smelling your best. Start personal hygiene regimen that includes taking daily baths or showers, drinking lots of liquids (especially water) to detoxify your body, wearing loose-fitting cotton-based clothing and, if necessary, changing clothes frequently. Also, trimming the hairs in high perspiration areas, such as the underarms, will inhibit the odour-causing bacteria from proliferating. Regular use of a deodorant or antiperspirant will provide extended odour protection. A bedtime application will help you feel fresher in the morning.
