The human body produces the hormone melatonin. This hormone has been confirmed by researchers to regulate the sleep cycle and increase hair growth. While sleep has a direct impact on the human body's natural hormones, it means that poor sleep reduces the amount of melatonin, potentially cause hair loss.
National Institutes of Health advises that sleep may affect your hair health. A good night's sleep will help restore and adequately synthesize hair protein, release enzymes and growth hormones needed to ensure healthy hair.
Getting the recommended 7-9 hours of quality sleep every night is vital to maintaining a full and healthy head of hair.
“We know that hair grows in cycles, and these cycles are circadian. Thus, sleep deprivation will certainly change the hair growth cycle (most likely making it worse). In addition, we know that hair growth is related to Human Growth Hormone release, which is primarily seen in stages 3 and 4 sleep.”
Stress and hair loss don't have to be permanent. And if you get your stress under control, your hair might grow back. If you notice sudden or patchy hair loss or more than usual hair loss when combing or washing your hair, talk to your doctor.
Telogen effluvium hair loss — the type of hair loss linked to stress — typically affects your scalp and may appear as patchy hair loss. However, it can also cause you to shed more body hair or notice less hair on your body than you normally would.
Long-term, or chronic, stress puts people at risk for a variety of health problems. These can include depression and anxiety, as well as problems with digestion and sleep. Chronic stress has also long been linked to hair loss, but the reasons weren't well understood.
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
The answer to this frequently asked question is no. Your sleeping position whether it be on your side or back doesn't stop nutrients from getting to your scalp. Nor does it prevent blood from flowing to the hair follicles.
There are a wide range of conditions that can bring on hair loss, with some of the most common being pregnancy, thyroid disorders, and anemia. Others include autoimmune diseases, polycystic ovary syndrome (PCOS), and skin conditions such as psoriasis and seborrheic dermatitis, Rogers says.
Proper sleep is important for your hair. Beyond affecting your ability to produce adequate amounts of human growth hormone, sleeping helps with your production of melatonin which has been linked to hair growth.
For those whose sleep was tracked at age 50, people who slept five hours or less a night faced a 30% higher risk that they would develop multiple chronic diseases over time than those who slept at least seven hours a night. At 60, it was a 32% increased risk, and at 70, it was a 40% greater risk.
Many men wonder whether they need to pursue treatment to reverse the effects or if they can grow the hair back on their own. Although hair re-growth may be possible, you should also know when to seek professional help. If the reason for thinning hair is genetics, it will not grow back on its own.
Telogen hair, or 'resting' hair, comprises around 15% of the hair on a person's scalp. Periods of elevated stress can lead to this hair being temporarily lost, contributing to a visibly thinner scalp and hairline.
When to see a doctor. See your doctor if you're concerned about how much hair you are losing every day. A gradual thinning on the top of your head, the appearance of patchy or bald spots on your scalp, and full-body hair loss are signs that there may be an underlying health condition.
The hair loss is temporary, and should return to its pre-effluvium density, although this process is generally slow. It can take months (but generally less than 6) before the shedding stops, and then months to years for lost hair to grow back at the sluggish rate of ~½ inch per month.
