5 Things to Do When You Can't Sleep
Lying awake at 2 a.m. with your mind racing and your body refusing to cooperate is one of the most frustrating experiences in modern life — and one of the most common. Whether you struggle to fall asleep, wake repeatedly through the night, or find yourself staring at the ceiling before dawn, the impact on your health, mood, and daily function is real and cumulative. Here are five evidence-based strategies for improving sleep, along with an important explanation of why hormones are often the underlying cause that these strategies alone cannot fully address.
1. Protect Your Sleep Window with Consistent Timing
The single most powerful behavioral intervention for sleep is maintaining a consistent sleep schedule — going to bed and waking at the same time every day, including weekends. This practice anchors your circadian rhythm, strengthening the biological clock that coordinates cortisol, melatonin, body temperature, and dozens of other timed processes. Irregular sleep timing — varying your bedtime or wake time by more than an hour — undermines circadian rhythm integrity and makes falling and staying asleep significantly harder.
Set a consistent wake time first, even before you address bedtime. Waking at the same time each morning — regardless of how well you slept the night before — builds sleep pressure (adenosine accumulation) throughout the day that makes falling asleep easier the following night. Over one to two weeks of consistent timing, most people notice measurable improvement in sleep quality.
2. Create a Sleep-Promoting Environment
Your sleeping environment has a direct physiological impact on sleep quality. Core body temperature needs to drop by approximately one to two degrees Fahrenheit to initiate and maintain deep sleep. A cooler bedroom — ideally between 65 and 68 degrees Fahrenheit — facilitates this necessary temperature drop. Complete darkness is equally important: even small amounts of light reaching the retina can suppress melatonin production and delay sleep onset.
Blue light from phones, tablets, and computers suppresses melatonin for two to three hours after exposure. Establishing a screen-free wind-down period of at least 60 minutes before your target sleep time allows melatonin to rise appropriately and the nervous system to shift into rest mode. Replace screens with low-light, low-stimulation activities: reading physical books, light stretching, journaling, or conversation.
3. Use a Structured Wind-Down Routine
The transition from wakefulness to sleep is not instantaneous — it requires a physiological downshift that takes 30 to 60 minutes in most adults. A consistent pre-sleep routine signals to the brain and body that sleep is approaching, facilitating the autonomic shift from sympathetic (alert, active) to parasympathetic (calm, restful) dominance. Effective wind-down elements include a warm bath or shower (which paradoxically lowers core body temperature through skin vasodilation after exiting the water), light stretching or yoga nidra, diaphragmatic breathing, progressive muscle relaxation, and journaling to offload the day's cognitive load.
What to avoid in the two to three hours before bed: vigorous exercise (raises core temperature and cortisol), alcohol (fragments sleep architecture after initial sedation), large meals (digestion elevates body temperature and stimulates the gut), and emotionally activating content (news, social media conflict, suspenseful entertainment).
4. Address Anxiety and Cognitive Hyperarousal Directly
Cognitive hyperarousal — the racing mind that makes falling asleep feel impossible — is among the most common complaints of chronic insomnia. When anxious or worrying thoughts activate the amygdala and default mode network, the brain enters a high-arousal state incompatible with sleep onset. Two evidence-based tools for addressing this are cognitive behavioral therapy for insomnia (CBT-I) and stimulus control therapy.
CBT-I challenges and reframes unhelpful beliefs about sleep ("I must get eight hours or tomorrow will be ruined") and teaches practical techniques for breaking the anxiety-insomnia cycle. Stimulus control involves reserving the bed exclusively for sleep (and sex), training the brain to associate the bed with sleepiness rather than wakefulness. If you have been lying awake for more than 20 minutes, get up, go to a dim room, and do something quiet until sleepy — then return to bed. Breaking the association between bed and wakefulness is one of the most effective long-term insomnia interventions available.
5. Audit Your Stimulants and Depressants
Caffeine has a half-life of approximately five to six hours in most adults — meaning that a 2 p.m. coffee still has half its stimulant effect present at 7 or 8 p.m. Caffeine blocks adenosine receptors, the brain's sleep-pressure signaling system, delaying sleep onset and reducing deep sleep duration even when it does not prevent falling asleep. Moving your last caffeine intake to before noon, or eliminating it entirely if you are a poor sleeper, often produces meaningful improvements within days.
Alcohol is perhaps the most misunderstood sleep substance. While it does facilitate initial sleep onset through GABA-agonist sedation, it fragments sleep architecture in the second half of the night as it is metabolized, suppresses REM sleep, and worsens sleep apnea. Regular alcohol use before bed guarantees worse sleep quality even when it appears to "help."
When Hormones Are the Hidden Cause
These five strategies are genuinely effective — and for many people, implementing them consistently produces substantial improvement. But for a significant portion of people dealing with chronic insomnia, they provide only partial relief, because the underlying cause is hormonal rather than behavioral.
Progesterone deficiency removes the brain's primary endogenous calming signal. Estrogen deficiency produces the night sweats and temperature instability that shatter sleep continuity. Elevated evening cortisol from adrenal dysfunction creates the "wired at bedtime" state that no amount of wind-down routine can fully overcome. Hypothyroidism impairs sleep quality through slowed metabolism and, in some patients, sleep apnea. Low testosterone in men disrupts sleep architecture and is bidirectionally linked with sleep apnea. Until these hormonal causes are identified and addressed, behavioral sleep strategies will treat symptoms rather than the root problem.
Take the Next Step Toward Restorative Sleep
If you have been implementing good sleep hygiene practices and still struggle with chronic poor sleep, a comprehensive hormonal evaluation may be the missing piece.
