Speech-language pathologists can earn the Certificate of Clinical Competence in Speech-Language Pathology (CCC-SLP), offered by the American Speech-Language-Hearing Association. Certification satisfies some or all of the requirements for state licensure and may be required by some employers.
The effect of lavender on sleep has also been studied. The inhaling of lavender odour during sleep has been observed to reduce the respiration frequency (you breathe in and out less), which is commonly used as an indicator of relaxation and sleep depth.
Lavender is applied to the skin for hair loss (alopecia areata) and pain, and to repel mosquitoes and other insects. Some people add lavender to bathwater to treat circulation disorders and improve mental well being. By inhalation, lavender is used as aromatherapy for insomnia, pain, and agitation related to dementia.
