For example, THC is able to alter the functioning of the hippocampus (see "Marijuana, Memory, and the Hippocampus") and orbitofrontal cortex, brain areas that enable a person to form new memories and shift his or her attentional focus.
Short-term cannabis use appears to increase the time you spend in deep sleep, the stage that helps you wake up feeling refreshed. However, THC decreases the amount of time you spend in rapid eye movement (REM) sleep, when you spend more time dreaming, processing emotions, and cementing new memories.
THC (the psychoactive compound in cannabis) binds to endocannabinoid receptors in the brain like the amygdala, which regulates the response to fear-related emotions. Weed that's rich in THC may overstimulate the amygdala, increasing negative emotions that make you feel paranoid and anxious.
Research suggests that wearing socks to bed can help people not only fall asleep faster, but sleep longer and wake up fewer times throughout the night. One study found that young men wearing socks fell asleep 7.5 minutes faster, slept 32 minutes longer, and woke up 7.5 times less often than those not wearing socks.
Wet hair when sleeping also can cause damage to follicles and result in hair breakage. Skin conditions: Hair follicles under the skin clogged up with sebum or oil can result in acne. As wet hair harbors bacteria, this can also impact the growth of bacteria in the pores.
Between the times of 10:00 pm and 2:00 am the body goes through a dramatic process of physical repair. Between roughly 2:00 am and 6:00 am the body will go through a process of psychological repair. A disrupted sleep pattern will cause the Cortisol to elevate and negatively affect the regenerative process.
Teeth are the ONLY body part that cannot repair themselves. Repairing means either regrowing what was lost or replacing it with scar tissue. Our teeth cannot do that. Our brain for example will not regrow damaged brain cells but can repair an area by laying down other scar-type tissue .
Which Part of the Body Heals the Fastest? Muscles and tendons generally heal the fastest. These parts of the body recover more quickly thanks to an ample blood supply. The circulatory system provides muscles with plenty of nutrients and oxygen needed for healing.
Is it OK to sleep in my bra? There's nothing wrong with wearing a bra while you sleep if that's what you're comfortable with. Sleeping in a bra will not make a girl's breasts perkier or prevent them from getting saggy. And it will not stop breasts from growing or cause breast cancer.
When to wash. Rossi generally tells his patients they should wash their hair once or twice per week.

Without a pillow to support the head, side and back sleepers may experience stiffness or soreness in the lumbar or cervical spine. Referred neck pain from not using a pillow may also contribute to tension headaches. Even when stomach sleepers don't use a pillow, neck pain isn't necessarily unavoidable.
Experts recommend washing or changing sheets once a week. In this post we cover how best to do it, tips, and why it's good advice to follow.
Most people should wash their sheets once per week. If you don't sleep on your mattress every day, you may be able to stretch this to once every two weeks or so. Some people should wash their sheets even more often than once a week.
Prolonged periods of not washing can cause cause buildup on the scalp, damaging hair and even impeding its ability to grow, Lamb said. Grime from dirt, oil and hair product can show up within four to six days for people with finer, straighter hair.
Sleeping on your back is your best bet, for two reasons: First, your breasts won't be underneath you or in between your arms, where they'll get in the way and make it harder to sleep comfortably, says Reverie Sleep Advisory Board Member Amelia Bailey, MD.

Wounds that take a long time to heal need special care.
