Adequate sleep is essential to stay healthy and maintain your well-being. A peaceful sleep for 7-8 hours is needed for the body’s natural repair and regulation process. It also helps your physiological system recover from stress. Insufficient sleep has negative consequences on the health that directly or indirectly leads to thinning of hair.

Our body undergoes different sleep or circadian cycles that regulate the stem cells and growth of hair follicles. During the anagen stage (hair growth phase) of the hair development cycle, a circadian oscillation results in stem cell development of hair follicles that stimulates hair growth during a particular period of the day (2).

Poor sleep patterns and improper circadian cycle raise the cortisol level (stress hormone) that results in hair loss (3) (4). A study published in the American Journal of Pathology illustrated the relationship between stress levels and hair growth. The release of neurohormones, neurotransmittersi  XSignaling molecules secreted by a neuron that carry chemical signals without which the body cannot function. , and cytokinesi  XSmall membrane-bound proteins that are crucial for the growth and activity of immune system cells and blood cells. related to excess stress level affects the hair growth cycle (5).

However, sleep disorders like insomnia or lack of sleep affect the functioning of the human growth hormone (HGH). A study shows that the night surge of growth hormone is dependent on the sleep cycle. Irregular, limited, or disturbed sleep lower HGH levels, which leads to thinning hair or male/female pattern baldness (6) (7).

Therefore, a regular sleep routine of 7- 8 hours may help manage stress and decrease premature shedding of hair.
