nicolesy / Getty Images Sleep apnea is a condition that causes breathing to stop and start repeatedly while sleeping. It may occur up to 400 times per night, with each pause lasting 10 seconds or longer. There are two main types of sleep apnea. Obstructive sleep apnea (OSA) occurs when the soft tissues in your throat relax, temporarily blocking airflow. Central sleep apnea occurs when your brain doesn't send the correct signals to the muscles that control breathing.

Cecilie_Arcurs / Getty Images Blue light is part of the visible light spectrum. Many people think blue light is emitted primarily from electronics like phones, tablets, and TV screens, but the largest source of blue light is the sun. The amount of blue light emitted by electronic devices is very low and considered safe. Exposure to blue light can affect sleep quality, alertness, hormone production, mood, and more. Blue light could also contribute to headaches, but other causes may be more likely.

ilona titova / Getty Images Hypersomnia and narcolepsy are both sleep disorders that cause excessive daytime sleepiness and other changes in natural sleep-wake cycles. "Hypersomnia" actually refers to several sleep conditions that cause excessive daytime sleepiness, including narcolepsy and idiopathic hypersomnia (IH), hypersomnia with no apparent cause. These conditions are often misdiagnosed or undiagnosed, but estimates suggest that IH is far more common than narcolepsy.

Guillermo Spelucin / Getty Images Migraines may occur when the nervous system is overly stimulated. The brain mistakenly sends out pain signals, setting off symptoms of a migraine attack: An intensely throbbing headache, nausea, vomiting, and extreme sensitivity to bright lights and loud noises. Migraine medications can help prevent and relieve migraine attacks, but they’re not the only way to treat these painful episodes. Home remedies can speed up the process, helping you feel better faster.

JulPo / Getty Images Sleep is when your body rests, recovers, and repairs itself, essential to your physical and mental health. During sleep, your brain clears waste, stores memories, and keeps brain cells (neurons) working properly. The body makes hormones that help you grow, heal tissues, support metabolism, and strengthen the immune system during sleep. These important processes usually take more than six hours for most adults.
