If you're experiencing fatigue, it's worth getting a blood test before assuming lifestyle causes. Common deficiencies that cause tiredness include iron (especially in women), vitamin B12, vitamin D, and thyroid issues.
For vitamin D specifically: most people in the northern hemisphere are deficient, especially in winter. Symptoms include fatigue, low mood, muscle weakness, and frequent illness. A blood test will confirm. Supplements are cheap — most doctors recommend 1000-2000 IU daily as maintenance.
Iron deficiency anaemia is also very common, especially if your diet is low in red meat. You might feel exhausted, look pale, get short of breath easily, and have cold hands. Ferrous sulphate tablets are the standard treatment — take with vitamin C to improve absorption.
B12 deficiency is common in vegans and vegetarians since it's mainly in animal products. Symptoms include extreme fatigue, brain fog, tingling in hands and feet. B12 supplements or injections resolve it.
See your GP first — a simple blood test rules out or confirms these quickly.

To sleep better: the most evidence-backed change is keeping a consistent wake-up time every day, including weekends. Your body's circadian rhythm is anchored to your wake time, not your sleep time. Set an alarm for the same time daily for two weeks and don't nap longer than 20 minutes.
Your bedroom should be dark, cool (around 18°C is optimal), and quiet. Use blackout curtains or a sleep mask. Even small amounts of light suppress melatonin. Charge your phone outside the bedroom if possible.
Avoid caffeine after 2pm. Caffeine has a half-life of about 5 hours, so an afternoon coffee still has significant effect at midnight. Alcohol might help you fall asleep but it fragments sleep quality in the second half of the night.
For persistent insomnia, Cognitive Behavioural Therapy for Insomnia (CBT-I) is more effective than sleeping pills long-term. It's available via apps like Sleepio or through your GP.
