When consumed at bedtime, alcohol has an initial stimulating effect among nonalcoholics, followed by a decrease in time to fall asleep (NIAAA, 1998). Little is known about how the different substances of abuse affect sleep in humans, although there are more data on alcohol's effect.
>Effect of Alcohol and Substances of Abuse on Sleep There are about four occurrences of REM in total, the first is shortest and the last is usually longest (NIAAA, 1998). Normally present every 90 minutes, the REM stage lasts five to 30 minutes and is associated with dreaming, but no clear function is known for it. Restful SWS has the lion's share of sleep time, while REM sleep occurs periodically, resulting in about 25% of sleep time in the young adult. There is slow wave sleep (SWS), during which the brain waves are very slow (commonly referred to as Stage III and IV), and rapid eye movement (REM) sleep, in which the eyes undergo rapid movements although we remain asleep. Two states of sleep alternate throughout the night, characterized in part by different types of brain electrical activity (National Institute on Alcohol Abuse and Alcoholism, 1998). People who abuse alcohol and other substances are at high risk for sleep disturbances due to the direct effect of the substance or its withdrawal on their sleep architecture and their sleep-wake cycle or its effect on their behavior and daily functioning, which in turn impacts their daily need for sleep. On the other hand, nighttime sleep disturbance is usually followed by excessive daytime sleepiness that is associated with delayed problems like memory deficits and impaired social and occupational function, and immediate consequences such as car accidents (Kupfer and Reynolds, 1997 Roehrs and Roth, 1995). What we do know is lack of sleep can have serious implications, such as increased risk of depressive disorders, impaired breathing and heart disease.

If you aren’t sure of the cause of your itchy scalp, it’s always best to see a professional for help and a customized treatment plan.Despite the fact that about 30% of our life is spent sleeping and decades of research have been spent on sleep, we still do not know its real function. If the cause of your itchiness is dandruff, “it's best to use anti-dandruff shampoos that contain ketoconazole, zinc pyrithione, or selenium sulfide these particular ingredients help to reduce the yeast associated with dandruff and reduce itching,” Garshick says. Then apply a hydrating shampoo and conditioner.

When you do wash, first apply a pre-shampoo treatment that contains antimicrobial oils such as rosemary or peppermint these oils protect skin from the drying effects of washing while also nourishing the scalp and helping to keep it clear of impurities. The best way to treat an itchy scalp is to employ the process of elimination, Hill says: “Rule out sensitivities and allergies to products, accessories, and tools, and ensure shampoos and styling products are thoroughly rinsed out of the hair.” If your scalp is dry, start to wash your hair less often to avoid stripping the skin of its natural oils.

“Itchiness and irritation with the presence of lesions, flakes, and scaling can be the result of seborrheic dermatitis, also known as dandruff.” How to treat itchy scalp? Dermatitis is a common skin condition that involves dry, itchy, and rash-y skin. “Severe itchiness and irritation without any lesions can be a symptom of a type of dermatitis,” says Hill. Other causes, like dandruff or dermatitis, require more tedious treatments. The solve for a dry scalp is relatively easy (moisturize!).
Extremely warm or cold temperatures also contribute to dryness and itchiness, explains Garshick. “Over-washing your hair can strip the scalp of its natural oils and contribute to dryness, which can cause itchiness.” On the other hand, under-washing your hair can lead to product and oil buildup, which can also cause irritation and dryness. “Specific factors that may contribute to an itchy scalp include product irritation, washing too frequently or not frequently enough, environmental changes, and a history of skin conditions,” says Marisa Garshick, a board-certified dermatologist at MDCS Dermatology. Here, experts explain how to deal with an itchy scalp, including its causes and the best products to buy.
But no matter the root cause, a healthier, calmer scalp is achievable with this expert advice and some effective products. First, know that an itchy scalp is a symptom of a number of issues: dry or dehydrated skin, dandruff, dermatitis, psoriasis, or irritation from something you're using, says Bridgette Hill, a certified trichologist at René Furterer. It's worth it to get to the bottom of this common concern. Sometimes dealing with an itchy scalp isn't just a minor annoyance-it can impact your quality of life, lowering confidence, causing discomfort, or making you feel embarrassed.
